The Magic Of Antihistamine Drugs

Fexofenadine is used to treat many various types of allergies. It does this by inhibiting various chemicals or mechanisms that cause allergies to surface. When used in the prescribed manor under normal dosage, Fexofenadine can help reduce or even eliminate allergic reactions. Fexofenadine side effects may show up if more than normal dosage is given or if the drug has been used for a long period of time. Some side effects may be weak while others may be severe depending on the person and his body’s physiology.

Antihistamine drugs such as Fexofenadine can help prevent certain symptoms of allergic reactions from surfacing. Such symptoms include swelling, redness and rashes. Fexofenadine does this by blocking the action of histamine. A simple running nose can be stopped by blocking the channels that secrete the mucus. This allows for symptoms to be minimized. Fexofenadine side effects can occur when either too much or too little Fexofenadine has been administered. In some cases, they can occur due to genetic build up or due to the use of other medication.

There are certain side effects which are more normal and rather common amongst individuals who take an antihistamine drug such as Fexofenadine. Common Fexofenadine side effects include headaches, vomiting, diarrhea, back pain, fever, dizziness, indigestion, leg pain and the common cold. These effects can be minimized by taking other medication. In some cases, it is much better to control the symptoms as other medication can interfere with Fexofenadine.

Fexofenadine is available through prescription only which is a very effective and intellectual decision as this ensures people visit a licensed physician before taking the drug. This rule set in place to protect you and possibly eliminate certain severe adverse reaction occurrences due to the inability to yield to the drug’s precautions.

Whether you need to get rid of your allergies during a change of seasons or are the unfortunate victim of an allergic reaction that is irritating every fiber of your being, an antihistamine drug is your ticket out. Some antihistamines such as the oft recommended and praised Fexofenadine can help you overcome your problems with many different types of allergic reaction whether they are seasonal based, genetic or just some irritating allergy that your unfortunate body has yet to overcome.

Allergies – Antihistamines Part I

In this article we’re going to discuss probably the most common form of treatment for allergy sufferers; the use of antihistamines, what they are and how they work in the body to rid people of their allergy symptoms.

In this article we’re going to discuss probably the most common form of treatment for allergy sufferers; the use of antihistamines, what they are and how they work in the body to rid people of their allergy symptoms.

The first question most people ask about antihistamines is what they are. The reason is because when they see these little wonder pills advertised they are seeing the brand name and not what the pill actually is. The most popular brand names of antihistamines are Clarityn, Zyrtec, Allegra and Benadryl. There are plenty more though. The antihistamine industry is a multi billion dollar a year industry because of all the allergy sufferers but this still doesn’t tell us what an antihistamine is.

The best way to explain what an antihistamine is and what it does is to actually break the word down. Antihistamine is composed of two words, anti and histamine. Anti means to be against something or act against something. Which leaves us with what a histamine is. A histamine is something that your body produces in defense to an attack of allergens. It is these histamines that bring on the terrible symptoms of sneezing, itching, watery eyes, etc. that we suffer from when we are attacked by these allergens. Thus, an antihistamine is something that works against the histamines that our body produces.

Your common antihistamine comes in a little pill. How it actually works is quite amazing. What these pills do is release a chemical in our body that is very similar to and looks like a histamine to our body. These look-alike histamines make our body think that we basically have enough of these and keep the receptors in our body from working against them. In other words they stop the histamines in our body from working, thus relieving the symptoms.

What most people don’t know is that this is not the only function of histamines. They also play a very important role in the brain, keeping us attentive, alert and awake. So, if we stopped all of the histamines in the body from working we would basically fall asleep. This can be especially dangerous when driving a car or operating heavy machinery and in fact, this is exactly what happens when we take old antihistamines. So if you have any of these laying around in your home, please get rid of them and do not take them. Those expiration dates on antihistamines are there for a reason.

The good news is, newer forms of antihistamines have a much better effect on your allergies with less effect on your brain. How this is accomplished is actually very simple. Some medicines barely make it into the brain from the blood. This is actually not a good thing with antibiotics for brain infections. But when research workers figured this out they started to make antihistamines that also had the same properties as antibiotics, thus making it so that very little of the drug makes its way to the brain. If you read most antihistamine labels today it will say right on it, “non drowsy”.

In our next article in this series we’ll discuss the safety concerns of antihistamines.
