Mounjaro has not been reported to cause headaches, but you may develop one if your blood sugar levels get too low.
In Mounjaro’s clinical trials, participants did not report headaches as a side effect of taking the medication.
But if you take Mounjaro and experience headaches, this could be related to other side effects of the drug, such as hypoglycemia. Hypoglycemia means your blood sugar levels become too low, and this manifests with symptoms like:
- headaches
- dizziness and lightheadedness
- sweating more than usual
- confusion
- blurry vision
- slurred speech
- feeling weak, shaky, or jittery
- rapid heart rate
- mood changes, such as anxiety and irritability
- hunger
These symptoms may be mild at first, but if hypoglycemia is not treated, they can worsen and become life threatening.
Mounjaro may also increase your chances of dehydration, which can also cause symptoms like headaches, dizziness, and nausea. Nausea was commonly reported among Mounjaro users in clinical trials.
To reduce the chances of experiencing headaches while using Mounjaro, the first step is learning to identify the side effects of the drug. For example, hypoglycemia and dehydration.
You may manage those side effects by:
- drinking plenty of liquids, like water and broth
- eating small meals more frequently
- avoiding skipping meals
- monitoring your blood sugar levels regularly
Medical Perspective“Maintaining adequate hydration prevents headaches because it allows your body to stay balanced and provide blood flow to your brain. Your body and brain require adequate fluids to work properly.”

No, Mounjaro doesn’t help manage or prevent migraine attacks.
Mounjaro is approved by the Food and Drug Administration (FDA) for the treatment of high blood sugar in people with type 2 diabetes. Some doctors may also prescribe it off-label for weight loss. Off-label use is when a drug is prescribed for a condition other than what it is formally approved for.
Mounjaro does not have FDA approval to help treat or prevent migraine.
Although headaches are not a reported side effect of Mounjaro, they could be a consequence of low blood sugar levels or dehydration, which the drug can cause.
If you’re experiencing recurrent headaches while using Mounjaro, even if you are not dehydrated or experiencing hypoglycemia, it’s important to talk with a healthcare professional to explore other possible causes.
If you have symptoms like blurry vision, shortness of breath, dizziness, unexplained fatigue, or rapid heartbeats, it’s important to seek emergency care.
