Editorial Comment
Rilpivirine should not be co-administered with omeprazole as significant decreases in rilpivirine plasma concentrations may occur (due to gastric pH increase), which may result in loss of therapeutic effect of rilpivirine.
University of Liverpool Recommendation
These drugs should not be coadministered
