Drug Interactions
Your doctor or pharmacist may already be aware of any possible drug interactions and may be monitoring you for them. Do not start, stop, or change the dosage of any medicine before checking with your doctor or pharmacist first. Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of: androgens/anabolic steroids, beta blockers (e.g., propranolol), "blood thinners" (e.g., warfarin), corticosteroids (e.g., dexamethasone), cytokines (e.g., interferon-alpha, interleukin-2), diabetes medications (e.g., insulin, sulfonylureas such as glyburide/glipizide), digoxin, drugs affecting liver enzymes that remove liotrix from your body (such as phenobarbital, rifamycins including rifabutin, certain anti-seizure medicines including carbamazepine/phenytoin), drugs that can decrease thyroid hormone levels (e.g., amiodarone, medications containing iodide/iodine, lithium), estrogen-containing products (including birth control pills), growth hormones, medications for depression (e.g., maprotiline, tricyclic antidepressants such as amitriptyline, SSRIs such as sertraline), theophylline. Certain medications (cholestyramine, colestipol, antacids, sucralfate, simethicone, iron, sodium polystyrene sulfonate, calcium carbonate, orlistat) can decrease the amount of liotrix that is absorbed by your body . If you are taking any of these drugs, separate them from this medication by at least 4 hours. Check the labels on all your medicines (e.g., cough-and-cold products, diet aids) because they may contain ingredients such as decongestants or caffeine that could increase your heart rate or blood pressure. Ask your pharmacist about using those products safely. This document does not contain all possible interactions. Therefore, before using this product, tell your doctor or pharmacist of all the products you use. Keep a list of all your medications with you, and share the list with your doctor and pharmacist.
