What the FDA labels say about taking them together
Lanreotide and quinidine
Lanreotide's FDA label of October 11, 2024 names quinidine in its drug interactions section; the quinidine label PlainMeds reads does not name lanreotide. The lanreotide label: “Since it cannot be excluded that SOMATULINE DEPOT may have this effect, avoid other drugs mainly metabolized by CYP3A4 and which have a low therapeutic index.”
