What is the most important information I should know about ertapenem (Invanz)?

You should not use this medication if you are allergic to ertapenem or to any other antibiotic.

Before using ertapenem, tell your doctor if you have kidney disease, a seizure disorder such as epilepsy, a history of head injury or brain tumor, or if you are allergic to numbing medicine such as lidocaine or Novocain.

To be sure this medication is not causing harmful effects, your blood may need to be tested often. Your kidney or liver function may also need to be tested. Visit your doctor regularly.

Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, stop using ertapenem and call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to.

Use this medication for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Ertapenem will not treat a viral infection such as the common cold or flu.
