Uses

What is Ertapenem used for?

Ertapenem is commonly used to prevent and 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 should I take Ertapenem?

This medication is given by injection into a muscle or vein as directed by your doctor, usually once or twice daily. If you are using this medication to prevent an infection, it is given by injection into a vein by a health care professional. It is given as directed by your doctor, usually 1 hour before your surgery.

If this medication is given by injection into a muscle, follow the manufacturer’s directions for mixing with lidocaine 1 percent solution. Do not use this solution for injection into a vein.

If you are using this medication 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.

The dosage is based on your medical condition and response to treatment. In children, the dosage is also based on age and weight.

For the best effect, use this antibiotic at evenly spaced times. To help you remember, use this medication at the same time(s) every day.

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.

Tell your doctor if your condition lasts or gets worse.

How do I store Ertapenem?

Prior to reconstitution, store vials at ≤25°C (77°F). The reconstituted IM solution should be used within 1 hour after preparation. The reconstituted IV solution may be stored at room temperature (25°C [77°F]) and used within 6 hours, or stored for 24 hours under refrigeration (5°C [41°F]) and used within 4 hours after removal from refrigeration. Do not freeze.

If you need to store this medicine at home, talk with your doctor, nurse, or pharmacist about how to store it.

Precautions & warnings

What should I know before using Ertapenem?

Before using ertapenem, tell your doctor or pharmacist if you are allergic to it; or to penicillins or cephalosporins; or if you have any other allergies. Before getting ertapenem by injection into a muscle, also tell your doctor or pharmacist if you are allergic to any amide-type local anesthetics (such as lidocaine). This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

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

Ertapenem may cause live bacterial vaccines (such as typhoid vaccine) to not work as well. Do not have any immunizations/vaccinations while using this medication unless your doctor tells you to.

Swelling, redness, pain, or soreness at the injection site may occur. Upset stomach, headache, nausea, vomiting, or diarrhea may also occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Precautions

Intramuscular administration is contraindicated in patients with amide anesthetic hypersensitivity.

Serious and occasionally fatal hypersensitivity reactions have been reported with antibiotics. The drug should be discontinued immediately at the first appearance of a skin rash or other signs of hypersensitivity. Severe, acute hypersensitivity reactions may require treatment with epinephrine and other resuscitative measures including oxygen, intravenous fluids, antihistamines, corticosteroids, cardiovascular support and airway management as clinically indicated.

Clostridium difficile associated diarrhea (CDAD) has been reported with almost all antibiotics and may potentially be life-threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhea following ertapenem therapy. Mild cases generally improve with discontinuation of the drug, while severe cases may require supportive therapy and treatment with an antimicrobial agent effective against C difficile. Hypertoxin producing strains of C difficile cause increased morbidity and mortality; these infections can be resistant to antimicrobial treatment and may necessitate colectomy.

Ertapenem has been associated with seizures and other CNS side effects such as confusion, most commonly in patients with CNS disorders such as brain lesions, history of seizures, bacterial meningitis, or renal impairment. Recommended dosages should not be exceeded, especially in patients with risk factors. Neurologic evaluation, anticonvulsant therapy, and ertapenem dosage adjustment or discontinuation are recommended for patients who experience tremors, myoclonus or seizures.

Periodic renal, hepatic and hematopoietic monitoring is recommend during prolonged therapy.

Efficacy and safety have not been established in patients less than 3 months of age. Ertapenem is not recommended in the treatment of meningitis in pediatric patients due to insufficient CSF penetration.

Dialysis

For hemodialysis patients, the recommended dose is 500 mg IV once daily, given at least 6 hours before hemodialysis. If administered within 6 hours before hemodialysis, a supplementary dose of 150 mg is recommended after the hemodialysis session.

There are no data regarding peritoneal dialysis or hemofiltration.

Other Comments

Intravenous ertapenem doses should be infused over 30 minutes.

Alternatively, ertapenem may be given by intramuscular injection for up to 7 days, where appropriate. The intravenous route is preferred for severe or life-threatening infections and for patients with reduced resistance (i.e., malnutrition, trauma, surgery, heart failure, malignancy, or shock).
