Ertugliflozin and Dolutegravir Interaction
Drug interaction information between Ertugliflozin and Dolutegravir.
Ertugliflozin and Dolutegravir have a documented moderate interaction in FDA labeling.
FDA drug labeling documents a moderate-severity interaction between Ertugliflozin and Dolutegravir. 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
Dolutegravir blocks the kidneys from removing metformin from the body, which causes metformin levels to rise and increases the risk of side effects.
FDA Label Information
Drugs that Reduce Metformin Clearance Clinical Impact: The risk of lactic acidosis may increase due to concomitant use of drugs that interfere with common renal tubular transport systems involved in the renal elimination of metformin (e.g., organic cationic transporter-2 [OCT2] / multidrug and toxin extrusion [MATE] inhibitors such as ranolazine, vandetanib, dolutegravir, and cimetidine) which increase systemic exposure to metformin Intervention Consider the benefits and risks of concomitant use.

Frequently Asked Questions
What SPL severity band is on file for Ertugliflozin + Dolutegravir?
Compiled FDA labeling labels this pair moderate. That is a source-record field, not an individual medication-combination decision.
Which drug in this pair has the larger labeled-interaction portfolio?
Dolutegravir has 28 labeled pairs on file vs Ertugliflozin's 8. In the moderate band specifically: Ertugliflozin has 6 (also Metformin, Topiramate, Ranolazine, Cimetidine); Dolutegravir has 6 (also Empagliflozin, Empagliflozin/Linagliptin, Linagliptin, Metformin/Empagliflozin).
What mechanism field is on file for Ertugliflozin and Dolutegravir?
Dolutegravir blocks the kidneys from removing metformin from the body, which causes metformin levels to rise and increases the risk of side effects.
