A friend tells me that he’s been diagnosed with hypothyroidism (TSH 7.5) and he’s starting on Synthroid (Levothyroxine). Google takes me to the NIH page on Levothyroxine. Right at the top is the following offset warning:
Thyroid hormone should not be used to treat obesity in patients with normal thyroid function. Levothyroxine is ineffective for weight reduction in normal thyroid patients and may cause serious or life-threatening toxicity, especially when taken with amphetamines. Talk to your doctor about the potential risks associated with this medication.
I know there are people who do risky things to lose weight. (Less than 600 calories a day, anyone? I’ve done it.) But … hello?
