The semaglutide in the jab and pill mimics the actions of a hormone called GLP-1 (glucagon-like-peptide-1), which is released from the intestine after people eat.
It acts on receptors in the brain that control appetite, making people feel fuller, less hungry and crave food less.
Very common side effects with both include stomach problems, like feeling sick, being sick (vomiting), constipation and diarrhoea.
With the jab, you may get little bit of skin redness, itching or mild swelling where you inject.
Some people on the tablets or injections may experience stomach pain, headaches and tiredness.
More rarely, people can get more serious complications, like low blood sugar, pancreatitis or severe allergic reactions.
It’s worth checking the patient information leaflet for the full details.
Do not take the medication if you are under 18, pregnant or breastfeeding, and make sure you speak to your doctor about any other medical conditions you have or medication you take.
