What is diflunisal used for?
Diflunisal is a nonsteroidal anti-inflammatory drug (NSAID). It’s used to reduce pain and inflammation, most commonly for conditions such as arthritis (for example, osteoarthritis and rheumatoid arthritis). It can also be used to treat other painful inflammatory conditions that doctors decide NSAIDs are appropriate for.
How does diflunisal work?
Like other NSAIDs, diflunisal works by lowering the production of prostaglandins, which drive pain, inflammation, and fever. This helps relieve pain and swelling, and can improve joint function in arthritis and related conditions.
What are common side effects people report?
NSAIDs can cause side effects such as stomach upset, heartburn, nausea, and abdominal pain. More serious risks include stomach or intestinal bleeding, kidney problems, and increased cardiovascular risk in some patients, especially with higher doses or longer use.
Who should avoid diflunisal or use extra caution?
People are often advised to use diflunisal cautiously or avoid it if they have:
- A history of stomach ulcers or gastrointestinal bleeding
- Significant kidney disease
- Certain heart or blood-vessel conditions (or higher cardiovascular risk)
- Allergy or prior reaction to aspirin or other NSAIDs
It’s also important to be careful with diflunisal if you take other medicines that can increase bleeding risk or affect kidneys.
Drug interactions: what to watch for?
Diflunisal can interact with other drugs in ways that increase side effects. Key examples of interactions doctors commonly review include:
- Blood thinners (higher bleeding risk)
- Other NSAIDs (higher risk of stomach and kidney side effects)
- Steroids (higher GI bleeding risk)
- Certain blood pressure medicines and diuretics (possible kidney effects)
- Lithium or methotrexate (possible increased drug levels/toxicity)
How long does diflunisal take to work?
For many pain-related uses, NSAID effects can begin within hours after taking a dose. Relief may build over the first few days if it’s being used for a condition like arthritis, but the exact timing depends on the person and the dose.
What’s the difference between diflunisal and other NSAIDs?
Diflunisal is an NSAID like ibuprofen or naproxen, but dosing and side-effect profiles can differ. In practice, clinicians choose among NSAIDs based on the condition being treated, patient risk factors (stomach, kidney, heart), and how the patient has tolerated similar drugs before.
Is diflunisal available as a generic?
Diflunisal is commonly marketed as a generic NSAID in many places, but availability can vary by country and pharmacy supply.
