Follow all directions on your prescription label and read all medication guides or instruction sheets. Use sildenafil exactly as directed. The brand sildenafil known as Viagra should be taken 30-60 minutes before sexual activity. It’s important to take it without a meal because fat in a meal can decrease and delay its absorption, which can lower sildenafil’s effectiveness. You may take it up to four hours before sexual activity. Do not take Viagra more than once per day. Revatio is usually taken three times each day, about four to six hours apart. If you are taking the oral suspension (liquid), shake well before you measure a dose. If you miss a dose of Revatio, take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time. Store at room temperature away from moisture and heat.

How long does sildenafil take to work?

Sildenafil (Viagra) is a short acting medication with a rapid onset. It reaches peak blood levels in 60 minutes on average. However, consuming a fatty meal immediately prior to taking Viagra can slow absorption and effectiveness.

Viagra can help you have an erection when sexual stimulation occurs. An erection will not occur just by taking a pill.

How long does sildenafil last?

Sildenafil is a short acting drug and usually lasts 4–5 hours but this does not mean you will maintain an erection for this long.

The time that it takes to eliminate sildenafil may be prolonged in older people and people with liver or kidney disease.
