Summary
Local anesthetics can cause methemoglobinemia, and chloroquine has been reported to rarely do so too. Combined exposure could theoretically raise risk, though systemic bupivacaine exposure from an implant is low.
What this interaction means in plain words
Bupivacaine implant and Chloroquine have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Additive oxidant-induced methemoglobin formation.
What to do
Monitor for cyanosis, dyspnea or low pulse-oximetry readings, particularly in patients with G6PD deficiency; treat methemoglobinemia with methylene blue if it occurs, avoiding it in G6PD deficiency.
