What are antihistamines

An over-the-counter or prescription drug known as an antihistamine works by blocking some of the effects that histamine has. Antihistamines are medications that inhibit or function against histamine because “anti” means “against.”.

What is histamine

Your body contains compounds called histamines that are involved in a number of processes. They serve as your private security detail. To keep you safe, your body gets rid of allergens when they are present.

The issue with allergies is that sometimes the things to which you are allergic appear to be unimportant. Yet because your immune system perceives them as a threat, it becomes activated and swiftly mounts an allergic reaction, which causes a wide range of allergy symptoms.

Histamines start the process that flushes allergens from your body or from your skin. Frequently, this process includes sneezing, redness, tearfulness, swelling, or itching. Your body’s defense mechanism operates in this manner. Everything is normal and designed with your safety and wellness in mind.
