Benadryl: Health Benefits & Risks
What are the health benefits of Benadryl?
Benadryl, also known by its generic name diphenhydramine, is an antihistamine medication that is used to relieve symptoms of allergies, hay fever, and the common cold such as itching, watery eyes, runny nose, and sneezing. It can also be used to relieve symptoms of allergic skin reactions, insomnia, motion sickness, and as a mild sedative.
The health benefits of Benadryl include:
- Allergy relief: Benadryl can effectively reduce symptoms of allergic reactions, such as itching, sneezing, runny nose, and watery eyes, by blocking the action of histamine, a substance in the body that causes these symptoms.
- Motion sickness: Benadryl can be used to alleviate symptoms of motion sickness, such as nausea, vomiting, and dizziness, by acting on the brain to reduce feelings of motion sickness.
- Mild sedative: Benadryl has a sedating effect and can be used to induce sleep or to reduce anxiety and tension. It is often used as a sleep aid in over-the-counter medications.
- Relief from itching: Benadryl can help relieve itching associated with allergic reactions, insect bites, and skin conditions like eczema and hives.
- Reduction of symptoms from the common cold: Benadryl can help reduce symptoms of the common cold, such as sneezing and runny nose, by drying up nasal secretions.
It’s important to note that while Benadryl can be effective for these purposes, it can also cause drowsiness and impair your ability to perform tasks that require alertness, such as driving. It’s important to use Benadryl only as directed and to talk to your healthcare provider before using it, especially if you have any underlying health conditions or are taking other medications.
