Switching Weight Loss Providers: Wegovy, Mounjaro, Ozempic & Semaglutide — The Complete UK Guide
Struggling with delayed deliveries, sudden price hikes, patchy customer support, or you simply want face‑to‑face care for your weight loss injections? You’re not alone. More UK patients are switching weight loss providers — and sometimes also switching medications — between Wegovy, Mounjaro, Ozempic and Semaglutide to get better outcomes, fewer side‑effects, and reliable, local continuity of care.
At Gloucestershire Pharmacy & Clinic – Travel, Weight, Ear & Hair loss Clinic, we make switching simple, safe and fast. We’re based at 305 High St, Cheltenham GL50 3HW, open Monday–Friday 9 am–6 pm (Sat–Sun Closed). Call 01242 437910 or book online now. Our private weight loss shots plans start from £137–£250 per month.

Why People Switch Providers (and Sometimes Medications)
Common reasons UK patients move from online to in‑clinic (or between clinics):
Stock inconsistency & shipping delays (missed weekly injections = stalled progress).
Rising fees or hidden costs for “admin/dispensing”.
Little to no monitoring — no dose reviews, no side‑effect help, no diet support.
Confusion about dose escalation or how to transition from one GLP‑1 to another.
Plateaus (weight stalls) with no strategy offered to break through.
Desire for a trusted, local weight loss pharmacy (search “weight loss injections near me” and choose a clinic you can physically visit).
Moving city (e.g., from a London weight loss provider back to Cheltenham/Gloucestershire).
Online vs In‑Clinic: What Actually Works Best?
Online providers can be convenient — until they’re not. Online-only care sometimes means:
Slow replies when you’re sick or confused
Little control over which brand/dose you receive
Harder to troubleshoot side‑effects or technique
In‑clinic providers like Gloucestershire Pharmacy & Clinic deliver:
Face-to-face or same-day reviews
On-site injection training and pen technique refreshers
Structured titration to minimise GI side effects
Rapid prescriptions, local stock, and direct pharmacist access
Real human support for diet, sleep, plateaus, and cravings

Switching Between Medicines: Core Principles
Switching is individualised. Key considerations:
Half-life & washout: GLP‑1s have long half-lives; abrupt overlaps can amplify side-effects.
Equivalence: A patient on Ozempic 1 mg doesn’t automatically map to Wegovy 2.4 mg.
Tolerance: If GI symptoms were severe, we may re-start at a lower dose of the new agent.
Goals & comorbidities: Mounjaro (tirzepatide) may be considered where semaglutide plateaus, due to dual GLP‑1/GIP action.
NHS vs Private: Off‑label use (e.g., Ozempic for weight loss) vs licensed indication (Wegovy).
Wegovy ↔ Mounjaro (tirzepatide): When and How to Switch
Common reasons to switch from Wegovy → Mounjaro:
Weight loss has plateaued at Wegovy’s top dose (2.4 mg).
Seeking the dual GLP‑1/GIP mechanism for potentially deeper metabolic effects.
Unmanageable side effects at higher semaglutide doses (sometimes patients tolerate tirzepatide differently).
General approach (clinic-tailored):
Finish your current Wegovy dosing week.
Start Mounjaro at 2.5 mg the following week, or consider microdosing if sensitivity is high.
Titrate every 4 weeks (2.5 → 5 → 7.5 → 10 → 12.5 → 15 mg) as tolerated.
Switching back (Mounjaro → Wegovy):
Occurs due to availability, cost, or tolerance.
We often re-introduce semaglutide at 0.25 mg and titrate up carefully if there’s been a gap.
Learn more about tirzepatide in our dedicated Mounjaro guide and how to switch Mounjaro supplier here.
Ozempic → Wegovy (and Back): Same Molecule, Different Indication
Both are semaglutide — but:
Ozempic: licensed for type 2 diabetes, typically up to 1.0 mg (some products now 2.0 mg).
Wegovy: licensed for weight loss, titrated to a maintenance 2.4 mg.
Switching from Ozempic to Wegovy usually involves:
Moving from your current Ozempic dose to the nearest safe step in the Wegovy titration ladder.
Avoiding doubling-up in a single week.
Re-education on different pen devices, clicks, and doses.
Dive deeper in our Wegovy guide and Semaglutide guide.
Semaglutide vs Wegovy vs Ozempic — Clearing the Confusion
“Semaglutide” is the active ingredient.
“Wegovy” is the weight loss brand (higher dose, licensed for obesity).
“Ozempic” is the diabetes brand (lower doses; off‑label weight use privately).
When switching providers, make sure your medication name, strength, and indication are crystal clear to avoid dose errors.
Mounjaro (Tirzepatide) vs Semaglutide: Who Might Benefit From Switching?
Mechanism: Mounjaro targets GLP‑1 and GIP receptors; semaglutide targets GLP‑1 only.
Efficacy: Studies suggest greater average weight loss with tirzepatide — but side-effect profiles and tolerability differ per person.
Access: Local availability, brand familiarity, and cost may decide your best option.
Our clinicians can advise objectively — we stock both.
Dose Bridges & Titration Schedules When You Switch
A typical Semaglutide (Wegovy) titration:
0.25 mg → 0.5 mg → 1.0 mg → 1.7 mg → 2.4 mg (every 4 weeks)
A typical Mounjaro titration:
2.5 mg → 5 mg → 7.5 mg → 10 mg → 12.5 mg → 15 mg (every 4 weeks)
When you switch between agents, we rarely “equate” doses mathematically. Instead, we:
Look at your current tolerance
Consider side effects you’ve had
Decide where to restart to balance efficacy with minimal GI distress
Avoiding Treatment Gaps (and What If You’ve Already Missed a Dose)
Plan the switch date so your next dose lines up.
If you miss a dose: many guidelines allow taking it within 5 days, otherwise skip and resume next week — but ask us first.
If you’ve run out due to supplier issues, call us immediately. We’ll work to bridge your treatment safely.

