What Is ZAVA?

ZAVA is an online doctor service operating across the UK and several European markets, providing assessment and prescription for conditions ranging from sexual health and general health to weight management. Prescribing is carried out by UK-registered doctors following a structured online assessment.

Its weight loss service is notable for breadth. Rather than offering only the two headline GLP-1s, ZAVA lists Mounjaro, Wegovy injections, the Wegovy pill, Nevolat (a daily liraglutide injection filling the gap left by Saxenda's long-term unavailability), and oral tablet treatments — with prices starting at £19.00 for the cheapest options.

ZAVA also explicitly supports patients restarting treatment or moving into maintenance, reviewing health, treatment history, current dose, and progress before deciding on suitability. That is a more clinically aware posture than "complete a form, receive a pen".

How ZAVA Works

1. Complete the online assessment. A structured questionnaire covering health, treatment history, and goals.
2. Doctor review. UK-registered doctors review your assessment against prescribing criteria.
3. Prescription and dispensing. Approved treatments are dispensed and dispatched.
4. Delivery. Standard and express options, with next-day delivery available.
5. Ongoing supply. Reorder with review of dose and progress; ZAVA supports restarts and maintenance transitions.

Medication Options and Pricing

Pro Tip: ZAVA's £99 Wegovy starting price is for the lowest-dose pen. The published UK list prices for Wegovy have been roughly £73.25 per pack for the 0.25 mg, 0.5 mg, and 1.0 mg strengths, £124.53 for 1.7 mg, and £175.80 for 2.4 mg — so your cost rises substantially as you titrate. Budget from the maintenance dose, not the starter.

ZAVA reports patients losing up to 22.5% of body weight based on a survey of over 2,000 of its own weight loss patients reporting results after three to six months. That is self-reported patient survey data, not a controlled trial, and the upper figure reflects the best responders rather than a typical outcome.

Check ZAVA Pricing

Weight loss treatments from £19.00, with Wegovy from £99.00 per pen. Prescribed by UK-registered doctors with next-day delivery available.

Eligibility, Providers, and Lab Requirements

ZAVA applies UK private prescribing criteria: BMI 30 or above, or 27 or above with a weight-related condition. Prescribing doctors are UK-registered, and the service operates under CQC and GPhC oversight applicable to UK online providers.

ZAVA's willingness to assess patients restarting treatment or transitioning to maintenance is clinically useful — many providers are geared only to new starts, leaving patients who paused treatment without a straightforward route back.

Contraindications follow the class: medullary thyroid carcinoma history, MEN2, pregnancy and breastfeeding, and hypersensitivity. See our eligibility guide.

Pharmacy Fulfilment and Shipping

Medication is dispensed and dispatched with standard or express delivery, including next-day options. Injection pens require refrigeration before first use, with defined room-temperature allowances afterwards.

ZAVA's European footprint means service specifics differ by country; the pricing discussed here is the UK service.

Ongoing Support, Nutrition, and Coaching

Support is clinical rather than programmatic:

• Doctor review at assessment and reorder
• Dose and progress review before continuing supply
• Support for restarting treatment or moving to maintenance
• Secure account messaging with the medical team
• Educational content on each medication

There is no coaching curriculum, dietitian, or habit programme. ZAVA is an online doctor service, and it prices accordingly. If behavioural support is what you need, Second Nature or Juniper UK bundle it.

Cancellation, Refunds, Insurance, and Costs

ZAVA operates on a per-order basis rather than a subscription, so there is nothing to cancel — you simply do not reorder. That is a meaningful advantage over multi-month plan providers for patients unsure how they will tolerate treatment.

Private prescriptions are self-funded. NHS access to tirzepatide follows separate criteria and is far cheaper where you qualify; ask your GP. Prescription medicines cannot generally be returned once dispensed.

Frequently Asked Questions

How much does weight loss treatment cost at ZAVA?

ZAVA publishes weight loss treatments from £19.00, with Wegovy from £99.00 for one pen, which is four doses or four weeks of treatment. Mounjaro and other options are priced by dose. Costs rise as you titrate to maintenance.

What weight loss medications does ZAVA offer?

Mounjaro (tirzepatide), Wegovy (semaglutide) injections, the Wegovy pill, Nevolat (a daily liraglutide injection), and oral tablet treatments.

Is there a cheaper generic version of semaglutide?

No. ZAVA states that semaglutide is available under its brand name Wegovy and that there is currently no cheaper generic version available in the UK.

Can I switch from Mounjaro to the Wegovy pill?

ZAVA's guidance indicates that patients taking 7.5 mg or higher of Mounjaro injections can usually switch to the maximum maintenance dose of the Wegovy pill. Whether a switch suits you is a decision for your prescribing doctor.

Does ZAVA support restarting treatment?

Yes. ZAVA states its doctors review health, treatment history, current dose, and progress before deciding on suitability, and that patients can come to ZAVA to restart treatment or move into maintenance.

Is ZAVA available outside the UK?

ZAVA operates across several European markets. Service specifics, available treatments, and pricing differ by country; the figures here are for the UK service.

Bottom Line

ZAVA is the most flexible mainstream online doctor route to weight loss treatment in the UK. Low entry pricing, no subscription, an unusually wide medication range including oral and daily options, and explicit support for restarts make it a practical choice for patients who want clinical oversight without a programme wrapper.

Strengths: low entry pricing, wide medication range, no commitment, UK-registered doctors, restart and maintenance support, fast delivery.

Drawbacks: no behavioural support, steep dose-escalation costs, self-reported outcome marketing, and variability across European markets.

Best for: self-directed UK patients who want clinician-reviewed access on their own terms.

Skip if: you want coaching built in, or you may qualify for NHS treatment.

If you are unsure how you will tolerate a GLP-1, a per-order service beats a six-month plan. You can always commit later; you cannot easily un-commit.

US readers: CoreAge Rx offers all-in monthly pricing from $179–$399 including medication and provider messaging, with 12–24 hour approvals. Save up to $200 on your first three months.
