Ozempic® 0.25 mg Weight Management Pen — Basic Pre-injection Health Check Included
What is Ozempic®?
Ozempic® is a prescription medicine developed by Novo Nordisk. It contains the active ingredient semaglutide, which belongs to a class of medicines known as GLP-1 receptor agonists.
Ozempic® supports blood glucose control by helping improve insulin response, stabilise blood sugar levels and support overall metabolic health. It is administered using a pre-filled injection pen and is usually injected once weekly.
Ozempic® has been approved by the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) since 2017, and is used in many regions, including Hong Kong.
A basic pre-injection health check is required, including:
- Liver function test
- Kidney function test
- Fasting blood glucose
- HbA1c
- Urinalysis
- Basic physical examination
This programme must be used under the guidance of qualified healthcare professionals and prescribed by a doctor.
If required, a nurse may assist with the first injection.
A one-to-one registered dietitian consultation service is also available to support your weight management plan.*
Ozempic® may be considered for adults who:
- Have a BMI of 30 kg/m² or above
- Have a BMI of 27 kg/m² to below 30 kg/m², with relevant health or metabolic concerns
- Find it difficult to maintain a regular exercise routine due to a busy lifestyle
- Frequently experience a large appetite, snack cravings or late-night eating habits
Suitability must be assessed by a doctor based on your medical history, current health condition and treatment needs.
Ozempic® may not be suitable for individuals who:
- Have previously had an allergic reaction to semaglutide or other GLP-1 receptor agonists
- Have severe gastrointestinal disease
- Are pregnant or breastfeeding
- Have a history of severe acute pancreatitis
- Have severe liver or kidney impairment or failure
- Have medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)
A doctor’s assessment is required before starting treatment.
Ozempic® is usually injected once weekly. It is advisable to inject it on the same day each week to maintain a regular schedule.
Ozempic® is administered by subcutaneous injection. The recommended injection areas are the front of the abdomen, the outer thigh or the upper arm.
- Prepare the injection pen
Take out the injection pen and check that the solution is clear and free from visible particles. Attach a new needle. - Set the dose
Turn the dose selector to the dose instructed by your doctor. - Clean the injection site
Clean the injection area with an alcohol swab. - Inject the medication
Insert the needle vertically into the skin and press the injection button until the indicator shows that the injection is complete. - Hold for a few seconds
Keep the needle under the skin for approximately 6 seconds after injection to help ensure the dose has been fully delivered. - Dispose of the needle safely
Remove the used needle immediately after use and dispose of it properly in a sharps container.
Ozempic® dosing is not usually started at the full treatment dose. It is gradually adjusted according to the patient’s tolerance and treatment response. This gradual approach may help reduce gastrointestinal side effects and improve tolerability.
Doctors commonly start with 0.25 mg once weekly for 4 weeks. This starting dose is mainly intended to help the body adapt to the medicine. After the first 4 weeks, the dose may be increased to 0.5 mg once weekly, where clinically appropriate.
If, after medical review, the treatment response is not yet sufficient and the patient is tolerating the medicine well, the doctor may consider increasing the dose to 1.0 mg once weekly, or further adjustment where appropriate.
Your doctor will assess your blood glucose level, weight changes, overall health condition and response to the medicine before adjusting the dose.
- Prepare the injection pen
Ozempic® is a prescription medicine and may cause the following common side effects, which are usually mild and more likely to occur during the initial adjustment period:
- Nausea or vomiting
- Diarrhoea or constipation
- Dizziness or tiredness
- Reduced appetite
- Mild redness or swelling at the injection site
These symptoms commonly occur at the beginning of treatment. As the body adjusts to the medication, they may gradually improve for many users.
Less common but more serious side effects may involve gallbladder disease or pancreatitis. Close monitoring during treatment is therefore important, and medical advice should be sought promptly where needed.
If you experience any side effects, especially if the symptoms are severe or persistent, please speak to your doctor.
How to Store Ozempic®
Before Opening
- Store at 2°C to 8°C in a refrigerator
- Do not freeze
- Do not place in the freezer
- Avoid placing the pen near the cooling element or ice compartment to prevent freezing
After Opening / During Use
- The pen may be stored at room temperature, not above 30°C, or in a refrigerator
- Keep away from direct sunlight and high temperatures
- Replace the pen cap after use to help prevent contamination
Do not use the injection solution if it becomes discoloured, cloudy or contains visible particles or sediment.
During treatment, blood pressure, blood glucose and cholesterol levels may need to be monitored, particularly for patients with metabolic conditions or chronic illnesses.
As body weight or blood glucose levels change, the dosage of existing medicines may need to be reviewed and adjusted by a doctor where clinically appropriate.
The use of other weight management medicines at the same time is generally not recommended unless advised by a doctor, as this may affect treatment response or increase the risk of side effects.
Ozempic® is a personalised prescription medicine. It should not be shared with others. You should not adjust the dosage or stop treatment by yourself. Please follow your doctor’s instructions and attend regular follow-up appointments.
