Mounjaro and Similar Products: What Is Actually Comparable (October 2026)

01 · The short answer

What is comparable to Mounjaro?

Only prescription GLP-1 medicines are genuinely comparable. Mounjaro is the brand name for tirzepatide, a once-weekly injectable made by Eli Lilly.¹ Tirzepatide is the first treatment of its kind to activate two natural gut-hormone receptors at once: GIP and GLP-1.¹ That dual action is what distinguishes it from single-action GLP-1 medicines such as semaglutide (Wegovy/Ozempic). Ozempic is licensed for type 2 diabetes only; it is not a UK weight-loss medicine.¹

02 · Your decision

Which one should you look at?

Start with your reason for looking. If you are weighing up Mounjaro against Wegovy, a prescriber can review which fits you better. Our weight loss clinic starts with a free consultation reviewed by a GPhC-registered prescriber.

If you are already leaning towards tirzepatide, the Mounjaro pen starts at £169.99 for the 2.5mg starter, and your first order is £40 less with code FIRST40. For a wider view, see our guide to medications similar to Mounjaro.

03 · Licensed alternatives

Licensed alternatives to Mounjaro

Wegovy is the closest licensed alternative for weight management. It is semaglutide, a single-action GLP-1 medicine, taken once weekly. The pens run 0.25mg, 0.5mg, 1mg, 1.7mg and 2.4mg, stepping up after 4 weeks on each of 0.25mg, 0.5mg, 1mg and 1.7mg, so the 2.4mg maintenance dose starts from week 17.¹⁸ You can see the Wegovy pen on our site.

Liraglutide, sold as Saxenda and in products such as Erly, is supplied at 6mg per millilitre. It is a daily injection, unlike once-weekly Mounjaro and Wegovy. Our guide to Mounjaro similar drugs goes through the differences in more detail.

Mounjaro itself is licensed in the UK for weight management in adults and for type 2 diabetes.¹

04 · Tablets and safety

Tablet versions and which is safer

There is no tablet version of Mounjaro, which comes as a pre-filled KwikPen.¹ Separate oral GLP-1 medicines exist, including Wegovy tablets and Foundayo, each with its own product information.²⁰²¹ They are different medicines, so do not assume their results match Mounjaro's. Check current Wegovy tablet prices on the product page.

No medicine is safe for everyone, so there is no single safest GLP-1. Mounjaro and Wegovy are both licensed, and each has its own side-effect profile in its product information. A prescriber weighs your health history, other medicines and goals. Report any new symptom through the Yellow Card scheme.¹⁹ Seek immediate medical help for severe, persistent stomach pain that may spread to your back, with or without vomiting (possible pancreatitis); pain in the upper right abdomen, fever or yellowing of the skin or eyes (possible gallbladder problems); or signs of a severe allergic reaction such as swelling of the face or throat and difficulty breathing.

05 · Natural alternatives

Natural and supplement alternatives

No supplement, tea or food reproduces what a GLP-1 medicine does. Products nicknamed "nature's Ozempic" or the "poor man's Ozempic", such as berberine, are low-cost supplements with no clinical oversight. Their dosing is not standardised, and they have not been shown to match the licensed medicines. Dramatic weight-loss claims on these products should be treated with caution.

Food and lifestyle can support appetite control, and that matters because Mounjaro is used alongside a reduced-calorie diet and increased physical activity.¹ That is support, not a substitute. Read more on GLP-1 similar supplements and whether berberine is similar to GLP-1.

06 · NHS access

NHS access

Mounjaro is available on the NHS, but access is being phased in over several years. NICE recommends it for adults with a BMI of at least 35 plus at least one weight-related condition. The NHS primary-care rollout began in June 2025 with the highest-need groups first, initially BMI 40+ with four or more qualifying conditions.⁴⁶ Many people who meet the licensed criteria choose regulated private treatment rather than waiting. Our Mounjaro products page covers the options.
