Uses:
This medication is used to treat a wide variety of bacterial infections. This medication is known as a carbapenem-type antibiotic. It works by stopping the growth of bacteria. This antibiotic treats only bacterial infections. It will not work for viral infections (e.g., common cold, flu). Unnecessary use or misuse of any antibiotic can lead to its decreased effectiveness.
Missed Dose
If you miss a dose, use it as soon as you remember. If it is near the time of the next dose, skip the missed dose and resume your usual dosing schedule. Do not double the dose to catch up.
How To Use
This medication is given by injection into a muscle or vein, usually every 6 to 8 hours or as directed by your doctor. Read and learn all preparation and usage instructions supplied by the manufacturer. If your product needs to be mixed, follow all instructions for proper mixing with the correct IV fluids. Consult your pharmacist for details. Before using, check the product visually for particles or discoloration. If either is present, do not use the liquid. Antibiotics work best when the amount of medicine in your body is kept at a constant level. Therefore, use this drug at evenly spaced intervals. The dosage is based on your medical condition and response to treatment. Continue to use this medication until the full prescribed treatment period is finished, even if symptoms disappear after a few days. Stopping the medication too early may result in a return of the infection. Learn how to store and discard needles and medical supplies safely. Consult your pharmacist for details.

Do not start, stop, or change the dosage of any medicine before checking with your doctor or pharmacist first. Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of: live bacterial vaccines, ganciclovir, probenecid, other antibiotics, divalproate/valproic acid. This medication may decrease the effectiveness of combination-type birth control pills. This can result in pregnancy. Ask your doctor or pharmacist for details.

A different medication may be necessary in that case. Laboratory and/or medical tests (e.g., complete blood count, kidney/liver function tests) may be performed periodically to monitor your progress or check for side effects. Consult your doctor for more details.
