What’s Changing?

Eli Lilly—the maker of Mounjaro (tirzepatide)—has announced a steep price increase starting in September 2025:

  • 5 mg dose: from around £92 to about £180.

Reddit Roots: Real Voices, Real Worry

Across Reddit forums like r/Mounjaro and r/MounjaroUK, users are candidly sharing how the price hike is causing anxiety and disappointment:

“It’s an absolute disgrace… most people just won’t be able to afford it.”
(Reddit, Reddit)

“I only started a week ago… if the prices are going up 170% this could be the end of my journey so soon.”
(Reddit)

“I’ve lost 1½ stone… they dropped that on us with just two weeks’ notice... for people mid-treatment, this isn’t just annoying, it’s a disruptive blow.”
(Reddit)

Many users are trying to stretch existing pens, taper doses, or scramble to secure supplies before September:

“I'm going to somehow afford to at least titrate down month on month… I have formed better habits but I’m not sure they will be enough alone.”
(Reddit)

And others are preparing to switch drugs:

“I intend to switch to WeGovy once my Mounjaro stocks run out.”
(Reddit)

There’s also frustration about the role of big pharma:

“Big pharma doesn’t absorb the hit … they just dump it somewhere else. In this case… us.”
(Reddit)

Why It Matters

Why does this matter so much? Because Mounjaro isn't just a treatment—it's often a lifeline.

  • Many users have seen dramatic health improvements: weight loss, better energy, improved blood sugar control.
  • Stopping abruptly can lead to rebound weight gain or loss of stability. As one expert warns, “patients may regain weight quickly after stopping treatment.”
    (The Times)
  • Health inequalities deepen when life-improving medications become unaffordable.
  • Panic-buying is already evident: Asda’s telehealth arm reported a 350% surge in demand, while MedExpress saw a 40% increase as users tried to stockpile ahead of September.

The Risks of Shortcuts

The financial pressure is prompting risky behaviour: some users are heavily stockpiling—drawing concern from professionals:

“A 30-year-old… has gone into £700 of debt to secure a £2,000 supply… raising concerns about shortages for diabetic patients.”
(The Sun)

Authorities strongly advise against turning to unregulated alternatives—not only for ethical reasons, but for safety. Buying outside medical supervision can expose patients to counterfeit medicines or unsafe dosing.

Expert Advice and Alternatives

Obesity specialists are urging caution but also encouraging patients to seek safe solutions:

  • Professor Naveed Sattar highlights that the health benefits (e.g. reduced risk of heart disease and diabetes) still outweigh many side effects—if the treatment is affordable.
    (The Times – expert advice)

Options include:

  • Tapering doses under medical supervision.
  • Exploring alternatives such as Wegovy, which may be more affordable (though results can vary).
  • Checking NHS eligibility with a GP or pharmacist.

Most importantly, patients should not change treatment plans without consulting a healthcare professional.

Moving Forward Together

While the price hike is beyond patient control, how people respond is crucial:

  1. Stay informed about the changes.
  2. Consult healthcare providers before stopping, switching, or stockpiling.
  3. Lean on community—Reddit, blogs, and support groups provide a network for advice and solidarity.

Mounjaro has enabled life-changing progress for many. This price rise underscores a bigger challenge: ensuring that transformative medicines remain accessible, safe, and equitable for all.
