Frequently asked questions

What is Numark Sleep Aid used for?+
Numark Sleep Aid contains diphenhydramine hydrochloride, a first‑generation antihistamine that is used primarily to help adults with short‑term insomnia fall asleep. It is also employed to relieve symptoms of motion sickness and allergic rhinitis that can interfere with sleep.
How does diphenhydramine work to promote sleep?+
Diphenhydramine blocks H1 histamine receptors in the brain, reducing the wake‑promoting effects of histamine. Its ability to cross the blood‑brain barrier also produces anticholinergic activity, which together create a sedative‑hypnotic effect that helps initiate and maintain sleep.
What is the usual dose of Numark Sleep Aid?+
The appropriate dose of Numark Sleep Aid is determined by a qualified prescriber based on the individual’s age, medical condition, and response to therapy. Patients should follow the prescribing information and not exceed the recommended amount.
