Important Safety Information. STENDRA™ (avanafil) is prescribed to treat erectile dysfunction (ED).

If you experience chest pain, nausea, or any other discomforts during sex, seek immediate medical help. STENDRA may affect the way other medicines work. Tell your healthcare provider if you take any of the following; medicines called HIV protease inhibitors, such as ritonavir (Norvir®), indinavir (Crixivan®), saquinavir (Fortavase® or Invirase®) or atazanavir (Reyataz®); some types of oral antifungal medicines, such as ketoconazole (Nizoral®), and itraconazole (Sporanox®); or some types of antibiotics, such as clarithromycin (Biaxin®), telithromycin (Ketek®), or erythromycin. In the rare event of an erection lasting more than 4 hours, seek immediate medical help to avoid long-term injury.
