Editorial Comment
Coadministration may decrease dolutegravir concentrations due to complex binding to polyvalent ions (chelation). It is recommended to administer dolutegravir 2 hours before or 6 hours after taking the supplements containing polyvalent cations. Although the magnitude of the decrease in doluteravir concentrations may be ameliorated by taking dolutegravir and supplements together with food, there no data on zinc supplements specifically.
University of Liverpool Recommendation
Potential interaction - may require close monitoring, alteration of drug dosage or timing of administration
