Frequently asked questions

What are injectable weight loss medications?

These are revolutionary injectable treatments proven to help you lose weight. They stimulate hormonal receptors related to energy and appetite, and can help you achieve your weight loss goals when combined with dietary and lifestyle changes

How do weight loss injectables work?

Depending on the treatment you use, they stimulate two different naturally occurring hormonal receptors: glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP).

GLP-1 helps to regulate blood sugar levels, which in turn talks to the brain to make you feel less hungry and prevent cravings. It also slows down the emptying of the stomach to keep you feeling fuller for longer.

GIP regulates energy balance in brain and fat cells, enhancing the GLP-1 effect of suppressing your appetite and improving sugar control.

What do weight loss injections contain?

The active ingredient in Wegovy is Semaglutide. Semaglutide belongs to a class of GLP-1 medications which contributes to reducing hunger pangs, slowing gastric emptying, and increasing insulin production. The active ingredient in Mounjaro is Tirzepatide. This has a similar effect; decreasing food intake and slowing gastric emptying.

How much weight can you lose?

If your treatment is followed correctly and you adopt lifestyle changes (healthier eating and exercise) you can lose up to 15% to 20% of your bodyweight in a 17-month period. Results are dependent on the treatment you choose, as clinical studies show varying results per treatment type.

Will I be eligible for weight loss treatment?

To ensure safe supply, we ask patients to meet our eligibility requirements for injectable weight loss medications. Our eligibility are as follows:

Between 18 and 85
You have a BMI above 30 or have a BMI above 27 and a weight-related accompanying condition (e.g. high blood pressure or cholesterol amongst others)
Meet all other clinical criteria subject to your medical history

What are the common side effects of weight loss injections?

It is common to experience side effects as you increase your dosage over time. Common side effects of these medications include nausea, headaches, diarrhoea and vomiting. We would expect these to subside in a few weeks into your treatment plan.

Is it safe?

These weight loss medications are approved for use by the MHRA, the UK government department responsible for ensuring that medicines and medical devices work and are safe.

Your treatment will be supervised by our qualified pharmacists and clinical team at all times. If you experience any side effects or changes in overall health, you must let us know so we can ensure your safe health & wellbeing.

How much are weight loss injection pens?

Treatment prices will start from around £79 per month; including your medication, at-home delivery and the supportive oversight of our clinical team. As your treatment progresses and your monthly dosage increases, the monthly price may also increase.

How do I re-order my next dose?

Phlo's clinical team will check in regularly with you via email to see how you are progressing with treatment. Towards the end of your first month, you will receive reminder emails with instructions on how to re-order your next dose. You will be directed to a shorter clinical consultation designed to assess how you are getting on with your treatment and whether or not you need a dosage adjustment. You can also log in to your H&B Weight Loss Service account and re-order this way should you choose. For optimal results, we encourage patients to take a long term view of this treatment on a monthly basis until you reach your weight loss goal.

How do I dispose of my sharps bin?

We advise patients to contact their local council as the first option as they can usually arrange collection from your home address or provide guidance on local drop off points. Some pharmacies will also accept sharps bins for disposal but this will be at the discretion of the particular pharmacy.
