Avana 100 mg is a prescription medication commonly associated with avanafil, an active ingredient used to treat erectile dysfunction (ED) in adult men. Erectile dysfunction is a condition in which a man has difficulty achieving or maintaining an erection suitable for sexual activity.

Avanafil belongs to a class of medicines called phosphodiesterase type 5 (PDE5) inhibitors. It works by helping relax blood vessels and increasing blood flow to the penis during sexual stimulation. This may help men achieve and maintain an erection when sexually aroused. The medicine does not increase sexual desire and does not cause an erection automatically without sexual stimulation.

Avana 100 mg is generally taken before planned sexual activity, according to a doctor's instructions. The timing and suitability of the dose depend on individual health conditions, other medications, and treatment needs.

Common side effects may include headache, facial flushing, nasal congestion, dizziness, and indigestion. Avanafil must not be combined with nitrate medications, such as nitroglycerin, because the combination can cause a dangerous drop in blood pressure. Medical advice is especially important for people with heart conditions or those taking medicines that affect blood pressure.
