In-depth Look at Mounjaro and Its Side Effects

Mounjaro (tirzepatide) is a new weight loss injection used by many to overcome obesity. It does this by supressing the appetitie, and is loved by many for its effectiveness.  While this prescription only, one a week injection may look like an attractive proposition, it comes with potential side effects that you should consider before starting this very effective weight loss injection. 

Common side effects of Mounjaro

Mounjaro’s possible side effects range from mild to serious. Common side effects include:

• Feeling and being sick

• Diarrhoea

• Being less hungry than normal

• Constipation

• Stomach pain

• Indigestion and heartburn

• Reactions where the drug was injected

These effects are usually mild. They often go away without much help (Drugs.com, 2024).

Serious side effects and risks

Most side effects of Mounjaro are quite easy to deal with. However, some can be severe. These require medical attention right away:

• Inflammation of the pancreas

• Severe stomach problems

• Very low blood sugar (especially if used with other diabetes medicines)

• Gallbladder disease

• Thyroid tumours (very serious risk)

• Severe allergic reactions

If you have any of these side effects, call your doctor or seek emergency care right away.

Duration of side effects

Most mild side effects of Mounjaro are temporary. They usually appear within the first few weeks of treatment. They may last from a few days to several weeks. Managing them involves treating the symptoms. Sometimes, you might need to talk to your doctor about adjusting your dose.

If side effects last a long time or bother you a lot, you may need to talk to your doctor about whether Mounjaro is still the best choice for you.
