Suhagra is equally effective whether taken before or after a meal. Since it often takes Suhagra 30-60 minutes to kick in, you should take it approximately an hour before you expect to have sex. You shouldn't take Suhagra more than once per 24 hours. Suhagra's suggested beginning dose is 50 mg, however the amount can be adjusted up to 100 mg or down to 25 mg according on how well it works and how well it is tolerated.
You need to be sexually aroused in order for Suhagra to help you obtain an erection.
