Drug & Food Interactions of Euthyrox 50mcg Tablet

Drug Interactions:

• Antacids, calcium supplements, and iron supplements — can reduce the absorption of Levothyroxine; take Euthyrox at least 2 to 4 hours apart from these products
• Cholestyramine and colestipol (cholesterol-lowering medicines) — may decrease Levothyroxine absorption
• Warfarin and other anticoagulants — Levothyroxine may enhance the blood-thinning effect, requiring close monitoring
• Antidiabetic drugs (insulin or oral hypoglycaemics) — thyroid hormone replacement may alter blood sugar levels, requiring dose adjustments
• Antidepressants (e.g., sertraline, amitriptyline) — may affect Levothyroxine levels or increase the risk of side effects
• Certain seizure medications (e.g., phenytoin, carbamazepine) — may reduce Levothyroxine levels in the blood
• Rifampicin — may accelerate the breakdown of Levothyroxine, reducing its effectiveness
• Proton pump inhibitors (e.g., omeprazole) — may reduce absorption of Levothyroxine

Food Interactions:

• Soy-based foods and soy milk — may interfere with Levothyroxine absorption; avoid consuming around the time of your dose
• High-fibre foods (in very large quantities) — may reduce absorption if consumed immediately with the tablet
• Grapefruit juice — some evidence suggests it may slightly delay absorption; best avoided around dosing time
• Coffee — avoid taking Euthyrox with coffee, as it can significantly reduce absorption; always take with plain water

💡 Always inform your doctor and pharmacist about all medicines, supplements, and herbal products you are currently taking to avoid potential interactions.
