Summary
Clozapine is strongly associated with weight gain, insulin resistance, hyperglycemia and sometimes diabetic ketoacidosis. This can substantially undermine glycemic control with insulin degludec-liraglutide.
What this interaction means in plain words
Clozapine and Insulin degludec-liraglutide can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Clozapine belongs to Central Nervous System; Insulin degludec-liraglutide belongs to Endocrine.
Why it happens
Clozapine induces insulin resistance and may impair pancreatic insulin secretion and promote weight gain, opposing antidiabetic therapy.
What to do
Monitor blood glucose frequently, particularly when clozapine is started or titrated, and increase antidiabetic therapy as needed. Reassess the regimen if hyperglycemia persists.
