Vitaros is a prescription medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient alprostadil, which belongs to a class of drugs known as vasodilators. Vitaros is unique because it is applied topically as a cream directly to the penis, offering an alternative for those who may not be able to take oral ED medications. Upon application, alprostadil works by expanding blood vessels and increasing blood flow to the penis, helping to achieve and maintain an erection. Vitaros begins to work within 5 to 30 minutes of application and its effects can last for up to 1-2 hours. It is important for users to follow their healthcare provider's instructions closely when using Vitaros to ensure safety and effectiveness.
