Erection Problems (Erectile Dysfunction) - Medications

creutzfeldt — Mon, 26 May 2008 15:13:08 +0000

erection problems (erectile dysfunction) that are
caused by blood vessel (vascular), hormonal, nervous system, or psychological
problems. They also may be used along with counseling to treat erection
problems that have psychological causes.

If erection problems could be caused by a
prescribed medication, it may be possible to change
the dose or try another medication. Do not change or stop taking any medication
without first talking with your health new treatment for erectile dysfunction.

Medication Choices

Commonly used oral medications include:

Phosphodiesterase-5 inhibitors (PDE-5
inhibitors) such as Viagra, Levitra, and Cialis.

Other medications that may be used include:

Injected medications.
Ed meds
alprostadil (MUSE).

Hormones and other medications may be prescribed for
men who have low
testosterone or high
prolactin levels.

Some men have tried
yohimbine-a prescription medication that should not be
confused with the dietary supplement yohimbe-to treat erection problems.

What To Think About

PDE-5 inhibitors and heart problems

Health experts have debated the use of PDE-5 inhibitors in men
with heart disease, because deaths have been reported after use of Viagra. The
1999 American College of Cardiology/American Heart Association (ACC/AHA) Expert
Consensus Document noted that PDE-5 inhibitors may be dangerous for people
who:³

Have
coronary artery disease (CAD).
Have
heart failure and low blood pressure.
Are
taking many different drugs for
high blood pressure.

However, several more recent studies have reported that some
men with heart problems may be able to take PDE-5 inhibitors safely. Talk to
your health professional about whether PDE-5 inhibitors are appropriate for
you.

One study found no evidence of increased
risk for
heart attack or CAD in men who use Viagra.⁴
Another study in men with CAD reported that
Viagra does not lead to heart attack and that heart attacks and other
cardiovascular problems reported after taking Viagra may be related more to the
physical activity of intercourse than to the medication.⁵
A study of 35 men found that Viagra is safe for
men with moderate heart failure.⁶

Sexual activity is exercise. If you have a heart condition and
have not been sexually active for a while, talk with your health professional
to make sure you can engage in sexual activity safely.

PDE-5 inhibitors should never be used if
you may need to take a
nitrate-containing medication, such as dysfunction pill
.
Taking nitroglycerin and a PDE-5 inhibitor within 24 hours of each other may
greatly lower your blood pressure, which could lead to a heart attack,
stroke, or death.

If you are taking a PDE-5 inhibitor and are going to have a test
for heart disease, be certain your doctor knows you are taking it. You should
not take a PDE-5 inhibitor for 24 hours before the test. If you develop a
problem during the test, nitrate-containing medications such as nitroglycerin
may be used.

Although oral medications for erection problems can be purchased over the Internet, you should still talk with your health professional before using this medication. This is especially important if you have a heart problem.

If you are using a combination of drugs for high blood pressure,
PDE-5 inhibitors could result in low blood pressure (hypotension). Also for
this reason, you should not take alpha tadalafil online
to lower blood pressure
and to treat an enlarged prostate-with these medications without talking to
your health professional; the combination could cause a dangerous drop in blood
pressure.

Although the antidepressant medication trazodone has been used
for treating erection problems, there is no current evidence that it is
effective for this purpose.¹

ED Drugs May Treat Urinary Problems

creutzfeldt — Sun, 25 May 2008 14:21:04 +0000

May 22, 2007 — Medications commonly used to treat erection problems in men
may also relieve the bothersome urinary symptoms associated with an enlarged
prostate gland, dysfunction pills
say.

Studies on the topic were presented this week at the annual meeting of the
American Urological Soft tablet tadalafil
in Anaheim, Calif.

“Before, we looked at these two conditions as two different
diseases,” says Kevin McVary, MD, professor of urology at Northwestern
University Feinberg School of Medicine in Chicago, who moderated a press
briefing.

But in the past three or four years, he says, the thinking among urologists
has changed.

