How to compare weight loss treatment prices

Two pharmacies can show the same headline price and charge different totals over a few months. This checklist keeps the comparison fair.

By GLP IndexPrices refreshed How we check prices

Compare the delivered total, not the headline price. Then check the ongoing price for month two onwards, the price at the dose you will move to, any live code and the pharmacy registration.

The checklist

  1. Use delivered totals. Postage can add several pounds. Every first order and ongoing price on GLP Index includes delivery.
  2. Read the ongoing price. A low first order can hide a high month two. See first order vs ongoing.
  3. Price the doses ahead. Prices rise with each step. See how price rises with each dose step.
  4. Add up the months. The comparison pages total the first three months and a full year.
  5. Look for a code. The codes section lists live codes and who can use each one.
  6. Check the registration. See how to check a pharmacy.
  7. Confirm at checkout. Prices change without notice. The total on the checkout page is the price you pay.

Where to start

GLP Index compares prices and gives no medical advice. These are prescription only medicines. A UK prescriber decides whether a treatment and a dose suit you. Confirm the total at checkout before you pay.

Questions

What should a fair comparison include?

The delivered total, the ongoing price, the dose you are on and whether a code applies. GLP Index shows all four.

Is the cheapest pharmacy always the best choice?

Price is one factor. Check the registration, the delivery method and the ongoing price before you order.

Can I switch pharmacy later?

Many people do. A new pharmacy will ask for your history and a prescriber will review your answers.
