01Mounjaro 101
What is Mounjaro?
Mounjaro is a prescription medicine whose active substance is tirzepatide. It is injected under the skin once a week from a prefilled pen, on the same day each week, according to the European Medicines Agency. Tirzepatide acts in the same way as two hormones made in the gut, GLP-1 and GIP, which the agency says reduces appetite and helps people manage their weight.
Active substance
Tirzepatide. Mounjaro is the brand name; tirzepatide is the medicine inside it.
How it is taken
One injection a week under the skin of the belly, the thigh or the upper arm, according to the European Medicines Agency.
Starting low
The dose starts low and rises in steps, usually 4 weeks apart. Stomach side effects are most likely while it rises.
What it is authorised for
In the European Union, Mounjaro is authorised for type 2 diabetes and, together with diet and physical activity, to help adults lose weight and keep it under control, according to the European Medicines Agency.
Who the weight authorisation covers
Adults with a body mass index (BMI) of 30 or more, or a BMI between 27 and 30 with weight-related health problems such as diabetes, high blood pressure or obstructive sleep apnoea, according to the European Medicines Agency.
How it is obtained
By prescription. At Oshun it is prescribed only after an in-person consultation, and only if Dr. Rockhead judges it suitable.
Keep in mind
Mounjaro works alongside diet and activity.
In the European Union, Mounjaro is authorised for weight management together with diet and physical activity, not in place of them, according to the European Medicines Agency.
Mounjaro is a medicine for a medical condition. Its maker, Eli Lilly, says in an open letter that it is not approved for, and should not be used for, cosmetic weight loss.
Weight often returns when the medicine is stopped. In a study described in Mounjaro's product information, people who stopped it regained a substantial part of the weight they had lost, even though they kept receiving diet and activity advice. Whether and when to stop is a decision you make with Dr. Rockhead.
Our medical weight loss page explains the whole programme: nutrition, activity and monthly follow-up.

Mounjaro and Ozempic are both once-weekly injections, but they contain different active substances. Mounjaro contains tirzepatide, which acts like two gut hormones, GLP-1 and GIP. Ozempic contains semaglutide, which acts like GLP-1 alone, according to the European Medicines Agency.

05Safety & who it is for
What are the side effects of Mounjaro?
The most common side effects of Mounjaro, which may affect more than 1 in 10 people, are nausea, vomiting, abdominal pain, constipation and diarrhoea, and low blood glucose when it is used with insulin or a sulphonylurea, according to the European Medicines Agency.
Who should not take a GLP-1 medicine
An allergy to the medicine; you or anyone in your family has had medullary thyroid cancer or MEN 2 (a condition that causes tumours in more than one gland); severe stomach or bowel disease; a history of pancreatitis; pregnancy or breastfeeding.
The thyroid warning
US labels carry a boxed warning because these medicines caused thyroid tumours in rats. Whether they do in people is unknown.
Pregnancy and breastfeeding
Do not take Mounjaro if you are pregnant, breastfeeding or trying for a baby. Use contraception while you take it, and stop it at least 1 month before trying, according to its product information.
If you take the contraceptive pill
Mounjaro may make the contraceptive pill less reliable. The maker's US prescribing information and the UK medicines regulator both advise switching to a non-oral method, or adding a barrier method such as condoms, for 4 weeks after starting Mounjaro and for 4 weeks after each dose increase. The EU product information does not ask for this. Ask Dr. Rockhead what applies to you, and tell him which contraception you use.
Never combine; never from salons
Do not take it with another GLP-1 or weight-loss medicine. The UK regulator says never to buy GLP-1 medicines from salons or social media.
Before surgery or sedation
Tell your surgeon and your anaesthetist that you take this medicine. Its product information warns that food can stay in the stomach longer, which matters under general anaesthesia or deep sedation.
Go to a hospital at once
For severe stomach pain that does not go away, sometimes spreading to your back, which can be pancreatitis; swelling of the face, lips, tongue or throat, or trouble breathing; or a sudden change in your sight.
Call us
On (876) 676-6297 for pain in the upper stomach with yellow skin or eyes, fever or pale stools; passing much less urine, or swollen legs; a lump in your neck, hoarseness or trouble swallowing; unusual nausea, vomiting or stomach pain; or any new symptom.
