Mounjaro Price Comparison UK – Cheapest Pens & Hidden Costs
Mounjaro (tirzepatide) remains one of the most sought-after weight loss treatments in the UK. But with prices that vary significantly between pharmacies and doses, understanding the true cost requires a careful look at both the headline figures and the often-overlooked extras. This guide uses verified data from independent price trackers and GPhC-registered pharmacies to give you a clear picture of what you can expect to pay in May 2026.

Often included in pen price
Mounjaro is sold as a 4‑week pen with four weekly doses. The monthly cost is therefore the pen price. The lowest visible prices for the 2.5mg starter pen start at around £119.95–£143.99, while higher doses can climb above £300 per pen, depending on the pharmacy and any active promotions.
Key insights
- Starter doses (2.5mg/5mg) see the widest price competition, with ranges between £120–£150.
- Higher doses (10mg–15mg) can be up to 40% more expensive than starter doses.
- Online-only pharmacies (MedEazy, WePrescribe) consistently beat high-street names (Boots, Lloyds) on price.
- Consultation fees are the hidden cost variable: some include it, some charge £30–£50 extra.
- Prices in 2026 have risen approximately 5–10% compared to late 2025 data.
- No single pharmacy is cheapest across all doses — switching pharmacies per dose can save money.

Which UK Pharmacy Sells the Cheapest Mounjaro Pens?
According to data aggregated by Monj: Mounjaro Price Comparison UK, the cheapest pens in May 2026 are largely sold by online‑only providers. MedEazy currently lists the lowest 2.5mg price at £119.95, though WePrescribe, Click Pharmacy, and others also post competitive rates when discounts are applied.
Boots vs Lloyds vs Oxford Online: price showdown
The high‑street names tend to charge a premium. Oxford Online Pharmacy, for example, quoted £149.95 for a 2.5mg pen, while Lloyds Pharmacy came in at £179.99 and Boots at £176.97. These figures, published in Oxford Online’s own comparison blog, illustrate the gap between online and physical pharmacy pricing.
MedEazy vs WePrescribe vs The Care Pharmacy pricing
MedEazy’s £119.95 starter pen undercuts most rivals, but WePrescribe offers a 10% discount code that brings its 2.5mg pen to roughly £129.59. The Care Pharmacy’s guide states monthly costs range “from approximately £120 to £340 depending on dose and pharmacy.” None of these prices include delivery unless stated.
Why monj.co.uk is the most transparent comparison tool
Monj claims to list “no hidden costs” and compares consultations from UK‑licensed, GPhC‑registered pharmacies. While that claim has not been independently audited, the platform does offer a live price table that filters by dose and shows which pharmacies include consultation and delivery. It remains one of the few sources that lets you see the all‑in‑cost at a glance.
Because prices vary by dose, consider ordering different strengths from different pharmacies. For instance, MedEazy may be cheapest for 2.5mg, while WePrescribe could offer a better deal on 10mg. Always factor in delivery and consultation fees before switching.
Are There Hidden Fees Like Consultation or Delivery for Mounjaro?
Headline pen prices rarely tell the full story. Common extra costs include consultation fees, delivery charges, starter‑only discounts, auto‑renewal fees, dose‑change medical reviews, and ancillaries like needles and sharps bins. Several comparison pages explicitly warn that the true monthly cost depends on these add‑ons.
Breakdown of total cost: pen + consultation + delivery
A £130 pen could easily become £150+ after a £30 consultation and £5 delivery. Some pharmacies bundle everything into one price; others charge separately. On the Medino price comparison, average UK monthly costs are listed as £169.16 for 2.5mg and £319.14 for 15mg — figures that already account for typical extras.
Pharmacies with free consultation vs paid
Providers like WePrescribe and Click Pharmacy sometimes include the consultation in the pen price, while others such as The Care Pharmacy charge a separate fee. Monj’s comparison allows you to filter by “consultation included,” but it is worth double‑checking the pharmacy’s own terms before ordering.
Cost comparison including delivery fees
Delivery charges typically range from free (on orders over £150) to £9.99 for temperature‑controlled shipping. Some pharmacies also apply a fee for faster delivery. These amounts are small but can push a marginally cheaper pen above a competitor’s total.
A few online pharmacies set up auto‑renewal subscriptions that continue to charge monthly unless you cancel. Always review the checkout terms and look for “one‑time purchase” options. The Medino comparison specifically warns about auto‑renewal and dose‑change fees that can inflate your bill.
Why Are Mounjaro Prices Increasing in the UK?
Several factors are driving the upward trend. High demand — particularly for maintenance doses — combined with limited manufacturing capacity has pushed prices higher. Online pharmacies with lower overheads have mitigated some of the increase, but the market overall has seen a 5–10% rise since late 2025.
Supply chain and demand factors
Eli Lilly, the manufacturer, controls global supply. A surge in prescriptions during 2024–2025 led to periodic shortages, which in turn caused spot price increases at both high‑street and online pharmacies. Higher doses (10mg–15mg) are especially prone to supply constraints, explaining their steeper price tags.
Regulatory pricing changes in the UK
The UK’s private prescription model gives pharmacies freedom to set their own prices, but NHS widening of access to tirzepatide could eventually put downward pressure on private costs. For now, no regulatory cap exists, and prices are determined by market competition.
Price history and future projections
From launch in December 2023 at around £150 for 2.5mg, prices dipped slightly in mid‑2024 to £130–£200, then climbed again as demand intensified. As of May 2026, the range spans £120–£340, with online pharmacies offering the most competitive rates. Future pricing will likely depend on whether Eli Lilly introduces a UK savings program or new competitors enter the market.
Competing GLP‑1 drugs such as retatrutide and oral formulations are in late‑stage trials. If approved, they could force Mounjaro prices down. Similarly, any NHS bulk‑purchase agreement would create a price ceiling for the private market. Monitor MHRA alerts for safety updates.
Can I Get a Mounjaro Savings Card or Discount in the UK?
Unlike the US, the UK does not have a widely advertised patient savings card from Eli Lilly. However, several pharmacies run their own discount programmes or loyalty schemes. The key is to look for pharmacy‑specific codes rather than manufacturer coupons.
Eli Lilly UK patient assistance programs
Eli Lilly’s UK arm has not announced a patient assistance programme comparable to the US savings card. The Eli Lilly UK website currently directs patients to private providers and the NHS. No official discount card has been confirmed as of May 2026.
Pharmacy-specific loyalty discount codes
Some online pharmacies, such as WePrescribe, publicise discount codes (e.g., “10% off”). Others offer reduced rates for returning customers. Monj’s price tracker often flags active promotions, but these deals can change quickly and may apply only to the first month.
Subscription models for recurring Mounjaro supply
A handful of providers offer subscription plans that bundle consultations and delivery at a fixed monthly rate. While convenient, these can lock you into a single pharmacy and may not be the cheapest option once your dose increases. Always compare the subscription total against paying per pen elsewhere.

