Private weight loss clinic in Cardiff
Wellness Pharmacy in Old St Mellons runs a pharmacist-led weight loss clinic, in store or by video call. We start with a free consultation to check whether prescription weight loss treatment is safe and suitable for you.
If treatment is appropriate, we explain your options, supply your first month and see you every month to review your progress. Booking a consultation does not guarantee that treatment will be prescribed.

Local clinical support, not just an online form
Many online services rely on a questionnaire. At Wellness Pharmacy you speak to a pharmacist prescriber who checks your measurements, medical history and current medicines, and talks through what is realistic for you.
You can attend in person at our Old St Mellons pharmacy or have your consultations by video call, and you will see the same local team throughout your treatment.

How prescription weight loss treatment works
The weight loss medicines we prescribe mimic natural gut hormones (GLP-1, and in some cases GIP) that help you feel full sooner and reduce appetite. Most people eat less as a result, which helps them lose weight when combined with diet and activity changes.
Reduced appetite
Many people notice a reduced appetite within the first few weeks of treatment.
Gradual dose increases
Doses are increased step by step to help your body adjust and reduce side effects.
Lifestyle support
Treatment works best alongside changes to diet and physical activity, which we support at each review.
Treatment options and prices at our Cardiff weight loss clinic
Your pharmacist will recommend the most suitable option after your consultation. Prices are for a one-month supply and depend on the strength prescribed.

Prices can change with wholesaler costs and availability, and were correct as of March 2026. Treatment is only supplied after a consultation confirms it is clinically suitable.
Important safety information
Weight loss medicines are not suitable for everyone. Tell us if you are pregnant, planning a pregnancy or breastfeeding, or have a history of pancreatitis, certain thyroid cancers, gallbladder problems or an eating disorder. Seek urgent medical help if you develop:
- Severe, persistent stomach pain that may spread to your back
- Signs of an allergic reaction, such as swelling of the face or difficulty breathing
- Severe or ongoing vomiting or diarrhoea with signs of dehydration
Common side effects include nausea, constipation, diarrhoea and indigestion, which often settle as your body adjusts. Use NHS 111 Wales for urgent advice, or call 999 in an emergency.
Treatment works alongside lifestyle change
Medicines help with appetite, but lasting results come from changes to what and how much you eat, and how active you are.
At each monthly review we check your weight and BMI, how you are getting on with treatment, and give practical advice on diet and activity.
Transferring from another provider
If you are already on treatment from another provider, we can review your history and current dose and, where appropriate, continue your care locally.
Please bring details of your current treatment and dose to your consultation.
