3. HOW TO TAKE VIAGRA
Always take VIAGRA exactly as your doctor
has told you. You should check with your doctor or pharmacist if you are not sure. The usual dose is 50 mg.
You should take VIAGRA about one hour
before sexual activity. Swallow the tablet whole with some water.
If you have the impression that the
effect of VIAGRA is too strong or too weak, talk to your doctor or pharmacist.
VIAGRA will only help you to get an
erection if you are sexually stimulated. The amount of time VIAGRA takes to work varies
from person to person, but it normally takes between half an hour and one hour.
You may find that VIAGRA takes longer to work if you take it with a heavy meal.
Drinking alcohol can temporarily impair
the ability to get an erection. To get the maximum benefit from your medicine,
you are advised not to drink large amounts of alcohol before taking VIAGRA.
If VIAGRA does not help you to get an erection,
or if your erection does not last long enough for you to complete sexual intercourse you should tell your doctor.
You should not use VIAGRA more than once a day.
If you take more VIAGRA than you should:
A dose above 100 mg does not increase the efficacy.
However, it will result in an increase in undesirable effects and their severity.
You should not take more tablets than your doctor tells you to.
Contact your doctor if you take more tablets than you should.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
4. POSSIBLE SIDE EFFECTS
Like all medicines, VIAGRA can cause side
effects although not everybody gets them. These effects are normally mild to moderate.
In controlled clinical trials the most
common side effects were headache or facial flushing and less commonly indigestion, dizziness,
stuffy nose, pounding heartbeat, or effects on vision (including colour tinge to vision,
increased brightness of light or blurred vision).
Since its introduction on the market,
the following events have been reported in men taking VIAGRA: vomiting, allergic reactions,
skin rash, bloodshot eyes, eye pain, rapid heartbeat or nosebleed. Partial, sudden, temporary,
or permanent decrease or loss of vision in one or both eyes have been reported.
Prolonged and sometimes painful erections have been reported after taking VIAGRA.
If you have such an erection which lasts continuously for more than 4 hours, you should contact a doctor immediately.
Also, the following events have been reported:
high blood pressure, low blood pressure, fainting, stroke, irregular heartbeat, chest pain,
sudden death, heart attack or temporary decreased blood flow to parts of the brain.
Most, but not all, of these men had heart
problems before taking this medicine. It is not possible to determine whether these
events were directly related to VIAGRA. If you have chest pains during or after intercourse
you should not use nitrates but you should contact your doctor immediately.
Muscle aches can occur if VIAGRA is taken more frequently than once a day.
If any of the side effects get serious, or if you notice any side effects not listed in this leaflet please tell your doctor.
