Can starting a low dose of Thyronorm (50mcg) for an underactive thyroid cause noticeable hair loss, and is this a common side effect or a sign of an allergic reaction?
Starting Thyronorm (levothyroxine) can sometimes cause temporary hair shedding during the first few weeks of treatment. This is a known, temporary response as your body adjusts to the corrected thyroid hormone levels, and it is not a sign of an allergic reaction. A true allergic reaction would typically involve hives, itching, or swelling. Please be reassured that this shedding is usually temporary, and your hair should regrow normally once your hormone levels stabilize.
