What special precautions should I take?

Before taking avanafil,

  • If you are allergic to avanafil spedra 50 mg, any other medications, or any of the ingredients in avanafil tablets, tell your doctor and pharmacist. Consult your pharmacist or patient information for a list of the ingredients.
  • If you are taking or have recently taken riociguat (Adempas) or nitrates such as isosorbide dinitrate (Dilatrate-SR, Isordil, in BiDil), isosorbide mononitrate (Monoket), or nitroglycerin, do not take avanafil (Minitran, Nitro-Dur, Nitromist, Nitrostat, or others). Nitrates are available in the form of tablets, sublingual (under the tongue) tablets, sprays, patches, pastes, and ointments. If you are unsure whether any of your medications contain nitrates, consult your doctor.
  • While taking avanafil, avoid using nitrate-containing street drugs such as amyl nitrate and butyl nitrate ('poppers').
  • Inform your doctor and pharmacist about any other prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are currently taking or intend to take. Make sure to include any of the following: alpha blockers Other erectile dysfunction medications or treatments; hypertension medications; nefazodone (Ketek). Your doctor may need to adjust the doses of your medications or closely monitor you for side effects. Many other medications may interact with avanafil, so be sure to inform your doctor about all medications you are taking, including those not on this list.
  • Tell your doctor if you've ever been told by a doctor to avoid sexual activity for medical reasons, if you've had heart surgery in the last 6 months, or if you've ever had an erection that lasted more than 4 hours. Tell your doctor if you have or have ever had angulation, cavernosal fibrosis, or Peyronie's disease; a heart attack; a stroke; an irregular heartbeat; a blocked artery; angina (chest pain); high or low blood pressure; heart failure; or blood cell problems such as sickle cell anaemia (a disease of the red blood cells); ulcers; bleeding problems; or liver or kidney disease.
