Semaglutide, in the jab and pill, mimics the actions of a hormone called GLP-1 (glucagon-like-peptide-1), which is released from the gut after people eat.
It acts on receptors in the brain that regulate appetite, making people feel full, feel less hungry and crave less food.
Very common side effects with both include stomach problems, such as feeling sick, nausea (vomiting), constipation, and diarrhea.
The jab may cause some redness, itching or slight swelling of the skin where you give the injection.
Some people taking the pills or injections may experience stomach pain, headache, and fatigue.
Rarely, people may have more serious complications, such as low blood sugar, pancreatitis, or severe allergic reactions.
It is advisable to check the patient information leaflet for full details.
Do not take the medication if you are under 18, pregnant, or breastfeeding, and be sure to talk to your doctor about any other medical conditions you have or medications you take.
