| Viagra
tablets are for oral use. Swallow the tablet whole with
water. You may take Viagra with or without food or alcohol.
Side Effects
Tell
your doctor or health care professional as soon as possible
if you do not feel well while you are taking Viagra. Viagra
helps most people with erectile dysfunction, but it may
have unwanted side effects in a few people. Most of the
side effects are mild to moderate in nature. Do not be alarmed
by the following list of the most common possible side effects.
You may not experience any of them. Ask your doctor or health
care professional to answer any questions you may have.
Tell your doctor or health care professional if you notice
any of the following and they are troublesome, severe, or
do not go away: headache; indigestion; back pain; muscle
aches; nasal congestion; facial flushing; swelling of the
eyelids; eye pain; conjunctival hyperaemia (red eyes); dizziness.
Allergic reactions to Viagra (including skin rashes) could
occur. In rare instances it is possible that a prolonged
and possibly painful erection may occur after taking Viagra.
If you have such an erection which lasts continuously for
more than 4 hours, you should contact a doctor immediately.
In case of chest pain occurring during or after sexual activity
you should NOT use nitrates but you should seek immediate
medical assistance. Tell your doctor or pharmacist if you
notice anything that is making you feel unwell.
Precautions
Do
not take Viagra
if you are currently taking any nitrates or amyl nitrite.
Nitrates are medicines used in the treatment of angina pectoris
("chest pain"). Viagra
has been shown to increase the effects of these drugs. If
you are taking any form of nitrate or are unsure tell your
doctor. Do not take Viagra
if you have had an allergic reaction in the past to sildenafil
citrate or any of the other ingredients of Viagra.
Some of the symptoms of an allergic reaction to Viagra
may include shortness of breath, wheezing or difficulty
breathing; swelling of the face, lips, tongue or other parts
of the body; rash, itching or hives on the skin. Do not
take Viagra
after the expiration date printed on the pack or if the
packaging is torn or shows signs of tampering. If you are
not sure whether you should start taking Viagra,
talk to your doctor. Before you start to take Viagra,
tell your doctor if you have allergies to any other medicines,
foods, preservatives or dyes. Viagra
is not intended for use by women or by children under the
age of 18 years. No special consideration is needed for
the elderly or people with diabetes.
Drug Interactions
Tell
your doctor or pharmacist if you are taking any other medicines,
including any that you get without a prescription from your
pharmacy, supermarket or health food shop. Some medicines
and Viagra
may interfere with each other. This is particularly important
if you are treated with: nitrates (used to treat heart conditions);
rifampicin (an antibacterial product used amongst others
against tuberculosis); ketoconazole or itraconazole (used
against fungal infections) erythromycin (an antibacterial
product); protease inhibitors (HIV treatments). You may
need different amounts of your medicines or you may need
to use different medicines. You should not take Viagra
together with any other treatments for erectile dysfunction.
Your doctor and pharmacist have more information on medicines
to be careful with or avoid while taking Viagra.
Storage
Store Viagra at room temperature between
59 and 86 degrees F (15-30 degrees C) away from light and
moisture. Keep Viagra and all medications out of the reach
of children.
Notes
Do not share Viagra with others, since they
may have a problem that is not effectively treated by this
drug. Use of Viagra does not protect against STD's (e.g.,
HIV, Hepatitis B, gonorrhea).
