As with all medication, Saxenda can be associated with unwanted side effects. Although usually mild, some can be more severe, which may result in your treatment being stopped. You should always read the patient information leaflet fully before you begin treatment.
When you first start your treatment, you may experience some stomach upset, such as vomiting or diarrhoea, and may also lose some bodily fluids. Therefore, it is important to drink plenty of fluids to keep yourself hydrated. Most mild side effects will settle once your body gets used to the new medication. However, if any side effect persists, stop the treatment and talk to a doctor.
Sometimes side effects of Saxenda can be very serious, such as severe allergic reactions. If you get any symptoms, such as problems breathing, swelling of your face or throat, or a fast heartbeat, you must get medical help immediately.
Rarely there have been cases reported of inflammation of the pancreas (pancreatitis). Pancreatitis is a serious, potentially life-threatening, medical condition. If you experience any of the following side effects stop taking Saxenda immediately and get medical help: severe and persistent pain in the abdomen (stomach area) which might reach through to your back with nausea or vomiting.