Sexual performance in men seems to decline as their prostate dysfunction pill

becomes more severe, experts have begun to notice. Doctors also notice
that men with milder prostate problems often have less erectile dysfunction
(ED) than do those with moderate or severely enlarged prostates and urinary
symptoms.

“These two diseases — erectile dysfunction and the lower urinary tract
symptoms associated with benign prostatic hyperplasia — are probably
linked,” McVary says.

Conditions Increase With Age

Prostate problems and ED problems both tend to increase with age. About 31%
of men aged 50 to 59 have an enlarged prostate (also known as benign prostatic
hyperplasia or BPH); 44% of those 70 and older have an enlarged prostate,
according to the National Institutes of Health. As the gland enlarges, it
constricts the urine-carrying tube called the urethra, making it difficult to
empty the bladder.

Common symptoms of BPH include weak urine stream, leaking or dribbling,
feeling that the bladder hasn’t emptied completely after voiding, and more
frequent urination.

Medications are prescribed to relieve the symptoms. Some medications work by
relaxing the muscles at the neck of the bladder and prostate; others inhibit a
hormone that contributes to the growth of the gland.

Erectile dysfunction, defined as an inability to get or keep an erection, is
experienced by 20% to 46% of men aged 40 to 69, according to the NIH.
Medications to treat erection problems help increase blood flow to the penis
when a man is sexually stimulated.

Cialis Study

A once-a-day dose of Cialis helped men with erectile dysfunction and
moderate to severe urinary tract symptoms due to an enlarged prostate improve
sexual functioning, says Marc Gittelman, MD, a urologist in Aventura, Fla., and
a study researcher.

Of the 281 men who enrolled in the study, “81% were sexually active, and
they were in their low 60s,” he says. All had moderate to severely enlarged
prostates and urinary problems; 68% of the sexually active men had a medical
history of erectile dysfunction. Gittelman’s team assigned about half to take
placebo and half to take Cialis.

At the end of 12 weeks, men who took Cialis — first 5 milligrams a day and
then up to 20 milligrams — had significantly higher scores on a standard index
of erectile function, he says.

He especially wanted to see if they were as likely to do well if their
urinary problems were severe as opposed to moderate. “They are equally
statistically likely to respond to a dose of Cialis,” he says.

The study was funded by Lilly, which is the maker of Cialis.

In another study, 223 men aged 45 to 64 who had urinary symptoms due to an
enlarged prostate were assigned either to a group given 10 milligrams of
Levitra twice daily for eight weeks or a placebo for the same time period.

Compared with placebo, treatment with the ED drug significantly improved the
men’s quality-of- life scores and their reports of urinary obstruction and
irritation, says Boris Schlenker, MD, a urologist at
Blindness causing citrate sildenafil Hospital in Munich, Germany, who presented the
data. Erectile function improved in those who took the ED drug.

“Levitra is a promising new drug for men with lower urinary tract
symptoms, but we need long-term data on how it might affect the progression of
the disease,” he says.

The Viagra Study

In a third study, McVary assigned 369 men aged 45 and up who had both
erectile dysfunction and lower urinary tract symptoms to take either 50
milligrams of Viagra every night, 50 milligrams of Viagra an hour before
planned sexual activity, or to take a placebo. The dose increased to 100
milligrams after two weeks.

When he evaluated their erectile function and urinary symptoms, he found 73%
of the men with severe symptoms improved to having mild or moderate symptoms at
the end of the study.

“The changes in prostate symptom scores were dramatic,” he says.
“They compete with alpha blockers.” Alpha blockers are one type of drug
commonly prescribed to treat urinary symptoms associated with an enlarged
prostate. The more severe the urinary symptoms, the greater the
relief, he says.

The study was funded by Pfizer, which is the maker of Viagra.

“This really is cutting-edge,” says Gittelman.

The experts aren’t sure if the ED drugs will eventually supplement or
replace drugs used for urinary problems associated with an enlarged prostate,
or if new formulations might be developed to deal with both conditions.

Some men on the ED drugs did report side effects, says Schlenker, with the
most common in his study being headache.

It’s not known exactly why the ED drugs also help the urinary symptoms,
McVary says. By increasing blood flow to the pelvic area, the ED drugs may help
relax the bladder enough to relieve the urinary problems.

