Hypothyroidism - American Thyroid Association
... You’ll need to have your TSH checked about every 6 to 10 weeks after a thyroxine dose change. You may need tests more often if you’re pregnant or you’re taking a medicine that interferes with your body’s ability to use thyroxine. The goal of treatment is to get and keep your TSH in the normal range. ...
