Allergy Medicines That Are Commonly Prescribed

An allergy takes place when your body's susceptible immune system reacts to a substance called allergen. Allergens are substances that actually trigger an allergic reaction in a person with a weak, underdeveloped or exaggerated immune system. In healthy people with a strong immune system, these allergens do not cause any allergic reactions.

The physiological mechanism of various allergic reactions is quite same. Allergens invade the body through inhalation, skin contact, or oral ingestion. The immune system tends to combat these allergensand during this process, an allergic reaction takes place, causing inflammation and irritation. The white blood cells (WBCs) release antibodies that bind to the mast cells, which break out and release histamine.

Histamine is a chemical that is released during an allergic reaction. It produces inflammation and symptoms such as frequent sneezing, runny or stuffy nose, itchy or watery eyes, scratchy throat, and skin rashes. In some highly susceptible people, a severe allergic reaction can lead to swelling of the face and throat, breathing difficulties, and asthma.

Common Allergy Medicines Prescribed By Doctors

Antihistamines

Antihistamines are common allergy medicines prescribed for seasonal allergies, urticaria, and allergic rhinitis. They are often categorized under sedating and non-sedating drugs. First generation, or older, antihistamines cause more dizziness and sleepiness, while second generation, or newer, antihistamines cause less sedation; however, some may experience mild drowsiness.

All antihistamines act in the same way – reducing the secretion of histamine. They are particularly useful in eradicating the symptoms of allergic rhinitis, or hay fever. They are available in pills, sprays, eye drops, ointments and creams. Generic Allegra (Fexofenadine), Generic Claritin (Loratadine) and Generic Zyrtec (Cetirizine) are some of the common over-the-counter antihistamines. Generic Xyzal (Levocetirizine) and Generic Clarinex (Desloratadine) are prescription antihistamines.

Decongestants

Decongestants are prescribed to relieve stuffy nose by dilating the blood vessels, limiting the amount of nasal secretion. They are available in pills, nasal sprays and liquids. However, they do not provide relief from skin itching and sneezing.

Steroids

Steroids are often prescribed to reduce inflammation. They come in tablets, injectable, topical creams, nasal sprays and eye preparations. Generic Omnaris (Ciclesonide) and Generic Flonase (Fluticasone) are commonly prescribed steroid-based nasal sprays.

Leukotriene Inhibitors

Another substance that triggers an allergic reaction is leukotriene that aggravates allergic symptoms and asthma. These medicines target leukotriene receptors to eradicate allergic symptoms. Generic Singulair (Montelukast) is one of the most commonly prescribed allergy medicines.

Mast Cell Stabilizers

Mast cell stabilizers are usually prescribed to prevent allergic reactions. When an allergic reaction takes place, mast cells secrete histamine that triggers allergies. Cromolyn sodium is one of the mast stabilizers that can prevent and treat allergy.

Immunomodulators

Immunomodulators are available in topical preparations prescribed to treat skin allergies like urticarial rash. They are advised when antihistamines and other allergy medicines fail to subside allergic symptoms.

These allergy medications are certainly helpful and effective. You can use any of these medications after consulting with a doctor. This will help use the any allergy medicine appropriately and safely. Make sure you do not use them overtly, as overdose can cause side effects.
