How long do Mounjaro side effects last?

People commonly report side effects such as nausea, vomiting, headache, stomach discomfort, and low blood sugar when starting Mounjaro weight loss medication. These effects usually appear during the early phase of treatment, while the body is adjusting to the weight loss injection.

As treatment continues, side effects tend to ease as your body becomes more familiar with the medication. For many individuals, this adjustment period lasts around four weeks, although the exact timeframe can vary from person to person.
