Summary
Dulaglutide slows gastric emptying and may modestly alter absorption of oral drugs. Lithium has a narrow therapeutic range, but a clinically important change has not been well documented. Gastrointestinal adverse effects or dehydration from dulaglutide could secondarily raise lithium levels.
What this interaction means in plain words
Dulaglutide and Lithium have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Dulaglutide belongs to Endocrine; Lithium belongs to Central Nervous System.
Why it happens
Delayed gastric emptying may alter lithium absorption rate, and GLP-1 related volume loss may reduce lithium clearance.
What to do
Check serum lithium after starting or escalating dulaglutide, especially if vomiting, diarrhea or poor intake occurs. Advise adequate hydration.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
