Always inform your doctor about all medications, supplements, and herbal remedies you take before starting levothyroxine. This includes over-the-counter drugs like antacids and pain relievers.
Certain medications can interfere with levothyroxine absorption. For example, calcium supplements, iron supplements, and some types of antacids can reduce levothyroxine’s effectiveness if taken simultaneously. Space the timing of your levothyroxine intake at least four hours from these medications.
Drugs like cholestyramine and colestipol bind to levothyroxine, preventing its absorption. Your doctor may adjust your levothyroxine dosage if you are also taking these medications.
Some medications, such as certain antidepressants and steroids, can affect your body’s metabolism of levothyroxine, potentially requiring dosage adjustments. Regular monitoring of thyroid hormone levels is important while taking these medications concurrently.
Soy products can also decrease levothyroxine absorption. Consult with your doctor on how to manage your diet while on this medication.
This information does not replace professional medical advice. Always consult your doctor or pharmacist for personalized guidance regarding potential drug interactions and optimal management of your levothyroxine treatment.
