Can I take this if I am pregnant or trying to get pregnant or if I am breastfeeding?

Ceftizoxime has been assigned to pregnancy category B by the FDA. Animal data failed to reveal evidence of fetal harm. There are no controlled data in human pregnancy. Ceftizoxime should only be given during pregnancy when need has been clearly established.

Ceftizoxime is excreted into human milk in small amounts. Adverse effects in the nursing infant are unlikely. Other cephalosporins have been classified as compatible with breast-feeding by the American Academy of Pediatrics.

I am on so many medications; do I have to take them all?
This is called polypharmacy—many different medications being used at the same time by one person. Sometimes, being on multiple medications is acceptable and appropriate but at other times it may be problematic. If you are receiving your medications from multiple physicians you need to ensure that they all know what medications you are taking. The best way to do this is to make a list of all the medications you are currently using, including all nutritional supplements, homeopathic remedies, vitamins and over-the-counter drugs (if possible, also include all the diseases you have been diagnosed with). Give a copy to every doctor who takes care of you so they have it on file, this way they can avoid duplicating medications and perhaps even try to consolidate some. After every doctor's visit remember to update the list accordingly. Also, as much as you possibly can, try to use the same pharmacy to fill all your prescriptions, this way any potential drug interactions can be caught and averted.
