No Interaction Expected

Glecaprevir/Pibrentasvir

Dextromethorphan

Summary:

Coadministration of dextromethorphan (30 mg single dose) and glecaprevir/pibrentasvir (300/120 mg once daily) decreased dextromethorphan Cmax and AUC by 30% and 25% (n=12). This was not clinically significant and no dose adjustment is required.

Description:

Drug-drug interaction studies were performed with dextromethorphan and showed no clinically significant interactions with Maviret.

Hello Lonnie84,

Wlodek has pointed you to the https://www.hep-druginteractions.org/checker which lets you check most interactions.

Maviret is Glecaprevir/Pibrentasvir

VICKS ® DayQuil ™ Cough – Cough & Congestion is Guaifenesin + Dextromethorphan

Guaifenesin is not covered but will be fine. Dextromethorphan is and it’s fine to take with Maviret.

Best of luck with your treatment. Maviret is a great combination, see: https://fixhepc.com/blog/item/132-maviret-mavyret-is-an-awesome-drug-for-hcv.html

YMMV
