Penegra 50 mg Tablet is used to treat erectile dysfunction (ED) in men. It helps increase blood flow to the penis, making it easier to get and maintain an erection. It works by relaxing the blood vessels in the penis, so more blood can flow in when you are sexually aroused. You can take Penegra 50 mg Tablet with or without food. It's best to take it about 1 hour before sexual activity. It usually starts working within 30 to 60 minutes. This medicine only works when you're sexually stimulated and should not be taken if you do not have ED.
