Major

zinc sulfate cabotegravir

Applies to: trace elements with selenium and iodide and cabotegravir

ADJUST DOSING INTERVAL: Coadministration with antacids, mineral supplements, or other medications containing polyvalent cations such as magnesium, aluminum, calcium, and iron may decrease the bioavailability of oral cabotegravir. The proposed mechanism involves chelation of cabotegravir by polyvalent cations, forming a complex that is poorly absorbed from the gastrointestinal tract. The interaction has not been studied with cabotegravir, but has been reported with other integrase strand transfer inhibitors (INSTIs).

MANAGEMENT: To minimize the risk of reduced viral susceptibility and resistance development associated with subtherapeutic levels of cabotegravir, medications containing polyvalent cations such as antacids and mineral supplements should be administered at least 2 hours before or 4 hours after the oral cabotegravir dose.

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.
