More about what Ozempic is used for
Ozempic is the brand name for semaglutide, a GLP-1 receptor agonist given as a weekly injection under the skin. In the UK it is prescribed for adults with type 2 diabetes when your clinician decides it is appropriate, often alongside diet, exercise, and other glucose-lowering medicines.
It is a prescription-only medicine. Different brands and strengths exist for different licensed uses; always use the product and dose prescribed for you.
How does Ozempic work, and how long does it take to work?
GLP-1 medicines increase insulin release when blood glucose is high, slow stomach emptying, and can reduce appetite, which together improve glucose control for many people with type 2 diabetes.
It is not insulin and is not a replacement for emergency diabetes care or for type 1 diabetes.
How and when should you take Ozempic?
Your nurse, pharmacist, or prescriber will show you how to inject once weekly on the same day each week, rotating injection sites as advised. Follow the device instructions for your pen.
Start doses are often low and increased gradually to limit nausea — do not change the schedule without medical advice.
What are the common side effects of Ozempic?
Very common effects include nausea, vomiting, diarrhoea, constipation, and abdominal discomfort, especially when starting or increasing dose. These often improve over time.
Speak to your GP or diabetes team if symptoms are severe or persistent — they may adjust timing or dose.
Serious side effects of Ozempic — when to get urgent help
Seek urgent help for severe allergic reaction, severe abdominal pain with vomiting (possible pancreatitis), or symptoms of low blood sugar if you also take insulin or sulfonylureas.
Your prescriber will discuss rare risks such as thyroid tumours in people with certain family histories — follow the product safety information you are given.
What if you miss a dose of Ozempic?
If you miss a dose, follow the missed-dose instructions in your leaflet or ask your pharmacist — timing rules depend on how late you are.
Do not take two doses together to catch up unless your prescriber tells you to.
Who should not take Ozempic?
Ozempic is not suitable for everyone — for example pregnancy, breastfeeding (unless specialist advice says otherwise), some pancreatic or thyroid conditions, and personal or family history relevant to the medicine’s warnings.
Always give your full medical history before starting; do not share pens or buy prescription medicines from unregulated sources.
Can you take paracetamol or ibuprofen with Ozempic? — other interactions
Other diabetes medicines, especially insulin and sulfonylureas, can increase hypo risk when combined — your prescriber may reduce those doses.
Some oral medicines may absorb differently because stomach emptying slows — your pharmacist can advise spacing.
Ozempic in pregnancy and breastfeeding
Do not use in pregnancy; use reliable contraception if you could become pregnant and discuss planning with your GP.
Blood tests and monitoring on Ozempic
HbA1c, weight, blood pressure, kidney function, and symptom reviews are usually part of follow-up. Attend diabetes clinic appointments.
What might your GP prescribe instead of Ozempic?
Your diabetes team may consider other GLP-1 receptor agonists, Metformin, SGLT2 inhibitors, insulin, or other classes depending on your glucose, weight, heart, and kidney needs.
