The duration of side effects caused by Mounjaro (tirzepatide) varies for each individual. Generally, these side effects are categorised as mild to moderate in terms of severity and commonly occur when initiating the medication or when the dosage is increased. Due to the prolonged effect of the medication, it is possible for side effects to persist for several days to weeks, depending on the person. Typical side effects include stomach discomfort, nausea, vomiting, heartburn, diarrhoea, and constipation. You must consult your doctor if you experience side effects while taking Mounjaro that cause concern or fail to improve over time. Sometimes, patients may be advised to maintain a particular dosage for an extended period or reduce it to a lower dose to allow the body more time to adapt.
