What is Etodolac?

Etodolac (Etodolac) is a nonsteroidal anti-inflammatory drug (NSAID). Etodolac works by reducing hormones that cause inflammation and pain in the body.

Etodolac is used to treat mild to moderate pain, osteoarthritis, or rheumatoid arthritis.

Etodolac may also be used for purposes not listed in this medication guide.

Etodolac indications

An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.

Carefully consider the potential benefits and risks of Etodolac Extended-Release Tablets and other treatment options before deciding to use Etodolac Extended-Release Tablets. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals.

Etodolac Extended-Release Tablets are indicated:

For relief of signs and symptoms of juvenile arthritis
For relief of the signs and symptoms of rheumatoid arthritis
For relief of the signs and symptoms of osteoarthritis

How should I use Etodolac?

Ask your health care provider any questions you may have about the proper use of Etodolac extended-release tablets.

Uses of Etodolac in details

There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.

Etodolac is used to relieve painful conditions of the bone, joints and soft tissues such as inflammatory arthritis (rheumatoid arthritis) and advanced osteoarthritis.

Etodolac description

Etodolac is a non-steroidal anti-inflammatory drug (NSAID) with anti-inflammatory, analgesic and antipyretic properties. Its therapeutic effects are due to its ability to inhibit prostaglandin synthesis. It is indicated for relief of signs and symptoms of rheumatoid arthritis and osteoarthritis.

Etodolac dosage

Etodolac Dosage

Generic name: Etodolac

Dosage form: Capsules and Tablets

The information at is not a substitute for medical advice. Always consult your doctor or pharmacist.

Carefully consider the potential benefits and risks of Etodolac and other treatment options before deciding to use Etodolac. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals.

After observing the response to initial therapy with Etodolac, the dose and frequency should be adjusted to suit an individual patient's needs. As with other NSAIDs, the lowest dose and longest dosing interval should be sought for each patient. Therefore, after observing the response to initial therapy with Etodolac, the dose and frequency should be adjusted to suit an individual patient's needs.

Dosage adjustment of Etodolac is generally not required in patients with mild to moderate renal impairment. Etodolac should be used with caution in such patients, because, as with other NSAIDs, it may further decrease renal function in some patients with impaired renal function.


The recommended total daily dose of Etodolac for acute pain is up to 1000 mg, given as 200-400 mg every 6 to 8 hours. Doses of Etodolac greater than 1000 mg/day have not been adequately evaluated in well-controlled clinical trials.

Osteoarthritis and Rheumatoid Arthritis

The recommended starting dose of Etodolac for the management of the signs and symptoms of osteoarthritis or rheumatoid arthritis is: 300 mg b.i.d., t.i.d., or 400 mg b.i.d., or 500 mg b.i.d. A lower dose of 600 mg/day may suffice for long-term administration. Physicians should be aware that doses above 1000 mg/day have not been adequately evaluated in well-controlled clinical trials.

In chronic conditions, a therapeutic response to therapy with Etodolac is sometimes seen within one week of therapy, but most often is observed by two weeks. After a satisfactory response has been achieved, the patient's dose should be reviewed and adjusted as required.

Etodolac interactions

What other drugs will affect Etodolac?


Drug Interactions ACE-inhibitors

Reports suggest that NSAIDs may diminish the antihypertensive effect of ACE-inhibitors. This interaction should be given consideration in patients taking NSAIDs concomitantly with ACE-inhibitors.


The concomitant administration of antacids has no apparent effect on the extent of absorption of Etodolac. However, antacids can decrease the peak concentration reached by 15% to 20% but have no detectable effect on the time-to-peak.


When Etodolac is administered with aspirin, its protein binding is reduced, although the clearance of free Etodolac is not altered. The clinical significance of this interaction is not known; however, as with other NSAIDs, concomitant administration of Etodolac and aspirin is not generally recommended because of the potential of increased adverse effects.

Cyclosporine, Digoxin, Methotrexate

Etodolac, like other NSAIDs, through effects on renal prostaglandins, may cause changes in the elimination of these drugs leading to elevated serum levels of cyclosporine, digoxin, methotrexate, and increase toxicity. Nephrotoxicity associated with cyclosporine may also be enhanced. Patients receiving these drugs who are given Etodolac, or any other NSAID, and particularly those patients with altered renal function, should be observed for the development of the specific toxicities of these drugs. NSAIDs 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 NSAIDs are administered concomitantly with methotrexate.


