While turmeric is a staple spice in many cuisines and is generally safe in food amounts, its active compound, curcumin, is highly concentrated in supplements. This increased concentration can cause significant interactions with various prescription and over-the-counter medications.
Medications that slow blood clotting
High doses of turmeric can interact with medications that thin the blood, increasing the risk of bleeding or bruising. Curcumin possesses mild anticoagulant and antiplatelet properties.
Anticoagulants (warfarin)
Warfarin (Coumadin), a potent anticoagulant, can have its effects enhanced by high-dose turmeric, increasing the risk of severe bleeding. Close monitoring is needed if combining the two.
Antiplatelet drugs (aspirin, clopidogrel)
These medications prevent platelets from clumping. Combining them with turmeric can raise the risk of bleeding. This includes aspirin.
Diabetes medications
Curcumin may lower blood sugar, which can be a concern for those on diabetes medication.
Insulin and oral hypoglycemics
Taking turmeric supplements with diabetes medications like insulin or glyburide can lead to hypoglycemia. Symptoms include dizziness, shakiness, confusion, and a fast heartbeat. Dosage adjustments of diabetes medication might be needed.
Medications that reduce stomach acid
Turmeric's effect on stomach acid can interfere with acid-reducing medications.
Proton pump inhibitors (PPIs) and H2 blockers
Examples include omeprazole (Prilosec), famotidine (Pepcid), and cimetidine (Tagamet). Turmeric can increase stomach acid, counteracting these drugs and potentially causing stomach discomfort, bloating, or nausea.
Specific chemotherapy drugs
Curcumin can interfere with certain chemotherapy drugs. Consultation with an oncologist is crucial before using supplements.
Drugs like doxorubicin and cyclophosphamide
Turmeric's antioxidant properties might interfere with some chemotherapy drugs' effectiveness, potentially reducing their impact.
Immunosuppressive drugs
Turmeric can affect levels of immunosuppressants, crucial for preventing transplant rejection.
Tacrolimus (Prograf)
Curcumin may increase tacrolimus levels, raising the risk of side effects like kidney damage.

General cautions when taking turmeric supplements
- Iron Supplements: Turmeric may hinder iron absorption; caution is advised for those with iron-deficiency anemia.
- Surgery: Due to blood-thinning effects, stopping turmeric supplements two weeks before surgery may be recommended.
- Liver Disease: High doses may rarely cause liver damage; caution is needed for individuals with liver disease.
- Pregnancy and Breastfeeding: Safety of high-dose supplements during these periods is not established.

Conclusion
While adding turmeric as a seasoning to your meals is generally safe, taking concentrated supplements introduces a higher risk of drug interactions. It is essential to have an open and honest conversation with a healthcare provider before starting any new supplement regimen to ensure it does not negatively interfere with your current medications or health conditions.
