Common adverse effects of GLP-1 receptor agonists include: Gastrointestinal symptoms (nausea, vomiting, diarrhoea, constipation) Injection site reactions Headache Fatigue Dizziness Important safety considerations include: Risk of hypoglycaemia when used with insulin or sulfonylureas (dose reduction of these agents may be needed) Potential worsening of diabetic retinopathy with semaglutide in patients with pre-existing retinopathy Risk of dehydration and acute kidney injury from persistent vomiting or diarrhoea Pancreatitis, gallbladder disease, and potential thyroid C-cell tumours (observed in rodent studies, though human relevance remains uncertain) Patients should be counselled about persistent severe abdominal pain as a potential warning sign of pancreatitis requiring immediate medical attention

Additionally, patients may prefer the weekly injection of semaglutide over the daily injections of liraglutide, as indicated by the lower discontinuation rates for weekly vs daily injections of GLP-1 receptor agonists observed in some studies [36,37,38,39]
