Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.

Some products that may interact with this drug include: mifepristone, acetazolamide, "blood thinners" (such as warfarin, heparin), corticosteroids (such as prednisone), dichlorphenamide, methotrexate, valproic acid, herbal medications (such as ginkgo biloba).

Before using this product, consult your doctor if you have recently received certain live vaccines (such as varicella vaccine, live flu vaccine).

Check all prescription and nonprescription medicine labels carefully since many medications contain pain relievers/fever reducers known as NSAIDs (non-steroidal anti-inflammatory drugs such as ibuprofen, ketorolac, naproxen). To prevent an overdose of aspirin, read the labels carefully before taking other pain relievers or cold products to make sure they do not contain aspirin. Ask your pharmacist about using these products safely.

Daily use of NSAIDs (such as ibuprofen) may decrease aspirin's ability to prevent heart attack/stroke. If you are taking low-dose aspirin for prevention of heart attack/stroke, consult your doctor or pharmacist for more details and to discuss other possible treatments (such as acetaminophen) for your pain/fever.

This medication may interfere with certain lab tests (such as certain urine sugar tests), possibly causing false test results. Make sure lab personnel and all your doctors know you use this drug.
