How this service works
Adult levothyroxine (LT4) full-replacement estimate: daily_lt4_mcg = weight_kg * 1.6 (ATA 2014). Weight in kg or lb. Not a prescription, TSH titration, pediatric or pregnancy-specific dose, or tablet strength. Lean-body-mass adjustment may apply; elderly and cardiac patients often start lower. Deterministic published arithmetic with citation.
Output
Returns the estimated full-replacement levothyroxine daily dose in micrograms, computed as weight_kg × 1.6 per the ATA 2014 guideline. Includes the citation and notes that this is not a prescription, does not account for TSH titration, lean body mass adjustment, pediatric or pregnancy-specific dosing, or tablet rounding.
Example use cases
Full replacement dose for post-thyroidectomy patient
“My patient just had a total thyroidectomy and weighs 68 kg — what's the estimated full-replacement levothyroxine dose per the ATA 2014 guideline?”
LT4 dose estimate using pounds
“Can you calculate the full-replacement levothyroxine daily dose for a 185-pound adult using the standard weight-based formula?”
Cross-check clinical dosing arithmetic
“I want to verify the levothyroxine full-replacement dose for an 80 kg hypothyroid adult — use the ATA 2014 1.6 mcg/kg formula and tell me the result in micrograms.”

Endpoint
GEThttps://api.magentlab.com/api/calc/levothyroxine_doseWhen to prefer
Choose this endpoint when you need a quick, deterministic, evidence-based levothyroxine full-replacement estimate grounded in the published ATA 2014 arithmetic (1.6 mcg/kg). Prefer it over general LLM reasoning when reproducibility and citation traceability matter. Not suitable for titration-based dosing, pediatric patients, pregnancy, or when lean body mass adjustment is required.
Side effects
- Weight out of accepted range (weight_kg < 1 or > 500; weight_lb < 2 or > 1100) returns validation error
- Neither weight_kg nor weight_lb provided returns missing parameter error
- Non-numeric weight value returns type error
- Payment not included or insufficient USDC results in 402 payment required
