Semaglutide Dosage Chart For Weight Loss: A Week By Week Guide

Semaglutide is the active ingredient in Wegovy and is used to support weight loss in adults who meet specific BMI criteria. It works by reducing appetite, increasing feelings of fullness, and helping you maintain a calorie deficit more comfortably. However, successful treatment relies on following the correct dose escalation plan.

If you are considering semaglutide for weight management and would like to understand the correct dosing structure, our prescribing team can help. Reach out to us or complete our online consultation form to check your eligibility and receive personalised guidance.

Why Semaglutide Doses Increase Gradually

Semaglutide is introduced slowly to allow your body to adjust. Jumping straight to a high dose would increase the likelihood of side effects such as nausea and digestive discomfort.

Gradual titration helps:

  • Reduce the risk of side effects
  • Improve long-term tolerability
  • Allow your body to adapt safely
  • Support sustainable weight loss

This structured increase is based on clinical research and is designed to balance safety with effectiveness.

Semaglutide Weight Loss Dosage

Below is the typical schedule for semaglutide when prescribed for weight loss.

Weeks 1 To 4: 0.25 mg once weekly
This is the starter dose. It is not intended to produce significant weight loss but helps your body adapt to the medication.

Weeks 5 To 8: 0.5 mg once weekly
At this stage, appetite suppression becomes more noticeable. Side effects may still occur but often begin to settle.

Weeks 9 To 12: 1 mg once weekly
Weight loss may become more consistent. Appetite control usually improves further.

Weeks 13 To 16: 1.7 mg once weekly
This is a higher step in the escalation process. Some people remain here if they are responding well.

Week 17 Onwards: 2.4 mg once weekly
This is the typical maintenance dose for long-term weight management. Most patients who tolerate treatment move to this dose.

A new 7.2 mg semaglutide dose is expected to become available in the UK soon, offering an additional option for patients who may benefit from a higher maintenance strength under clinical supervision.

Dose Purpose Of This Dose What It Typically Achieves Key Consideration
0.25 mg Starter dose Allows the body to adjust to semaglutide Not intended for significant weight loss
0.5 mg Early treatment dose Begins noticeable appetite suppression Side effects may still be adjusting
1 mg Mid escalation dose Stronger appetite control and steadier weight loss Assess tolerability before increasing further
1.7 mg Pre maintenance step Enhanced appetite reduction for many patients Some may remain at this dose if effective
2.4 mg Standard maintenance dose Maximum clinical benefit for long term weight management Continue monitoring for tolerability
7.2 mg (coming soon) Higher maintenance option May provide additional support where clinically appropriate To be used under medical supervision

Not everyone progresses at the same pace. Your prescriber may delay increases if you are experiencing side effects or achieving good results at a lower dose.

What To Expect At Each Stage

During early weeks, common experiences include:

  • Mild nausea
  • Reduced appetite
  • Feeling full more quickly
  • Occasional bloating

As you move through the semaglutide weight loss dosage chart, appetite suppression generally becomes more consistent. Weight loss often becomes steadier once you reach higher therapeutic doses.

However, progress is not always linear. Some weeks may show little movement on the scales, which is normal. Reach out to us if you are looking for advice on how to increase your weight loss results on Wegovy.

When Dose Increases May Be Delayed

It is important not to rush dose escalation.

Your prescriber may recommend staying on a current dose longer if:

  • You are experiencing ongoing nausea or vomiting
  • You feel dizzy or fatigued
  • You are losing weight steadily without needing an increase
  • You prefer to remain on a well-tolerated dose

Increasing too quickly can reduce adherence and make side effects harder to manage.

How To Support Your Results

Semaglutide works best alongside lifestyle adjustments.

To optimise your progress:

  • Focus on protein-rich meals
  • Avoid very high-fat or fried foods
  • Stay hydrated
  • Increase daily movement
  • Track your weight weekly rather than daily

Weight loss injections are a tool, not a substitute for healthy habits.

Safety And Monitoring

Semaglutide is a prescription-only medicine in the UK. Before starting treatment, a full medical review is required to assess suitability.

Eligibility generally includes:

  • A BMI of 30 or above
  • Or a BMI of 27 or above with weight-related health conditions

It may not be suitable for individuals with certain medical histories, including specific thyroid conditions or severe gastrointestinal disorders.

Regular monitoring ensures that the semaglutide weight loss dosage chart is followed safely and adjusted appropriately for your individual needs.

Personalised Support Matters

The standard week-by-week plan is a guideline, not a rigid rule. Every patient responds differently. Some tolerate escalation smoothly, while others require a slower approach.

At The Care Pharmacy, each consultation is reviewed carefully to ensure treatment is appropriate and safely managed. If you are considering semaglutide for weight loss and want to understand the correct dosing structure for you, contact us or complete our online consultation form today to see if you are eligible and receive tailored advice.
