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), 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.
