Before you use Viagra, you should inform your doctor if you have been using any of the following medicines:

amlodipine (Norvasc)
medications for high blood pressure
cimetidine (Tagamet, Tagamet HB),
erythromycin,
isosorbide (Imdur, Ismo, Isordil, and others),
itraconazole (Sporanox), ketoconazole (Nizoral),
nitroglycerin (Nitro-Bid, Nitrostat, and others),
medications to treat impotence,
phenobarbital,
rifampin (Rifadin, Rimactane),
ritonavir (Norvir),
saquinavir (Invirase),
vitamins.

Dosage:

The usual dosage to start at is 50-100 mg. This is for individuals anywhere between the ages of 18-65. Older individuals and others taking various forms of drugs are given lower doses (25mg). This is because of the reduced elimination of Viagra from their bodies.

Viagra may be consumed wit or without food. When it is taken with foods, it will probably take a little longer for it to act. This is especially the case with consuming fatty foods; it is known that Viagra certainly does take longer to act when consumed with fatty foods.

In order to consume Viagra, the tablets may be taken as a whole piece or even crushed. Viagra is taken once a day, and if one wishes to consume it on a daily basis a physician should be consulted.

The best time to take Viagra is about an hour before sexual intercourse. However, it may even be taken half an hour before. On consuming Viagra, blood flow in the erectile tissue increases and blood retention within it decreases, resulting in an accumulation of blood that makes the erection possible. However, for this to take place, you need to be sexually stimulated. Without sexual stimulation, nothing will happen. When you have stimulation, the effects of Viagra will last for around four hours.
