How Does Diphenhydramine Work?
When you have an allergic reaction, your body releases histamine. This chemical binds to certain receptors, causing itching, swelling, and a runny nose. Diphenhydramine works by blocking these histamine receptors, which helps relieve these symptoms.
What Are the Effects of Diphenhydramine?
Diphenhydramine helps to reduce:
- Itching: Often caused by allergies like hives or insect bites.
- Sneezing: Commonly triggered by allergens such as pollen or dust.
- Runny Nose: Associated with conditions like allergic rhinitis.
In addition to its antihistamine effects, diphenhydramine can make you feel drowsy. This sedative effect is why Benadryl is sometimes used as a short-term sleep aid, although it’s best to use it for this purpose only with medical advice.

How Should Benadryl Be Used?
Follow the instructions on the Benadryl label or your healthcare provider’s advice. It’s important to stick to the recommended dosage to avoid side effects or interactions with other medications. Misusing or overdosing on diphenhydramine can be dangerous. For more information on the risks of overdose and toxicity, see Diphenhydramine Toxicity.
