Lodine (etodolac) is a nonsteroidal ant-inflammatory drug (NSAID) used to treat osteoarthritis, rheumatoid arthritis, and acute pain. The brand name Lodine is no longer available in the U.S.; Lodine is available as a generic named etodolac. Common side effects of Lodine include vomiting, diarrhea, constipation, upset stomach, stomach pain, heartburn, bloating, gas, headache, dizziness, nervousness, sore throat, stuffy nose, skin itching, rash, blurred vision, and ringing in the ears.

Lodine is available in capsules at strengths of 200 and 300 mg, and as tablets at strengths of 400 and 500 mg. Usual dosage is 200-400 mg every 6 to 8 hours, not to exceed 1000 mg. Serious side effects of Lodine may include heart attack, stroke, coma, skin changes (paleness, blisters, rash, and hives), weight gain, swelling, shortness of breath, tachycardia, unusual bleeding (including GI bleeding), jaundice, stomach pain, and pain with urination, bloody urine, blurry vision, and back pain. Patients with asthma that are aspirin-sensitive should avoid use of this Lodine. Lodine may reduce the effectiveness of ACE inhibitors and increase lithium (Eskalith, Lithobid) levels; use with aspirin or similar agents is not recommended. Caution is advised as Lodine may react with a number of other drugs so the prescribing physician will need a list of current medications. Lodine should be used in pregnancy only if the potential benefit justifies the potential risk to the fetus. It is not known whether Lodine is excreted in human milk. Safety and effectiveness in pediatric patients below the age of 18 years have not been established for Lodine.

Our Lodine Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
