When it comes to the safety of medications for type 2 diabetes and obesity, weighing the potential side effects of the treatment against the risk of not treating the condition is crucial. Thankfully, clinical trials have shown that Mounjaro offers a very favorable risk/benefit profile. However, it’s important to be aware of possible gastrointestinal side effects that may occur in some individuals, including:

  • Nausea
  • Vomiting
  • Diarrhea
  • Constipation
  • Indigestion
  • Reduced appetite
  • Stomach pain

It’s worth noting that these side effects are generally mild to moderate in severity and tend to occur primarily during the dose-escalation period.

While serious side effects are rare, they can include:

  • Pancreatitis (inflammation of the pancreas), which manifests as severe and persistent abdominal pain with or without vomiting.
  • Hypoglycemia (low blood sugar), leading to symptoms such as sweating, headache, confusion, drowsiness, dizziness/light-headedness, weakness, blurred vision, slurred speech, feeling shaky or jittery, increased heart rate, mood changes, or hunger.
  • Serious allergic reactions, characterized by swelling of the lips, tongue, face, or throat, difficulty breathing or swallowing, severe rash or itching, dizziness or fainting, and a very rapid heart rate.
  • Kidney failure in individuals with kidney problems resulting from dehydration caused by diarrhea, nausea, and vomiting.
  • Severe or persistent stomach problems.
  • Changes in vision, such as blurred vision, floaters, or loss of vision.


Mounjaro may potentially cause thyroid tumors of thyroid cancer. Be attentive to symptoms like a lump or swelling in the neck, difficulty swallowing, shortness of breath, or hoarseness.

Please note that the following individuals should not take Mounjaro:

  • Individuals with a history or family history of medullary thyroid carcinoma (MTC)
  • Individuals with multiple endocrine neoplasia syndrome type 2 (MEN2)
  • Individuals with an allergy to any of the ingredients of Mounjaro
  • Individuals who are pregnant or breastfeeding

If you have any concerns or experience any of these side effects, please consult with a healthcare professional immediately.
