What is gonorhea? if you have this, how to cure it?

If you have it, then you must have seen a doctor for the diagnosis and know that it's an STD. Only your doctor can tell you what antibiotic you need to be on and the proper dosage. No one here can tell you that. If they try to, don't listen. They are not your doctor and don't know a thing about your medical health to know what's safe for you.
