1. What NightAid Tablets are and what are they used
for?
NightAid Tablets contain the following active
ingredient: Diphenhydramine hydrochloride.
Diphenhydramine hydrochloride is an antihistamine
which works by blocking the body’s response to
histamine, which is an agent responsible for causing
allergic responses such as hay fever, stings and rashes.
Histamine is also involved in the brain’s waking
system so diphenhydramine hydrochloride can help
alleviate temporary sleeplessness.
