Drugs & Medications

Merrem intravenous



Meropenem 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.

How to use Merrem intravenous

This medication is given by injection into a vein, usually every 8 hours or as directed by your doctor. 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. Therefore, use this drug at evenly spaced intervals.

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 allow bacteria to continue to grow, which may result in a return of the infection.

Tell your doctor if your condition persists or worsens.

Side Effects

Swelling, redness, pain, or soreness at the injection site may occur. This medication may also rarely cause upset stomach, headache, nausea, vomiting, constipation, or diarrhea. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor right away if you have any serious side effects, including: easy bruising/bleeding, hearing changes (e.g., decreased hearing, ringing in the ears), mental/mood changes (e.g., confusion), swollen tongue, numb/tingling skin.

Get medical help right away if any of these rare but very serious side effects occur: seizures, unusual weakness.

This medication may rarely cause a severe intestinal condition (Clostridium difficile-associated diarrhea) due to a type of resistant bacteria. This condition may occur weeks to months after treatment has stopped. Do not use anti-diarrhea products or narcotic pain medications if you have any of these symptoms because these products may make them worse. Tell your doctor right away if you develop: persistent diarrhea, abdominal or stomach pain/cramping, blood/mucus in your stool.

Use of this medication for prolonged or repeated periods may result in oral thrush or a new vaginal yeast infection. Contact your doctor if you notice white patches in your mouth, a change in vaginal discharge, or other new symptoms.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: brain disorders (e.g., seizures, head injury, tumor), kidney disease, stomach/intestinal diseases (e.g., colitis).

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions.

This could result in pregnancy. If you use hormonal birth control, ask your doctor or pharmacist for more details.
