Lithium and Azilsartan Interaction
Drug interaction information between Lithium and Azilsartan.
Lithium and Azilsartan have a documented moderate interaction in FDA labeling.
FDA drug labeling documents a moderate-severity interaction between Lithium and Azilsartan. This page displays the available source-record category and label text. The category is not an individual risk estimate or medication-combination direction.
How They Interact
Azilsartan can make it harder for the kidneys to remove lithium from the body. This causes lithium levels to build up, which can lead to dangerous side effects.

Frequently Asked Questions
What SPL severity band is on file for Lithium + Azilsartan?

Which drug in this pair has the larger labeled-interaction portfolio?
Lithium has 90 labeled pairs on file vs Azilsartan's 3. In the moderate band specifically: Lithium has 23 (also Amiloride, Amiodarone, Amlodipine/Valsartan, Benazepril); Azilsartan has 2 (also Chlorthalidone).
What mechanism field is on file for Lithium and Azilsartan?
Azilsartan can make it harder for the kidneys to remove lithium from the body. This causes lithium levels to build up, which can lead to dangerous side effects.
