Let's take a minute to talk about your medication. 

This is meropenem. You may hear it called by the brand name 'Merrem'. 

Meropenem is a powerful antibiotic that treats infections caused by germs called 'bacteria'. It does not treat infections caused by viruses, like the common cold. 

Meropenem is similar to penicillins. You should tell your doctor if you are allergic to penicillins or any antibiotics. Also, tell your doctor about all of the medicines you take, especially if you take medicines for seizures. 

Meropenem is given as an infusion into a vein. Tell your caregiver right away if you notice unusual changes to your body, like a rash, itching, or swelling or tingling of your face or mouth. Your caregiver will monitor the site where you get your dose. You can help keep an eye on the area, and report any swelling or pain. 

Most patients tolerate meropenem well and start feeling better soon. Some side effects can occur, like mild nausea, headache and either diarrhea or constipation. When taking any antibiotic, females should watch for a vaginal yeast infection and obtain treatment if one occurs. This medicine can affect your ability to be alert. Wait until you know how it affects you before doing tasks like driving. 

As with any medicine, rare but more serious side effects can occur. With meropenem, this includes allergic reactions, seizures or feeling pain, tingling or numbness in your body. To help keep this medicine safe for you, your doctor will follow you closely. Also, you should tell your doctor if you have diarrhea that is bloody or lasts more than 2 days, even if it happens months after your last dose. 

For best results, you should finish the full course. Otherwise, the infection could return and become hard to treat.
