If you're struggling with overweight issues or obesity and are on the hunt for an effective weight loss management solution, you may have heard of Wegovy.

This article aims to provide a comprehensive guide on how Wegovy works in treating overweight and obesity conditions. Wegovy, available as a pen or injection, is garnering attention for its potential to aid in weight loss. But how does it work? What's the correct dosage? How long should you use it? These are some of the pertinent questions we will explore.

Dosage Guidelines

The dosage for Wegovy is carefully planned to ensure optimal efficacy and minimal side effects. The initial dosage starts at 0.25 mg for the first four weeks, and gradually increases until it reaches a maintenance dose of 2.4 mg from week 17 onwards.

Starting Dose

The initial dose for Wegovy is usually 0.25 mg once a week. This helps your body adapt to the medication.

Dose Titration

Dose Titration is the process of adjusting the dose of a medication for optimal efficacy and minimal side effects. Health care providers usually adjust the dose in stages.

Maintenance Dose

The maintenance dose can be up to 2.4 mg per week, depending on advice from your health care provider.

How to Use Wegovy?: A Step-by-Step Guide

Proper administration of Wegovy is essential for optimal results. Follow these steps to ensure you're using the medicine correctly.

  • Preparation: Start by washing your hands thoroughly with soap and water. Clean the injection site using an alcohol swab.
  • Remove the Cap: Take the Wegovy pen and carefully remove the protective cap, revealing the rubber stopper.
  • Attach the Needle: Remove the protective covering from the needle. Attach the needle to the pen by twisting it clockwise until it is securely in place.
  • Prime the Pen: To ensure accurate dosing and to remove any air bubbles, prime the pen. Press the dose button until a small drop of medication appears at the tip of the needle.
  • Select the Injection Site: Choose your injection site—either the abdomen, thigh, or upper arm. Make sure to rotate the injection sites to avoid tissue damage.
  • Inject the Dose: With a quick, dart-like motion, insert the needle into the skin at a 90-degree angle. Press the dose button to administer the medication.
  • Confirmation: Confirm that the full dose has been injected by checking the dose counter on the pen.
  • Withdraw the Needle: After injecting, pull the needle out gently at the same angle you inserted it.
  • Dispose of the Needle Safely: Place the used needle in a sharps container for proper disposal. Do not dispose of it in household waste.
  • Store the Pen: Replace the protective cap and store the pen as directed in the accompanying medication guide.

If you experience any complications or have concerns about the medicine, consult your health care provider for advice.

Administration Guidelines

Wegovy is administered as a subcutaneous injection. The best places for the injection are the upper arms, stomach, or upper legs.

Other Considerations

What Should I Do If I Cannot Tolerate the New Dose?

What Should I Do If I Miss a Dose?

What If I Want to Change the Day I Take Wegovy?

Consult your health care provider before making changes to your dosing schedule.

Mechanism of Action

Wegovy works by mimicking a hormone in the body that regulates appetite. It binds to receptors in the brain that control hunger, making you feel fuller for longer. This helps to reduce calorie intake and, consequently, aids in weight loss.

Side Effects and Contraindications

Like any medication, Wegovy comes with its own set of side effects, which may include nausea, vomiting, and diarrhoea. It is contraindicated in certain conditions, such as thyroid cancer and multiple endocrine neoplasia syndrome type 2. Always consult your health care provider for a full list of side effects and contraindications.


Wegovy offers a promising avenue for weight loss and obesity management, but it is crucial to adhere to recommended guidelines and best practices. For personalised treatment plans, always consult your health care provider.