Sexual Problems in Women - Medications

creutzfeldt — Sat, 24 May 2008 12:22:35 +0000

sexual problems are often complex and interrelated.
Medications may be used in treating certain conditions that contribute to
sexual problems.

Medication Choices

Estrogen. If you only have vaginal
dryness and irritation (and not other symptoms such as hot flashes), you can
use a limited amount of
estrogen in a cream, tablet, or ring in the vagina.
The daily estrogen makes your tissue less thin and sensitive and more moist.
Many women find that using a cream or tablet twice a week is enough. This may
increase vaginal tone and lubrication, which will decrease
vulvar dryness, irritation, and shrinkage (atrophy).

If you also have other
menopausal symptoms that affect physical and mental
well-being, talk to your health professional about taking daily (systemic)
estrogen therapy.
Estrogen can increase the blood flow in the
vagina, as well as reduce hot flashes and other
symptoms of
menopause.
Estrogen therapy or
estrogen-progestin therapy can be oral (pills),
vaginal, or transdermal (with a patch). In a small number of women, hormone
therapy causes heart disease, breast cancer, dangerous blood clots, stroke, and
dementia. Talk to your health professional about whether this therapy is right
for you.

Testosterone. This hormone may play a part
in a woman’s sex drive and erectile dysfunction medication
. The ovaries make
erectile dysfunction medication
throughout a woman’s lifetime. Women have
the most testosterone in early adulthood; testosterone levels drop by half
between the early 20s and the early 40s.

In women who have their ovaries removed (oophorectomy),
testosterone drops by 50%.¹⁰ If you have had an
oophorectomy, your health professional may suggest trying
testosterone therapy. But the U.S. Food and Drug
Administration (FDA) has not approved any testosterone therapy for women.

What To Think About

The ed meds
formula called Estratest is
not approved by the FDA. The company that makes it
markets it for moderate to severe
menopausal symptoms. It is also prescribed to some
menopausal women to improve sexual desire and
response. But Estratest is made with
methyltestosterone, which the body uses differently than testosterone. It does
not directly raise the amount of testosterone in your body. And, taking a
testosterone by mouth does put you at risk for problems with your liver and
possibly your heart. Using a patch or cream does not.

At this time, there is no testosterone pill, patch, or cream
approved for women-those made for men have too high a dose for women. Side
effects of too much testosterone include acne, facial hair, and loss of hair
and a deepening of the voice, which may be permanent.

No studies have looked at the benefits and risks of taking
testosterone for longer than 6 months. The long-term effects of testosterone
therapy in women are not known.¹⁰

Sildenafil (Viagra) is used to treat
erectile dysfunction in men. The maker of this
medicine has decided not to market it for improving women’s sexual desire and
arousal. This was based on research showing that sildenafil was not effective
for most women. The maker has commented that women’s sexuality is a complex mix
of physical, emotional, and levitra vs viagra
factors, and it is not as simple to
treat with a medicine as male erectile dysfunction is.¹¹

Currently no medications are approved by the FDA to treat female
sexual problems, although several paths are being studied, including
natural remedy for erectile dysfunction
of certain molecules (receptors) in the brain and increasing blood
flow to the genitals. It is still too early in the process to know whether any
of these medications will prove to be effective and safe treatment
options.¹²

health professional you are taking this medication. Do
not use any form of site sys.kcn.ru vardenafil if you have chest pain and have taken
Viagra, Levitra, or Cialis in the past 24 hours.

Call a health professional if erection problems occur with:

Any type of injury to the back, legs, buttocks,
groin, penis, or testicles.
A loss of pubic or armpit hair and an
enlargement of the breasts.

Make an appointment to see a health professional within 1 to 2
weeks if an erection problem occurs more than 25% of the time and the
problem:

Occurs with a persistent
backache.
Occurs after you start taking a new medication or change
the dose of a medication.
Is affecting your self-image or sense of
well-being.
Has not improved despite self-care.

