What is the most important information I should know about oxaprozin?
This medicine can increase your risk of life-threatening heart or circulation problems, including heart attack or stroke. Do not use this medicine just before or after having heart bypass surgery (also called coronary artery bypass graft, or CABG). Seek emergency medical help if you have symptoms of heart or circulation problems, such as chest pain, weakness, shortness of breath, slurred speech, or problems with vision or balance.

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

Oxaprozin has been assigned to pregnancy category C by the FDA. Animal studies involving mice and rats failed to reveal evidence of teratogenicity. However, in rabbit studies at doses of 7.5 to 30 mg/kg/day, fetal malformations were occasionally observed. There are no controlled data in human pregnancy. Use late in pregnancy may result in premature closure on the ductus arteriosus and prolong labor and delivery. Oxaprozin is only recommended during pregnancy when benefit outweighs risk. Oxaprozin should be avoided near term.

There are no data on the excretion of oxaprozin into human milk. The manufacturer recommends that due to the potential for serious adverse reactions in nursing infants, a decision should be made to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.

What should I discuss with my healthcare provider before taking oxaprozin?
Taking an NSAID can increase your risk of life-threatening heart or circulation problems, including heart attack or stroke. This risk will increase the longer you use an NSAID. Do not use this medicine just before or after having heart bypass surgery (also called coronary artery bypass graft, or CABG). NSAIDs can also increase your risk of serious effects on the stomach or intestines, including bleeding or perforation (forming of a hole).

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.
