What tirzepatide is
Tirzepatide is a once-weekly injection that acts on two gut hormone receptors, GIP and GLP-1. Eli Lilly sells it as Mounjaro. In the US, Mounjaro is approved to improve blood sugar control in type 2 diabetes, alongside diet and exercise. In some countries, including the UK, Mounjaro is also licensed for weight management.
The KwikPen is a multi-dose prefilled pen: one pen holds four weekly doses of the same strength.
How the dose is built up
| Label dose | |
|---|---|
| Weeks 1 to 4 | 2.5 mg once a week, to get used to it |
| Then | 5 mg once a week |
| Going up | In 2.5 mg steps, at least 4 weeks on each dose |
| Maximum | 15 mg once a week |
| Missed dose | Take it within 4 days; after that, skip it and keep to your usual day |
We stock 5 mg and 15 mg pens only, not the 2.5 mg starting dose. The 15 mg pen is the highest dose on the label and is not a starting dose.
Side effects and warnings
In the US diabetes trials, the most common side effects at 5 mg were nausea (12% against 4% on placebo), diarrhoea (12% against 9%), indigestion (8% against 3%), constipation (6% against 1%), stomach pain (6% against 4%), less appetite and vomiting (5% each). They were more common at higher doses: at 15 mg, 18% had nausea.
Do not use tirzepatide if you or anyone in your family has had medullary thyroid cancer, or if you have multiple endocrine neoplasia type 2 (MEN 2). It caused thyroid tumours in rats; whether it does in people is unknown. Tell a doctor about a lump in the neck, trouble swallowing or a hoarse voice that will not go away.
- Get medical help for severe stomach pain that does not go away, with or without vomiting: it can be pancreatitis.
- With insulin or a sulfonylurea, blood sugar can drop too low. Your doctor may change those doses.
- Vomiting and diarrhoea can dry you out and harm the kidneys. Drink enough.
- Birth control pills may work less well: use a non-oral method, or add a barrier method, for 4 weeks after starting and after each dose increase.
- Tell your doctor if you are pregnant or plan to be, and before any surgery with anaesthesia.
Storing the pen
- Before first use, keep pens in the fridge at 2 to 8°C. Do not freeze them, and do not use a pen that has been frozen.
- A pen can be kept at room temperature up to 30°C for up to 30 days.
- After the first injection, throw the pen away after 30 days or after four doses, whichever comes first.