If your erection problem is occasional, there is no reason to call
your health professional. If it occurs frequently but does not bother you or
your partner, you may or may not choose to call your doctor. However, an
erection problem that develops suddenly may be a sign of a disease; it is
recommended that you see your doctor.

Watchful Waiting

Watchful waiting is a period of time during which you and your
health professional observe your symptoms or condition without using medical
treatment. A single episode of an erection problem is often a temporary and
easily reversible problem. Do not assume it will happen again. If possible,
forget about it and expect a more successful experience the next time. If you
or your partner is concerned about it, talk about the problem and openly
discuss your fears and anxieties.

If self-care has not helped after 2 weeks and you are concerned
about your inability to have an erection, see a health professional who has
experience in dealing with erection problems.

Who To See

Some health professionals, including doctors and mental health
professionals, may not feel ed meds
discussing sexuality and erection
problems. Ask your health professional if he or she feels comfortable with and
has experience in working with men who have erection problems.

The following health professionals can evaluate symptoms of
erection problems:

Family medicine
doctor
Internist
Nurse
practitioner
Physician assistant
Urologist

If it is possible that a erectile dysfunction remedy
problem is contributing to
your erection problem, your doctor may refer you to a health professional such
as a:

Psychiatrist.
Psychologist.
Certified licensed social
worker.
Counselor with special training in sexuality or

Drug May Ease Pulmonary Hypertension

creutzfeldt — Thu, 22 May 2008 00:09:09 +0000

Nov. 16, 2005 — A drug called Revatio may help treat an aggressive condition called pulmonary arterial hypertension.

Patients with pulmonary hypertension have elevated blood pressure in the pulmonary (lung) blood vessels. The condition often arises from lung problems, but some cases are without a known cause. It can result in heart failure and early death.

Unfortunately, most of the medications that are used to treat this serious condition are not easy to take and are given by IV, injection, or inhalation — with real risks of unwanted side effects.

Revatio has the same active erectile dysfunction pill
— sildenafil — as Viagra. Revatio and Viagra are made by Pfizer.

Pfizer funded the new study, which appears in The New England Journal of Medicine. Pfizer is a WebMD sponsor.

The researchers included Nazzarene Galie, MD, of the cardiology institute at Italy’s Pills
of Bologna.

Walking Test

The study lasted for 12 weeks. It included 278 patients with pulmonary hypertension. The patients lived in the U.S., Mexico, South America, Europe, Asia, Australia, South Africa, and Israel.

Three times daily, the patients took Revatio (20, 40, or 80 milligrams) or an empty drug (placebo) orally. That was in addition to any other standard pulmonary hypertension medications.

The big question was how far patients could walk in six minutes. That’s an important exercise test for patients with pulmonary hypertension. The farther patients can walk, the better.

Walking Farther

All of the patients taking Revatio walked farther at the end of the study:

20-milligram group: Walked about 148 extra feet (a 13% increase).
40-milligram group: Walked about 151 extra feet (a 13% increase).
80-milligram group: Walked about 164 extra feet (nearly a 15% increase).

Higher doses didn’t bring a notable increase in distance walked, the researchers report.

Patients were then allowed to take Revatio for up to a year; 230 did so. The researchers looked at the walking tests of 222 of those who were only taking Revatio as treatment. After a year, they walked about 167 extra feet, on average, compared with the beginning of the study.

How Patients Fared

Most of the patients included in the study had milder stages of pulmonary hypertension. Few cases worsened, regardless of treatment type, the study shows.

Patients taking Revatio weren’t any more or less likely to have their symptoms worsen during the trial.

The study wasn’t designed to see if Revatio helped patients live longer. Four died during the study. No deaths were judged to be linked to the erectile dysfunction new drugs
, write the researchers.

Side effects seen with Revatio were mild or moderate and included headache, flushing, muscle pain, and diarrhea, report Galie and colleagues.

Heart Drug for Female Sexual Disorder?

creutzfeldt — Tue, 20 May 2008 23:30:46 +0000

July 24, 2006 — Like Viagra before it, a drug once studied to treat heart problems may help treat sexual dysfunction. But this time it’s being tested exclusively for women.

