Understanding Allergy and Hay Fever Medications (cont.)

What Are the Risks of Allergies?

In rare cases, an allergic reaction can be life-threatening, such as with asthma or anaphylaxis (see severe allergic reaction). However, most allergic reactions (for example, hay fever or conjunctivitis) are less serious.

Allergic rhinitis can be associated with other conditions, including asthma, atopic dermatitis, and nasal polyps. It can also have complications such as otitis media, eustachian tube dysfunction, sinusitis, and conjunctivitis. Symptoms of allergic rhinitis can in some cases contribute to or worsen learning difficulties, sleep disorders, and fatigue.
