TIRATRICOL: Overview, Uses, Side Effects, Precautions, Interactions, Dosing and Reviews

Overview

Tiratricol is a naturally occurring chemical in the body. It can also be man-made.

Tiratricol is taken by mouth under the supervision of a healthcare provider for the treatment of thyroid problems including thyroid cancer and underactive thyroid (hypothyroidism). Some people take tiratricol to lose weight, but there is no good scientific research to support this use.

In the US, between 1999 and 2001, the Food and Drug Administration (FDA) required several tiratricol-containing products to be recalled, and obtained a court order to prevent companies from marketing them. The FDA determined that tiratricol is not a dietary supplement but an unapproved new drug containing a powerful thyroid hormone, which may cause serious health consequences.

In France, tiratricol is a prescription drug used mostly for thyroid disease. It has been studied in France since the 1950s.

How does it work ?

Tiratricol seems to work by altering thyroid function.

Interactions ?

Major Interaction

Do not take this combination

Stimulant drugs interacts with TIRATRICOL
Stimulant drugs speed up the nervous system. By speeding up the nervous system, stimulant medications can make you feel jittery and speed up your heartbeat. Tiratricol might also speed up the nervous system. Taking tiratricol along with stimulant drugs might cause serious problems including increased heart rate and high blood pressure. Avoid taking stimulant drugs along with tiratricol.
Some stimulant drugs include diethylpropion (Tenuate), epinephrine, phentermine (Ionamin), pseudoephedrine (Sudafed), and many others.
Thyroid hormone interacts with TIRATRICOL
Tiratricol works similarly to thyroid hormones. Taking tiratricol along with thyroid hormone pills might increase the chance of side effects from thyroid hormone.

Moderate Interaction

Be cautious with this combination

Cholestyramine (Questran) interacts with TIRATRICOL
Cholestyramine (Questran) might decrease how much tiratricol the body absorbs. By decreasing how much tiratricol the body absorbs, cholestyramine (Questran) might decrease the effectiveness of tiratricol supplements. To avoid this interaction take tiratricol at least one hour before or four hours after taking cholestyramine.
Medications that slow blood clotting (Anticoagulant / Antiplatelet drugs) interacts with TIRATRICOL
Tiratricol might slow blood clotting. Taking tiratricol along with medications that also slow clotting might increase the chances of bruising and bleeding.
Some medications that slow blood clotting include aspirin, clopidogrel (Plavix), diclofenac (Voltaren, Cataflam, others), ibuprofen (Advil, Motrin, others), naproxen (Anaprox, Naprosyn, others), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, warfarin (Coumadin), and others.
Medications for diabetes (Antidiabetes drugs) interacts with TIRATRICOL
Large amounts of tiratricol can decrease blood sugar levels. Diabetes medications are also used to lower blood sugar. Taking tiratricol along with diabetes medications might cause your blood sugar to be too low. Monitor your blood sugar closely. The dose of your diabetes medication might need to be changed.
Some medications used for diabetes include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), chlorpropamide (Diabinese), glipizide (Glucotrol), tolbutamide (Orinase), and others.
