Wegovy® is a GLP-1 receptor agonist, which means it works by mimicking the effects of a natural hormone called glucagon-like peptide-1 (GLP-1). GLP-1 is released after eating and helps to control appetite, regulate blood sugar levels, and promote significant weight loss. Wegovy® is also approved to lower the risk of major cardiovascular events such as death, heart attack, or stoke, in adults with known heart disease and with either obesity or overweight.

When to Use Wegovy?
Wegovy is a prescription that supports weight loss. As a GLP-1 receptor, it's suitable for adults and some adolescents struggling to lose weight through exercise and diet alone.
If any of the following apply, Wegovy can be a beneficial treatment:
- Your BMI is Over 30: People with a BMI of 30 or over can use Wegovy. If you have a BMI of 27 and a weight-related comorbidity, you may also be eligible for the medication.
- Ethnic Groups: In some cases, individuals in ethnic groups including Africa, African-Caribbean, South Asian, Asian, and Middle Eastern may be able to use Wegovy with a lower BMI due to the higher risk of obesity-related illnesses.
Wegovy Age Restrictions
In most cases, Wegovy is suitable for adults between 18 and 75, as long as they meet the other eligibility criteria. However, adolescents with a high BMI who have tried other weight loss treatments may be eligible for Wegovy weight loss injection treatments if a medical professional feels it's beneficial.
How to Use Wegovy?
Wegovy is a once-weekly injection, making it a popular alternative to many other weight-loss drugs. If you're using it for the first time, it's essential to check the flow by turning the dosage indicator until it shows the flow check symbol, then holding it away from you while you press the button.
If no drops appear, you may need to use a new pen or change the needle if possible. Most people choose the thigh, abdomen, or upper arm as an injection site - alternating between each.
Wegovy Dosage
Wegovy is available in a pre-filled pen containing 0.25 mg, 0.5 mg, 1 mg, 1.7 mg, 2.4 mg or 7.2mg (3x 2.4mg pens) of semaglutide.
Users should follow the dose escalation schedule under the supervision of medical professionals. The dosage is gradually increased over the first 16 weeks of treatment. The starting dose is 0.25 mg once weekly and increases to 7.2 mg once weekly.
Our specialists at Pharmacy Online can offer advice and discuss whether you can increase the dosage or should wait.
