One more query we ran across in our research was “What dosages are available for levothyroxine?”.
The dose of levothyroxine will be different for different people. Your doctor will usually start you on a low dose and increase the dose depending on how you respond. The usual starting dose is 50–100 micrograms daily, which may be increased slowly to 100–200 micrograms daily. Levothyroxine is usually taken once a day., and more items.
Brand and Other Names: Synthroid, Levoxyl, more 1.7 mcg/kg or 100-125 mcg PO q. Day; not to exceed 300 mcg/day If replacement therapy not initiated, monitor patient annually for clinical status.
How much Levothyroxine should I take for hypothyroidism?
For oral dosage form (tablet): For hypothyroidism: Adults and children older than 12 years of age (growth and puberty complete)—Dose is based on body weight and must be determined by your doctor. The dose is usually 1.6 microgram (mcg) per kilogram (kg) of body weight per day but may be less in older adults.
How many MCG of Levothyroxine should I take?
Individuals over 50 years and/or Patients with Cardiovascular Disease: Initial dose: 12.5 to 25 mcg orally once a day. -Adjust dose at 6 to 8-weeks intervals until clinically euthyroid and TSH returns to normal.
Primary Hypothyroidism: For otherwise healthy individuals in whom growth and puberty are complete: Initial dose: 1.6 mcg/kg orally once a day -Adjust dose in 12.5 to 25 mcg increments every 4 to 6 weeks until clinically euthyroid and TSH returns to normal Individuals over 50 years and/or Patients with Cardiovascular Disease:.
One way to think about this is mild Hypothyroidism 1 Usual initial drug dose: 12.5-25 mcg PO q, and day. 2 May adjust drug dose by 12.5-25 mcg q4-6weeks until patient becomes euthyroid and serum TSH concentration normalized; adjustments q6-8weeks also used. 3 Dose range: 100-125 mcg PO q, and day.
What is the recommended starting dose of levothyroxine sodium for infants?
The recommended starting dose of levothyroxine sodium in newborn infants is 10-15 mcg/kg/day. A lower starting dose (e. g, 25 mcg/day) should be considered in infants at risk for cardiac failure, and the dose should be increased in 4-6 weeks as needed based on clinical and laboratory response to treatment.
This of course begs the inquiry “When should I start levothyroxine sodium tablets?”
Start levothyroxine sodium tablets at the full replacement dose in otherwise healthy, non-elderly individuals who have been hypothyroid for only a short time (such as a few months). The average full replacement dose of levothyroxine sodium tablets is approximately 1.6 mcg per kg per day (for example: 100 to 125 mcg per day for a 70 kg adult).