A new study shows that a modified version of the experimental heart drug Candoxatril was effective at caverta generic viagra
blood flow to the vagina in animal tests.

If further research confirms these results in humans, the drug may be used to treat female sexual arousal disorder (FSAD).

Erectile dysfunction pills
say an estimated 40% of women suffer from FSAD or other forms of sexual dysfuction, such as low libido or pain during sildenafil citrate india.

Candoxatril went into clinical trials in the 1990s as a heart failureheart failure medication but has since become the focus of efforts to develop a medication to treat female sexual arousal disorder.

How the Drug Works

Candoxatril is one of several compounds that targets levels of vasoactive intestinal peptide (VIP), which controls blood flow to the vagina. Researchers say decreased blood flow to the vagina is thought to be a key factor in female sexual arousal disorder.

An enzyme called NEP degrades VIP in the body, and Candoxatril works by blocking NEP.

In a new study, published in the Journal of Medicinal Chemistry, researchers altered the molecular structure of Candoxatril in order to focus the drug to treat female sexual arousal dysfunction.

In animal tests, researchers at Pfizer Global Research and Development in the U.K., found the new compound effectively blocked NEP, took effect quickly, and the effect lasted for a relatively short time.

They say the results suggest that the drug might have similar effects in humans, but further research is needed.

Viagra May Treat Other Ailments

creutzfeldt — Mon, 19 May 2008 23:07:40 +0000

Nov. 7, 2005 - The drug made famous for its treatment of erectile dysfunction appears to have another sildenafil citrate 100mg use.

A study in the journal Circulation suggests Viagra could help treat a circulatory disorder called Raynaud’s phenomenon, which affects about 5% of the population. Raynaud’s phenomenon can be associated with other diseases such as lupus.

Raynaud’s phenomenon causes episodes of numbness, tingling, and pain in the fingers and toes, as well as skin sores or gangrene in severe cases. The attacks are spawned by spasms in small blood vessels in response to cold temperatures or emotional stress.

These spasms cause blood vessels to constrict and compromise blood flow to distal areas such as toes and fingers. The disorder is sometimes treated with medications to relax the blood vessels, but this is not always successful.

The Viagra study involved 18 patients (mostly women) whose Raynaud’s symptoms were not responsive to conventional therapies. While taking Viagra twice a day for four weeks, the patients experienced improved blood flow in the capillaries and fewer Raynaud’s attacks. Symptoms improved and the duration of attacks was also shorter. In those who had skin sores, the ulcers began to heal visibly.

These effects did not occur while patients were taking a placebo. At the end of the study, 16 of the participants asked to continue taking Viagra off-label (that is, for a purpose other than its FDA-approved use).

Viagra causes blood vessels to dilate in a different way from other erectile dysfunction
drugs, which may explain why it helped Raynaud’s patients who didn’t respond to standard treatments. The researchers conclude that drugs like Viagra could offer “a promising new approach in patients with microcirculatory disorders.”

Although Viagra has risk for serious side effects such as heart attack, stroke, and vision loss, none of the study participants reported any such adverse effect. The side effects reported by study participants included headache, muscle pain, flushing, mild nausea, dizziness, and nasal congestion.

One of the researchers has served as a consultant and speaker for Viagra’s erectile pill, Pfizer. Pfizer is a WebMD sponsor.

Viagra May Help Crohn’s Disease

creutzfeldt — Sun, 18 May 2008 14:15:35 +0000

Feb. 23, 2006 — Researchers in the U.K. have a new theory to explain the cause of Crohn’s disease, and they say erectile dysfunction treatment
like the erectile dysfunction drug Viagra may prove useful for treating the bowel disorder if they are right.

In Crohn’s disease, chronic inflammation causes ulcers within the digestive tract that can lead to severe gastrointestinal symptoms, including abdominal pain, persistent diarrhea, and rectal bleeding.

The most widely accepted theory is that an overactive immune system causes the damaging inflammation. But researchers from the University College London say the opposite appears to be true.

They believe a weaker-than-normal immune response triggers the bowel inflammation that leads to Crohn’s disease. Their research appears in the Feb. 25 issue of The Lancet.

