Antihistamine Decongestant used for Allergy Congestion

Why do allergies cause congestion? Allergies are annoying, and can cause congestion. When allergies begin, it is time to reach for an antihistamine. Some allergies are seasonal, yet they can strike any time of the year. What exactly is an antihistamine? When the body tries to fight outside substances, like ragweed, or pollen, the body goes into defense mode. The body produces histamines to fight the foreign substances, and in doing so it causes what is known as allergies. Although the body is trying to help, it does just the opposite. This could cause sneezing, itchy eyes, coughing, and sometimes asthma. The antihistamine is taken to fight the histamines so that relief can be obtained, and breathing can become easier again.

An antihistamine can be purchased over-the-counter in most instances, however there are still some antihistamines that require a written prescription. The severity of the allergy may determine which antihistamine is needed. People with seasonal, or occasional allergies usually experience great results with antihistamines.

Airborne Allergies

Airborne allergies can cause nasal passages to swell, making it hard to breath, and sometimes can even cause infection to set in. Because allergies are usually airborne, the nasal passages and sinuses are the first places to get attached. When this happens, congestion frequently occurs. All nasal congestion is not related to allergies, and if taking an antihistamine does not supply relief, it may be time to check in with the doctor.

Food Allergies

One thing people don't always take into consideration is food allergies. Food allergies can also cause nasal congestion. This type of allergy takes detailed testing to see what the allergies are, and how they should be treated.

About Allergies and Antihistamine Effectiveness

For regular allergies there are ways to help the antihistamine do a better job. By keeping the household dusted and bathroom, and other molds at bay, the antihistamine has less of a battle to fight. For most people the problem stems from sources outside the home, but any kind substance can cause irritation.

Taking an antihistamine gives relief usually in a couple of hours, and if the antihistamine is a 24 hour pill, then relief is good all day and night. After taking antihistamines, for a long period of time, you may find that the relief from the antihistamine has diminished. There is a simple answer and solution for that problem.

After a while, the body becomes immune to the antihistamine, and the antihistamine is no longer effective. The amount of time before this happens is after three months of using an antihistamine. Never take more than the recommended dosage to see if the results would be better. The simple answer is to rotate the antihistamine being taken with a new antihistamine. Safety is the number one concern, when taking any kind of medication.

The allergy battle is an old one, and one that will probably never go away. Be responsible when taking an antihistamine because some of them have a side effect, which is drowsiness. Taking a good antihistamine is a great way to fight allergy symptoms and feel better.
