Etodolac

Drug Information

Etodolac is a member of the non-steroidal anti-inflammatory drug (NSAIDs) family. NSAIDs reduce inflammation (swelling), pain, and temperature. Etodolac is used to treat mild to moderate pain, Reference osteoarthritis, Reference rheumatoid arthritis, ankylosing spondylitis, tendinitis, Reference bursitis, and other conditions.

Lodine, Lodine XL

Summary of Interactions with Vitamins, Herbs, & Foods

Reference What Are Nutrient Interactions

Types of interactions: Beneficial Adverse Check

Replenish Depleted Nutrients

Reference Iron

NSAIDs cause gastrointestinal (GI) irritation, bleeding, and iron loss.¹ Iron supplements can cause GI irritation.² However, iron supplementation is sometimes needed in people taking NSAIDs if those drugs have caused enough blood loss to lead to Reference iron deficiency. If both iron and etodolac are prescribed, they should be taken with food to reduce GI irritation and bleeding risk.

Reduce Side Effects

Reference Licorice

The flavonoids found in the extract of licorice (Glycyrrhiza glabra) known as DGL (deglycyrrhizinated licorice) are helpful for avoiding the irritating actions NSAIDs have on the stomach and intestines. One study found that 350 mg of chewable DGL taken together with each dose of aspirin reduced gastrointestinal bleeding caused by the aspirin.³ DGL has been shown in controlled human research to be as effective as drug therapy (Reference cimetidine) in healing stomach Reference ulcers.⁴

Potential Negative Interaction

Sodium

Etodolac may cause sodium and Reference water retention.⁵ It is healthful to reduce dietary salt intake by eliminating table salt and heavily salted foods.

The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
Reference White Willow

White willow bark (Salix alba) contains salicin, which is related to Reference aspirin. Both salicin and aspirin produce anti-inflammatory effects after they have been converted to salicylic acid in the body. The administration of salicylates like aspirin to individuals taking oral NSAIDs may result in reduced blood levels of NSAIDs.⁶ Though no studies have investigated interactions between white willow bark and NSAIDs, people taking NSAIDs should avoid the herb until more information is available.

The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.

Explanation Required

Reference Potassium

NSAIDs have caused kidney dysfunction and increased blood potassium levels, especially in older people.⁷ People taking NSAIDs, including etodolac, should not supplement potassium without consulting with their doctor.
Reference Copper

Supplementation may enhance the anti-inflammatory effects of NSAIDs while reducing their Reference ulcerogenic effects. One study found that when various anti-inflammatory drugs were chelated with copper, the anti-inflammatory activity was increased.⁸ Animal models of inflammation have found that the copper chelate of Reference aspirin was active at one-eighth the effective amount of aspirin. These copper complexes are less toxic than the parent compounds, as well.

The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.

The Drug-Nutrient Interactions table may not include every possible interaction. Taking medicines with meals, on an empty stomach, or with alcohol may influence their effects. For details, refer to the manufacturers’ package information as these are not covered in this table. If you take medications, always discuss the potential risks and benefits of adding a new supplement with your doctor or pharmacist.
