"So impressed with my consultation and follow ups. I think the way you can actually see your consultant via the video call is so good and feels like you’re actually in a clinic. The advise and management of the injections is amazing and I’ve already lost 1stone 2lb by following the advise and using the injections. I would highly recommend this 😊"

Frequently asked questions

Calleva Clinic is a regulated GP practice led service, not an online pharmacy. That means:

You’re assessed by qualified clinicians, not just asked to fill a basket. We offer medical consultations to review your health, goals, and treatment suitability.

Prescriptions are issued after clinical review, never automatically. We follow UK regulations for safe prescribing and supply of weight loss medications.

You receive ongoing support, including dosage guidance, side effect monitoring, and follow-up care — not just a parcel in the post.

Your treatment is tailored to you, based on your medical history, clinical needs, and long-term goals.

Online pharmacies typically dispense pre-prescribed medications. Calleva Clinic provides end-to-end medical care — from consultation to prescription, supply, and supervision.

You only pay for the weight loss injections — everything else is included.

This includes a no-obligation initial video consultation, follow-up video consultations, personalised coaching, secure UK delivery if not local to our practice, and monthly dose adjustments with your assigned clinician.

No hidden fees. No referral needed. Just safe, structured support from a UK-regulated, GP practice led clinic.

We offer free, secure home delivery for your weight loss injections across England. Your medication is shipped with temperature-controlled packaging to ensure safety. Once received, store it in the fridge between 2°C and 8°C. After first use, Mounjaro can be kept at room temperature for up to 30 days, and Wegovy for up to 6 weeks. Delivery is tracked, and you'll get a time window on the delivery day. If you're local, you can also collect in person at your convenience.

Weight loss injections like Wegovy® or Mounjaro® are available on the NHS, but only for a small number of patients with the highest clinical need, under strict eligibility criteria:

BMI over 40, or over 37.5 for people from South Asian, Chinese, other Asian, Middle Eastern, Black African, or African-Caribbean backgrounds AND

At least four of the following health conditions:

Type 2 diabetes
High blood pressure (requiring medication)
Cardiovascular disease (e.g. heart disease, stroke)
Obstructive sleep apnoea (confirmed by a sleep study)
High cholesterol or triglycerides (diagnosed or treated)

Must agree to and attend a wrap-around support programme.

If you prefer more flexibility or faster access, private treatment may be an option. Calleva Clinic offers regulated, GP practice-led care without the need to join an external programme.
