What You Get for the Price

A 5mg pack is one Mounjaro KwikPen holding four weekly 5mg doses, which is a 4-week supply. It's sent in temperature-controlled packaging and should be kept in the fridge at 2–8°C until you start using it.

When Do You Move to 5mg?

5mg is usually the second step. Most people start on 2.5mg for four weeks, then move up to 5mg if they're tolerating treatment. Some people stay on 5mg longer, or keep it as their ongoing dose, if it's working well for them. Your prescriber decides when to increase your dose, and whether to.

5mg vs 2.5mg: How Much More Does It Cost?

Moving from 2.5mg to 5mg adds £34 a month. If you later go up to 7.5mg, that's a further £41 a month.

The Cost of Staying on 5mg

If you stay on 5mg after your first month on 2.5mg, six months of treatment costs £1,019.99 in total: £124.99 for the first pen, then five 5mg pens at £179. That works out at about £170 a month on average.

Already on 5mg With Another Pharmacy?

You can switch to Cured Pharmacy and carry on at 5mg. In your consultation, tell us your current dose and when you took your last injection. The prescriber will check you can continue at 5mg and won't need to restart at 2.5mg. The £20 first-order discount applies to your first 5mg pen with us.
