The mixture of promethazine hydrochloride and codeine phosphate is contraindicated in pediatric clients a lot less than six many years of age, simply because The mix may possibly result in fatal respiratory melancholy in this age population. It is necessary that promethazine hydrochloride and codeine phosphate syrup is measured having an precise measuring device (see Safety measures-Information and facts for Sufferers).
