Let's take a minute to talk about your medication. This is Invanz. It is an antibiotic that treats infections caused by germs called 'bacteria'. It does not treat infections caused by viruses, like the common cold. It can also be used to help prevent infections from certain surgeries. This medicine 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. Invanz is given as an infusion into a vein. It can also be given as an injection into a large muscle. 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 Invanz well and start feeling better soon. Some side effects can occur, like mild nausea, headache or diarrhea. When taking any antibiotic, females should watch for a vaginal yeast infection and obtain treatment if one occurs. As with any medicine, rare but more serious side effects can occur. With Invanz, this includes allergic reactions or seizures. To help keep your 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 with Invanz, you should finish the full course. Otherwise, the infection could return and become hard to treat.