1 Disease, 2 Theories

The prevailing theory of Crohn’s disease is that the body’s immune system reacts abnormally in people with the disorder, producing chronic inflammation that leads to bowel injury.

Tony Segal, professor of medicine at University College London, explains the weak immune system theory like this: “The wall of the bowel is normally an effective barrier against the bowel contents, but sometimes the barrier is broken by an infection or injury and the bowel contents, which include large numbers of bacteria, penetrate into the bowel wall.

“Normally, an acute inflammatory response would kick in to remove the bacteria and return the condition of the bowel to normal. But in Crohn’s disease, we think that the acute inflammation fails to kick-start, leaving bacteria to fester in the bowel wall which, in turn, triggers chronic, secondary inflammations.”

Segal and colleagues conducted a series of small experiments that measured white blood cell production in response to intestinal and skin trauma in both Crohn’s patients and healthy patients. With inflammation, white blood cell numbers are expected to rise. In one experiment, researchers injected a killed gut bacteria into the forearms of patients and healthy participants to study blood flow and immune response.

They found that the Crohn’s patients produced levitra vs cialis
lower levels of white blood cells and proteins involved in inflammation, compared with people without the disorder.

Segal tells WebMD that people who carry a gene that has been linked to Crohn’s disease may be especially vulnerable to getting the disease if they have weak immune systems.

He added that drugs like Viagra, which open the blood vessels and increase blood flow, may help.

The Viagra Response

The researchers tested this theory by treating 10 Crohn’s patients with 50 milligrams of Viagra after injecting them with the killed gut bacteria. They found that blood flow to the infected area improved.

“Increasing blood flow is an important part of the inflammatory response, and that is why this drug may work,” Segal says. “But we don’t yet know if this will give rise to successful treatment. We need to study this further to find out.”

Segal and colleagues are among a growing number of researchers suggesting that a weak immune system, rather than an overactive one, is largely ed medicine
for Crohn’s disease, says University of Chicago associate professor of medicine Sunanda Kane, MD.

She adds that the new research adds generic research viagra
to the theory but does not prove it.

“This is a little more evidence that maybe we have been barking up the wrong tree,” she tells WebMD. “The idea that we should be strengthening the immune system — rather than suppressing it — sounded a little crazy at first, but the evidence continues to come in. But we still have a long way to go to really understand what causes Crohn’s.”

Biologic agents that stimulate a specific part of the immune system are now being tested in Crohn’s patients. If such treatments prove effective, Kane says doctors would have an effective alternative to steroids, which work well for many patients but have many side effects.

“For decades now suppressing the immune system with steroids has worked, and we will continue to do so until we find alternatives that work for everybody and are risk-free,” she says.

Viagra: Treatment for Lung Disease?

creutzfeldt — Sat, 17 May 2008 13:12:56 +0000

Oct. 25, 2006 — Viagra may ease blood pressure in the lungs of people with chronic obstructive pulmonary disease (COPD).

That’s according to a small Dutch study presented in Salt Lake City at Chest 2006, held by the American College of Chest Sildenafil citrate tadalafil cheap
.

COPD is the No. 4 cause of death in the U.S. and worldwide, according to the National Heart, Lung, and Blood Institute (NHLBI).

COPD is a lung disease in which breathing is difficult. It’s usually caused by smoking erectile dysfunction tabs
, but it can also be caused by other lung irritants.

The disease develops slowly and may take years to show symptoms, which include:

Cough
Sputum (mucus) production
Shortness of breath (especially with exercise)
WheezingWheezing
Chest tightness

Those symptoms may or may not indicate COPD, states the NHLBI’s web site.

Viagra Study

The Viagra study included 12 COPD patients, half of whom had high blood pressurehigh blood pressure in the pulmonary artery, which brings blood to the lungs. The development of pulmonary need prescription viagra
pulmonary hypertension is a complication of COPD, but not everyone with COPD will develop it.

The researchers included Erectile pill Holverda, MSc, of Erectile dysfunction tabs
University Medical Center.

They tracked the patients’ pulmonary artery blood pressure before and after taking Viagra.

