Patient Education

Diphenhydramine Injection


Diphenhydramine injection is used to treat allergic reactions, especially for people who are unable to take diphenhydramine by mouth. It is used also to treat motion sickness. Diphenhydramine injection is also used alone or along with other medications to control abnormal movements in people who have Parkinsonian syndrome (a disorder of the nervous system that causes difficulties with movement, muscle control, and balance). Diphenhydramine injection should not be used in newborn or premature infants. Diphenhydramine injection is in a class of medications called antihistamines. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms.