Managing Side Effects When You Switch
Most side effects (nausea, bloating, diarrhoea, constipation) are dose and speed-of-titration related. To minimise discomfort:
Microdose (stay longer at each lower step) if you’re sensitive
Eat small, low-fat meals
Avoid fizzy drinks & large late-night meals
Hydrate well
Consider ginger, peppermint, or OTC reflux support (ask us first)
Report any signs of pancreatitis (severe upper abdominal pain) or gallbladder pain immediately.
NHS vs Private: Practical Reality
NHS access is limited (e.g., Wegovy in Tier 3/4 obesity services).
Wait lists can be long; dose optimisation slower.
Private care (like ours) offers fast access, tailored plans, and ongoing coaching.
We’ll happily support your move back to NHS services if appropriate.
Check NHS guidance:
NHS medicines for obesity & injections
Injection Technique Refreshers
Sites: abdomen (≥2 inches from navel), thigh, back of upper arm
Rotate weekly
Use new needles each time
Fridge 2–8 °C, never freeze; most pens can be at room temperature for limited days — check the leaflet
Dispose in a sharps bin (we can arrange one)
Weight Loss Plateaus After Switching
Hitting a stall? We’ll review:
Dose (are you at maintenance?)
Adherence (missed doses, wrong timing)
Lifestyle factors (sleep, stress, protein intake)
Consider switching agents, resistance training, or testing for metabolic factors (thyroid, iron, etc.)
Lifestyle, Food & Behaviour Support During Transitions
Medication is the engine, but lifestyle is the steering wheel. We’ll help you with:
Protein-first food planning
Fibre & hydration targets to combat constipation/bloating
Walking + resistance training protocols
Accountability check-ins to keep you on track
FAQs — Switching Providers & Medicines
1) Can I switch from an online provider to your clinic mid‑course?
Absolutely. Bring your last dose date, dose strength, and prescription. We’ll take it from there.
2) Do I need a “washout” period before switching from Wegovy to Mounjaro?
Usually not, but we time it dose-to-dose to minimise overlap. We’ll guide you.
3) I’m on Ozempic 1 mg — can I jump straight onto Wegovy 2.4 mg?
No. The dosages aren’t interchangeable in a straight line. We’ll re-titrate safely.
4) Are your prices really £137–£250 per month?
Yes — depending on medication & dose. That includes in-person care and local dispensing.
5) What if I’ve had bad GI side-effects and want to switch?
We can slow the titration, microdose, or switch to a better‑tolerated agent.
6) Can I switch back to the NHS later?
Yes. We can help prepare documents and ensure you transition smoothly.
7) Is it safe to stop one GLP‑1 and start another the next week?
With the right dose plan, yes. We’ll make sure the timing and dose are correct.
8) Do you offer injection training?
Yes — in-clinic. Perfect if you’re nervous about self-injecting.
9) What if my old provider won’t release my records?
We’ll work with you to reconstruct a safe dose plan from your pens, receipts & recollection.
10) Can I just keep using Ozempic off‑label for weight loss?
Privately, some do. But Wegovy is licensed for obesity at higher doses for best outcomes. We’ll discuss options.
