Can you take Mounjaro for prediabetes: What do the NICE UK guidelines say

Prediabetes means your blood sugar is higher than normal, but not high enough to be classified as type 2 diabetes.

Prediabetes is usually tested with an HbA1c blood test, which reflects your average blood sugar over the previous two to three months.

NICE UK uses these thresholds to measure if a person is non-diabetic, pre-diabetic, or diabetic.

Most people with prediabetes have no symptoms at all, which is why it so often turns up by surprise in a routine test.

That said, prediabetes is worth taking seriously.

Without any change to weight, diet, or physical activity, a prediabetic individual may go on to develop type 2 diabetes later on.

Mounjaro is not licensed for prediabetes as a condition in its own right. There is no UK licence that says "use tirzepatide to treat prediabetes."

So if prediabetes is the only thing on your health record, that alone might not help you become eligible for Mounjaro.

But prediabetes is listed as a qualifying condition, along with weight loss, for Mounjaro.

According to NICE guidelines, the medicine is licensed for weight management in adults with a BMI between 35-39.9 and at least one weight-related health condition or with a BMI between 32.5-37.4 with adults from South Asian, Chinese, other Asian, Middle Eastern, Black African, or African-Caribbean ethnic backgrounds.

According to Eli Lilly’s marketing authorisation indications, the medicine is licensed for weight management in adults with a BMI of 30 or above, or 27 or above with at least one weight-related health condition.

The licence lists examples of those conditions, and prediabetes is one of them, alongside high blood pressure, raised cholesterol, sleep apnoea, cardiovascular disease, and type 2 diabetes.

What that means in practice:

If you have prediabetes and a BMI of 27 or above, you might be eligible for Mounjaro.

A prescriber is not prescribing "for prediabetes" as such.

They are prescribing for weight management in someone whose prediabetes is part of the clinical picture.

Here is what the NICE guidelines outline about Mounjaro and prediabetes.

NICE recommends tirzepatide for weight management.

NICE recommends tirzepatide for weight management for people with:

• A BMI between 35 and 39 and above with at least one weight-related health condition, or
• A BMI between 32.5 and 37.4 with at least one weight-related health condition for people from South Asian, Chinese, other Asian, Middle Eastern, Black African, or African-Caribbean ethnic backgrounds.

However, according to the marketing authorisation indications for Mounjaro (tirzepatide) from its manufacturer, Eli Lilly, tirzepatide is recommended for weight management for people with:

• A BMI of 30 and above or 27 and above, along with a weight-related health condition, such as:
  • Hypertension
  • Dyslipidaemia
  • Obstructive sleep apnoea
  • Cardiovascular disease
  • Prediabetes
  • Type 2 diabetes mellitus

NICE has not issued a recommendation to use tirzepatide for prediabetes.

There is no NICE guidance that treats prediabetes as a standalone reason to prescribe Mounjaro.

NICE recommends it for weight management, and people with prediabetes, along with a qualifying BMI, can become eligible for treatment.

For prediabetes without obesity, NICE's approach is lifestyle-first.

NICE guidance on prediabetes centres on changes to diet, physical activity, and weight, together with regular HbA1c monitoring.

Medication is considered in specific circumstances rather than as the automatic first step.

The one GLP-1 medicine NICE has recommended in a prediabetes-adjacent setting is liraglutide, and only under strict criteria (a much higher BMI and additional cardiovascular risk factors).

So, the overall NICE guidance comes down to this: NICE backs tirzepatide for weight management, including people with prediabetes, but it does not tell prescribers to use it for prediabetes alone.

The decision always rests with the prescriber, who considers your medical history before taking a call.

Post the SURMOUNT-1 trial, another study analysed tirzepatide’s (the active ingredient in Mounjaro) safety and its effectiveness for weight loss, as well as for preventing progression of type 2 diabetes over 3 years (i.e., 176 weeks).

What the 3-year results show

• Out of 1032 participants, only 1.3% participants taking tirzepatide went on to develop type 2 diabetes, as against 13.3% participants taking a placebo.
• 17 weeks after stopping the treatment, only 2.4% participants taking tirzepatide developed type 2 diabetes, as against 13.7% participants taking a placebo.
• Over 176 weeks, participants lost between 12% and 20% of their weight while on tirzepatide.

