Introduction
Allergies affect millions of people worldwide, causing symptoms like sneezing, itching, and runny nose. Many individuals rely on antihistamines to manage these symptoms effectively. Lorphenadine is a second-generation antihistamine commonly used to relieve allergy symptoms. It works by blocking histamine, a substance in the body that triggers allergic reactions.
This article explores Lorphenadine’s uses, dosage, benefits, side effects, and comparisons with other antihistamines.
What is Lorphenadine?
It is classified as a non-drowsy antihistamine, meaning it provides relief from allergy symptoms without causing significant sleepiness. It is primarily used for treating:
- Seasonal allergies (hay fever)
- Year-round allergies (perennial allergic rhinitis)
- Skin conditions like hives and rashes
Unlike first-generation antihistamines, Lorphenadine has a lower risk of drowsiness, making it a preferred choice for individuals who need to stay active during the day.
How Lorphenadine Works
Histamine is a chemical released by the immune system when the body detects an allergen. This chemical binds to histamine receptors, triggering symptoms such as:
- Sneezing
- Runny nose
- Itchy and watery eyes
- Skin rashes and swelling
It functions by blocking H1 histamine receptors, preventing histamine from causing these allergic reactions. This makes it an effective medication for allergy relief.
