Suhagra 100 mg Tablet is used to treat erectile dysfunction (ED) in men. It increases blood flow to the penis, helping you get and maintain an erection. It works by relaxing the blood vessels in the penis, so more blood flows in when you’re sexually aroused. You can take Suhagra 100 mg with or without food. It's best to take it about 1 hour before sexual activity. It usually takes between 30 to 60 minutes to start working. This medicine only works if you are sexually stimulated and should not be taken if you do not have ED.
