Diphenhydramine is a first-generation antihistamine used to treat a number of conditions including allergic symptoms

and itchiness, the common cold, insomnia, motion sickness, and extrapyramidal symptoms. Diphenhydramine also has

local anesthetic properties, and has been used as such in people allergic to common local anesthetics such as

lidocaine.

Allergies

Diphenhydramine has been found to have a higher efficacy in treatment of allergies than some second-generation

antihistamines (such as desloratadine) but a similar efficacy with others (such as cetirizine).

Movement disorders

Diphenhydramine is used to treat Parkinson's disease-like extrapyramidal symptoms caused by antipsychotics.

Sleep

Because of its sedative properties, diphenhydramine is widely used in nonprescription sleep aids for insomnia. The drug is an ingredient in several products sold as sleep aids, either alone or in combination with other ingredients such as acetaminophen (paracetamol). An example of the latter is Tylenol PM. Diphenhydramine can cause minor psychological dependence. Diphenhydramine can cause sedation and has also been used as an anxiolytic.
