✓ Pros: Non-sedating, 24-hour effect, chewable and liquid, suitable for ages 2+
✗ Cons: Not as fast-acting as cetirizine for some, can cause headache/less potent for nasal symptoms
Good first-line for mild symptoms, preferred in children who experienced drowsiness with cetirizine.
✓ Pros: Non-sedating, quick onset, approved down to 6 months (liquid)
✗ Cons: Bitter aftertaste, more expensive, less liquid choices
Useful for children with strong sedation on other antihistamines; cost may be a burden.
✓ Pros: Fast-acting
✗ Cons: Short duration, high sedation risk, not recommended routinely for children
Usually reserved for acute allergic reactions—avoid unless directed.
✓ Pros: Once-daily pill or chewable, may help with both allergy and asthma symptoms
✗ Cons: Black box warning for mental health side effects (see FDA), should be used under supervision
Consider only in children who don't respond to/are intolerant of antihistamines.
✓ Pros: No side effects, suitable for all ages, effective for congestion relief
✗ Cons: Only relieves nasal symptoms, does not address systemic allergy
Excellent for mild symptoms, can be used alongside medications.
✓ Pros: No side effects, can help reduce medication requirement
✗ Cons: Requires diligence, not always possible (e.g. pollen exposure)
Best for children with mild allergies or seasonal triggers.
✓ Pros: Reduces indoor allergen load
✗ Cons: Cost, not immediate effect
Particularly useful for dust/pet allergy.
Testing Convenience: Allergy testing typically requires a single appointment using either skin prick tests (15-20 minutes) or blood tests. Most pediatric allergists can test for 40+ common allergens simultaneously.
Home Management After Identification: Once specific allergens are identified, targeted environmental modifications often reduce symptoms more effectively than medications alone. For dust mites—the most common indoor allergen—simple changes include using allergen-proof mattress and pillow covers and washing bedding in hot water weekly. Pillow protection is particularly critical since children spend 8+ hours with their face directly against pillows, which become heavily infested with dust mites within months of use.
Common Childhood Allergens:
Progression Risk: Untreated environmental allergies in children may progress to asthma development. The "allergic march" describes how untreated allergic rhinitis can lead to lower airway inflammation and asthma symptoms. Addressing root causes through environmental control reduces this progression risk compared to symptom management alone.
