Allergy medications treat symptoms caused by your immune system reacting to allergens like pollen, dust, or pet dander. The most common types are antihistamines, decongestants, nasal steroids, and mast cell stabilizers.
These drugs block or reduce histamine, a chemical your body releases during an allergic reaction. Histamine triggers symptoms like sneezing, itching, and runny nose. Some medications also reduce inflammation in nasal passages.
| Type | Examples | Common Uses |
|---|---|---|
| Antihistamines | Loratadine, Cetirizine, Fexofenadine | Mild to moderate symptoms, seasonal allergies |
| Decongestants | Pseudoephedrine, Phenylephrine | Nasal congestion, sinus pressure |
| Nasal Steroids | Fluticasone, Budesonide | Severe inflammation, chronic allergies |
| Mast Cell Stabilizers | Cromolyn Sodium | Preventing allergic reactions |
Antihistamines are often the first line of defense for seasonal allergies. Decongestants provide quick relief for stuffiness but shouldn't be used long-term. Nasal steroids work best for chronic inflammation but take a few days to start working. Mast cell stabilizers are less common but useful for preventing reactions.
Many people combine medications for better results. For example, someone with severe seasonal allergies might use a daily antihistamine plus a nasal steroid during peak pollen seasons. Always follow dosage instructions and consult a doctor if symptoms persist.
Many people think allergy shots (immunotherapy) are a medication, but they're actually a long-term treatment that helps your body build tolerance to specific allergens. They're not a quick fix but can reduce dependency on medications over time.
During spring, my seasonal allergies flare up with sneezing and itchy eyes. I take loratadine (an antihistamine) every morning and use fluticasone nasal spray before bed. This combination keeps my symptoms under control for most of the day. If I have particularly bad congestion, I'll add a decongestant for a few days-but never for more than a week.
For persistent or worsening symptoms, see an allergist. They can help identify specific triggers and recommend targeted treatments beyond over-the-counter options.
