Suhagra 25 mg Tablet is used to treat erectile dysfunction (ED) in men. It works by increasing blood flow to the penis, helping men get and maintain an erection. It relaxes the blood vessels so more blood can flow in when you're sexually aroused. You can take Suhagra 25 mg 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 will only help produce an erection if you’re sexually stimulated, and it should not be taken if you don’t have ED.
