- Prescribe as per NICE Guideline NG28 recommendations. See also NICE Algorithm for blood glucose lowering therapy in adults with type 2 diabetes.
- To prevent waste, please avoid prescribing large quantities – GLP-1 mimetics require refrigeration and are expensive. One month’s supply should be adequate for most patients.
- Stopping rules with GLP-1 mimetics: NICE state only continue GLP‑1 mimetic therapy if the person with type 2 diabetes has had a beneficial metabolic response (a reduction of at least 11 mmol/mol [1.0%] in HbA1c and a weight loss of at least 3% of initial body weight in 6 months).
- Gastric emptying may be delayed. Therefore the rate and extent of absorption of other oral drugs administered at the same time may be affected.
- Doses of concomitant sulfonylurea may need to be reduced when a GLP-1 mimetic is started.
- Upper gastrointestinal side effects such as nausea are common with GLP-1 mimetic therapy.
- There are rare reports of acute pancreatitis in patients using these drugs. GLP-1 mimetics should be avoided in patients considered to be at high risk of pancreatitis. Patients and their carers should be told how to recognise signs and symptoms of pancreatitis.
- Thyroid adverse events, including increased blood calcitonin, goitre and thyroid neoplasm, have been rarely reported in clinical trials with liraglutide, particularly in patients with pre-existing thyroid disease.
- Diabetic ketoacidosis has been reported in patients with type 2 diabetes on a combination of a GLP-1 receptor antagonist and insulin who had doses of concomitant insulin rapidly reduced or discontinued. See MHRA for further details.
