Can promethazine cause neuroleptic malignant syndrome?

Answer:
YES! I was receiving promethazine (phenergan) to help stop pre term labor contractions while hospitalized for 10 weeks. I was given the drug periodicly when the contractions would get severe. It wasn't until about week 9 that I had neuroleptic malignant syndrome. Full body tremors, Temp of 104.9 and in and out of consciousness. It followed about one hour after a dose.
