Before taking oxaprozin,
tell your doctor and pharmacist if you are allergic to oxaprozin, aspirin, or other NSAIDs such as ibuprofen (Advil, Motrin) and naproxen (Aleve, Naprosyn), any other medications, or any of the inactive ingredients in oxaprozin tablets. Ask your pharmacist for a list of the inactive ingredients.
tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention the medications listed in the IMPORTANT WARNING section and any of the following: angiotensin-converting enzyme (ACE) inhibitors such as benazepril (Lotensin, in Lotrel), captopril, enalapril (Vasotec, in Vaseretic), fosinopril (Monopril), lisinopril (in Zestoretic), moexipril (Univasc), perindopril (Aceon, in Prestalia), quinapril (Accupril, in Quinaretic), ramipril (Altace), and trandolapril (Mavik, in Tarka); angiotensin receptor blockers (ARBs) such as azilsartan (Edarbi, in Edarbyclor), candesartan (Atacand, in Atacand HCT), eprosartan (Teveten), irbesartan (Avapro, in Avalide), losartan (Cozaar, in Hyzaar), olmesartan (Benicar, in Azor, in Benicar HCT, in Tribenzor), telmisartan (Micardis, in Micardis HCT, in Twynsta), and valsartan (in Exforge HCT); beta blockers such as atenolol (Tenormin, in Tenoretic), labetalol (Trandate), metoprolol (Lopressor, Toprol XL, in Dutoprol), nadolol (Corgard, in Corzide), and propranolol (Hemangeol, Inderal, Innopran); diuretics ('water pills'); glyburide (Glynase, Micronase); lithium (Lithobid); and methotrexate (Otrexup, Rasuvo, Trexall). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
tell your doctor if you have or ever had asthma, especially if you also have frequent stuffed or runny nose or nasal polyps; heart failure; swelling of the hands, feet, ankles, or lower legs; or kidney or liver disease.
tell your doctor if you are pregnant, especially if you are in the last few months of your pregnancy, you plan to become pregnant, or you are breastfeeding. If you become pregnant while taking oxaprozin, call your doctor.
talk to your doctor about the risks and benefits of taking oxaprozin if you are 65 years of age or older. Older adults should take lower doses of oxaprozin for only a short time period because higher doses used regularly may not be more effective and are more likely to cause serious side effects.
if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking oxaprozin.
plan to avoid unnecessary or prolonged exposure to sunlight and to wear protective clothing, sunglasses, and sunscreen. Oxaprozin may make your skin sensitive to sunlight.
