Why this matters

If you are prescribed medical cannabis in the UK, your repeat prescription is not automatic. Unlike some NHS repeat scripts, private clinics and pharmacies need you to request each repeat, often within a specific window. Leaving this to the last minute can mean gaps in your supply, especially when stock changes, payment delays, or pharmacy processing times come into play.

Planning ahead helps you avoid that admin stress. This guide explains the practical steps you can take, based on how clinics and pharmacies typically work. It does not promise that any clinic or pharmacy will process your request within a certain time, or that your chosen product will always be available.

The key is to understand your own clinic’s process, your pharmacy’s lead times, and the realistic timeline from request to delivery. For more on the wider picture of stock changes and pharmacy delays, see our guide on repeat prescriptions, stock changes and pharmacy delays.

When should I request my repeat?

Most private clinics have a window during which you can request a repeat prescription. This is often around 7 to 14 days before your current supply is due to run out. Requesting too early may mean the prescriber cannot issue a new prescription because your current one is still valid. Requesting too late risks a gap.

Check with your clinic directly. Some clinics allow you to request repeats through an online portal or by email. Others may require a follow-up consultation before they issue a new prescription. The General Medical Council (GMC) guidance on cannabis-based products for medicinal use (CBPMs) emphasises that prescribing decisions should be made on a case-by-case basis, so your clinician may need to review your response to treatment before issuing a repeat.

A practical approach is to set a calendar reminder for when your clinic’s request window opens. If you are unsure of the window, ask your clinic’s patient support team. They should be able to tell you the earliest and latest dates you can submit a repeat request.

Stock changes, payment timing, and pharmacy processing

Even after your prescription is issued, several steps can cause delays. These are worth factoring into your planning.

Stock changes: Pharmacies do not always hold every product in stock. If your prescribed product is out of stock, the pharmacy may need to order it, or your clinician may need to prescribe an alternative. This can add days to the process. The Care Quality Commission (CQC) expects providers to have arrangements in place for the safe supply of CBPMs, but stock availability is not promised.

Payment timing: Most private pharmacies require payment before they dispatch your medication. If you pay by bank transfer, the payment may not clear immediately. If you pay by card, check whether the pharmacy processes payments on weekends or bank holidays. Some pharmacies will not dispatch until the payment has fully cleared.

Pharmacy processing and delivery: Once the pharmacy receives your prescription and payment, they need to prepare and check your medication. This can take one to three working days, sometimes longer. Delivery times then depend on the courier service used. Some pharmacies offer tracked delivery, but this does not promise a specific arrival time.

What to keep in your records

Keeping your own records can help you track your repeat cycle and avoid last-minute surprises. You might note down:

  • The date you last requested a repeat
  • The date the prescription was issued
  • The date you paid the pharmacy
  • The date the medication was dispatched and delivered
  • Any stock changes or product substitutions

This is not a substitute for clinical records, but it can help you spot patterns. For example, if your pharmacy consistently takes three working days to dispatch, you can factor that into your planning. For more on what to keep, see our guide on what to keep in your medical cannabis records.

If you use a private records or stock-tracking tool, you can use it as a personal note of your usage and stock levels. This is a practical aid, not a clinical tool, and does not replace communication with your clinic or pharmacy.

What to ask your clinic or pharmacy

  • What is the earliest and latest date I can request a repeat prescription?
  • Do I need a follow-up consultation before a repeat can be issued?
  • How do I submit a repeat request (portal, email, phone)?
  • What happens if my prescribed product is out of stock?
  • How long does the pharmacy typically take to process and dispatch?
  • What payment methods do you accept, and how long does payment clearance take?
  • Do you offer tracked delivery, and what courier do you use?
  • Is there a cut-off time for same-day dispatch?

These questions are for information only. They are not advice to ask your clinic about your treatment plan, product, route, or timing without your clinician’s direction.

What this guide cannot decide for you

This guide cannot tell you exactly when to request your repeat, because every clinic and pharmacy has its own process. It cannot promise that your prescription will be issued, that your product will be in stock, or that delivery will arrive on a specific date. It cannot promise that a repeat will be issued.

Medical cannabis is prescribed on a case-by-case basis. Your clinician will decide whether a repeat is appropriate based on your individual circumstances. The NHS, NICE, and GMC all emphasise that prescribing decisions should be made by a specialist clinician, and this guide does not override that.

If you are unsure about any part of your repeat process, contact your clinic or pharmacy directly. They are best placed to give you accurate, up-to-date information.
