Etodolac is a prescription only non-steroidal anti-inflammatory drug (NSAID) used as a long-term treatment for arthritis. It can also be used short-term to relieve acute pain.

Once available in the brand name form of Lodine, etodolac is now only available in its generic form. Etodolac comes in three forms—tablet, capsule, and extended-release tablet.

To treat arthritis, the tablet and capsule are usually taken by mouth two to three times a day. The extended-release tablet is usually taken once a day. When taking etodolac for acute (sudden) or severe pain from causes other than arthritis, you will typically take the tablets or capsules every six to eight hours.

When you first begin this medication, your doctor may start you on a high dose and decrease your dose once your symptoms are controlled. This may take a couple of weeks.

If you have been prescribed etodolac for arthritis or other pain syndromes, it is important to follow all directions on your prescription label and to take this medicine as directed.

All medicines carry the possibility of reacting with other drugs or substances which is why it’s important to inform your medical team of everything you take—prescription, supplemental, and over the counter. Etodolac has a known list of drugs that it interacts with to varying degrees of severity.

Before beginning any new drug, it is important to let your doctor and pharmacist know what medicines—prescription and over the counter—you currently take. Mixing different drugs can cause serious side effects. Your doctor and pharmacist should be aware of all your medicines to prevent any interactions.
