Ansaid (flurbiprofen) is a nonsteroidal anti-inflammatory drug (NSAID). Flurbiprofen works by reducing hormones that cause inflammation and pain in the body. Ansaid is used to treat pain or inflammation caused by arthritis, ankylosing spondylitis, tendinitis, bursitis, gout, or menstrual cramps. Ansaid may also be used for purposes not listed in this medication guide. You should not use Ansaid if you are allergic to flurbiprofen or any other NSAID (naproxen, ibuprofen, celecoxib, diclofenac, indomethacin, meloxicam, and others).

To make sure Ansaid is safe for you, tell your doctor if you have ever had:

  • kidney disease
  • liver disease
  • high blood pressure, heart disease, or congestive heart failure
  • asthma or other breathing disorder
  • swelling or fluid retention
  • a bleeding or blood clotting disorder
  • stomach ulcers
  • ulcerative colitis
  • Crohn’s disease

It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant. NSAID medicines can cause ulcers and bleeding in the stomach and intestines at any time during treatment. If you take Ansaid on a regular basis, your doctor will want to check your progress at regular visits. Your blood and urine may be tested to check for unwanted effects. Do not take two doses of Ansaid at the same time. Overdose symptoms may include drowsiness, shallow breathing, slow heartbeat, fainting, or seizure (convulsions).



Ansaid is rapidly absorbed from the gastrointestinal tract with peak plasma concentrations occurring 1 to 2 hours after administration. The bioavailability of Ansaid is approximately 100%.

The plasma protein binding of Ansaid is 99%, primarily to albumin.

flurbiprofen is metabolized in the liver by cytochrome P450 enzymes, primarily by CYP2C9, to several metabolites, the major ones being 5-hydroxyflurbiprofen and 3′-hydroxyflurbiprofen.

The elimination half-life of flurbiprofen ranges from 1.3 to 4 hours.