Prediabetes is largely driven by insulin resistance, where the body stops responding to insulin as well as it should, often linked to carrying extra weight, especially around the belly.

Lose a meaningful amount of that weight, and the body's response to insulin tends to improve, which brings blood sugar back down.

Mounjaro works by mimicking two gut hormones (GLP-1 and GIP) that reduce appetite and slow digestion, so you eat less without a constant fight against hunger.

The weight loss that follows is what improves your blood sugar.

That is also why your glucose levels may begin to spike again if the weight comes back.

Making lifestyle changes is an essential step to prevent prediabetes from progressing to type 2 diabetes.

Here are some practical, day-to-day changes you can incorporate into your daily routine to manage prediabetes before it turns into a concern:

• Eat foods that steady your blood sugar: more fibre, more vegetables and protein, fewer refined carbohydrates and sugary drinks. Our what to eat on Mounjaro guide includes a practical 3-day UK diet plan that applies here too.
• Move more, in whatever way you can. Regular activity improves insulin sensitivity on its own.
• Aim for gradual, sustainable weight loss rather than a crash.
• Get your HbA1c rechecked on the schedule your prescriber suggests, so you can see whether things are moving in the right direction.

Note:

For overweight or obese individuals with prediabetes, Mounjaro is an additional support system that can make the lifestyle changes easier to implement.

For some people, the appetite reduction is what finally makes sustained weight loss possible after years of trying.

That is a legitimate reason to consider it, and nothing to feel awkward about.

But it is not a substitute for the necessary lifestyle changes.

In fact, Mounjaro works best when taken alongside a well-balanced diet and adequate physical activity.

The side effect profile is the same whether you are taking Mounjaro for weight loss, prediabetes-related weight management, or diabetes.

The common effects are digestive and tend to be worse in the first few weeks as the dose builds.

For most people, they ease as the body settles. We track the full timeline of Mounjaro side effects week by week.

Want to know if you are eligible for Mounjaro? Check out the eligibility criteria below:

According to NICE guidelines, you may be eligible for Mounjaro if you:

• Have a BMI between 35 to 39 and above with at least one weight-related health condition
• Belong to South Asian, Chinese, other Asian, Middle Eastern, Black African, or African-Caribbean ethnic backgrounds and have a BMI between 32.5 and 37.4 and above, with at least one weight-related health condition

According to Eli Lilly’s marketing authorisation indications, you may be eligible for Mounjaro if you:

• Have a BMI of 30 and above, or
• Have a BMI of 27 or above, together with a weight-related condition. Prediabetes counts as one of those conditions.

You may not be eligible for Mounjaro if you:

• Are pregnant or planning to become pregnant or breastfeeding
• Have had a serious allergic reaction to tirzepatide

Inform your prescriber before starting Mounjaro if you:

• Are breastfeeding or planning to breastfeed
• Have a history of pancreatitis or gallbladder disease
• Have severe kidney or liver problems
• Have a history of eating disorders
• Are on oral contraception, since GLP-1 medicines can affect how well the pill is absorbed. See Mounjaro and contraception for more details.

You can start a free consultation with a GMC-registered prescriber, who will review your details, including any recent HbA1c result, and tell you whether Mounjaro is right for you.

The entire process of placing an order at OnlineClinic is pretty straightforward and takes only a few minutes. Here’s how it works:

1. Fill in a short medical questionnaire. It takes about 5 to 10 minutes and covers your medical history, current medicines, height and weight, any recent blood test results, and any conditions or allergies. The questions are thorough on purpose, because the prescriber uses them to check if the treatment is safe and appropriate for you.
2. A GMC-registered prescriber reviews your answers. If they need more information, such as a recent HbA1c reading, they message you through your account.
3. If it's approved, it's dispensed and dispatched. Next-day delivery in temperature-controlled packaging, with everything you need (needles, a sharps bin, and the full patient information leaflet).
4. If it isn't approved, the prescriber explains why. They may suggest an alternative. You are not charged for treatment that is not issued.