Etodolac has no apparent pharmacokinetic interaction when administered with furosemide or hydrochlorothiazide. Nevertheless, clinical studies, as well as post marketing observations have shown that Etodolac can reduce the natriuretic effect of furosemide and thiazides in some patients. This response has been attributed to inhibition of renal prostaglandin synthesis. During concomitant therapy with NSAIDs, the patient should be observed closely for sings of renal failure, as well as to assure diuretic efficacy.


Etodolac has no apparent pharmacokinetic interaction when administered with glyburide.


NSAIDs have produced an elevation of plasma lithium levels and a reduction in renal lithium clearance. The mean minimum lithium concentration increased 15% and the renal clearance was decreased by approximately 20%. These effects have been attributed to inhibition of renal prostaglandin synthesis by the NSAID. Thus, when NSAIDs and lithium are administered concurrently, subjects should be observed carefully for signs of lithium toxicity.


Phenylbutazone causes increase (by about 80%) in the free fraction of Etodolac. Although in vivo studies have not been done to see if Etodolac clearance is changed by coadministration of phylbutazone, it is not recommended that they be coadministered.


Etodolac has no apparent pharmacokinetic interaction when administered with phenytoin.


The effects of warfarin and NSAIDs on GI bleeding are synergistic, such that users of both drugs together have a risk of serious GI bleeding higher than that of users of either drug alone. Short-term pharmacokinetic studies have demonstrated that concomitant administration of warfarin and Etodolac results in reduced protein binding of warfarin, but there was no change in the clearance of free warfarin. There was no significant difference in the pharmacodynamic effect of warfarin administered alone and warfarin administered with Etodolac as measured by prothrombin time. Thus, concomitant therapy with warfarin and Etodolac should not require dosage adjustment of either drug. However, caution should be exercised because there have been a few spontaneous reports of prolonged prothrombin times, with or without bleeding, in Etodolac-treated patients receiving concomitant warfarin therapy.

Drug/Laboratory Test Interactions

The urine of patients who take Etodolac can give a false-positive reaction for urinary bilirubin (urobilin) due to the presence of phenolic metabolites of Etodolac. Diagnostic dip-stick methodology, used to detect ketone bodies in urine, has resulted in false-positive findings in some patients treated with Etodolac. Generally, this phenomenon has not been associated with other clinically significant events. No dose relationship has been observed.

Etodolac treatment is associated with a small decrease in serum uric acid levels. In clinical trials, mean decreases of 1 to 2 mg/dL were observed in arthritic patients receiving Etodolac (600 mg to 1000 mg/day) after 4 weeks of therapy. These levels then remained stable for up to 1 year of therapy.

What is the most important information I should know about Etodolac?

This medicine can increase your risk of life-threatening heart or circulation problems, including heart attack or stroke. This risk will increase the longer you use Etodolac. Do not use this medicine just before or after having heart bypass surgery (also called coronary artery bypass graft, or CABG).

Seek emergency medical help if you have symptoms of heart or circulation problems, such as chest pain, weakness, shortness of breath, slurred speech, or problems with vision or balance.

This medicine can also increase your risk of serious effects on the stomach or intestines, including bleeding or perforation (forming of a hole). These conditions can be fatal and gastrointestinal effects can occur without warning at any time while you are taking Etodolac. Older adults may have an even greater risk of these serious gastrointestinal side effects.

Call your doctor at once if you have symptoms of bleeding in your stomach or intestines. This includes black, bloody, or tarry stools, or coughing up blood or vomit that looks like coffee grounds.

Do not use any other over-the-counter cold, allergy, or pain medication without first asking your doctor or pharmacist. Many medicines available over the counter contain aspirin or other medicines similar to Etodolac (such as ibuprofen, ketoprofen, or naproxen). If you take certain products together you may accidentally take too much of this type of medication. Read the label of any other medicine you are using to see if it contains aspirin, ibuprofen, ketoprofen, or naproxen.

Do not drink alcohol while taking Etodolac. Alcohol can increase the risk of stomach bleeding caused by Etodolac.

Avoid exposure to sunlight or artificial UV rays (sunlamps or tanning beds). Etodolac can make your skin more sensitive to sunlight and sunburn may result.
