How to Use Antihistamines to Treat Dust Mite Allergies

The use of common, over-the-counter antihistamines can be quite effective in reducing or eliminating symptoms of dust mite allergies. Dust mites, which are microscopic organisms that live in dust particles, emit waste material than can cause such symptoms as nasal and chest congestion, wheezing, watery eyes, sneezing and coughing.

Things You'll Need

• Antihistamines
• Doctor or allergist

Instructions

1. Investigate the first-generation antihistamines, such as Benadryl and Chlor-Timetron, to treat dust mite allergies. These antihistamines are generally available without a prescription, and can be quite effective in relieving chest congestion, wheezing, watery eyes and sneezing. Note that a majority of first-generation antihistamines cause drowsiness, and may be inappropriate for daytime use.

2. See your doctor or allergist about finding the right antihistamines to treat dust mite allergies. Many of the current prescription antihistamines, known as second-generation antihistamines, are extremely effective in reducing or eliminating the symptoms of a dust mite allergy. If you choose to use an over-the-counter antihistamine, you may want to check with your doctor to note any negative interactions with any other prescription medications you may be taking.

3. Choose an antihistamine to treat dust mite allergies according to how long it will relieve your symptoms. Some of the newer antihistamines on the market, such as Zyrtec and Allegra, can relieve symptoms for up to 24 hours. Antihistamines with shorter duration periods may be effective when using natural remedies to treat the symptoms of dust mite allergies.

4. Pick an antihistamine to treat dust mite allergies based upon whether it has been designed for daytime or nighttime use. Many second-generation antihistamines contain non-drowsiness formulas to keep you focused during the day. An antihistamine that causes drowsiness, however, may be more effective for use while you are sleeping, when dust mite allergy symptoms can be the most severe.

5. Follow up with your doctor or allergist on the results you are getting with any type of antihistamine. You may want to discuss your strategy for controlling the dust mite population in your home in order to feel even more relief from allergy symptoms. If the side effects of antihistamines become too severe, notify your healthcare professional immediately.

• Second-generation antihistamines such as Zyrtec and Clarinex can be taken by children as young as 6 months.
