Does Mounjaro (tirzepatide) make you tired? (cause fatigue)

Some people taking Mounjaro® have reported feeling tired, but fatigue is not listed by the manufacturer as a potential side effect. There can be many reasons why someone might feel more fatigued while on a Mounjaro prescription. For example, the medication can decrease appetite and with reduced caloric intake energy may drop. If combined with other medications for treating type 2 diabetes there is the risk for hypoglycemia (low blood sugars) which can manifest with symptoms of fatigue. If you are experiencing new symptoms of fatigue since starting Mounjaro, speak to your prescribing medical provider right away.
