Simply put, histamines are released by the mast cells to fight off an allergen. The histamine promotes inflammation in several ways, causing allergic and asthmatic symptoms. Antihistamines are common medications used to fight the effects of the histamines. They are considered safe enough to be sold over the counter, with stronger versions prescribed by physicians. The antihistamine blocks the path of the histamine, thereby reducing your allergy symptoms.
Many new antihistamine medications are designed to be non-drowsy. But remember, everyone is different, and what may cause no side effects in one individual might cause noticeable effects in others. Antihistamines do not relieve stuffy noses, so they are sometimes paired with a decongestant.
Antihistamines are usually taken daily by mouth in the form of a pill, capsule or liquid. It is best to begin taking an antihistamine before the allergy season begins. This will give it time to bind to the H1 receptors for histamine before the actual histamine arrives.
If you have seasonal or environmental allergies, chances are there are times you would do anything to have a clear nose or eyes that don’t itch. Some people suffer from allergies throughout the entire year, while others experience symptoms seasonally, depending on the pollen type outside.
