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.
Our free video consultations are designed to be convenient and accessible. You can book a free personalised video consultation with our expert clinicians to discuss your health concerns and treatment options from the comfort of your home.
Results vary, but many patients start to see weight loss within the first few weeks. Significant weight loss is usually observed over several months with consistent use and lifestyle changes.
Common side effects include nausea, diarrhea, constipation, and injection site reactions. Most are mild and temporary. Our clinicians will discuss all potential side effects with you during your consultation.
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:
