It is very important that your doctor check your or your child's progress while receiving this medicine. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to receive it. Blood and urine tests may be needed to check for unwanted effects.
Levofloxacin may rarely cause inflammation (tendinitis) or tearing of a tendon (the cord that attaches muscles to the bones). This can occur while you are receiving the medicine or after your last dose. The risk of having tendon problems may be increased if you are over 60 years of age, are using steroid medicines (eg, dexamethasone, prednisolone, prednisone, or Medrol®), have severe kidney problems, have a history of tendon problems (eg, rheumatoid arthritis), or have received an organ (eg, heart, kidney, or lung) transplant. Check with your doctor right away if you have sudden pain or swelling in a tendon after exercise (eg, ankle, back of the knee or leg, shoulder, elbow, or wrist), bruise more easily after an injury, or are unable to bear weight or move the affected area. Refrain from exercise until your doctor says otherwise.
This medicine may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and require immediate medical attention. Tell your doctor or nurse right away if you have a rash, itching, hives, hoarseness, lightheadedness or fainting, trouble breathing or swallowing, or any swelling of your hands, face, or mouth after receiving the injection.

These could be symptoms of a serious kidney problem.
Levofloxacin may cause diarrhea, and in some cases it can be severe. It may occur 2 months or more after you stop receiving this medicine.

Do not use a sun lamp or tanning bed or booth.
If you have a severe reaction from the sun, check with your doctor.
