A first dose is 10 mg at least 30 minutes before sexual activity. Dosage can then be adjusted depending on how the individual responds. The maximum is 20 mg as a single dose.
The patient should take no more than one dose in 24 hours, but a daily dose of 10 mg to 20 mg is not recommended. This is because a portion of the drug remains in the system for at least 24 hours.
Patients who expect to be sexually active at least twice a week can take a daily dose of 5 mg, and this may be reduced to 2.5 mg once daily, depending on the individual reaction.
