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

This is ceftazidime. You may hear it called by the brand name 'Fortaz'. 

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

Ceftazidime belongs to a group of antibiotics called 'cephalosporins'. It is similar to penicillin. You should tell your doctor if you are allergic to penicillins, cephalosporins or any antibiotics. 

Ceftazidime is commonly given as an infusion into a vein. It can also be given as an injection into a large muscle. 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 ceftazidime well and start feeling better soon. Some side effects can occur, like mild diarrhea, nausea or dizziness. 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 ceftazidime, this includes allergic reactions. You should 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. 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 that lasts more than 2 days, even if it happens months after your last dose. 

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