Mounjaro (Tirzepatide)

Mounjaro is a prescription injectable medicine used to help with losing weight.

Mounjaro works by mimicking the hormones glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). This helps your body regulate your appetite, feel fuller for longer and reduce cravings.

Mounjaro is a self-injectable medicine which you’ll take once per week.

You don’t have to take it with a meal, but you should always aim to take your medicine at the same time each week.

Each Mounjaro pen contains four doses, meaning you can use it up to four times.

You should never use the same needle more than once (each Mounjaro pen comes with four).

While Mounjaro is available in six different doses (2.5mg, 5mg, 7.5mg, 10mg, 12.5mg and 15mg), you should always start with 2.5mg, even if you’ve used a weight loss injection before.

You’ll continue on a dose of 15mg once you’ve reached it for the remainder of your weight loss.

Our UK-based clinicians review each order to make sure its safe. We’ll let you know if we think you should be on a different dose and you won’t be charged until your medicine is on its way to you.

Everyone’s experience with Mounjaro may be different. However, common side effects can include:

• Nausea
• Diarrhea
• Decreased appetite
• Vomiting
• Constipation
• Indigestion
• Stomach Pain

You should talk to your doctor if you have side effects that bother you or do not go away. In the event of an emergency, call 999. 

In trials, Mounjaro was used to achieve an average 12-15% decrease in body weight after 24 weeks and a 16-22% decrease after 72 weeks.  

You shouldn’t take Mounjaro if you’ve had Thyroid cancer or your family has a history of Thyroid cancer or Pancreatitis – or if you have multiple endocrine neoplasia syndrome II.

You also should not take medicine which contains one or more ingredients to which you have an allergy.

You should not take Mounjaro if you’re if you’re pregnant (or planning a pregnancy) or use it with children.

Mounjaro is considered safe for its approved uses. 

As with all medication, you must always follow directions for how to use it. 

If you miss a dose of Wegovy, here’s what you’ll need to do.

If it’s been less than 4 days since your last dose, you should inject as soon as possible and continue with your normal routine.

If it’s been more than 4 days since your last dose, you should not take the missed dose and inject again on your next scheduled day. 

You should not take more than 2 doses within 3 days of each other.

Mounjaro doesn’t stop you from eating any foods (unless you’re allergic or intolerant).

However, you may want to avoid foods with a strong smell or taste, if you experience nausea.

Mounjaro is most effective when coupled with lifestyle changes, so you may also benefit from changing your diet towards eating less fats or fatty foods.
