Allergies and Asthma


Itchy, red, watery eyes? Runny nose? Yep, you may be suffering from allergies.

When you have allergies, you may be sensitive to a variety of common substances, such as pollen, mold, animal dander, or dust. Seasonal allergies, often referred to as “hay fever,” are caused by reactions to types of pollen found in trees, grass, flowers, and weeds. When exposed to any of these pollens, an allergy sufferer may experience sneezing and runny nose (allergic rhinitis), itchy or watery eyes (allergic conjunctivitis), itching of the skin, or hives. Allergy medicines aim to prevent or relieve many of these symptoms.

Allergy Treatments

There are several types of OTC allergy medicines to choose from depending on the type, timing, and severity of your symptoms, as well as your personal treatment needs and preferences: antihistamines, corticosteroids, decongestants, mast cell stabilizers, combinations, and homeopathics.


Antihistamines work by blocking the histamines that cause allergic symptoms. These medicines are often used to treat seasonal or year-round nasal and eye allergies and they are found in the form of oral pills, tabs or liquids, eye drops, nasal sprays, and topical creams and ointments.

OTC antihistamines:


These medicines aim to reduce allergic symptoms including inflammation and swelling which can cause a stuffy, runny, and itchy nose. OTC corticosteroids are mostly found in the form of nasal sprays, topical creams, and ointments. These nasal sprays can be indicated for seasonal or year-round nasal and ocular allergies. The creams and ointments are used to relieve skin itchiness and stop the spread of rashes. (Note that corticosteroids are not the same as anabolic steroids.)

OTC corticosteroids
  • Hydrocortisone
    Cortaid®, Cortizone 10®, Dermarest®, Itch-X®, Preparation H®, Tucks®


These medicines reduce nasal and sinus stuffiness by shrinking swollen membranes, which can be a common symptom of allergies. OTC decongestants are found in the form of pills, liquids, inhalants, nasal sprays, and drops. Decongestants are often also combined with other OTC allergy treatment ingredients in combination products.

Shortness of breath? Wheezing? A person who suffers from bronchial asthma has very sensitive air passages (bronchi) that may be affected by a number of different things called triggers. These triggers include food, medicine, pets, smoke or other irritants in the air, the common cold, and exercise. When exposed to a trigger, a person may experience shortness of breath, tightness in the chest, or wheezing. OTC asthma medicines, also known as bronchodilators, are used to help relieve breathing problems caused by bronchial asthma.

Asthma Treatments

Bronchodilator asthma medicines work by opening air passages that are narrowed during asthma attacks. Asthma medicine active ingredients are available in tablet form and are taken by mouth.

Asthma medicines may also contain other active ingredients to relieve additional conditions, such as chest congestion and the build-up of mucus.
