Warning

This medication may rarely cause a severe intestinal condition due to a bacteria called C. difficile. This condition may occur weeks to months after treatment has stopped.

This antibiotic treats only bacterial infections. It will not work for viral infections (such as common cold, flu). Using any antibiotic when it is not needed can cause it to not work for future infections.

This medication should not be used to treat meningitis.

How To Use

This medication is given by injection into a vein or muscle as directed by your doctor, usually 2 to 4 times a day. The dosage is based on your medical condition and response to treatment. In children, the dosage is also based on weight.

If you are giving this medication to yourself at home, learn all preparation and usage instructions from your health care professional. Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Learn how to store and discard medical supplies safely.

Antibiotics work best when the amount of medicine in your body is kept at a constant level. Use this drug at evenly spaced intervals.
