Sulindac is used to treat rheumatoid arthritis, osteoarthritis and ankylosing spondylitis, a rheumatic disorder involving the spine and large joints. It also treats both acute painful shoulder and gouty arthritis. Sulindac is in a class of medications known as non-steroidal anti-inflammatory drugs (NSAIDs).
Common brand names:Clinoril
Summary of Interactions with Vitamins, Herbs, & Foods
Replenish Depleted Nutrients
NSAIDs cause gastrointestinal (GI) irritation, bleeding, and iron loss. Iron supplements can cause GI irritation. However, iron supplementation is sometimes needed in people taking NSAIDs if those drugs have caused enough blood loss to lead to iron deficiency. If both iron and nabumetone are prescribed, they should be taken with food to reduce GI irritation and bleeding risk.
Reduce Side Effects
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. DGL has been shown in controlled human research to be as effective as drug therapy (cimetidine) in healing stomach ulcers.
In a controlled human study, people who took stinging nettle with diclofenac obtained similar pain relief compared to people taking twice as much diclofenac with no stinging nettle. More research is needed to determine whether people taking diclofenac might benefit from also taking stinging nettle.
Potential Negative Interaction
Four people who took sulindac developed high blood levels of potassium, which returned to normal within a few days after the drug was stopped. Controlled research is needed to determine whether potassium supplements or a high potassium diet might aggravate this problem. Until more information is available, people taking sulindac and potassium supplements, potassium containing salt substitutes, or large amounts of fruits and vegetables should have potassium blood levels checked regularly by their doctor.The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
White willow bark contains salicin, which is related to 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. 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.
Sulindac blocks the activity of enzymes that depend on folic acid and may, like aspirin, reduce the amount of folic acid in red blood cells. Further research is needed to determine whether supplementing folic acid changes the effects of sulindac therapy or prevents a deficiency of this vitamin in the body.The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
