Dosing medication for hypothyroidism

Dosing Thyroid Medications

The most common problem I see with patients on thyroid medication for hypothyroidism is how the medication is dosed. The symptoms of hypothyroidism are due to fluctuations in blood/tissue thyroid levels, rather than absolute levels. Therefore, dosing the medication properly becomes very important to keep blood levels consistent and smooth. Remember: do not change what you are doing until you talk to your prescribing doctor since it can greatly change the amount of thyroid medication absorbed into you system

30 MINUTE RULE :
in the morning on an empty stomach, wait at least 30 minutes before eating food in general.
WEEKLY RULE :
If you forget/miss a dose, don't take it in the middle of the day. Take your regular dose the next morning plus the dose you missed from the previous day. Don't make this a habit. The weekly dose of T4 matters more than the daily dosage. This does not apply to non-T4 medications for hypothyroidism
4-HOUR RULE :
These medications/foods completely prevent the absorption of thyroid medication and should be separated by at least 4 hours (four hours prior and 4 hours after dosing thyroid medication): Any Vitamin pill, Any Supplement pill, Any Stomach medication, Calcium tablets / iron tablets /Soy products/ pepto bismol/ any vitamin / laxatives / prunes / walnuts.

Note: if you are taking T3 (liothyronine or cytomel) it is shorter acting than T4 so do not double dose (weekly dose rule does not apply), if dose missed then just take when you remember. Take it as directed
*If you develop chest pains, palpitations, shortness of breath while taking this medication please call our office.
*If you take the generic form (levothyroxine) please only refill the prescription at that exact same pharmacy location each time in order to get consistent drug levels
* If you take a supplement called BIOTIN, please stop this medication 5 days prior to your thyroid blood testing as it can affect the thyroid blood levels.
--WOMEN: if you are PREGNANT - thyroid dosing changes a lot during pregnancy.
