Can I take two Thyronorm 50 instead of one Thyronorm 100?
Two 50 mcg tablets equal 100 mcg, so in a pinch that is the same dose – but only if 100 mcg is what your doctor prescribed. Do not change your thyroid dose without a TSH test.
How does the doctor choose 50 or 100?
By your TSH level, weight, age and heart health. Many start at 25–50 mcg and step up; a full replacement dose for an adult is often around 100 mcg or more.
What happens if I take too much?
Palpitations, sweating, weight loss, shakiness and poor sleep – signs of an overactive thyroid. Too little causes tiredness, weight gain and feeling cold. Both are corrected by dose adjustment.
How should I take either strength?
On an empty stomach, 30–60 minutes before breakfast, at the same time every day, with water. Keep calcium, iron and antacids at least 4 hours apart.
