Viagra (Sildenafil Citrate)

Viagra F.A.Q.

Frequently Asked Questions About Viagra

This list of frequently asked questions and answers on viagra has been
developed from various sources, primarily: the Food and Drug
Administration, CDER's Drug Information Branch and Arnot Ogden Medical
Center.

1. What is viagra for?
Viagra is approved for the treatment of men who have difficulty having
and maintaining an erection (erectile dysfunction or impotence).

2. Is viagra available to pharmacies?
Viagra is available to most online and offline pharmacies. The
decision of availability is completely up to the company marketing the
product, Pfizer, Inc. For further information contact your pharmacist
or Pfizer, Inc. directly.

There are many counterfeit products claiming to be viagra that don't
work. Real viagra is a blue pill that has 'pfizer' on the front and
'vgr' followed by the pill strength in milligrams on the back.

To see images, for an idea of what real brand name viagra looks like,
see this. The only thing that works exactly like viagra, is sildenafil
citrate (viagra without the brand name, otherwise known as generic
viagra). For more information, see this.

3. How much does viagra cost?
The FDA has no input into or legal control over the pricing of any
drug product. Some companies sell viagra far above what most others
charge.

The more you buy, the less the cost per does will be. If you have
tried viagra and know it works for you, buying in larger quantities is
recommended. If you have never used viagra, you should get a smaller
quantity to see if it works for you.

4. Does insurance cover the cost of viagra?
The FDA has no input into or legal control over whether an insurance
company does or does not cover the cost of drugs. Some insurance plans
do cover viagra, others don't. Please call you insurance company if
you have questions about whether your particular insurance provider
will cover the cost of this product for you.

5. How does viagra work?
An erection is the result of an increase in blood flow into certain
internal areas of the penis. Viagra and other PDE5 inhibitors (like
cialis and levitra) work by enhancing the effects of one of the
chemicals the body normally releases into the penis during sexual
arousal. This allows an increase of blood flow into the penis.

6. How do I take viagra?
Viagra is taken orally (maximum once per twenty-four hour period)
about one hour before sexual activity. For more detailed information
consult with your health care provider.

7. How long does it take for viagra to be effective?
When consumed orally on an empty stomach, maximum observed plasma
concentrations are reached within 30 to 120 minutes (60 minutes is
average for the maximum level to be seen in the blood stream).

The effects of viagra can last up to 4 hours, but the response at 4
hours is less than it was 2 hours after consumption. When viagra is
taken with a high fat meal, the rate of effectiveness is reduced.

If a longer lasting medication is required, cialis should be
considered. It works in the same way as viagra (it is a PDE5
inhibitor), but the effects of cialis have been shown to last 24 to 36
hours in a majority of users.

8. How is viagra supplied?
Viagra is available as oral tablets in 25mg, 50mg and 100mg strengths.
50mg is the recommended dose size. If you are paying for medication
yourself, you should always buy the 100mg size and split the pill into
50mg doses. This is because 50mg and 100mg pills usually cost about
the same amount of money.

Some people don't like splitting pills because they worry that the
viagra might not be evenly distributed in both halves. Splitting pills
has not been a known problem, but you may choose to buy 50 milligram
pills if splitting pills is not what you want to do.

Be aware that buying 50mg pills will almost twice as expensive as
buying 100mg pills and splitting them yourself. Viagra, a film-coated
tablet, should be stored in a cool, dry place. There are reports of
people leaving viagra in their vehicles, only to return to find the
tablets melted together.

9. Is viagra available over the counter?
No, viagra is available by prescription only.

9a. How can I get a prescription?

You can make an appointment to visit your doctor and explain your
 condition. This can be awkward for some people, but there is
 nothing to be ashamed of. Your doctor has heard it before,
 millions of men are impotent.

Online, you can compare prices here. All pharmacies sell genuine
 viagra made by Pfizer. No previous prescription required, a doctor
 will write one after you fill out an online medical questionnaire.

10. Are there any side effects with viagra?
Viagra is extremely safe and offers very few side effects. As with any
drug product, there are side effects of the product in some people.
The most commonly reported are: headache, flushing, stomach ache,
urinary tract infection, diarrhea, dizziness, rash, and mild and
temporary visual changes (color perception changes, light perception
changes, and blurred vision). Stomach ache and abnormal vision were
more common at 100 mg than at lower doses.

Although more rare, the following may occur: increased intraocular
pressure (fluid pressure inside the eye), myocardial infarction (heart
attack), priapism (a painful medical condition where an erect penis
stays erect without stimulation for more than 4 hours), severe
hypotension (abnormally low blood pressure), stroke, sudden hearing
loss, and ventricular arrhythmias (fast heart rhythm).

11. Is it true that 69 Americans taking the impotence pill viagra
died?
From the marketing of viagra in late March 1998 through July 1998
(during which more than 3.6 million outpatient prescriptions were
dispensed) the FDA received reports of 123 patients who died after
having been prescribed this drug. Twelve deaths concerned foreign
patients and 30 concerned patients with unverifiable information (from
hearsay, rumor, the media, or unidentifiable reporters).

In addition, reporters stated that they did not know if the drug had
been used for 12, leaving 69 U.S. patients who died after having taken
viagra. Of these, cause of death was unmentioned or unknown for 21,
two patients had strokes, and 46 had cardiovascular events (21 with
definite or suspected myocardial infarction, 17 with cardiac arrest, 4
with cardiac symptoms, 3 with coronary artery disease, and one with
severe hypotension leading to cardiac arrest).

12. Can viagra be used with other treatment for impotence?
The safety and effectiveness of viagra when used with other treatment
for impotence has not been studied. The use of such treatments in
combination with viagra is not recommended at present.

13. What if I am taking other drugs?
Since viagra does lower blood pressure somewhat, those taking nitrates
such as nitroglycerine (which also reduces blood pressure) shouldn't
take viagra simultaneously. It may lead to fainting. Also, talk to
your doctor if you're taking antibiotics or antifungal drugs, like
ketoconazole, before taking viagra.

At present, viagra is not recommended for people taking commonly
prescribed short/long acting nitrates because the combination may
lower blood pressure. A list of commonly prescribed short/long acting
nitrates available in the United States:

names, including poppers.)
e.g., butyl nitrate

14. What types of psychoactive drugs are safe to use in combination
with viagra?
This list is by no means complete, but here are some chemicals that
have shown no negative side effects when consumed with viagra (or
other PDE5 inhibitors like cialis and levitra).

Barbiturates (sleeping pills)
Benzodiazepines (tranquilizers)
Brugmansia (Brugmansia spp.)
Calamus (Acorus calamus)
Catnip (Nepeta cataria)
Chloral Hydrate
Hashish (and hashish oil)

Passion Flower (Passiflora incarnata)
PCP
Psychoactive Mushrooms

Wormwood (Artemisia absinthium)

This list is by no means complete, but here are some chemicals that
may increase heart rate and have negative side effects if they are
consumed (with viagra) by people with heart problems.

The reason for this is because sexual activity also increases heart
rate. Although nearly everyone who takes the following chemicals in
conjunction with viagra will be ok, people with heart problems may
experience negative consequences.

Acid (LSD)
Amphetamines (ice, speed, meth, etcetera)
Ayahuasca
