A recipe for compounding promethazine gel with a final concentra-tion of 12.5 mg/mL is available at the Pharmacy Times Com-pounding Hotline Web site (see "Suggested Reading"). Topical application of medication is an effective method for drug delivery. However, the amount of medication absorbed through the skin is influenced by skin type, thickness of skin, and the area of applica-tion. Absorption can also be influenced by temperature and the addition of occlusive dressing to the area of application.

into the general circulation. In the case of overdosage, drug expo-sure can be prolonged. The benefits of topical administration of promethazine should be weighed against the variability of drug absorption through this route.”
