In most cases, doctors recommend taking the recommended dose of Fildena 100 mg one hour before planned sexual activity. On the other hand, if patients wish to take Fildena 100 milligrams later, they can do so anywhere, but they should take it 30 minutes to 4 hours before having sexual contact with a partner. You can only take one 100 milligram Fildena tablet at a time. This pill can be taken without swallowing or with food.Absorption is enhanced when taken with a high-fat meal.
