BP Tertroxin 25 contains liothyronine sodium 25mcg, which is a naturally occurring thyroid hormone.
Users take liothyronine sodium for its ability to increase metabolism and support the breakdown of body fat.
The principal pharmacological effect of exogenous thyroid hormones is to increase the metabolic rate of body tissues. The biological action of liothyronine sodium is qualitatively similar to that of thyroxine but the effect develops in a few hours and disappears within 24-48 hours of stopping treatment.
Normal Tertroxin dosages vary from one individual to the next. Anything from 25-100mcg per day can be used, but it should be individually determined by starting on 25mcg and increasing with 12.5mcg every three or four days (half a tablet).
The intent of this slow buildup is to help the body become adjust to the increasing thyroid hormone levels, and avoid sudden changes that may initiate side effects. Cycles of liothyronine sodium usually last no longer than 6 weeks, and administration of the drug should not be halted abruptly. Instead, it is discontinued in the same slow manner in which it was initiated. This usually entails reducing the dosage by 10mcg every three to four days. This tapering is done so that the body has time to readjust its endogenous hormone production at the conclusion of therapy.
