GLP-1 and Gout: What UK Patients Should Know (October 2026)

01 · The core answer

Does GLP-1 treatment cause gout?

Gout is not listed as a side effect of Mounjaro in the UK patient leaflet.¹¹³ We also cannot rule out that someone starting treatment will have a flare around the same time. Gout can arise for many reasons, and starting a weight-loss medicine is one of several changes happening in a person's life at that point.

If you want a more detailed look at the question, our related guides on whether GLP-1 medicines can cause gout and whether Mounjaro can cause gout go further.

02 · What to do

The decisions you are actually facing

Most readers are in one of three positions.

In every case the principle is the same: share the information and let a clinician weigh it. Our Mounjaro and gout guide covers the same ground with a treatment focus.

04 · What the label says

What the UK product information says about gout

The UK Summary of Product Characteristics and patient information leaflet for Mounjaro do not list gout as a side effect.¹¹³

That does not mean nobody with gout has ever taken the medicine, or that nobody has had a flare while on it. It means the manufacturer and regulators have not identified gout as an established effect of tirzepatide. Those are different statements, and conflating them in either direction would mislead you.

We would also caution against the opposite error. Absence from a leaflet is not a promise that nothing will ever happen to your joints. Medicines are monitored after launch, and labels are updated when new evidence emerges. This is exactly why the reporting system exists.

If you notice a new symptom after starting treatment, including joint pain, swelling or heat in a joint, tell your prescriber. You can also report a suspected side effect yourself through the MHRA Yellow Card scheme.¹⁹ Reports from patients and clinicians are how safety signals are detected, and a report does not mean you are certain the medicine is responsible.

Our related guide on Mounjaro and gout flare-ups applies the same approach to the flare-specific question, and the answer is consistent: the label does not list it, so talk to a clinician about anything new.

05 · Why the question arises

Why people link GLP-1 medicines and gout

The link is easy to understand even though the label does not support it. Treatment aims at substantial weight reduction, and anything that changes the body noticeably gets blamed when something else changes at the same time. If a flare follows a new injection, the connection feels obvious.

Tirzepatide activates two natural gut-hormone receptors at once: GIP and GLP-1. Together these help regulate appetite, slow how quickly the stomach empties, and improve the way the body responds to insulin.¹ In practice, most people feel fuller sooner and less hungry between meals, which supports a reduced-calorie diet.

Whether your treatment affects your gout is a question for your GP, who knows your history and can look at your blood tests.

If you have noticed a pattern in your own body, such as flares following particular weeks of treatment, write down the dates, your doses and what you ate and drank.

06 · If you already have gout

If you already have gout before starting

Tell the prescriber about your gout during the consultation. Our consultation is free, and it is reviewed by a GPhC-registered prescriber, not a scoring script. They look at your full health picture, and gout is part of that picture.

Be specific. Say when you were diagnosed, how often you get flares, and which medicines you take for gout or to prevent it. Include anything you buy over the counter. A prescriber can only weigh something they know about, and a complete medicines list is the single most useful thing you can provide.

Do not stop or change any gout medicine because you are starting weight-loss treatment, unless the clinician who prescribed it tells you to.

Also be honest about related conditions. Joint disease often sits alongside other health problems, and a prescriber needs the whole list. If you are unsure of your own history, ask your GP surgery for a summary before you complete the questionnaire.

Payment is taken when you place the order; if the prescriber decides the treatment is not suitable, the order is refunded automatically in full. That means being open about your gout carries no financial penalty.

If treatment goes ahead, ongoing monthly reviews, follow-up assessments and side-effect support are part of the aftercare, so you have a route to raise any joint symptoms as they arise. Repeat orders also re-check suitability, so changes in your health are picked up each time rather than assumed away.

Finally, keep your GP in the loop. We would rather you had two clinicians who know about each other's decisions than one who was never told. Your GP will also hold blood results that we may not see.

07 · During a flare

What to do if you get a flare on treatment

Contact a clinician rather than guessing. A hot, swollen, painful joint needs proper assessment, because several conditions can look similar. Your GP, an NHS urgent advice service or a pharmacist can help you decide how quickly you need to be seen. If symptoms are severe, sudden or accompanied by feeling generally unwell, seek urgent medical help.

The reliable answer is that a clinician who knows your history should guide treatment of a flare.

Do not stop prescribed medicines on your own. Do not add new medicines or supplements without checking they suit you. Do not ignore a joint that is getting worse. And tell your treatment prescriber that you have had a flare, so it is on record.

Telling us matters for another reason. If you are on treatment and think a symptom may relate to the medicine, report it through the MHRA Yellow Card scheme.¹⁹ Reporting is open to patients as well as healthcare professionals, and it feeds the national picture of how medicines behave in real life.

