Ref #2824 : * Dolutegravir administered 2 hours before the antacid.
Dolutegravir should not be taken together with Maalox or any antacids containing significant amounts of metal cations. Administration of antacid (Maalox) 2 hours after dolutegravir attenuated the impact of antacid. The mean C24h of 0.56μg/mL with a 2 hour separation of antacid represents a value of 5.6-fold above the PA-IC90. It is recommended that dolutegravir should be administered 2 hours before or 6 hours after antacids.
