Important safety warning
Do not take PDE5 inhibitors if you use nitrates (e.g., nitroglycerin, isosorbide) for chest pain — the combination can cause a sudden, dangerous drop in blood pressure. Stop use and seek emergency care for an erection lasting more than 4 hours, sudden vision or hearing loss, or chest pain. Inform your provider of all medications, including alpha-blockers, antihypertensives, and other PDE5 inhibitors. See full safety information.
No charge until a provider prescribes. Prescription required.
