Benadryl is an oral tablet made up of diphenhydramine (an antihistamine). We carry the brand name Benadryl in 25mg and 50mg.

Benadryl is used to fight cold and allergy symptoms. It can also be used to treat motion sickness, to help induce sleep, and also helps treat some symptoms of Parkinson’s disease. Symptoms that Benadryl helps relieve include watery eyes, stuffy nose, runny nose, sneezing, hives, and many other symptoms.

Benadryl is an antihistamine which means it works by reducing the effect of histamine produced in the body. Histamines are naturally produced and once released, produce many different effects within the body. This includes the contraction of smooth muscle tissues of the lungs, uterus, and stomach, the stimulation of gastric acid secretion in the stomach, the acceleration of heart rate, and also serves as a neurotransmitter, carrying chemical messages between nerve cells.

Always follow directions given to you by your doctor.

Take Benadryl as needed.

Swallow capsule whole, do not try to break the capsule.

Drink with water.


Tell your doctor about all medications you are currently taking including prescription, over-the-counter, vitamins, and herbal remedies before taking Benadryl.
