What is Viagra?

Viagra is a medication, obtainable by prescription only, to treat erectile dysfunction (ED). Erectile dysfunction means that a man’s penis is unable to harden during sexual excitement, or if a man cannot sustain an erection suitable for sexual intercourse.

Viagra does NOT increase sexual desire; protect against sexually transmitted diseases; or act as a form of contraception.

You should not take Viagra if:

• You use nitrates;
• Your doctor has advised you not to be sexually active;
• You use "leisure drugs" called "poppers".

What are the risks of using Viagra?

Viagra may cause blood pressure to suddenly drop to a dangerous level if used with some medications such as alpha blockers, nitrates and recreational drugs. If your blood pressure suddenly drops this can cause extreme dizziness and you may even have a heart attack or stroke.

In rare situations, Viagra may cause the medical condition known as priapism, meaning that an erection will not go down. Some men have reported unusual vision problems such as having difficulty in distinguishing the difference between blue and green colors.

When using Viagra you may experience some common side effects such as: diarrhea, urinary tract infection, blocked or runny nose, upset stomach, flushing, or headache.

There may be other side effects of Viagra which are not mentioned in this information guide. Be sure to tell your doctor immediately if you have any continual discomfort, or if you suspect you have had an allergic reaction to Viagra. An allergic reaction will present symptoms such as hives, swelling of your facial area, severe rash or itchiness, and difficulty in breathing.

Before you use Viagra, tell your doctor if:

• You are taking alpha blockers to treat a prostate problem or high blood pressure;
• You are taking drugs to treat HIV;
• You have multiple myeloma, leukemia, or sickle cell anemia;
• You have ever had priapism (prolonged erection);
• You have a penis disorder such as Peyronie’s disease;
• You have a bleeding disorder;
• You have a stomach ulcer;
• You have retinitis pigmentosa;
• You have kidney problems, or if you undergo dialysis treatment;
• You have suffered severe eye problems;
• You have liver problems;
• You have had a stroke;
• You have uncontrolled high or low blood pressure;
• You have had any heart problems.

Can other medications be taken with Viagra?

Provide your doctor with a full list of any prescription or non-prescription medicines that you take regularly. This list should also include herbal and vitamin supplements. Your doctor will decide if any of these should not be used with Viagra.

Very important information

If you have used Viagra and you lose your eyesight, you must urgently get medical assistance. This loss of eyesight (in one eye or both) is known as NAION (non-arteritic anterior ischemic optic neuropathy) which is caused when the blood cannot flow into the optic nerve.

It has not been established if NAION is linked to the use of Viagra. However, this condition is more likely to affect men who:

• Have existing eye problems;
• Have heart disease;
• Smoke;
• Are older than 50 years;
• Have high blood pressure;
• Have diabetes.
