Uses
Diflunisal is used to relieve mild to moderate pain from various conditions. It also reduces pain, swelling, and joint stiffness caused by arthritis. Reducing these symptoms helps you do more of your normal daily activities. This medication is known as a nonsteroidal anti-inflammatory drug (NSAID).
This medication is not recommended for use in children under 12 years of age.
Warning
Nonsteroidal anti-inflammatory drugs (including diflunisal) may rarely increase the risk for a heart attack or stroke. This effect can happen at any time while taking this drug but is more likely if you take it for a long time. The risk may be greater in older adults or if you have heart disease or increased risk for heart disease (for example, due to smoking, family history of heart disease, or conditions such as high blood pressure or diabetes). Do not take this drug right before or after heart bypass surgery (CABG).
Also, this drug may rarely cause serious (rarely fatal) bleeding from the stomach or intestines. This effect can occur without warning symptoms at any time while taking this drug. Older adults may be at higher risk for this effect.
Stop taking diflunisal and get medical help right away if you notice any of these rare but serious side effects: stomach/abdominal pain that doesn't go away, black/tarry stools, vomit that looks like coffee grounds, chest/jaw/left arm pain, shortness of breath, unusual sweating, confusion, weakness on one side of the body, trouble speaking, sudden vision changes.
Talk to your doctor or pharmacist about the benefits and risks of taking this drug.

How to Use This Medication
Read the Medication Guide provided by your pharmacist before you start using diflunisal and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth with a full glass of water (8 ounces or 240 milliliters) unless your doctor directs you otherwise. Do not lie down for at least 10 minutes after taking this drug. Take this medication with food/milk or right after meals to prevent stomach upset.
Swallow this medication whole. Do not crush or chew the tablets. Doing so may increase side effects.
The dosage is based on your medical condition and response to treatment. Do not take more than 1,500 milligrams per day. To minimize side effect risks (such as stomach bleeding), use this medication at the lowest effective dose for the shortest possible length of time. Do not increase your dose or take it more often than prescribed. For ongoing conditions such as arthritis, keep taking it as directed by your doctor. Discuss the risks and benefits with your doctor or pharmacist.
In certain conditions (such as arthritis), it may take up to 2 weeks of regular use before the full benefits of this drug take effect.
If you are taking this drug on an "as needed" basis (not on a regular schedule), remember that pain medications work best if they are used as the first signs of pain occur. If you wait until the pain has significantly worsened, the medicine may not work as well.
Tell your doctor if your condition gets worse.