Why Is Mounjaro Pricing So Volatile in the UK?
High demand combined with limited supply drives up prices, especially at higher doses. Online pharmacies, which have lower overheads, pass savings on to consumers, while Boots and Lloyds use a premium pricing model targeting convenience. Independent comparison sites such as Monj create price transparency, encouraging patients to reassess their buying source every three months for the best deal.
Which Price Comparison Sites and Pharmacies Are Most Trustworthy for Mounjaro Costs?
“Live-tracked pricing from verified GPhC pharmacies. Full costs incl. consultation & delivery.”
Monj.co.uk, independent price tracker
“Monthly costs range from approximately £120 to £340 depending on dose and pharmacy.”
The Care Pharmacy, pricing guide
“Prices start from £128–£280 for the 2.5 mg or 5 mg starter pens.”
MedEazy, pricing page
For the most up‑to‑date and complete cost picture, the independent tracker Monj: Mounjaro Price Comparison UK remains the most transparent source. Always verify any savings claims against the NHS Tirzepatide information page and check the General Pharmaceutical Council (GPhC) register before purchasing.
What Can We Expect for Mounjaro Pricing in the Near Future?
The next 12–18 months could bring significant changes. A potential price war between online pharmacies, the introduction of UK‑specific savings programmes by Eli Lilly, and the arrival of new competitors such as retatrutide or oral GLP‑1 drugs may all pressure Mounjaro prices downward. For now, the best strategy is to compare prices every few months and consider switching pharmacies per dose. For a broader comparison, see our Mounjaro vs Ozempic: Weight Loss Comparison.
