Factual patient information
Weight management treatment information
Understand the prescription treatment formulations that may be considered following clinical assessment, how they differ and what affects treatment choice.
This page provides general information and does not recommend one medicine or formulation over another.
Treatment follows assessment, not online selection
Prescription treatment is only considered after a qualified prescriber has reviewed your medical history, current medicines, relevant risks and individual circumstances. A requested treatment will not be prescribed if it is unsuitable or if another approach is considered safer or more appropriate.

Individual clinical decisions
What affects treatment choice?
The most suitable plan is not determined by price or personal preference alone. Your prescriber considers the whole clinical picture.
Health history
Existing conditions, previous diagnoses, symptoms and relevant family or surgical history.
Current medicines
Potential interactions and medicines that may require dose adjustment, timing advice or monitoring.
Previous treatment
What you have used, your last dose, response, side effects and why treatment changed or stopped.
Tolerability
Your ability to manage side effects, remain hydrated and maintain an appropriate eating pattern.
Practical routine
Whether you can safely follow a weekly injection or the daily tablet fasting instructions.
Ongoing care
Your capacity to attend reviews, engage with lifestyle support and continue treatment safely.
The clinical pathway
How a treatment decision is reached
The choice is made with you after assessment. Sometimes the safest decision is not to prescribe a medicine.

Choosing and researching treatment
Use the medicine-specific pages for fuller dosing and safety information.
Contact TheraVita →Can I select a medicine from this page?
No. This is an information page, not a medicine-selection tool. Treatment is only considered following individual clinical assessment and prescribing remains at the prescriber’s professional discretion.
Is the cheapest formulation automatically the most suitable?
No. Cost can be discussed, but safety, suitability, medicines, health history, practical administration and ongoing monitoring all affect the decision.
Are injection and tablet doses equivalent?
No. Different medicines and formulations have their own dose schedules and absorption. Do not convert a dose or switch treatments without prescriber guidance.
What if I am already receiving treatment elsewhere?
Your new prescriber will need information such as the medicine, strength, last dose, treatment duration, progress, side effects and evidence of previous prescribing. Do not overlap supplies from different providers.
Could the assessment result in no medicine being prescribed?
Yes. Prescription treatment may be unsuitable, further information may be needed, or another approach may be safer. The assessment does not guarantee a prescription.
