What are the possible side effects of injectable Tirzepatide?
Safety and Side Effects of Tirzepatide
Some FDA-approved versions of tirzepatide have been studied in clinical trials for type 2 diabetes and chronic weight management. These studies describe the types of side effects participants reported when using the medication under medical supervision. These findings apply only to FDA-approved products and do not predict results for compounded tirzepatide.
Compounded tirzepatide is not FDA-approved, but it may be prescribed by licensed healthcare providers when medically appropriate. Because compounded medications have not been evaluated by the FDA for safety or effectiveness, your provider will monitor your response closely.
Commonly Reported Side Effects
People taking tirzepatide may experience digestive-related symptoms. Commonly reported side effects include:
- Nausea
- Vomiting
- Stomach discomfort
- Diarrhea or constipation
Responses vary from person to person. Some individuals report that these symptoms change over time, while others may continue to experience them.
Less Common but Serious Side Effects
More serious side effects are less commonly reported but can occur. Examples may include:
- Severe abdominal pain (possible pancreatitis)
- Gallbladder issues
- Allergic reactions
- Changes in kidney function
Seek urgent or emergency care if you experience severe, sudden, or concerning symptoms.
Why Monitoring Matters
Because individual responses differ, regular follow-up with your healthcare provider is important. Your provider can:
- Review how you are responding to treatment
- Evaluate any symptoms or changes
- Decide whether the medication remains appropriate for you
Do not adjust your dose or stop treatment without guidance from your provider.

Compounded versions of tirzepatide are not FDA-approved. The FDA has not evaluated compounded tirzepatide for safety, effectiveness, or quality. Compounded medications may differ in formulation, strength, or supporting evidence from FDA-approved products.
