Mounjaro (Tirzepatide)


Mounjaro® is a revolutionary medicine for adults with type 2 diabetes and those seeking weight management solutions. Containing the active substance Tirzepatide, Mounjaro works by reducing blood sugar levels when they are high and aiding in weight loss and maintenance by regulating appetite. It is suitable for use alone when metformin cannot be taken or in combination with other diabetes medications when additional blood sugar level control is necessary. Additionally, Mounjaro supports weight loss and maintenance in conjunction with a reduced-calorie diet and increased physical activity for adults with obesity or overweight with weight-related health issues. Available in pre-filled pens for convenient injection, it offers a new hope for effective diabetes management and weight control.

Each pen comes with 4 doses to be taken once a week.


The direction for using Mounjaro involves several steps to ensure safe and effective treatment. Here's a general guide, but always follow your healthcare provider's specific instructions:

1. Starting Dose: Begin with the dose prescribed by your healthcare provider, commonly starting at a lower dose to minimize side effects.

2. Frequency: Mounjaro is injected once a week, on the same day each week, to maintain consistent levels in your body.

3. Injection Sites: The injection can be made into the abdomen, thigh, or upper arm. Rotate the injection site each week to reduce the risk of irritation or other skin reactions.

4. Preparation and Administration:
- Ensure your hands and the injection site are clean.
- If stored in the refrigerator, allow the medication to come to room temperature for a few minutes for more comfortable injection.
- Follow the instructions provided with the medication for attaching the needle, if necessary, and for performing the injection.
- Dispose of needles and syringes safely in a sharps container.

5. Storage: Keep Mounjaro in the refrigerator between 2-8°C (36-46°F). If necessary, it can be kept at room temperature (below 30°C/86°F) for a limited period, as specified by the manufacturer. Do not freeze.

6. Missed Dose: If you miss a dose, inject it as soon as you remember if it's within a few days of the missed dose. If it's almost time for your next dose, skip the missed dose and return to your regular schedule. Do not take two doses at one time to make up for a missed dose.

7. Monitoring and Adjustments: Regular follow-up appointments with your healthcare provider are essential to monitor your response to Mounjaro and adjust the dose if necessary.

8. Side Effects and Precautions: Be aware of potential side effects, and contact your healthcare provider if you experience severe or persistent symptoms.


Mounjaro (tirzepatide) is made of the main active part, tirzepatide, which helps control blood sugar and manage weight. It also has other ingredients like water, preservatives, and stabilizers to keep it safe and effective. For more details, check the medication's package or leaflet.

Side effects

As with any medication, Mounjaro may be associated with certain side effects. Common side effects may include nausea, vomiting, diarrhea, reduced appetite, abdominal pain, and constipation. These effects are typically transient and tend to improve over time. However, it's important to note that individual responses may vary. If you experience severe or persistent side effects, consult a healthcare professional promptly.


When using Mounjaro (tirzepatide), it's important to be aware of the following warnings:

1. Pancreatitis: There is a risk of developing pancreatitis. Watch for symptoms like severe abdominal pain that might also radiate to the back.

2. Hypoglycemia: Especially in combination with other diabetes medications, there's an increased risk of low blood sugar. Monitor your blood sugar levels closely.

3. Kidney Problems: Mounjaro can affect kidney function, so any changes in urination or symptoms of kidney issues should be reported to a healthcare provider.

4. Gastrointestinal Disorders: This medication can cause severe gastrointestinal problems. If you experience persistent vomiting, diarrhea, or other severe symptoms, contact your healthcare provider.

5. Thyroid Cancer: In rodent studies, medications like Mounjaro have been linked to thyroid cancer, so inform your doctor if you have a personal or family history of thyroid cancer or endocrine disorders.

6. Allergic Reactions: Be alert for signs of allergic reactions, including rash, itching, swelling, and difficulty breathing.

7. Pregnancy and Breastfeeding: Mounjaro should be used cautiously during pregnancy and breastfeeding. Discuss potential risks and benefits with your healthcare provider.

8. Pediatric Use: The safety and effectiveness of Mounjaro in individuals under 18 years of age have not been established.

Always consult with your healthcare provider for a complete understanding of the potential risks and guidance tailored to your health situation.

What's the difference between Mounjaro and Wegovy?

Mounjaro (tirzepatide) and Wegovy (semaglutide) are both injectable medications used for managing blood sugar levels in type 2 diabetes and for weight loss in certain patients. The primary difference lies in their mechanisms of action: Mounjaro acts on both GLP-1 and GIP receptors, making it a dual agonist, which helps regulate blood sugar and promotes weight loss. Wegovy acts mainly on the GLP-1 receptors to achieve similar outcomes. This dual action potentially gives Mounjaro a broader impact on blood sugar control and weight management.

Which one is more effective for weight loss, Mounjaro or Wegovy?

Both Mounjaro and Wegovy have been shown to be effective for weight loss. However, studies suggest that Mounjaro, due to its dual action on both GLP-1 and GIP receptors, may offer superior weight loss benefits for some patients compared to medications that act only on GLP-1 receptors, like Wegovy. The effectiveness can vary based on individual patient responses, health conditions, and adherence to the treatment plan.

How do you take Mounjaro?

Mounjaro is administered as a subcutaneous injection once a week. It can be injected into the abdomen, thigh, or upper arm, with the site of injection rotated each week to minimize the risk of skin irritation.

What are the common side effects of Mounjaro?

Common side effects include nausea, vomiting, diarrhea, reduced appetite, abdominal pain, and constipation. Most side effects are mild to moderate and often decrease over time as the body adjusts to the medication.

Can I drink alcohol while taking Mounjaro?

It's advisable to be cautious with alcohol consumption while taking Mounjaro (tirzepatide). Alcohol can affect blood sugar levels and increase the risk of side effects like hypoglycemia, especially in people with diabetes. Additionally, alcohol may amplify some side effects of Mounjaro, such as nausea or dizziness. Before consuming alcohol, discuss it with your healthcare provider to understand how it might interact with your treatment plan and whether any specific recommendations apply to your situation.
