Ozempic – Semaglutide uses, dose and side effects


0.25 mg solution for injection in pre-filled pen semaglutide

What Ozempic is and what it is used for

Ozempic contains the active substance semaglutide. It helps the body lower your blood sugar, but only when your blood sugar is too high. It can also help prevent heart disease.

Ozempic is used:

  • as the only medicine – unless diet and exercise alone are enough to get your blood sugar under control, and you can not use metformin (another diabetes medicine) or
  • together with other diabetes medicines – when these are not enough to get your blood sugar under control. These other medicines can be diabetes medicines that you swallow (such as metformin, a thiazolidinedione, sulphonylurea, sodium-glucose transporter 2 (SGLT2) inhibitors) or insulin.

You must continue to follow the advice on diet and exercise given to you by your doctor, pharmacist, or nurse.

What you need to know before you use Ozempic

Do not use Ozempic

  • if you are allergic to liraglutide or any of the other ingredients of this medicine (listed in section 6).

Warnings and cautions

Talk to your doctor, pharmacist, or nurse before using this medicine.

This medicine is not insulin and should not be used if:

  • you have type 1 diabetes – a condition in which the body does not produce any insulin
  • you develop diabetic ketoacidosis – a complication of diabetes with high blood sugar, difficulty breathing, confusion, excessive thirst, sweet breath, or a sweet or metallic taste in the mouth.

Ozempic is not insulin and should therefore not be used as a replacement for insulin.

Effects on the digestive system

During treatment with this medicine, you may feel unwell, vomit, or have diarrhea. These side effects can cause dehydration (fluid loss). It is important to drink plenty of fluids to prevent dehydration. This is especially important if you have kidney problems. Talk to a doctor if you have any questions or concerns.

Severe and persistent abdominal pain that may be due to acute inflammation of the pancreas

If you have severe and persistent stomach pain – see a doctor immediately as this may be a sign of acute pancreatitis ( inflammation of the pancreas).

See section 4 for warning signs of the inflamed pancreas.


Combining sulphonylurea or insulin with this medicine may increase the risk of low blood sugar (hypoglycemia). See section 4 for information on warning signs of low blood sugar. Your doctor may ask you to test your blood sugar levels. This will help your doctor decide if a dose of sulphonylurea or insulin needs to be changed to reduce the risk of low blood sugar.

Diabetic eye disease ( retinopathy )

If you have diabetic eye disease and use insulin, this medicine may lead to your vision deteriorating, which may require treatment. Tell your doctor if you have diabetic eye disease or if you experience eye problems during treatment with this medicineIf you have a diabetic eye disease that may be unstable, we do not recommend that you take Ozempic 2 mg.

Children and young people

Other medicines and Ozempic

Tell your doctor, pharmacist, or nurse if you are taking, have recently taken, or might take any other medicines, including herbal medicines or other medicines you have bought without a prescription.

Especially if you are taking medicines that contain any of the following, tell your doctor, pharmacist, or nurse:

  • Warfarin or similar medicines are taken orally to reduce blood clotting capacity (oral anticoagulants ). You may be required to have frequent check-ups of your blood clotting capacity.
  • If you are taking insulin, your doctor will tell you how to lower your insulin dose and recommend that you measure your blood sugar more often to avoid hyperglycemia (high blood sugar) and diabetic ketoacidosis (a complication of diabetes that occurs when the body is unable to break down glucose because there is not enough insulin ).

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor for advice before using this medicine.

This medicine should not be used during pregnancy as it is not known if it may affect your fetus. Therefore, you should use a contraceptive when using this medicine. If you want to get pregnant, stop using this medicine at least two months in advance. If you become pregnant while taking this medicine, talk to your doctor immediately as your treatment may need to be changed.

Do not use this medicine if you are breastfeeding, as it is not known if it passes into breast milk.

Driving and using machines

Ozempic is unlikely to affect your ability to drive or use machines. If you use this medicine together with a sulphonylurea or insulin, low blood sugar (hypoglycemia) may occur which may lower your ability to concentrate. Avoid driving or using machines if you get signs of low blood sugar. Section 2, “Warnings and precautions” provides information on the increased risk of low blood sugar and Section 4 provides information on the warning signs for low blood sugar. For more information, talk to your doctor.
