Summary
Phenothiazines can affect glucose metabolism and may cause hyperglycemia, opposing the glucose-lowering effect of liraglutide. Glycemic control may therefore be less predictable in patients receiving both drugs.
What this interaction means in plain words
Fluphenazine and Liraglutide have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Fluphenazine belongs to Central Nervous System; Liraglutide belongs to Endocrine.
Why it happens
Antipsychotic-associated impairment of glucose tolerance opposes GLP-1 receptor agonist glucose lowering; the mechanism is not well defined.
What to do
Monitor blood glucose and HbA1c when fluphenazine is started or its dose is changed, and adjust diabetes therapy as needed.

- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
