If you have recently started prescribed medical cannabis, a treatment review is the normal next step. It is not a test, and it is not a sign that you have done anything wrong. It is a planned check-in so your prescriber can understand how the treatment is going, whether side effects are causing problems, and whether the current plan still makes sense for you.
UK medical cannabis is specialist-led. That means the clinic needs real information from you after treatment starts, not just the notes from the first appointment. A review gives you a structured place to explain what has helped, what has been difficult, and what practical problems have come up with the prescription, pharmacy or product.
The exact timing varies by clinic. Some patients are reviewed after the first prescription or early in treatment, while others move into a less frequent review rhythm once things are stable. If you are unsure what your clinic expects, ask them directly rather than guessing.
What the review is trying to answer
A treatment review is mainly there to answer four questions.
First, is the treatment still suitable for you? Your prescriber may ask about symptoms, day-to-day function, sleep, mood, alertness, side effects, and whether anything important has changed in your health.
Second, are there safety concerns? This can include drowsiness, anxiety, dizziness, impairment, interactions with other medicines, new diagnoses, pregnancy or breastfeeding, mental-health changes, or anything else that may affect suitability.
Third, are you able to follow the treatment plan as it was prescribed? If label wording, device use, oil timing, pharmacy instructions or repeat admin is unclear, say so. The useful action is not to guess, but to ask the clinic or pharmacy to clarify.
Fourth, is the practical side working? Reviews can also cover stock issues, delivery delays, affordability, packaging, prescription wording, or whether you know who to contact between appointments.
When to contact the clinic before a scheduled review
You do not have to wait for the next review if something feels wrong or unclear. Contact your clinic, pharmacist or usual care route sooner if:
- side effects feel worrying, persistent or hard to manage;
- you feel unusually drowsy, anxious, confused or impaired;
- you are unsure how to use the prescribed product or device;
- another medicine has been started, stopped or changed;
- your health, diagnosis or risk factors have changed;
- the label, product, repeat prescription or delivery process is unclear;
- you think you may have taken more than intended;
- you are considering a change to the treatment plan.
Some clinics, pharmacies or medicine flows may also use questionnaires or check-in forms to ask about effects after dispensing. Treat those as another way to report what is happening, not as a replacement for contacting the clinic if you are concerned.
What to prepare before the review
You do not need to create a huge file. A few clear notes are usually more useful than a complicated spreadsheet.
Useful things to bring or have ready include:
- the product name, strength and form from the pharmacy label;
- the date you started and any dates when things changed;
- the main symptoms or goals you discussed at the first appointment;
- side effects, including when they happen and how long they last;
- any drowsiness, anxiety, dizziness or impairment concerns;
- current medicines, supplements and any recent changes;
- pharmacy, stock, repeat or delivery problems;
- questions you want answered before the next prescription or review.
If you already keep private stock, usage or side-effect notes, bring the parts that are useful. The review is not about proving you have tracked everything perfectly. It is about giving the prescriber enough practical information to make a safer decision.
What might happen after a treatment review
After a review, the prescriber may decide that the current plan should continue, that more information is needed, or that a clinical change should be considered. They may also explain side effects, ask you to monitor something more closely, update follow-up timing, or direct a pharmacy question back to the dispensing team.
The important boundary is simple: do not change product, route, timing or amount on your own. If something is not working, the review is the place to discuss it with the prescriber. Medical cannabis can be useful for some suitable patients, but suitability and monitoring still depend on individual assessment.
What to ask your clinic or pharmacy
- When is my next review, and how will it happen?
- What should I record before that appointment?
- Who should I contact if side effects appear between reviews?
- What should I do if the pharmacy cannot supply the prescribed product?
- How do I report a problem with the label, device, oil bottle or delivery?
- Has anything in my medicines list changed the safety picture?
- What would make you want me to contact the clinic sooner?
These questions keep the decision with the clinical team while making sure you are not left guessing between appointments.
What this guide cannot decide for you
This guide cannot tell you whether your current prescription should continue or whether your treatment plan should change. It also cannot tell you how often your clinic will review you. Different clinics have different processes, and your prescriber has to judge your situation, records, side effects, other medicines and risk factors.
If you have severe symptoms, feel unsafe, or think you need urgent medical help, use NHS 111, 999, A&E or your clinic’s urgent instructions as appropriate.
