The combination of promethazine hydrochloride, phenylephrine hydrochloride and codeine phosphate is contraindicated in pediatric patients less than 6 years of age, because the combination may cause fatal respiratory depression in this age population.
It is important that promethazine hydrochloride, phenylephrine hydrochloride and codeine phosphate syrup is measured with an accurate measuring device (see PRECAUTIONS-Information For Patients). A household teaspoon is not an accurate measuring device and could lead to overdosage, especially when half a teaspoon is to be measured. It is strongly recommended that an accurate measuring device be used. A pharmacist can provide an appropriate device and can provide instructions for measuring the correct dose.
