Levitra is a prescription medication used to treat erectile dysfunction (ED) in men. Its active ingredient, vardenafil, works by increasing blood flow to the penis, helping to achieve and maintain an erection when sexually aroused. Levitra is typically taken about 30 minutes before sexual activity and can last for up to 5 hours. Like other ED medications, Levitra may have side effects, including headaches, flushing, and nasal congestion. It is important to consult a healthcare provider before using Levitra, especially for individuals with certain health conditions or those taking other medications, to ensure it is safe and appropriate for their situation.
