Viagra is an oral treatment for impotence. It improves the flow of blood into the penis which allows impotent men to get a strong erection during sexual intercourse.
Who should take Viagra?
Viagra is a preion medicine which can be used by men suffering from erectile dysfunction. If you are unable to get an erection despite being sexually aroused due to physical or psychological factors, then you can use Viagra after consulting your physician.
Taking Viagra & the right dosage
Viagra takes 30 minutes to an hour to work. So, it is recommended that you take your dose at least one hour before you wish to have sex.
You can have Viagra before or after a meal.
Viagra is usually available in a wide range of dosages like 25mg, 50mg and 100mg.
50mg is the ideal starting dose for most men. However, if you are above the age of 60 or have some medical conditions, then you may want to start with a lower dosage of 25mg.
If you have received the 100mg dosage pill, then you can use a pill splitter to split the pill into 4 pieces and use the lowest dose of 25mg.
You should strictly use only the prescribed dosage in a 24 hour period. Any extra dose may lead to severe health complications.
Storage
Store Viagra in a cool and dark place at room temperature. Do not store it in a place where it can get exposed to direct sunlight or moisture.
Keep it away from children and pets.
