- promazine
Interactions between your drugs
promazine succinylcholine
Applies to: promazine, Anectine Flo-Pack (succinylcholine)
MONITOR: The combination of succinylcholine and promazine may lengthen the duration of neuromuscular blockade. Prolonged apnea has been reported in one case. The proposed mechanism is promazine-induced inhibition of plasma cholinesterase.
MANAGEMENT: Patients should be monitored for prolonged neuromuscular blockade if they are given promazine after receiving succinylcholine.

Drug and food interactions
promazine food
Applies to: promazine
GENERALLY AVOID: Concurrent use of ethanol and phenothiazines may result in additive CNS depression and psychomotor impairment. Also, ethanol may precipitate dystonic reactions in patients who are taking phenothiazines. The two drugs probably act on different sites in the brain, although the exact mechanism of the interaction is not known.
MANAGEMENT: Patients should be advised to avoid alcohol during phenothiazine therapy.
