The mechanism underlying this interference is unknown. Patients taking both flurbiprofen and a beta-blocker should be monitored to ensure that a satisfactory hypotensive effect is achieved.
Diuretics Clinical studies, as well as post marketing observations, have shown that ANSAID flurbiprofen can reduce the natriuretic effect of furosemide and thiazides in some patients. This response has been attributed to inhibition of renal prostaglandin synthesis.
Lithium NSAIDs have produced an elevation of plasma lithium levels and a reduction in renal lithium clearance. These effects have been attributed to inhibition of renal prostaglandin synthesis by the nonsteroidal anti-inflammatory drug. Thus, when nonsteroidal anti-inflammatory drugs and lithium are administered concurrently, subjects should be observed carefully for signs of lithium toxicity.
Methotrexate Nonsteroidal anti-inflammatory drugs have been reported to competitively inhibit methotrexate accumulation in rabbit kidney slices. This may indicate that they could enhance the toxicity of methotrexate. Caution should be used when nonsteroidal anti-inflammatory drugs are administered concomitantly with methotrexate. Patients with known CV disease or risk factors for CV disease may be at greater risk.
To minimize the potential risk for an adverse CV event in patients treated with an NSAID, the lowest effective dose should be used for the shortest duration possible. Physicians and patients should remain alert for the development of such events, even in the absence of previous CV symptoms. There is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious CV thrombotic events associated with NSAID use. Patients taking thiazides or loop diuretics may have impaired response to these therapies when taking NSAIDs.
These serious adverse events can occur at any time, with or without warning symptoms, in patients treated with NSAIDs. These trends continue with longer duration of use, increasing the likelihood of developing a serious GI event at some time during the course of therapy.
Patients and physicians should remain alert for signs and symptoms of GI ulcerations and bleeding during NSAID therapy and promptly initiate additional evaluation and treatment if a serious GI event is suspected. Renal toxicity has also been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion. In these patients, administration of a nonsteroidal anti-inflammatory drug may cause a dose-dependent reduction in prostaglandin formation and, secondarily, in renal blood flow, which may precipitate overt renal decompensation.
Patients at greatest risk of this reaction are those with impaired renal function, heart failure, liver dysfunction, those taking diuretics and ACE inhibitors, and the elderly. Advanced Renal Disease In clinical studies, the elimination half-life of flurbiprofen was unchanged in patients with renal impairment.
Flurbiprofen metabolites are eliminated primarily by the kidneys. Elimination of 4'-hydroxy-flurbiprofen was reduced in patients with moderate to severe renal impairment.
Therefore, treatment with Ansaid is not recommended in these patients with advanced renal disease. Ansaid should not be given to patients with the aspirin triad. Emergency help should be sought in cases where an anaphylactoid reaction occurs. These serious events may occur without warning. Patients should be informed about the signs and symptoms of serious skin manifestations and use of the drug should be discontinued at the first appearance of skin rash or any other sign of hypersensitivity.
Pregnancy In late pregnancy, as with other NSAIDs, Ansaid should be avoided because it may cause premature closure of the ductus arteriosus.
Precautions General Ansaid cannot be expected to substitute for corticosteroids or to treat corticosteroid insufficiency. Abrupt discontinuation of corticosteroids may lead to disease exacerbation. Patients on prolonged corticosteroid therapy should have their therapy tapered slowly if a decision is made to discontinue corticosteroids.
The pharmacological activity of Ansaid in reducing fever and inflammation may diminish the utility of these diagnostic signs in detecting complications of presumed noninfectious, painful conditions.
These laboratory abnormalities may progress, may remain unchanged, or may be transient with continuing therapy. In addition, rare cases of severe hepatic reactions, including jaundice, fulminant hepatitis, liver necrosis, and hepatic failure, some of them with fatal outcomes have been reported. If clinical signs and symptoms consistent with liver disease develop, or if systemic manifestations occur eg, eosinophilia, rash, etc. Check the label to see if a medicine contains aspirin, ibuprofen, ketoprofen, or naproxen.
It may increase your risk of stomach bleeding. What other drugs will affect flurbiprofen Ansaid? Tell your doctor if you are taking an antidepressant such as citalopram Celexa , duloxetine Cymbalta , escitalopram Lexapro , fluoxetine Prozac, Sarafem, Symbyax , fluvoxamine Luvox , paroxetine Paxil , sertraline Zoloft , or venlafaxine Effexor. Taking any of these drugs with flurbiprofen may cause you to bruise or bleed easily. Tell your doctor about all other medicines you use, especially: This medicine may cause stomach bleeding.
Daily use of alcohol and tobacco , especially when combined with this medicine, may increase your risk for stomach bleeding. Limit alcohol and stop smoking. Consult your doctor or pharmacist for more information.
This medication may make you more sensitive to the sun. Case-control and cohort epidemiological studies showed that concomitant use of drugs that interfere with serotonin reuptake and an NSAID may potentiate the risk of bleeding more than an NSAID alone.
Monitor patients with concomitant use of flurbiprofen with anticoagulants e. Concurrent administration of aspirin lowers serum flurbiprofen concentrations.
The clinical significance of this interaction is not known. Concomitant use of flurbiprofen and analgesic doses of aspirin is not generally recommended because of the increased risk of bleeding [see Warnings and Precautions 5 ]. Flurbiprofen is not a substitute for low dose aspirin for cardiovascular protection. These effects are usually reversible. Assess renal function at the beginning of the concomitant treatment and periodically thereafter.
Clinical studies, as well as post-marketing observations, showed that NSAIDs reduced the natriuretic effect of loop diuretics e. During concomitant use of flurbiprofen with diuretics, observe patients for signs of worsening renal function, in addition to assuring diuretic efficacy including antihypertensive effects [see Warnings and Precautions 5 ]. The concomitant use of flurbiprofen with digoxin has been reported to increase the serum concentration and prolong the half-life of digoxin [see Clinical Pharmacology During concomitant use of flurbiprofen and digoxin, monitor serum digoxin levels.
NSAIDs have produced elevations in plasma lithium levels and reductions in renal lithium clearance. During concomitant use of flurbiprofen and lithium, monitor patients for signs of lithium toxicity.
During concomitant use of flurbiprofen and methotrexate, monitor patients for methotrexate toxicity. During concomitant use of flurbiprofen and cyclosporine, monitor patients for signs of worsening renal function.
Concomitant use of flurbiprofen and pemetrexed may increase the risk of pemetrexed-associated myelosuppression, renal, and GI toxicity see the pemetrexed prescribing information. NSAIDs with short elimination half-lives e.
In the absence of data regarding potential interaction between pemetrexed and NSAIDs with longer half-lives e. Corticosteroids Concomitant use of corticosteroids with flurbiprofen may increase the risk of GI ulceration or bleeding. Monitor patients with concomitant use of flurbiprofen with corticosteroids for signs of bleeding [see Warnings and Precautions 5.
Avoid use of NSAIDs, including flurbiprofen, in pregnant women starting at 30 weeks of gestation third trimester. There are no adequate and well-controlled studies of flurbiprofen in pregnant women. Data from observational studies regarding potential embryo-fetal risks of NSAID use in women in the first or second trimesters of pregnancy are inconclusive. In the general U.
