How to use
Vardenafil is taken orally, with or without food, 30-60 minutes before sexual activity. It should not be taken more often than once every 24 hours. This medication can help achieve an erection when sexual stimulation occurs. An erection will not occur just by taking a pill.

Overdose
If you suspect an overdose of Vardenafil, seek emergency medical attention or contact your local poison control center. Overdose symptoms may include back pain, muscle pain, or vision problems.

Missed dose
Vardenafil is only taken when needed, so you are unlikely to miss a dose.

Notes
Do not share Vardenafil with others, since they may have a problem that is not effectively treated by this drug. Use of this drug does not protect against sexually transmitted diseases (e.g. HIV, Hepatitis B, Gonorrhea, Syphilis).
