For your safety, we cannot prescribe or supply a higher dose of weight-loss medication unless you can provide evidence of a previous prescription for that dose (or confirmation that you have safely completed the lower dose). If you are new to treatment, you will need to start at the recommended starting dose. Dose increases are only considered after a clinical review to ensure the medication has been well tolerated. This policy follows national safe prescribing standards and is in place to protect your health and wellbeing.
