Avanafil Stendra is a prescription medication used to treat erectile dysfunction (ED) in men. Avanafil is the active ingredient in Stendra, and it belongs to a class of medications called phosphodiesterase type 5 (PDE-5) inhibitors. These medications work by relaxing the muscles of the penis, allowing for increased blood flow to the area and resulting in an erection. Avanafil works by inhibiting the action of PDE-5, an enzyme in the body that breaks down a substance called cyclic guanosine monophosphate (cGMP). cGMP is responsible for relaxing the muscles of the penis, which is necessary for increased blood flow. By inhibiting PDE-5, Avanafil allows for an increase in cGMP levels, resulting in an erection. Avanafil is taken orally as a tablet, usually 30 minutes before sexual activity. It is important to note that alcohol may decrease the effectiveness of Avanafil and should be avoided while taking the medication. The most common side effects of Avanafil include headache, flushing, stomach upset, nasal congestion, and dizziness. Less common side effects include muscle aches, back pain, vision disturbances, and an erection that lasts longer than 4 hours. If any of these side effects occur, it is important to speak with a healthcare provider right away. Avanafil is an effective treatment for ED, but it is important to note that it does not protect against sexually transmitted diseases (STDs). It is recommended that people engaging in sexual activity use a condom in order to protect themselves from STDs. Avanafil is not recommended for use in women or children. It is also not recommended for people with certain medical conditions, such as heart disease, high or low blood pressure, or kidney or liver disease. It is important to speak with a healthcare provider before taking Avanafil to ensure it is safe for use.
