If you are trying to order Mounjaro 5mg and want to know whether it is available, this page explains the current UK availability picture, how to plan your next order, and what to do if your pharmacy cannot supply your next pen.
Stock can change, so no pharmacy can guarantee that a particular strength will always be available. What you can do is plan your orders in advance and check availability before you need your next pen.
Is Mounjaro 5mg In Stock in the UK?
Tirzepatide supply in the UK has largely stabilised following the shortages reported in 2023 and 2024. However, availability can still vary between pharmacies and strengths. An individual pharmacy may also be temporarily out of a particular strength.
A couple of things are worth knowing specifically about 5mg:
- During the earlier shortages, the higher strengths, including 7.5mg and above, were generally more affected. Lower strengths such as 5mg were generally less affected. However, previous supply patterns do not guarantee current availability.
- Availability can change. The most reliable way to check whether 5mg is available from a particular pharmacy is to check at the time you place your order. If there is a delay, the pharmacy should let you know and explain the next steps.
If you have searched for a Mounjaro stock checker, there is no single national live tool that reliably shows which pharmacy has each strength available in real time. Checking directly with the pharmacy is usually the most practical way to confirm current availability.
How to Avoid a Gap in Your Treatment
One simple way to reduce the risk of running out is to plan your next order before you use your final dose.
- Each pen is designed to deliver four weekly doses, so you can plan ahead for when you will need your next pen.
- Consider ordering your next pen around one week before your current pen runs out. This gives you some extra time for the clinical review, prescription, delivery, or a temporary stock issue.
- If you are moving to a different strength, allow enough time for your prescriber to review the dose change and for the new pen to be supplied. Mounjaro treatment usually starts at 2.5mg once weekly, with increases considered by the prescriber based on your response and tolerability.
Planning ahead can make things much easier than waiting until your final dose and then trying to find a pen urgently.
What to Do If You Are Out of Stock
If your pharmacy, ours or another pharmacy, cannot supply your next pen, do not panic. There are a few sensible steps you can take.
First, contact your prescriber
If you are in the middle of treatment and cannot obtain your next pen, contact your prescriber or pharmacy first. They can advise you based on your individual treatment plan and explain what to do if there is likely to be a delay.
Do not change your dose or restart treatment yourself just because a particular strength is unavailable. This is especially important if you also take medicines for diabetes, as changes to your Mounjaro treatment may affect blood glucose management.
If you are approaching your next injection and cannot obtain your usual pen, ask your prescriber what to do rather than trying to make up a dose or using a different strength without medical advice.
If You Have to Miss a Dose
If you miss a dose, do not try to make up for it yourself. Follow the instructions in the patient information leaflet or speak to your prescriber or pharmacist if you are unsure what to do.
- Do not double up to catch up on a missed dose. If a dose is more than 4 days late, the usual advice is to skip it and take your next dose on your regular day. Never take two doses within 3 days of each other.
- Do not stretch a pen or extract leftover medicine to make it last. The leftover liquid is not intended to be used as an additional dose.
- A longer gap may mean your treatment needs to be reviewed. If you have missed several weeks, speak to your prescriber before restarting. Depending on how long you have been without treatment and your individual circumstances, your prescriber may consider restarting at a lower strength rather than going straight back to 5mg.
Stopping tirzepatide does not usually cause withdrawal symptoms. However, if treatment is stopped for a longer period, its effects on appetite and weight may reduce, and some people may regain weight over time. Keeping up healthy eating and physical activity habits can continue to support your weight management during a break. If you have been off Mounjaro for several weeks, speak to your prescriber before restarting so they can advise you on the appropriate dose.
Switching Pharmacy or Transferring Your Prescription
If your current pharmacy cannot supply your usual strength, you can consider another legitimate pharmacy. With a private prescription, you are not necessarily tied to one pharmacy.
If you want to move to us, you will need to complete an online consultation as a new patient. You will still need an appropriate clinical assessment and a prescription from a UK registered prescriber. It is helpful to tell the prescriber what strength you have been taking, how long you have been taking it, when your last injection was, and any side effects you have experienced. This information can help the prescriber decide whether the same strength remains appropriate for you.
A private prescription cannot simply be transferred in the same way as an NHS prescription. You will generally need a new assessment and prescription from the pharmacy or prescribing service you choose. This helps ensure that your current treatment is reviewed before another supply of this prescription only medicine is provided.

About Mounjaro 5mg
5mg is the second step in the Mounjaro dosing schedule, usually reached after the 2.5mg starting strength. Treatment can be increased gradually up to 15mg once weekly if your prescriber considers a higher dose appropriate based on your response and tolerability. Some people may remain on 5mg if it continues to be suitable for them. For more information about what to expect when moving up to this strength, see our Mounjaro 5mg guide.
Mounjaro (tirzepatide) is made by Eli Lilly. It acts on two gut hormone receptors, glucose dependent insulinotropic polypeptide (GIP) and GLP 1. This can affect appetite, feelings of fullness and stomach emptying. For some people, 5mg may remain an appropriate dose, while others may move to a higher strength if their prescriber considers this suitable. It is licensed for weight management alongside a reduced calorie diet and increased physical activity. Clinical trials have found that tirzepatide can support significant weight loss when used alongside lifestyle changes, although individual results vary. Mounjaro is also licensed for the treatment of type 2 diabetes.
Is 5mg enough of Mounjaro for weight loss?
It can be an appropriate treatment strength for some people, but there is no single dose that works the same way for everyone. Your response is assessed over time, including factors such as changes in your weight and how well you tolerate the medicine.
Some people may remain on 5mg if their prescriber considers it suitable, while others may need a higher strength as part of their treatment plan. A higher dose does not guarantee faster or greater weight loss. Your prescriber can review your progress and decide whether staying on 5mg or changing the dose is appropriate for you.
Eligibility
For weight management, Mounjaro is licensed for adults with a BMI of 30 or above, or a BMI of 27 or above where at least one weight related health condition is present. These conditions can include high blood pressure, dyslipidaemia, obstructive sleep apnoea, cardiovascular disease, prediabetes or type 2 diabetes. NHS access is separate from private prescribing and is subject to specific eligibility criteria, which may vary according to local arrangements and current clinical guidance.
Mounjaro should not be used during pregnancy. If you are breastfeeding, trying to conceive, or have a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia type 2, have previously had pancreatitis, have certain digestive conditions, or are under 18, your prescriber will need to consider whether treatment is appropriate.
Common side effects of Mounjaro include gastrointestinal symptoms such as nausea, diarrhoea, constipation, vomiting and indigestion. These effects can be more noticeable when starting treatment or increasing the dose and may vary from person to person.
Injection site reactions such as redness, itching or swelling can also occur. Severe or persistent abdominal pain may be a sign of a more serious problem, such as pancreatitis, and requires prompt medical assessment. If you develop severe symptoms or signs of a serious allergic reaction, seek urgent medical advice.
Treatment suitability, and the strength prescribed, depend on an individual clinical assessment. Our guide to prescription weight loss treatments covers the wider options.