Whether to pause treatment during a flare is a clinical decision. Contact the prescribing team, who can review your situation, your dose and your recent changes with you. Support is available Monday to Friday, by email at support@everydaymeds.co.uk, through the account portal chat, or by phone on 0333 207 0413.

Afterwards, ask your GP whether any follow-up tests make sense for you. Understanding your own pattern is the best protection against repeated flares.

08 · Pace of weight loss

What the trials show about weight loss

In the SURMOUNT-1 trial of 2,539 adults, people taking tirzepatide alongside diet and exercise lost on average 15% of their body weight on 5mg, 19.5% on 10mg and 20.9% on 15mg over 72 weeks, compared with 3.1% with lifestyle changes alone.² These are trial averages, and individual results vary. Treatment works alongside a reduced-calorie diet and increased physical activity, not instead of them.

Those results were reached over a long period, not overnight. Trial averages do not predict your own result, and the pace at which any one person loses weight depends on many factors.

The same trial reported that at 72 weeks, 85% of participants on 5mg, 89% on 10mg and 91% on 15mg had lost at least 5% of their body weight.² Half of participants on 10mg and 57% on 15mg lost at least 20% of their body weight.

For a worked example only: for someone starting at 100 kg, 20.9% is about 21 kg over the trial period. That is an average at the highest dose, not a target or expectation.

If you are prone to gout, talk to your GP about your own results and monitoring.

09 · Who should avoid treatment

Who should avoid GLP-1 medicines?

Mounjaro is a prescription-only medicine, supplied only after an online consultation reviewed by a GPhC-registered prescriber.¹ It is used alongside a reduced-calorie diet and increased physical activity.

The full list of cautions and reasons not to use the medicine is in the patient information leaflet, which you should read before starting.¹³ Your prescriber will also go through the points that apply to you. You should not take Mounjaro if you are allergic to tirzepatide or any of its ingredients, and it should not be used during pregnancy or while trying to conceive; stop it at least one month before trying to conceive. Your prescriber will take extra care, or may recommend against treatment, if you have a history of pancreatitis, severe gut or digestive disease, diabetic retinopathy, or gallbladder problems. Always share your full medical history and medicine list during consultation.

Answer every question accurately. Include every diagnosis, including joint conditions such as gout, and every medicine, prescribed or bought over the counter. Mention anything that has changed recently. A questionnaire is only as good as the answers given to it.

The consultation is free, with no obligation, and the price shown is the price paid, with no hidden fees. If the prescriber decides that treatment is not suitable, the order is refunded automatically in full.

The licence also sets who treatment is intended for. Mounjaro is licensed in the UK for weight management in adults and for type 2 diabetes.

If you are unsure whether you should even apply, speak to your GP or pharmacist first. That is not a brush-off. It is the sensible step if you have a complicated medical history, and a good prescriber will tell you the same.

10 · Serious side effects

Serious side effects: when to get help straight away

Serious side effects are uncommon but need urgent attention. 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 skin/eyes (possible gallbladder problems); or signs of a severe allergic reaction such as swelling of the face or throat and difficulty breathing. If you take insulin or a sulfonylurea alongside Mounjaro, watch for low blood sugar (shakiness, sweating, confusion) — your prescriber may need to adjust those medicines.¹

11 · NHS, private and ordering

NHS or private: getting treatment if you have gout

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, and the NHS primary-care rollout began in June 2025 with the highest-need groups first, initially BMI 40 and above with four or more qualifying conditions.⁴⁶ Full rollout is expected to take years, which is why many people who meet the licensed criteria choose regulated private treatment rather than waiting.

If you have gout and are weighing the routes, your GP is the right first conversation. They can tell you where you sit in the NHS rollout, and they hold your blood results and joint history. NHS access to Wegovy runs through specialist weight-management services, so ask your GP about that too.

If you choose private treatment, here is how ordering works with us.

• Free online consultation. A short health questionnaire, no charge, no obligation. Mention your gout here.
• Prescriber review. A GPhC-registered prescriber reviews your answers. Payment is taken when you place the order; if the prescriber decides the treatment is not suitable, the order is refunded automatically in full.
• Dispensing and delivery. Our registered pharmacy dispenses, with same-day dispatch when ordered by 3pm and free next-day tracked delivery in discreet, temperature-controlled packaging. Saturday delivery is £14.99.

All six doses are in stock. You can see the full range on the Mounjaro pen page.

Our medicine comes through official LillyDirect supply, sourced directly from Eli Lilly, as genuine KwikPens. Needles, a sharps bin and injection guidance are included with every order. Ongoing monthly reviews are part of the service, so you have somewhere to raise joint symptoms if they appear.

Payment options include Visa, Mastercard and Klarna, with pay-monthly choices and no subscriptions. Repeat orders re-check suitability and nothing ships automatically.
