How can Decongestant assist in the Treatment of Allergies?

Taking a decongestant is the safest way to treat nasal allergies. When you have an allergic reaction, your body will try to trap allergens by bringing more blood to the linings of your nose. This will result to inflammation and swelling, causing mucus production. This process (the combination of inflammation, swelling, mucus production) causes nasal congestion and reduces the airflow. Decongestants help open the nasal cavity and sinuses, allowing more air entry--often within minutes.

The main function of decongestants is to relieve stuffy noses and make it easier for you to breath. You can take them even after you have been exposed to allergen. They can be purchased over the counter or by your doctor's prescription. You can also get an allergy medication that is a combination of decongestants and antihistamines. If any of the combinations would not work, tell your doctor about it. There is a wide variety of combinations to choose from.

Decongestants are not recommended for people with heart problems, diabetes, high blood pressure, enlarged prostate, or an overactive thyroid. They are not also recommended to use these drugs for more than 3 days. Pregnant and nursing women are not also advised to take it. In addition, taking these drugs before going to bed is not recommended.
