There are 2 alcohol/food/lifestyle interactions with Tivicay (dolutegravir).

Major

Multivitamins With Minerals Dolutegravir

Major Drug Interaction

ADJUST DOSING INTERVAL: Coadministration with medications containing polyvalent cations such as aluminum, calcium, iron, or magnesium may decrease the oral bioavailability of dolutegravir. The mechanism of interaction likely involves chelation of dolutegravir by the polyvalent cation in the gastrointestinal tract. In 16 study subjects, administration of a single 50 mg dose of dolutegravir simultaneously with an antacid containing magnesium and aluminum decreased dolutegravir peak plasma concentration (Cmax), systemic exposure (AUC) and trough plasma concentration (Cmin; 24 hours post-dose) by 72%, 74% and 74%, respectively, compared to administration without the antacid. When the antacid was administered 2 hours after dolutegravir, the Cmax, AUC and Cmin of dolutegravir decreased by just 18%, 26% and 30%, respectively. Administration of single-dose dolutegravir simultaneously with a multivitamin decreased the Cmax, AUC and Cmin of dolutegravir by 35%, 33% and 32%, respectively. Coadministration of dolutegravir with calcium carbonate or ferrous fumarate under fed conditions counteracted the interaction and provided plasma exposures comparable to dolutegravir alone under fasted conditions.

MANAGEMENT: Dolutegravir should be administered 2 hours before or 6 hours after medications containing polyvalent cations such as antacids, laxatives, or mineral supplements. When taken with food, dolutegravir and supplements or multivitamins containing calcium or iron can be taken at the same time.

Minor

Dolutegravir Food

Minor Food Interaction

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.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
