Mounjaro Discount Codes: How to Save Money on Treatment

When it comes to managing their weight, UK Mounjaro patients have taken to it where other strategies haven’t worked.

But it’s an investment. And the cost of Mounjaro has recently increased in the UK. (This followed Eli Lilly’s decision to raise its wholesale price in September.) So, you’re probably hunting down the best deal on treatment.

Fortunately, many providers offer discounts, which can help save on Mounjaro. Here’s how they work, how different providers’ discount codes compare, and other ways to save on weight care treatment long-term.

How Do Discount Codes Work?

How discount codes work will vary from provider to provider.

For example, some online pharmacies offer a percentage off (e.g. 20%) your first month, whereas others offer a fixed amount of money (e.g. £40) off your first order or online consultation. 

Other providers offer loyalty schemes, where you can save more the more your shop with them.

At Simple, we have a loyalty-based scheme. When you place an order, you will be given a unique code. If a new patient uses that code, they’ll get £40 off their first order, and you will receive £40 credit to your account. Jump to the section below for more details.

How Can I Get Mounjaro For Free?

If you’re struggling to afford treatment, you can get Mounjaro on the NHS. If you live in England, you’ll have to pay the prescription charge (currently £9.90).

However, waiting lists for treatment are long and availability depends on where in the UK you live. The NHS has a higher BMI threshold than private providers. You typically won’t be eligible for Mounjaro on the NHS if your BMI is under 35.

You won’t have to wait as long if you choose to get Mounjaro with a private prescription.

Other Ways to Save on Weight Care Treatment

If you’re struggling to meet the cost of Mounjaro, there are more affordable options.

Move to Wegovy

Like Mounjaro, Wegovy is a highly effective GLP-1 weekly injection for weight management. Clinical trials show patients on the highest dose can lose 17% of their starting body weight over 68 weeks. 

It works similarly to how Mounjaro works. It mimics the GLP-1 hormone, which controls appetite. It slows down the rate food leaves your stomach and helps you with feeling fuller for longer. Side effects of Wegovy are similar to side effects of Mounjaro.

The cost of Wegovy is typically much lower. At Simple, you can buy Wegovy, with cost starting at £99. That’s £50 cheaper than the Mounjaro starting dose.

Switch to a Lower Mounjaro Dose

The lower doses of Mounjaro less of a cost than the higher doses. So, you might want to consider moving down a dose to save some money. This could be an attractive option if you’re looking to maintain weight on a lower maintenance dose.

Consider Other Weight Care Treatments

Other weight loss treatments are available:

• Nevolat Liraglutide is another GLP-1 weight loss medication. While you inject Mounjaro and Wegovy once a week, you inject Saxenda once a day. The cost of treatment starts at £69.

• Orlistat is a weight loss pill you take three times a day alongside your meals. Unlike Mounjaro or Wegovy, it’s not a GLP-1. Instead, it works by removing the amount of fat you eat by around 30%. A pack of 42 capsules costs £17.50.

Key Takeaways

• Discounts Differ by Provider: Some cut a fixed amount of money; others give a percentage off. Check limits (first order only, consultation-only, or across doses).
• NHS vs Private: NHS may be cheaper if you’re eligible, but access varies and waits are long. Private prescriptions are faster but depend on provider pricing.
• Other Ways to Save: Consider Wegovy (often lower cost). Or try stepping down to a lower Mounjaro dose if clinically appropriate. You can also use alternative approved treatments. The best option will depend on where you are on your weight loss journey.
• Refer a Friend: With Simple Online Pharmacy, you can earn £40 credit to your account for every new patient who uses your referral code, with each new patient also saving £40 on their order.
