Sulindac
Before using Sulindac, patients must consult their healthcare provider, particularly in the following situations:
- Allergies: Sulindac is an NSAID (Nonsteroidal Anti-Inflammatory Drug), and people with a history of allergic reactions to NSAIDs, including aspirin, should avoid its use. This includes individuals who have experienced asthma, angioedema, or urticaria after taking aspirin or other NSAIDs.
- Gastrointestinal Conditions: Sulindac can cause gastric irritation, ulcers, or bleeding. Patients with a history of gastrointestinal diseases (such as peptic ulcers, Crohn's disease, or ulcerative colitis) should use Sulindac cautiously, as it may worsen these conditions.
- Renal or Liver Disease: Sulindac is metabolized by the liver and eliminated by the kidneys, so it should be used with caution in patients with renal or hepatic impairment. Kidney function should be closely monitored, especially in elderly patients or those with pre-existing conditions.
- Heart Disease: Long-term use of NSAIDs, including sulindac, may increase the risk of cardiovascular events such as heart attack, stroke, and heart failure, particularly in individuals with pre-existing cardiovascular conditions or those taking diuretics, ACE inhibitors, or angiotensin receptor blockers.
- Pregnancy and Lactation: Sulindac is generally contraindicated during the third trimester of pregnancy, as it may affect fetal circulation and cause premature closure of the ductus arteriosus. It should only be used during pregnancy if absolutely necessary, under the guidance of a healthcare provider. Sulindac also passes into breast milk, so nursing mothers should consult a doctor before use.
Sulindac is primarily used to treat conditions associated with inflammation and pain, including:
- Osteoarthritis: Sulindac is often prescribed to relieve the pain and inflammation associated with osteoarthritis. It helps reduce joint swelling, discomfort, and stiffness.
- Rheumatoid Arthritis: It is also indicated for the management of rheumatoid arthritis, a chronic inflammatory condition affecting the joints.
- Acute Gouty Arthritis: Sulindac is used to treat the acute flare-ups of gout, a condition characterized by sudden and severe pain, usually in the joints.
- Ankylosing Spondylitis: This drug is effective in treating ankylosing spondylitis, a condition causing inflammation in the spine.
- Other Off-Label Uses: Sulindac may be used off-label for conditions such as tendinitis, bursitis, and other musculoskeletal disorders, where inflammation and pain are prominent symptoms.
Sulindac is contraindicated in several situations, including:
- Active Peptic Ulcer Disease: Due to its potential to cause gastric irritation, ulceration, and bleeding, Sulindac should not be used in patients with active peptic ulcers or a history of gastric bleeding.
- Severe Liver Dysfunction: Sulindac is contraindicated in patients with severe hepatic impairment, as the drug is metabolized by the liver and could accumulate to toxic levels.
- Severe Renal Impairment: Patients with severe renal impairment or end-stage kidney disease should not take Sulindac, as it can exacerbate renal dysfunction.
- Hypersensitivity: Sulindac is contraindicated in patients with known hypersensitivity or allergic reactions to sulfonamides or other NSAIDs.
- Third-Trimester of Pregnancy: Due to the risk of premature closure of the ductus arteriosus and other fetal complications, Sulindac is contraindicated during the third trimester of pregnancy.
Sulindac, like other NSAIDs, can cause a range of side effects. Some common and serious effects include:
- Common Side Effects:
- Gastrointestinal issues: Nausea, indigestion, dyspepsia, and gastric pain are common, especially if taken on an empty stomach.
- Headaches: Some patients report experiencing headaches while taking sulindac.
- Dizziness and Drowsiness: These side effects can occur, especially when standing up quickly or during prolonged use.
- Rashes: Skin rashes may develop in some individuals.
- Serious Side Effects:
- Gastrointestinal Bleeding: NSAIDs can increase the risk of gastric ulcers, bleeding, and perforation, especially in older adults or those with a history of ulcers.
- Cardiovascular Events: Sulindac may increase the risk of heart attack, stroke, and heart failure, particularly with long-term use.
- Kidney Damage: Prolonged use of Sulindac can result in renal toxicity or acute kidney injury, particularly in individuals with pre-existing kidney problems.
- Liver Damage: Sulindac can cause liver enzyme elevation and, in rare cases, liver failure. Monitoring liver function is recommended during treatment.
- Severe Allergic Reactions: In rare cases, sulindac may cause anaphylaxis, angioedema, or other severe allergic reactions, necessitating immediate medical attention.

Sulindac belongs to the class of NSAIDs, and its primary mode of action is based on the inhibition of cyclooxygenase (COX) enzymes, which play a key role in the production of prostaglandins:
- Inhibition of COX Enzymes: Sulindac inhibits COX-1 and COX-2 enzymes, which are responsible for the conversion of arachidonic acid into prostaglandins.
- Reduction of Prostaglandins: By blocking COX enzymes, sulindac reduces the synthesis of prostaglandins, which are compounds involved in inflammation, pain, and fever.
- Anti-inflammatory and Analgesic Effects: The reduction in prostaglandin production results in the alleviation of pain, swelling, and fever, making Sulindac effective in treating inflammatory conditions like arthritis and gout.
Sulindac may interact with various medications, affecting the drug’s action or the effectiveness of other treatments:
- Anticoagulants (e.g., Warfarin): NSAIDs, including Sulindac, can increase the risk of bleeding when used in combination with anticoagulants like warfarin. Monitoring of INR levels is recommended.
- Diuretics and Antihypertensive Drugs: Sulindac may reduce the effectiveness of diuretics (e.g., furosemide) and ACE inhibitors, as it can impair renal function, leading to elevated blood pressure.
- Lithium: Sulindac may increase lithium levels, leading to toxicity. Blood lithium levels should be monitored in patients taking both drugs.
- Methotrexate: Sulindac may increase methotrexate toxicity, particularly at higher doses. Caution is advised when combining these drugs.
- Corticosteroids: Using Sulindac in conjunction with steroids may increase the risk of gastrointestinal bleeding or ulceration.
- Aspirin: Sulindac should be used with caution when taken with aspirin, as the combination may increase the risk of gastrointestinal side effects, such as ulcers and bleeding.
Pregnancy Category: C; D in 3rd trimester.
The typical dosage for adults varies based on the condition being treated:
- Osteoarthritis and Rheumatoid Arthritis: The recommended dose is 150 mg per day, taken in divided doses (e.g., 75 mg twice daily). The dose can be increased to 200 mg per day if necessary.
- Acute Gouty Arthritis: For acute gout attacks, Sulindac is often given as 200 mg twice a day for 7-14 days until symptoms resolve.
- Ankylosing Spondylitis: The dose typically starts at 150 mg per day, taken in divided doses, and can be increased as needed to control symptoms.
Sulindac is generally not recommended for children under 14 years of age, as its safety and efficacy in pediatric populations have not been well established. For older children, the dose would be determined based on weight, and should be done under a healthcare provider’s guidance.
Consulting with a healthcare provider before starting Sulindac is crucial to ensure it is appropriate for your condition, and to receive proper guidance on dosing, potential side effects, and interactions with other medications.
Sulindac should be used with caution in individuals with renal impairment. In patients with mild renal dysfunction, the dose may remain the same, but monitoring renal function is essential. In cases of severe renal impairment, sulindac should be avoided or given at a reduced dose, with careful monitoring of kidney function throughout treatment.
