Weight-loss injections such as Mounjaro, Wegovy, and Saxenda belong to a class of medications known as GLP-1 receptor agonists. They work by slowing stomach emptying and regulating appetite hormones, helping you feel full sooner and stay satisfied for longer.

These treatments are designed to support clinically significant weight loss when used in conjunction with a healthy diet and regular exercise. For best results, our doctors create a personalised plan that includes nutrition, activity, and ongoing medical supervision.

This is a medical weight management service designed for adults who are clinically overweight or obese. It is not suitable for cosmetic or minor weight loss.

To qualify for treatment, you must meet one of the following criteria:

 

  • BMI ≥27 with weight-related medical conditions (such as high blood pressure or high cholesterol), or

  • BMI ≥30, classed as obese.

 

Please note: we do not currently prescribe GLP-1 medications for patients with type 2 diabetes. If you are being treated for diabetes, this service will not be appropriate for you.

 

If your goal is to lose a small amount of weight, this programme is not suitable.

How Weight Loss Injections Work?

Weight loss injections such as Wegovy, Mounjaro, and Saxenda belong to a class of medications known as GLP-1 receptor agonists (and in the case of Mounjaro, a dual GLP-1/GIP agonist).

Reduce appetite

By slowing stomach emptying and signalling satiety to the brain, they make it easier to eat smaller portions and stay satisfied.

Regulate blood sugar levels

They stabilise glucose levels and reduce energy dips, which helps prevent cravings and overeating.

Sustainable weight loss

In clinical trials, patients lost up to 15–22% of body weight when used alongside healthy eating and regular activity.

Weightloss Treatments We Offer

We currently offer prescriptions for the most effective, evidence-based medications:

Wegovy

Wegovy (semaglutide) is a once-weekly GLP-1 receptor agonist designed to support medically supervised weight loss. It works by mimicking a natural hormone that helps regulate appetite and food intake, slowing digestion and prolonging the feeling of fullness.

In clinical studies, patients lost an average of 15% of their body weight over time when combined with a balanced diet and regular physical activity. Wegovy is suitable for adults with BMI ≥30, or BMI ≥27 with weight-related health concerns such as high blood pressure or cholesterol.

Mounjaro (tirzepatide) is the first dual GLP-1 and GIP receptor agonist, making it one of the most advanced and effective weight loss treatments available. By targeting two key hormones that regulate appetite and metabolism, Mounjaro helps reduce hunger, increase fullness, and improve blood sugar control.

 

Clinical trials have shown that patients using Mounjaro achieved a body weight reduction of up to 22.5%, making it the most potent injectable weight loss medication to date. It is taken once weekly via injection.

Saxenda (liraglutide) is a daily GLP-1 injection that has been prescribed for weight management for over a decade. It works by regulating appetite and slowing stomach emptying, helping patients eat less and feel fuller for longer.

Clinical research indicates that Saxenda users can expect to lose 5–10% of their body weight when used in conjunction with lifestyle changes. It’s a trusted choice for patients seeking gradual, medically guided weight loss under the supervision of a doctor.

Frequently Asked Questions

Most prescription weight-loss injections available in Ireland, including Wegovy, Mounjaro, and Saxenda,  belong to a class of medications called GLP-1 receptor agonists.
These medicines mimic a natural hormone that helps regulate appetite, blood sugar, and digestion.

They work in three main ways:

  1. Reduce appetite: you feel full sooner and eat smaller portions.
  2. Slow digestion: food stays in your stomach longer, which helps control cravings.
  3. Stabilise blood sugar: prevents energy dips that trigger hunger.

Combined with healthy eating and exercise, GLP-1 injections can help you achieve clinically significant, sustainable weight loss.

While all three are GLP-1–based treatments, they differ slightly in dosing, duration, and mechanism:

  • Wegovy (semaglutide): Once-weekly injection. Mimics GLP-1 hormone to regulate appetite and calorie intake. Proven in clinical trials to reduce body weight by 10–15% on average over 68 weeks.
  • Mounjaro (tirzepatide): Once-weekly injection that acts on two hormones (GLP-1 and GIP), enhancing appetite control and insulin sensitivity. Early studies show 15–20% average weight reduction.

Saxenda (liraglutide): Once-daily injection. The first GLP-1 medication licensed for weight management in Ireland. Typically results in 5–10% weight loss when used with diet and exercise.

Results vary by individual, but clinical trials show that when combined with healthy habits:

  • Wegovy users lose around 15% of their starting weight over 12–15 months.
  • Mounjaro users may achieve up to 20% reduction in body weight.
  • Saxenda users typically lose 5–10% within the first year.

Sustained results depend on consistent use, lifestyle changes, and ongoing medical supervision.

Yes, when prescribed by a registered doctor and used correctly, GLP-1 medications are considered safe and clinically effective. They are licensed by the HPRA (Health Products Regulatory Authority) in Ireland and the EMA (European Medicines Agency).

Common side effects include mild nausea, indigestion, or constipation during the first few weeks as your body adjusts. These symptoms usually ease as the dose is increased gradually.
Serious side effects are rare but may include allergic reactions or pancreatitis; your smartscripts.ie doctor will review your full medical history before prescribing to ensure suitability.
