Question 2

what are the tests for synthroid (thyroxine) overdose?

Accepted Answer

Tsh,T3, T4, symptoms: Blood tests can determine overdose. Symptoms of excessive thyroid intake include anxiety, heart racing, headaches, hair shedding, shortness of breath, muscle weakness, overactive bowel function (i.e. Frequent bms, loos stools), possibly elevated temperature, weight loss, high blood pressure. Over long period of time, eyes will start to protrude.

Question 3

what is the definition or description of: thyroxine overdose?

Accepted Answer

Taking too much: The definition of a drug overdose (legal or illegal) of any kind is simply taking too much of a substance than is recommended. Technically the FDA adds the most important part: at amounts sufficient to possibly cause or that causes an adverse event or side effect. You can overdose on an accepted amount if it right too much for you, someone on 25 mcg thyroxine who takes 2 technically overdosed.

Question 4

what is the definition or description of: synthroid (thyroxine) overdose?

Accepted Answer

Synthroid: Synthroid (levothyroxine) overreplacement causes subclinical hyperthyroidism (normal serum T4 and T3 and low serum TSH concentrations) or even overt hyperthyroidism. The main risks are arrhythmia and accelerated bone loss/fractures, especially in older patients. Maintenance dose should be adjusted appropriately by a physician.

Question 5

what is the treatment for thyroxine overdose?

Accepted Answer

It depends: If severe, too much thyroid hormone in the blood can cause organs to stop working properly, a condition known as thyroid storm, and treatment in a hospital ICU may be needed.  For less severe cases, treatment with beta-blockers (bp meds) may lessen symptoms of palpitations, shakiness, and jitters.  For mild cases, no treatment may be needed at all.

Question 6

what is the treatment for synthroid (thyroxine) overdose?

Accepted Answer

Supportive: Usually overdose does not cause problems.  In a massive overdose, an epinephrine-blocker such as Propranolol may be lifesaving, and monitoring and managing the heart rhythm disturbances that may occur is critical.

Not in USA: Levothyroxine in the usa is available as 25, 50, 75, 88, 100, 112, 125, 137, 150, 175, 200, 300 mcg.  There is no 37.5 mcg dose available.  However, you could take 1/2 of a 75 mcg if you like, or take 75 mcg every other day.  The result would be the same.  I don't know about the availability is in the uk.
