What Is Unisom?
Unisom is an OTC medication that contains the active ingredient doxylamine. It belongs to a family of drugs called antihistamines. The medication may cause drowsiness and thus can be taken by children over 12 years old and adults who have sleeping issues. The desired effects would last for around 6 hours. When purchasing Unisom, make sure to check the active ingredient. This is because some products may contain diphenhydramine instead of doxylamine. [2]
