Viagra 25 mg/50 mg/100 mg Film-Coated Tablets

• VIAGRA belongs to a group of medicines called phosphodiesterase type 5 inhibitors.

• VIAGRA is used to treat erectile dysfunction, sometimes known as impotence, in men. This is when a man cannot get, or keep, a hard, erect penis suitable for sexual activity.

• VIAGRA works by relaxing the blood vessels in your penis when you are sexually excited. This allows blood to flow into your penis, allowing you to get an erection in the natural way.

• VIAGRA will work only if you are sexually excited.

• VIAGRA will not increase your sex drive.

• VIAGRA is not for use in women.

Do not take VIAGRA

• If you are hypersensitive (allergic) to sildenafil or any of the other ingredients of VIAGRA (listed in section 6).

• If you are being treated for angina (chest pain) or other heart conditions with certain medicines called nitrates.

• If you have loss of vision in one eye because of non-arteritic anterior ischaemic optic neuropathy (NAION), a medical condition involving loss of vision due to damage to the optic nerve from insufficient blood supply.

• If you are using ketoconazole or itraconazole (used to treat fungal infections), erythromycin, ritonavir or saquinavir (used to treat HIV infections) or riociguat (used to treat pulmonary hypertension).

• If you have a severe liver or kidney problem.

Warnings and precautions

Take special care with VIAGRA:

VIAGRA offers no protection against sexually transmitted diseases. You should use protection measures necessary to guard against sexually transmitted diseases, including the human immunodeficiency virus (HIV/AIDS). Please tell your doctor:

• If you have problems with your heart. Your doctor should in that case carefully check whether your heart can take the additional strain of having sex.

• If you have previously been advised against sexual activity.

• If you have previously had sudden loss of eyesight in one or both eyes.

• If you have an eye condition known as “crowded disc”.

• If you are over 50 years of age.

Other medicines and VIAGRA

Always tell your health care provider if you are taking any other medicine. (This includes all complementary or traditional medicines).

• You should not take VIAGRA if you are taking medicines called nitrates as the combination of these medicines may cause a potentially dangerous decrease in your blood pressure. Always tell your doctor or pharmacist if you are taking any of these medicines that are often used for the treatment of angina pectoris or “chest pain”.

• You should not take VIAGRA with cimetidine (medicine used to treat stomach ulcers) or erythromycin (an antibiotic) as they increase the blood levels of VIAGRA.

Do not share medicines prescribed for you with any other person.

Always take VIAGRA exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

The usual dose is 50 mg, taken about one hour before sexual activity. This dose may be increased to 100 mg or decreased to 25 mg by your doctor. Swallow the film-coated 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 high fat containing 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

In the event of overdosage, consult your doctor or pharmacist. If neither is available contact the nearest hospital or poison centre.

Taking a dose higher than 100 mg does not increase the effect of VIAGRA. 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.

VIAGRA can have side effects. Not all side effects reported for VIAGRA are included in this leaflet. Should your general health worsen or if you experience any untoward effects while taking VIAGRA, please consult your health care provider for advice.

If any of the following happens, stop taking VIAGRA and tell your doctor immediately or go to the casualty department at your nearest hospital:

• If you experience a prolonged and painful erection which lasts continuously for more than 4 hours.

• If you experience chest pains at the start of or during sexual intercourse.
