1. What Ozempic® is and what it is used for

Ozempic® contains the active substance semaglutide. It helps your body reduce your blood sugar level only when blood sugar is too high and can help prevent heart disease in patients with type 2 diabetes mellitus (T2DM). It also helps to slow down deterioration of kidney function in patients with T2DM by a mechanism beyond blood glucose lowering.

Ozempic® is used to treat adults (aged 18 years and older) with type 2 diabetes when diet and exercise is not enough:

Warnings and precautions

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

This medicine is not the same as insulin and you should not use it if:

•

does not produce any insulin

you have type 1 diabetes – a condition where your body

•

diabetes with high blood sugar, breathing difficulty, confusion, excessive thirst, a sweet smell to the breath or a sweet or metallic taste in the mouth.

you develop diabetic ketoacidosis – a complication of

Ozempic® is not an insulin and should therefore not be used as a substitute for insulin.

If you know that you are due to have surgery where you will be under anaesthesia (sleeping), please tell your doctor that you are taking Ozempic®.

Stomach and gut problems and dehydration

During treatment with this medicine, you may feel sick (nausea) or be sick (vomiting), or have diarrhoea. These side effects can cause dehydration (loss of fluids). It is important that you drink plenty of fluids to prevent dehydration. This is especially important if you have kidney problems. Talk to your doctor if you have any questions or concerns.

Severe and on-going stomach pain which could be due to acute pancreatitis

If you have ever had pancreatitis (inflammation of the pancreas) which may cause severe pain in the stomach and back which does not go away; see section 4.

Low blood sugar (hypoglycaemia)

Combining a sulfonylurea or an insulin with this medicine might increase the risk of getting low blood sugar levels (hypoglycaemia). Please see section 4 for the warning signs of low blood sugar levels. Your doctor may ask you to test your blood sugar levels. This will help your doctor decide if the dose of the sulfonylurea 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 are using insulin, this medicine may lead to a worsening of your vision, and this may require treatment. Tell your doctor if you have diabetic eye disease or if you experience eye problems during treatment with this medicine. In case you have potentially unstable diabetic eye disease, it is not recommended that you use Ozempic® 2

mg.

Sudden changes to your eyesight

If you notice a sudden loss of vision or rapidly worsening eyesight during treatment with semaglutide, urgently contact your doctor. This may be caused by a very rare side effect called non-arteritic anterior ischaemic optic neuropathy (NAION) (See section 4: Serious side effects). Your doctor will refer you for an eye examination by an ophthalmologist and you may have to stop treatment with semaglutide.

Patients with delayed stomach emptying (gastroparesis)

If you have slow (delayed) stomach emptying (called gastroparesis), use of Ozempic® may lead to serious or severe gastrointestinal adverse events. Talk to your doctor before using Ozempic®.

Children and adolescents

This medicine is not recommended in children and adolescents aged under 18

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 bought without a prescription.

In particular, tell your doctor, pharmacist or nurse if you are using medicines containing any of the following:

•

reduce blood clotting (oral anti-coagulants). You may need frequent blood tests to check how quickly your blood clots.

Warfarin or other similar medicines taken by mouth to

•

reduce the dose of insulin and will recommend you to monitor your blood sugar more frequently, in order to avoid hyperglycaemia (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).

If you are using insulin, your doctor will tell you how to

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you might be pregnant, or are planning to have a baby, ask your doctor for advice before taking this medicine.

This medicine should not be used during pregnancy, as it is not known if it affects an unborn baby. Therefore, use of contraception is recommended while using this medicine. If you wish to become pregnant, discuss how to change your treatment with your doctor as you should stop using this medicine at least 2 months in advance. If you become pregnant while using this medicine, talk to your doctor right away, as your treatment will need to be changed.

Do not use this medicine if you are breast-feeding, as it is unknown if it passes into breast milk.

Driving and using machines

Ozempic® is unlikely to affect your ability to drive and use machines. If you use this medicine in combination with a sulfonylurea or insulin, low blood sugar (hypoglycaemia) may occur which may reduce your ability to concentrate. Do not drive or use machines if you get any signs of low blood sugar. See section 2, ‘Warnings and precautions’ for information on increased risk of low blood sugar and section 4 for the warning signs of low blood sugar. Talk to your doctor for further information.
