Runny nose
Nasal congestion
Itchy nose
Itchy or watery eyes
Post-nasal drip
💡 Most patients do best using a combination of medications tailored to their specific symptoms. Your provider can help you build the right regimen.

Advantages
- Fast symptom relief
- Good for breakthrough symptoms
Possible Side Effects
- Bitter taste
- Mild drowsiness
Block leukotrienes — inflammatory chemicals involved in both allergies and asthma. Particularly useful for patients with both nasal allergies and asthma, and for nighttime symptoms.

Reduce nasal congestion by shrinking swollen blood vessels. Effective but important limitations apply — these should not be used as a long-term solution.
Examples
- Pseudoephedrine (oral)
- Oxymetazoline nasal spray (Afrin)
Use For
- Acute nasal congestion relief
- Short-term only
⚠️ Important warnings: Oral decongestants may raise blood pressure — use with caution if you have hypertension. Nasal decongestant sprays like oxymetazoline (Afrin) should not be used for more than 3 days — longer use causes rebound congestion that can be worse than the original symptoms.

Tips for Better Allergy Control
📅Start medications before allergy season begins — don't wait for symptoms to peak
💧Use nasal steroid sprays every day during allergy season, not just on bad days
🚫Avoid known allergy triggers when possible — check pollen counts on high-symptom days
🌊Rinse the nose with saline spray to clear allergens and reduce congestion

When to See an Allergy Specialist
You may benefit from a specialist visit if:
- Symptoms persist despite using medications as directed
- You have severe or year-round nasal congestion
- You develop asthma symptoms such as wheezing or chest tightness
- You are interested in allergy immunotherapy (allergy shots or sublingual drops) — a long-term treatment that can reduce or eliminate the underlying allergy
