Levothyroxine is in micrograms, hence 70 micrograms will be 0.07 mg. TSH is low that indicates that thyroid hormone replacement is adequate to high. please check level of T3 and T4 with TSH and see your endocrinologist for adjustment if needed. Please refrain from adjusting levothyroxine dosage by yourself. Hope it helps.

No hurry, Wait till Dr gets back. Be certain you are taking on empty stomach. Go to Drugs.com and read about how to take thyroid meds.
