A 62 - year - sometime humankind ended up in the emergency elbow room with bridge player microseism and center quivering six months after he began get the weight - departure drug tirzepatide , also known as Zepbound . According to his doctors , the man ’s heart predicament was likely triggered by an overdose of his thyroid medicinal drug that was n’t adjusted the right way follow his rapid weightiness expiration from tirzepatide .
Tirzepatide is the latestincretinmedication , a class of drugs that mimics gut and mind hormones important to regulating hunger and metabolism . It ’s the first approve incretin to fuse two of these hormones at once , GLP-1 and GIP — a three-fold - action mechanism that wee-wee it more potent at treating fleshiness and high ancestry sugar . In clinical trials , people have lose an average 20 % or more of their baseline weight , well above the typical success see with diet and exercise alone . These final result have also surpassed the ordinary 15 % weight loss seen with Novo Nordisk ’s semaglutide ( sold under the names Ozempic and Wegovy ) , the first of this newer generation of incretin drugs . Tirzepatide is sold under the name Mounjaro to treat type 2 diabetes and as Zepbound to handle fleshiness . But in this particular case , publishedMonday in the diary JAMA Internal Medicine , the drug ’s effectivity bet to have been an double - edged brand .
According to the report , the homo visit an emergency brake department complaining of palpitation , exuberant sweating , mix-up , fever , and hand tremors . Testing presently revealed that he had develop an atrial fibrillation , or an unorthodox pulsation . The man had a history of type 1 diabetes , obesity , and autoimmune hypothyroidism , the latter being a status where the immune system attacks the thyroid , which then leads to a constant shortage of essential thyroid hormone . He had long been taking insulin for his diabetes and the drug levothyroxine for his hypothyroidism , but six months before his ER visit , he was also start up on tirzepatide for his weighting . The man was around 290 pounds before call for tirzepatide , and he lost more than 80 pounds in half a year .

regrettably , the dosage of levothyroxine take to mimic a sizeable thyroid gland can be affected by lots of things , including eubstance weight . And the man ’s weightiness loss intend that he was now taking too much levothyroxine . His atrial fibrillation and resulting symptom were formally determined to be do by an outpouring of thyroid internal secretion ( formally called hyperthyroidism ) in “ the context of rapid weight expiration from tirzepatide . ” gratefully , he received immediate treatment for his condition in the pinch section .
Other research has loosely institute that incretin drugs may have even more wellness benefit than presently retrieve . A study this Februaryfoundthat tirzepatide can help keep descent pressure in check , while another field of study in Aprilindicatedthat it could be used to treat quietus apnea . But the man ’s Doctor of the Church say this case should render a “ teachable moment”—the object lesson being that every drug , no matter how utile , can have risks that should be proactively monitored by clinician . For situations like this , doctors should look at check and readjusting people ’s levothyroxine dosage every 4 to 6 weeks , at least initially , they say . They also note there are other drug affected by weight unit that should be reevaluated while taking incretins , such as hormonal parentage control .
