About Zerenia
Zerenia has established a substantial presence in the UK medical cannabis sector, distinguishing itself through a combination of physical clinic locations and online video consultation services. This multi-channel approach gives patients the option of attending in person — an important consideration for those who prefer face-to-face clinical interaction — as well as the convenience of a remote appointment.
The clinic works with a team of GMC-registered specialist clinicians and covers a broad range of qualifying conditions. Zerenia's self-referral pathway means patients can book directly without first obtaining a GP referral, though having supporting documentation from a GP or treating specialist will always strengthen an application.
Medication costs at Zerenia are reported to be approximately £2 to £10 per day for many patients, though actual costs vary considerably depending on the prescribed product, formulation, and individual dosing requirements. Patients should discuss ongoing medication costs with their specialist and verify current pricing directly with the clinic at the time of booking.

How the Zerenia Patient Process Works
1. Self-referral and eligibility check: Patients can refer themselves directly to Zerenia without a GP letter, though supporting medical documentation is recommended. Complete an initial screening to assess whether your condition and treatment history are likely to qualify.
2. Choose your consultation format: Zerenia offers both in-person appointments at their clinic locations and video consultations for patients who prefer or require a remote option. Select the format and location most suitable for you.
3. Specialist consultation: A GMC-registered specialist conducts a thorough clinical assessment covering your medical history, the treatments you have previously tried and their outcomes, and your current symptoms. Consultations are typically available within two to five working days of booking.
4. Prescription decision: If the specialist considers a cannabis-based medicine clinically appropriate, a Schedule 2 prescription is issued. If not, the specialist will explain the clinical reasoning.
5. Dispensary and delivery: Prescriptions are fulfilled through licensed UK pharmacies. Medication is typically delivered to your home within a few working days of the prescription being issued.
Zerenia Consultation and Medication Costs
- Initial specialist consultation: Approximately from £99 — verify current pricing directly with Zerenia at the time of booking
- Follow-up appointments: Priced accordingly — check current rates with the clinic
- Monthly medication: Typically approximately £60 to £300 per month (approximately £2–10 per day), varying significantly by product, formulation, and individual dosing requirements
Zerenia's full-service prescribing model means the ongoing cost of care includes both the consultation fee and the medication. Patients should discuss the expected total monthly cost with their specialist before committing to treatment.
Zerenia Review 2026 — What UK Patients Report
Patient experience at Zerenia has been broadly positive, particularly among those seeking an accessible and efficient route to a legal medical cannabis prescription. The following reflects common themes from UK patient accounts and independent reviews — not sponsored content.
- Speed and access: The 2–5 day appointment window is consistently highlighted. For patients who have been waiting months through NHS routes, this is a significant advantage. Online booking is straightforward.
- Self-referral pathway: Patients frequently cite the absence of a GP referral requirement as a practical benefit. Many had been unable to obtain GP support for medical cannabis and found the self-referral model genuinely valuable.
- In-person option: The availability of physical clinic locations in London, Manchester, and Birmingham is highlighted by patients who wanted face-to-face clinical interaction rather than a video-only service.
- Condition breadth: Patients with ADHD, anxiety, and PTSD — conditions less well-served by some pain-focused clinics — report that Zerenia's psychiatry-informed clinical model is better suited to mental health presentations than alternatives.
- Variable experience by location: Some reviews note that the quality of the consultation can vary between individual clinicians. As with any multi-clinician clinic network, the experience of the individual prescriber matters.
- Ongoing costs: A common practical consideration is the cumulative cost of follow-up appointments alongside medication. Patients are advised to ask about the follow-up schedule and total ongoing cost before committing.
