Mounjaro Clicks Chart PDF: What It Is and What to Use Instead (November 2026)

01 · The short version

Is there an official Mounjaro clicks chart?

No, there is no official clicks chart. The Mounjaro KwikPen is set by turning the dose knob until the dose indicator shows the correct dose in the window. You confirm the dose by the number in the window, never by counting clicks.¹

Each pen is made for one strength. A 5mg pen is for the 5mg dose, a 10mg pen for the 10mg dose, and so on. Your prescriber chooses the strength, and the pen is built to deliver it. There is no reason to work out a click count for a standard dose, because the window already tells you.

Some people want a tool for counting clicks to take a smaller amount than the pen is designed to deliver. Others simply want reassurance that they dialled correctly.

02 · What to do

What to do instead of counting clicks

Dial until the window shows your prescribed dose, then follow the pen's own instructions for injecting. If the number in the window matches the dose on your prescription label, you have set the pen correctly. The pen will not let you dial past the medicine left inside.¹

If something looks wrong, such as a window that will not reach the right number, do not improvise. Contact the pharmacy or your prescriber. Our weight loss clinic team can talk through any pen question during support hours, and monthly reviews are part of ongoing care.

03 · Why counting clicks is unreliable

Why counting clicks is the wrong method

Counting clicks is unreliable because the licensed instruction is to read the number in the window. Clicks are a by-product of the mechanism, not a measuring system that has been tested and approved for dosing.

Several things can go wrong when people count instead of reading. You can lose count when the knob turns quickly. You can miscount when distracted, or confuse the sound of the dial with the sound of the dose. A wrong count does not announce itself, and the result is a dose you cannot verify.

Online charts tend to disagree with each other and are not written by the manufacturer.

If you have seen a chart that claims one pen strength can stand in for another, treat it with caution. The pen strength you hold is the strength that was prescribed, and it is designed to deliver that dose through the window.

04 · Partial doses and pen strengths

Can you take a smaller dose from a bigger pen?

You should not try to take a smaller dose from a higher-strength pen. People ask questions such as how many clicks give 2.5mg on a 10mg pen, or 4mg on a 5mg pen, or 3.75 on a 5mg pen.

"Microdosing", meaning taking smaller or more spread-out doses than the pen is designed to deliver, is not licensed, not supported by the pen's design and not endorsed by any UK regulator.¹ Altering doses outside the licence means unknown dosing accuracy and no safety data.¹

The licensed route already starts low. Everyone starts Mounjaro on 2.5mg once a week. This starting dose is about letting your body adjust, not about weight loss itself.¹¹ After at least 4 weeks the dose increases to 5mg, and can then step up by 2.5mg at a minimum of 4-week intervals (7.5mg, 10mg, 12.5mg) up to a maximum of 15mg weekly, depending on how you respond and tolerate it.¹¹

If the concern is side effects at a new dose, your prescriber can hold a dose longer or step down within the licence.¹ That is a safer answer than a self-made dose, and it needs only a message to the prescribing team.

Our guide to safety and side effects around click charts goes into more depth on why this matters.

05 · Doses per pen and the last dose

How many doses are in a pen, and what about the last bit?

Each KwikPen contains four weekly doses.¹ That applies at every strength, so a 5mg pen holds a month of weekly doses at 5mg, and a 10mg pen holds a month at 10mg.

People often ask whether they can use a pen after the weekly doses have been used, or whether it is safe to squeeze out the last bit of medicine. The pen is built to stop you. It will not let you dial past the medicine left inside. If the window will not turn to a full dose, the pen does not contain enough for one and should not be used for a partial injection.¹

So the practical rule is simple. If you can dial your full dose, the pen has enough. If you cannot, stop, do not top up from another pen, and tell the pharmacy.

Planning your supply helps avoid the situation. Reorders re-check suitability and there is no auto-shipping, so order your next pen before the current one runs low. The Mounjaro pen page shows current pen strengths and prices, and all six strengths are in stock.

07 · Staying on 2.5mg

Is it safe to stay on 2.5mg?

Staying on 2.5mg is a decision for your prescriber, not something to settle yourself. The 2.5mg dose is the starting dose, chosen so your body can adjust.¹¹ It is not designed as the dose for weight loss itself.

The licensed dose ladder then steps up depending on how you respond and tolerate it. Many people settle at a maintenance dose of 5mg, 10mg or 15mg. Higher is not automatically better, and your prescriber will guide the right pace.¹¹

If you feel the dose increase is arriving too fast, say so. Holding a dose longer is something a prescriber can arrange within the licence.¹ That is different from making your own partial doses with a click chart.

For realistic expectations on pace, see our weight loss chart. Weight loss on Mounjaro is gradual by design. The first weeks on 2.5mg are an adjustment phase and losses are usually modest.⁴

08 · Storage, missed doses and routine

Storage, missed doses and keeping a routine

Good routine removes most of the worry that makes people reach for a click chart. Keep Mounjaro pens in a fridge at 2–8°C and never freeze them. Once in use, a pen can be kept out of the fridge at a temperature not above 30°C for up to 30 days after first use, and must then be thrown away.¹ Keep the pen cap on to protect it from light, and never use a pen that has been frozen.

Inject once a week, on the same day each week, at any time of day, with or without food.¹ If you miss a dose, take it as soon as you can within 4 days (96 hours) of the scheduled time, then carry on with your usual day. If more than 4 days have passed, skip the missed dose entirely and take the next one on your normal day. Never take two doses within 3 days of each other.¹

You can change your weekly injection day if needed, as long as at least 3 days (72 hours) have passed since your last dose.¹

09 · Getting help with your pen

Getting help with your pen

If a pen behaves oddly, the pharmacy that supplied it is the right first contact. Our support team is available Monday to Friday, 9am to 5pm, by email at support@everydaymeds.co.uk, through the account portal chat, or by phone on 0333 207 0413.

Ongoing monthly reviews, dose-titration and follow-up assessments are part of aftercare, along with side-effect support. Needles, a sharps bin and injection guidance are included with every order, and the free GLPTrackr app can help you log the date and dose of each injection so you never need to rely on memory.

If you notice a new symptom after any dose, discuss it with your prescriber. You can also report suspected side effects through the MHRA Yellow Card scheme.¹⁹

10 · Medical disclaimer

Important information

Mounjaro (tirzepatide) is a prescription-only medicine, supplied only after an online consultation reviewed by a GPhC-registered prescriber. It is used alongside a reduced-calorie diet and increased physical activity. Individual results vary. This page is information, not a substitute for medical advice.

11 · Serious side effects

Serious side effects: when to get help straight away

Serious side effects are uncommon but need urgent attention. Seek immediate medical help for: severe, persistent stomach pain that may spread to your back, with or without vomiting (possible pancreatitis); pain in the upper right abdomen, fever or yellowing of skin/eyes (possible gallbladder problems); or signs of a severe allergic reaction such as swelling of the face or throat and difficulty breathing. If you take insulin or a sulfonylurea alongside Mounjaro, watch for low blood sugar (shakiness, sweating, confusion) — your prescriber may need to adjust those medicines.¹
