Never take avanafil with nitrates, nitric-oxide donors, riociguat, or another erectile-dysfunction medicine. Strong CYP3A4 inhibitors are also contraindicated; some moderate inhibitors require no more than 100 mg every 48 hours.

Review the response pattern
After several correctly timed attempts, review efficacy and effects. Do not repeat the dose on the same day or move to 200 mg without approval.
Bijwerkingen
Common effects
Headache, flushing, and nasal congestion are common. Dizziness, back pain, indigestion, or visual symptoms can also occur.
Blood-pressure effects
Avanafil can lower blood pressure, especially with alpha-blockers, other blood-pressure medicines, or substantial alcohol. Sit or lie down if light-headed and seek advice for fainting.

Wat te verwachten
Avanafil is designed for on-demand use and may act within the prescribed pre-sex window, but timing is not a guarantee of response. It requires stimulation and does not address every cause of erectile dysfunction. Review several correctly used doses with the doctor.
