Could someone please explain to me the meaning of the word "antihistamines"? I've referred to dictionaries, but am still not clear about its meaning. This word is often used in relation to cold, which is caused by histamines.
Many thanks.
Antihistamines are chemical substances such as over-the-counter medicines that help suppress allergic or common cold symptoms. Histamine is in dictionary as well.
"a chemical in the body which is released after an injury or during an allergic reaction."
So if you had received a bee-sting, a mild anti-histamine would help suppress the swelling that ordinarily would form. A strong anti-histamine might allow you to breathe more freely as your immune system tries to react to the allergen.
Thanks, Ragman.
So, if I've a severe cold, histamine is released in my body. Why is the reason for the presence of the histamine? Does it try to get rid of my cold condition or its presence worsens my cold so that an antihistamine will suppress the histamine to help me recover from my cold.
Do I get your correctly?
Many thanks.
I'm out of my depth to answer as I'm not a physician. Perhaps you can find your answer to that question by Google-ing the phrase 'immune system reaction to allergen' or `histamine reaction to allergen' or the like. Good luck.
Thanks, Ragman.
Thanks, Phoenix, for the link.
