Etodolac is contraindicated in patients with known hypersensitivity to Etodolac. Etodolac should not be given to patients who have experienced asthma, urticaria or other allergic type reactions after taking Aspirin or other NSAIDs.

Similar to other NSAIDs, the anti-inflammatory effects of etodolac result from inhibition of the enzyme cycooxygenase (COX). This decreases the synthesis of peripheral prostaglandins involved in mediating inflammation. Etodolac binds to the upper portion of the COX enzyme active site and prevents its substrate, arachidonic acid, from entering the active site. Etodolac was previously thought to be a non-selective COX inhibitor, but it is now known to be 5-50 times more selective for COX-2 than COX-1. Antipyresis may occur by central action on the hypothalamus, resulting in peripheral dilation, increased cutaneous blood flow, and subsequent heat loss.

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. 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.

The common side effects of Etodolac involve the gastrointestinal system. It can cause abdominal pain, constipation, diarrhea, dyspepsia, flatulence, heartburn, nausea, Gl ulcers, vomiting. Other events including abnormal renal function, anemia, dizziness, edema, elevated liver enzymes, headaches, increased bleeding time, pruritis, rashes, tinnitus etc.

Symptoms following acute NSAID overdose are usually limited to lethargy, drowsiness, nausea, vomiting, and epigastric pain which are generally reversible with supportive care.

There are no adequate and well-controlled studies in pregnant women. It should be used in pregnancy only if the potential benefit justifies the potential risk to the fetus. It is not known whether Etodolac is excreted in human milk. A decision should be made whether to discontinue nursing or to discontinue the drug taking into account the importance of the drug to the mother.

Etodolac should be given with caution in patients with severe hepatic reactions, pre existing asthma, fluid retention, hypertension or heart failure. If clinical sings and symptoms consistent with liver disease develop, or if systemic manifestations occur (e.g. eosinophilia, rash etc.), it should be discontinued.
