1. What is Mounjaro and what is it used for
Mounjaro contains the active substance tirzepatide and is used to treat adults with type 2 diabetes mellitus. Mounjaro lowers blood sugar levels only when blood sugar levels are high.
Mounjaro is also used to treat adults with obesity or overweight (with a BMI of at least 27 kg/m2). Mounjaro affects appetite regulation, which can help you eat less food and reduce your body weight.
In type 2 diabetes, Mounjaro is used:
- on its own when you cannot take metformin (another diabetes medicine).
- or in combination with other diabetes medicines when these are not enough to control the sugar levels in your blood. These other medicines may be taken by mouth and/or may be an insulin injection.
Mounjaro is also used together with diet and exercise to lose weight and help keep weight under control in adults who have:
- a BMI of 30 kg/m² or more (obesity) or
- a BMI of at least 27 kg/m², but less than 30 kg/m² (overweight) and weight-related health problems (such as prediabetes, type 2 diabetes, high blood pressure, abnormal fat levels in the blood, breathing problems during sleep called "obstructive sleep apnea" or a history of heart attack, stroke, or vascular problems)
Body Mass Index (BMI) is a measure of your weight in relation to your height.
In patients with obstructive sleep apnea (OSA) and obesity, Mounjaro can be used with or without positive airway pressure therapy.
It is important that you follow the advice about your diet and physical activity that your doctor, nurse, or pharmacist gives you.
2. What you need to know before you use Mounjaro
Do not use Mounjaro
- if you are allergic to tirzepatide or any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Talk to your doctor, pharmacist, or nurse before you start using Mounjaro if:
- you have severe problems with digestion of food or food stays in your stomach for longer than usual (including severe gastroparesis).
- you have ever had pancreatitis (inflammation of the pancreas, which can cause severe pain in the stomach and back that does not go away).
- you have any problems with your eyes (diabetic retinopathy or macular edema).
- you are taking a sulfonylurea (another diabetes medicine) or insulin for diabetes, as you may get low blood sugar (hypoglycemia). Your doctor may need to adjust the dose of these medicines to reduce this risk.
When you start treatment with Mounjaro, you may experience fluid loss/dehydration, such as when you vomit, feel sick, and/or have diarrhea, which can cause a decrease in kidney function. To avoid dehydration, it is important to drink plenty of fluids. Contact your doctor if you have any questions or concerns.
If you are going to have surgery and will be under anesthesia (put to sleep), tell your doctor that you are taking Mounjaro.
Children and adolescents
This medicine must not be given to children and adolescents under 18 years of age because it has not been studied in this age group.
Other medicines and Mounjaro
Tell your doctor, pharmacist, or nurse if you are using, have recently used, or might use any other medicines.
Pregnancy
If you are pregnant, think you may be pregnant, or plan to become pregnant, consult your doctor before using this medicine. This medicine must not be used during pregnancy because the effects of this medicine on the fetus are not known. Therefore, it is recommended to use contraceptive methods while using this medicine.
Breast-feeding
It is not known whether tirzepatide passes into breast milk. A risk to newborns/infants cannot be ruled out. If you are breast-feeding or plan to breast-feed, consult your doctor before using this medicine. You and your doctor must decide whether to stop breast-feeding or stop using Mounjaro.
Driving and using machines
This medicine is unlikely to affect your ability to drive or use machines. However, if you use Mounjaro with a sulfonylurea or insulin, you may get low blood sugar (hypoglycemia) that can reduce your ability to concentrate. Avoid driving or using machines if you have any signs of low blood sugar, such as headache, drowsiness, weakness, dizziness, hunger, confusion, irritability, rapid heartbeat, and sweating (see section 4). See section 2, "Warnings and precautions" for information on the increased risk of getting low blood sugar. Consult your doctor for more information.
Mounjaro contains sodium
This medicine contains less than 1 mmol of sodium (23 mg) per dose, which is essentially "sodium-free".
3. How to use Mounjaro
Follow the instructions for administration of this medicine exactly as your doctor or pharmacist has told you. If you are not sure, ask your doctor or pharmacist again.
How much to use
- The starting dose is 2.5 mg once a week for four weeks. After four weeks, your doctor will increase your dose to 5 mg once a week.
- Your doctor may increase your dose in increments of 2.5 mg up to 7.5 mg, 10 mg, 12.5 mg, or 15 mg once a week if needed. In each case, your doctor will tell you to stay on a specific dose for at least 4 weeks before moving to a higher dose.
Do not change your dose unless your doctor has told you to.
Each pen contains a dose of Mounjaro of 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, or 15 mg.
When to use Mounjaro
You can use your pen at any time of day, with or without food. If you can, you should use it on the same day each week. To help you remember when to use Mounjaro, you can write the day of the week when you inject your first dose on the pen box or on a calendar.
If necessary, you can change the day of your weekly Mounjaro injection, as long as at least 3 days have passed since your last injection. After selecting a new dosing day, continue with once-weekly administration on that new day.
How to inject Mounjaro
Mounjaro is injected under the skin (subcutaneous injection) in the abdominal area at least 5 cm away from the navel or in the upper thigh or upper arm. You may need help from another person if you want to inject into the upper arm.
If you want, you can inject into the same area of your body each week. But in this case, make sure to choose different injection sites within the same area. If you also inject insulin, choose a different injection site for that injection.
Before using Mounjaro, read the "Instructions for use" of the pen carefully.
Monitoring of blood sugar levels
If you are using Mounjaro with a sulfonylurea or insulin, it is important that you monitor your blood sugar levels as instructed by your doctor, nurse, or pharmacist (see section 2, "Warnings and precautions").
If you use more Mounjaro than you should
If you use more Mounjaro than you should, talk to your doctor immediately. Too much medicine can cause your blood sugar levels to drop too low (hypoglycemia) and can also cause nausea or vomiting.
If you forget to use Mounjaro
If you miss an injection and,
- it has been 4days or lesssince you should have used Mounjaro, use it as soon as you remember. Then inject your next dose as usual on your scheduled day.
- it has been more than 4dayssince you should have used Mounjaro, skip the missed dose. Then inject your next dose as usual on your scheduled day.
Do not inject a double dose to make up for a missed dose. The minimum time between two doses must be at least 3 days.
If you stop using Mounjaro
Do not stop using Mounjaro without talking to your doctor. If you stop using Mounjaro and have type 2 diabetes, your blood sugar levels may increase.
If you have any other questions about the use of this medicine, ask your doctor, pharmacist, or nurse.
