Uses
Viagra works by improving a man's response to sexual stimulation,
increases blood flow to the penis, and allows him to lead
a normal sex life.
How to Take
Viagra 100mg is taken by mouth as needed. Viagra can work
in as quickly as 30 minutes and works for at least 4 hours.
Possible Side Effects
As with most prescription medications, Viagra may produce
the following side effects: headache, flushing, stomach upset,
nasal stuffiness, diarrhea and dizziness might occur.
Precautions
Only your doctor can decide if VIAGRA is right for you. VIAGRA
can cause mild, temporary lowering of your blood pressure.
You will need to have a thorough medical exam to diagnose
your erectile
dysfunction and to find out if you can safely take VIAGRA
alone or with your other medicines. Your doctor should determine
if your heart is healthy enough to handle the extra strain
of having sex.
Be sure to tell your doctor if you:
- Have ever had any heart problems (e.g., angina, chest pain, heart failure, irregular heart beats, heart attack or narrowing of the aortic valve)
- Have ever had a stroke
- Have low or high blood pressure
- Have a rare inherited eye disease called retinitis pigmentosa
- Have ever had any kidney problems
- Have ever had any liver problems
- Have ever had any blood problems, including sickle
cell anemia or leukemia
- Are allergic to sildenafil or any of the other ingredients of VIAGRA tablets
- Have a deformed penis, Peyronie's disease, or ever had an erection that lasted more than 4 hours
- Have stomach ulcers or any types of bleeding problems
- Are taking any other medicines

Tell your online doctor of all nonprescription and prescription
medication you may use, especially any nitrate medications
(e.g., nitroglycerin, isosorbide dinitrate), nitroprusside
(any "nitric oxide donor" medicines), cimetidine, erythromycin,
azole antifungals (e.g., itraconazole, ketoconazole), mibefradil,
