Diphenhydramine works by blocking the effects of histamine, a naturally occurring chemical in the body that is responsible for allergic reactions.

For adults and children 12 years and older, the usual oral dose is 25 to 50 mg every 4 to 6 hours as needed. For children 6 to 11 years old, the usual dose is 12.5 to 25 mg every 4 to 6 hours as needed. It is important to follow the instructions provided by the healthcare provider or the directions on the packaging.

If any of these occur, it is important to seek medical attention immediately.

It is essential to note that Diphenhydramine can interact with other medications, including certain antidepressants, sedatives, and anti-anxiety drugs. It is crucial to consult with a healthcare professional before taking Diphenhydramine alongside other medications.
