GCG and Hypoglycemia: Drugs such as biguanides (e.g. metformin), thiazolidinediones (e.g. rosiglitazone), alpha-glucosidase inhibitors (e.g. acarbose), sodium-glucose transporter-2 (SGLT) inhibitors (e.g. dapagliflozin, empagliflozin) and glucagon-like peptide 1 (GLP-1) agonists (e.g. exenatide) are thought to have a minimal effect on increasing the risk of exercise-induced hypoglycaemia when used alone.
