Flurbiprofen is a prescription non-steroidal anti-inflammatory drug (NSAID). It's used to relieve symptoms of rheumatoid arthritis (RA) or osteoarthritis (OA) in adults. Flurbiprofen comes as tablets that are taken by mouth. The total daily dosage is typically split into smaller doses and taken 2 to 4 times per day. Side effects include stomach pain, constipation or diarrhea, and nausea. Brand name Ansaid has been discontinued.
Flurbiprofen is a non-steroidal anti-inflammatory drug (NSAID). It blocks proteins in your body called cyclooxygenase. This helps lessen inflammation, swelling, and pain.

Avoid alcohol while you're taking flurbiprofen. Alcohol can raise your risk for stomach upset, stomach bleeds, and stomach ulcers. Talk with your healthcare team if you regularly drink alcohol and it's difficult for you to stop. They can recommend resources to help you stop drinking or discuss other treatment options to help with your condition.
Flurbiprofen can raise the risk for stomach bleeding. Tell your prescriber right away if you have unexplained vomiting or stomach pain or blood in your vomit or stool. They can let you know whether you need more medical attention.
Flurbiprofen might raise your blood pressure. If you already have high blood pressure, your prescriber might ask you to check your blood pressure at home more often. If needed, they might make changes to your blood pressure medications.
Don't take flurbiprofen with other NSAIDs, such as ibuprofen (Motrin, Advil). Doing so puts you at higher risk for stomach bleeds without additional benefit to pain. NSAIDs are commonly found in over-the-counter pain and cold medications. Talk with your healthcare professional or pharmacist if you're not sure whether you're already taking an NSAID.
Make sure to tell your prescriber and pharmacist about all of the medications you're taking or planning to take. Flurbiprofen can interact with many medications, such as blood pressure medications and blood thinners (including aspirin). These interactions can raise your risk for side effects. Your care team can check that your medications are safe to take together.
If you're pregnant, talk to your healthcare team about safe alternatives for pain instead of flurbiprofen. The FDA recommends avoiding NSAIDs like flurbiprofen during the second half of pregnancy because NSAIDs might harm your unborn baby or cause complications during delivery. It's not clear how safe flurbiprofen is in the first half of pregnancy either.
The levels of flurbiprofen are expected to be low in breast milk. But to be safe, make sure to talk to your care team about the risks and benefits of taking flurbiprofen if you're breastfeeding.
Flurbiprofen can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Older adults | History of stomach bleeding or bleeding problems | Liver problems | Taking other medications that raise your risk of bleeds | Drinking alcohol | Smoking | Taking flurbiprofen for a long time
Taking flurbiprofen can raise your risk for stomach ulcers (sores) and bleeds, which can be life-threatening. These stomach injuries can happen at any time while you're taking flurbiprofen. Tell your prescriber or pharmacist about all of your medical conditions and medications before you start flurbiprofen so they can talk with you about your risk for stomach bleeding.
Oftentimes, people who have stomach bleeds don't have noticeable symptoms, especially if the bleeding is slow and happens over a long period of time. Stomach ulcers can feel like a gnawing pain in the stomach area. Seek medical attention right away if you're feeling faint, vomiting blood, have bloody or dark stools, or have severe stomach pain or discomfort that doesn't go away while you're taking flurbiprofen.
Risk factors: Heart problems | Taking higher doses of flurbiprofen | Taking flurbiprofen for a long time | Past or planned heart surgery
Flurbiprofen might raise your risk of having blood clots, which can sometimes lead to a heart attack or stroke. Talk to your prescriber before you start taking flurbiprofen if you have heart problems. Don't take this medication if you had, or will have, heart surgery.
To lower your risk of blood clots, heart attack, and stroke, your prescriber will recommend that you take the lowest dose of flurbiprofen for the shortest time needed to treat your condition. Call 911 or get immediate help if you experience chest pain, shortness of breath, weakness on one side of your body, or trouble speaking or walking. These can be signs of a serious blood clot.
Risk factors: Heart problems
Flurbiprofen can cause your body to hold onto extra fluid. This can raise your blood pressure or put you at risk for heart failure. Tell your prescriber if you have a history of a heart condition or if you're taking blood pressure medications before you start flurbiprofen. Your prescriber will also check for heart problems before your treatment with flurbiprofen starts. Contact your healthcare team if you have unexplained fainting, chest pain with physical activity, or irregular heartbeat while you're taking flurbiprofen. These can be signs of heart problems from fluid build-up.
Risk factors: Older adults | Kidney problems | Heart failure | Liver problems | Taking other medications that can cause kidney problems
Taking NSAIDs, like flurbiprofen, over a longer period of time can cause injury to the kidneys. Your risk is higher if you're of older age, if you have certain medical problems like kidney problems, or if you take medications that can cause kidney damage such as diuretics (water pills). Contact your care team if you develop any signs or symptoms of kidney problems, including changes in your need to urinate, tiredness, dry and itchy skin, low appetite, and muscle cramps.
Risk factors: History of liver problems
Some people who took flurbiprofen had higher liver enzyme levels in their blood, which can mean harm to your liver. Although rare, there have been reports of serious liver problems that can lead to liver failure. Get medical attention right away if you notice swelling of your stomach; stomach pain; yellowing of your skin or the whites of your eyes; stool changes (black, tarry, or bloody stools); nausea; or dark or brown urine. These can be signs of liver damage, and you might need to stop taking flurbiprofen to prevent further harm.
Risk factors: Aspirin or NSAID allergy | Aspirin-sensitive asthma | Asthma with rhinitis (runny or stuffy nose), with or without nasal polyps
Severe allergic reactions to flurbiprofen are possible, including life-threatening reactions like facial swelling, shock, and anaphylaxis. Tell your prescriber if you have an allergy to aspirin or other NSAIDs; you might be at risk for an allergic reaction to flurbiprofen. Get medical help right away if you notice hives, swelling of the lips or tongue, or difficulty breathing after you take flurbiprofen.
Although rare, flurbiprofen can also cause serious skin reactions, including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS). Stop taking flurbiprofen and get medical attention right away if you notice changes in your skin, such as rash, blisters, skin reddening, or skin peeling.
Flurbiprofen can cause harm to an unborn baby, especially if it's taken in the second half of pregnancy (after week 20). The medication can raise the risk for serious complications, such as heart or kidney problems in your unborn baby or problems during delivery. Speak to your prescriber about the risks and benefits of taking flurbiprofen if you're pregnant.
Risk factors: Taking with other blood thinners (e.g. aspirin, warfarin) | Taking with selective serotonin reuptake inhibitors (SSRIs) and serotonin norepinephrine reuptake inhibitors (SNRIs) | Blood-clotting problems
NSAIDs like flurbiprofen can raise your risk for bleeding. Let a healthcare professional know if you bleed more easily, if bleeding takes longer to stop, or if bleeding doesn't stop while you're taking this medication.
Adults: The typical dose is 200 mg to 300 mg by mouth per day, split into smaller doses and given two to four times per day. The maximum single dose is 100 mg at a time.
