There are many uses for antihistamines. Taken orally or used as a cream, antihistamine stops allergic reactions. Allergic reactions can come from pollen, or even insects bites. Antihistamine is a chemical component that blocks the body from developing histamine. Histamine is an agent the body naturally produces when a foreign agent enters the body and the body responds by trying to fight it off with histamine, which leads us to develop allergic reactions such as watery eyes or rashes. Antihistamine tries to stop the body from producing histamine, which in turn, stops the allergic reaction.
How a Antihistamine Cream is Used
Antihistamine can be taken orally or placed on the body as a cream. Usually, antihistamine is taken orally to fight off seasonal allergies. Many people use an antihistamine cream to cure insect bites, rashes, burns or minor skin irritations. An antihistamine cream can cure a rash from poison ivy and relieve a skin burn. Antihistamine cream works by stopping excess production of histamine, thereby reducing the symptoms of the insect bite or rash. An antihistamine cream treats the rash once it is placed on top of the irritant. Most creams are rubbed in. As the effects of antihistamine are short lived, it is wise to apply the antihistamine cream on the source of the rash often.
When to use an Antihistamine Cream
An antihistamine cream can aid in situations where there is an insect bite. When someone is bit, the spot of skin becomes inflamed and itchy. This happens because histamine causes antibodies to go to the site of the bite to fight off infection. The rise in antibodies causes the site of the insect bite to become inflamed. Antihistamine cream, when applied to the site of the insect bite, stops the production of histamine, thereby stopping the site from being invaded by antibodies and stopping the insect bite from becoming inflamed. Since an antihistamine cream relieves itchiness, the insect bite also is alleviated from itch.
Skin Irritations and Antihistamine Use
Skin itching can arise from allergies to insect bites. Similar to the production of histamine, skin itching arises when skin receptors inform the immune system of an invading threat and the immune system responds by creating itchiness on the skin. When applied on the site of skin irritation, an antihistamine cream reduces the skin's itchiness. This produces a sense of relief and temporary break from itches on the skin.
How the Antihistamine Cream Works
Used for medical purposes, it convinces the body that a foreign agent, such as pollen or insect bite, is not a threat to the body and stops the effects of an allergic reaction. Antihistamines block the production of histamine and stop the immune system from creating skin itchiness. This medication can be taken orally or used as a cream. When used as a cream, it relieves insect bites, sunburns, minor cuts, rashes, minor burns, scrapes and other mild skin irritations. Antihistamine cream is placed on the site of irrational, stopping the body from trying to attack the foreign agent. When the body stops attacking the foreign agent, the symptoms of an allergic reaction decrease.
