Norfloxacin may cause swelling or tearing of a tendon (the fiber that connects bones to muscles in the body), especially in the Achilles' tendon of the heel. These effects may be more likely to occur if you are over 60, if you take steroid medication, or if you have had a kidney, heart, or lung transplant. Stop taking norfloxacin and call your doctor at once if you have sudden pain, swelling, tenderness, stiffness, or movement problems in any of your joints. Rest the joint until you receive medical care or instructions.

If you are being treated for gonorrhea, your doctor may also have you tested for syphilis, another sexually transmitted disease.
