GENERIC AVAILABLE: No.
PREPARATIONS: Tablets: 50, 100 and 200 mg.
STORAGE: Avanafil should be stored at room temperature between 20 C and 25 C (68 F and 77 F).
DOSING: For most individuals, the recommended starting dose of avanafil is 100 mg per day taken about 30 minutes before sexual activity. Depending on the adequacy of the response or side effects, the dose may be increased to 200 mg or decreased to 50 mg a day. Individuals who are taking medications that moderately increase the blood levels of avanafil should not exceed a total dose of 50 mg in 24 hours (See drug interactions).
DRUG INTERACTIONS: The breakdown and elimination of avanafil from the body may be decreased by several drugs, leading to increased blood levels of avanafil and possible toxicity. Ketoconazole (Nizoral), itraconazole (Sporanox), indinavir (Crixivan) and ritonavir (Norvir), atazanavir (Reyataz), clarithromycin (Biaxin), nelfinavir (Viracept), saquinavir (Invirase), telithromycin (Ketek) profoundly increase blood levels of avanafil and should not be combined with avanafil.
