This chart lists some of the medications used to treat allergies.

The conditions that can be treated with these medications include:
  • Seasonal allergic rhinitis (nasal allergies that occur for several weeks at a time)
  • Perennial allergic rhinitis (nasal allergies that occur throughout the year)
  • Itching (this symptom is present during many types of allergies)
  • Chronic Urticaria (hives that occur daily for longer than six weeks)

View Allergy Medications Table

Antihistamines
These block the action of histamine which results in a reduction of many allergic symptoms especially itching and mucus production.

Antihistamine/decongestants
These medications usually contain an antihistamine in combination with a decongestant.

Leukotriene antagonists
These medications block the action of leukotrienes, which can result in the reduction of various allergic symptoms such as mucus production.


FAQ
