This report displays the potential drug interactions for the following 2 drugs:
- dolutegravir
- Xenical (orlistat)
Interactions between your drugs
orlistat dolutegravir
Applies to: Xenical (orlistat) and dolutegravir
MONITOR: Orlistat may theoretically reduce the gastrointestinal absorption and therapeutic efficacy of antiretroviral agents. The mechanism may involve retention of lipophilic medicines in the gastrointestinal tract or reduced gastrointestinal tract transit time. Data have been reported for efavirenz and lopinavir. Other antiretroviral agents may also be affected.
MANAGEMENT: The potential reduction in antiretroviral efficacy should be considered before initiating treatment with orlistat. Patients who take antiretroviral medications should be advised to consult their physician before using the non-prescription brand of orlistat.

Drug and food interactions
dolutegravir food
Applies to: dolutegravir
Food increases the extent of absorption and slows the rate of absorption of dolutegravir. When administered with a low-, moderate- or high-fat meal, dolutegravir peak plasma concentration (Cmax) increased by 46%, 52% and 67%, systemic exposure (AUC) increased by 33%, 41% and 66%, and time to reach Cmax (Tmax) increased from 2 hours to 3, 4 and 5 hours, respectively, compared to administration under fasted conditions. Dolutegravir may be taken with or without food.
