postheadericon Drugs for Asthma and Allergies I

drugs for asthmaOver 50 million people in the United States suffer from asthma and allergies. Fortunately, today there are many effective medications to treat these diseases.

The following information is intended to help asthma and allergy sufferers better understand the most common types of drugs. Not intended to be a specific recommendation for treatment. You should consult your personal physician to choose the best treatment plan to control your allergy and asthma.

Antihistamines: If you are allergic, your doctor may prescribe an antihistamine to treat allergic rhinitis (“hay fever”) and other conditions such as urticaria.

Antihistamines may diminish the effects of histamine (a chemical produced by the body during an allergic reaction). By preventing the action of histamine, allergy symptoms can be reduced. Antihistamines come in liquid, tablet or nasal spray.

Antihistamines are divided into:

* “First-generation sedating” known to cause drowsiness in some people

* “Second-generation nonsedating moderate sedation” are much less likely to cause drowsiness

Possible side effects of antihistamines (often on antihistamines “first generation”):

* Dry mouth
* Difficulty urinating (especially in men with prostate problems)
* Constipation
* Drowsiness
* In some children: nightmares, unusual shock, restlessness, irritability

These symptoms are much less common with antihistamines “second generation.” Evaluate your doctor the potential benefits of using antihistamines against the possible side effects.

Decongestants: Decongestants reduce nasal congestion and other symptoms associated with allergies. Reduce the size of blood vessels, thus reducing the amount of fluid that falls in the lining of the nose and can cause congestion.

* They come in liquid, nasal sprays and tablets.
* Most can be acquired by prescription or nonprescription.
* Most commonly, antihistamines and decongestants are combined so that they can control most symptoms.

Possible side effects of decongestants:

* Nervousness
* Insomnia
* Increased blood pressure or heart rate
* The “rebound rhinitis” may occur with the spray if used for more than three or four days. This rebound nasal congestion worsens and can lead to a “dependency” of using the drug.
