Use Sildenafil (Viagra) exactly as prescribed by your doctor. Under no circumstance should you take more than recommended. By doing so, you increase your chances of side effects. Read the patient instructions in detail that come with your prescription of Sildenafil (Viagra).

If you're prescribed the oral liquid form of Sildenafil (Viagra), it's important that you shake the bottle well before use (roughly 10 seconds). Don't forget to rinse the oral syringe used to administer your dose after each use.

Dosing

Your doctor prescribes a specific dose tailored to your needs. Be sure to follow their directions for when to take Sildenafil (Viagra) and how often.

Your prescription varies based on the strength of your dose, how much you may take in a day, and how often you may take it.

Below is an example dose:

Sildenafil (Viagra) is usually taken when needed, 30 minutes to an hour before sexual activity. You may take it up to 4 hours before sexual activity.

Sildenafil (Viagra) is part of a group of drugs called phosphodiesterase type 5 (PDE5) inhibitors that increases levels of cGMP. This relaxes smooth muscle in the blood vessels, increasing blood flow to the penis and allowing for stronger, more consistent erections.

Sildenafil Mechanism of Action

When a man is aroused, their nerves send chemical signals to the blood vessels in their penis. Blood vessels in the penis open up which allow blood to fill them.

At the same time, veins close. Pressure then traps the blood within the Corpora Cavernosa. This causes the penis to expand and become erect.

When a man has erectile dysfunction, the blood vessels are failing to open up properly. Sildenafil (Viagra) works by relaxing the muscles of the blood vessels and increases blood flow to the penis, causing the penis to become erect.

Sometimes an enzyme called phosphodiesterase type-5 acts too quickly. This causes a man's erection to become difficult to sustain. Sildenafil (Viagra) helps control this enzyme to help maintain an erection.