Why Viagra? It relaxes (dilates) blood vessels, lowering blood pressure and helping blood to flow.

First, the patients rested. Then they pedaled a stationary bike for three minutes at a mild pace.

As expected, pulmonary artery blood pressure was higher during exercise, since the lungs were working harder.

Next, the patients took a Viagra pill, waited 45 minutes, and repeated the rest and exercise tests.

Their pulmonary artery blood pressure during exercise was lower after taking Viagra.

“These data suggest that during daily activities some COPD patients may benefit” from drugs that dilate blood vessels, the researchers write.

Erectile Dysfunction: Cialis, Viagra and Levitra to Treat ED

creutzfeldt — Fri, 16 May 2008 03:28:43 +0000

There are only three oral drugs approved by the FDA to treat erectile
ed meds
: Cialis, Levitra, and Viagra. All work by increasing the flow of
blood into the penis so that when a man is sexually stimulated, he can get an
erection.

What Are the Differences Between Cialis, Levitra, and Viagra?

Cialis, Levitra, and Viagra work by a similar mechanism to cause erections.
There are subtle differences in how long the drug works and how quickly it
works. Levitra works a little longer than Viagra. They both take effect in
about 30 minutes. With Levitra, the effects last for about 5 hours. With
Viagra, the effects last approximately 4 hours.

Cialis works a bit faster (within about 15 minutes), and the effects last
much longer — up to 36 hours in some cases.

If One of These Drugs Isn’t Effective for Erectile Dysfunction, Can I Try Another?

Yes, but because these drugs work the same way, it’s unlikely that you’ll
have success with one if you’ve failed to achieve an adequate erection with
another.

What Precautions Should I Take Before Taking One of These Drugs?

There are certain situations in which these drugs may not be safe to take.
Before taking them, tell your doctor:

If you are allergic to any drugs, including Viagra or other ED
medications.
About any cialis vs viagra
or nonprescription medications you are currently
taking, including herbal and dietary supplements.
If you are scheduled for surgery, including dental surgery.
If you take nitroglycerin or a long-acting nitrate to treat chest pain. The
combination of Cialis, Levitra or Viagra with these drugs can cause dangerously
low blood pressure.
If you take erectile dysfunction
for blood pressure or prostate problems. The
combination of Cialis or Levitra with these drugs can also cause dangerously
low blood pressure.

In addition, always follow the directions on your prescription label
carefully and ask your doctor or pharmacist to explain any part that you do not
understand. Take these drugs exactly as directed. Do not take more or less or
take it more often than prescribed by your doctor. Do not take these drugs more
than once a day.

Who Should Not Take Cialis, Levitra or Viagra?

If you have suffered from a heart attack, stroke or life threatening
arrhythmia (irregular heart rate) within the last 6 months you should discuss
other options with your doctor. It is also advised to avoid these drugs if you
have uncontrolled high or low blood pressure or if you experience chest pain
with sex.

What Are the Side Effects of Cialis, Levitra and Viagra?

Side effects are not common but they can occur. Side effects can
include:

Headache
Upset stomach or heartburn
Flushing (feeling warm)
Nasal congestion
Changes in vision (color, glare)
Back pain (with Cialis)

Call your doctor if you experience severe forms of these symptoms or if they
do not go away after 4-8 hours.

Warning

Call your doctor or seek emergency treatment immediately if you experience
any of the following symptoms:

Rash
Painful erection
Prolonged erection (longer than 4 hours)
Fainting
Chest pain
Itching or burning during urination

Stop taking these medications and call a doctor or health care provider
right away if you experience sudden or decreased vision loss in one or both
eyes. A rare vision problem called NAION has been reported by a few men using
these drugs. NAION (purchase cheap cialis online
anterior ischemic optic neuropathy) causes a
sudden loss of eyesight because blood flow is blocked to the optic nerve.
People who have a higher chance for NAION include those who:

Are over 50 years old
Smoke
Have heart disease
Have diabetes
Have high blood pressure
Have high cholesterol
Have certain eye problems

How Should These Drugs Be Stored?
