Octreotide should not be used in combination with cyclosporine, cimetidine, bromocriptine, quinidine, terfenadine and other drugs. 1. Cyclosporine and cimetidine: Octreotide may decrease the intestinal absorption of cyclosporine and delay the intestinal absorption of cimetidine, so the combination should be avoided. 2. Bromocriptine: Octreotide may increase the bioavailability of bromocriptine, and its combination is not recommended. 3. Quinidine, terfenadine: a few data show that octreotide should be avoided in combination with quinidine, terfenadine and other drugs. The above drugs should be used under the guidance of specialized physicians. If there is any discomfort, consult a doctor in time, use the drugs under the doctor’s guidance for treatment, and avoid abusing the drugs on your own.
