Allergy Medication Comparison: Find the Right Relief for Your Symptoms

When your nose runs, your eyes itch, and you can’t breathe right, not all allergy medication, drugs used to reduce allergic reactions like sneezing, runny nose, and itchy eyes. Also known as antihistamines, it works by blocking histamine, the chemical your body releases during an allergic reaction. is the same. Some make you sleepy. Others dry out your mouth. A few don’t work at all for your specific triggers. The right choice depends on your symptoms, lifestyle, and what side effects you can tolerate.

There are three main types you’ll see on shelves or in prescriptions: antihistamines, oral or nasal drugs that block histamine to reduce itching, sneezing, and runny nose. Also known as first-generation and second-generation antihistamines, they range from old-school sedating pills like diphenhydramine to non-drowsy options like loratadine and cetirizine.. Then there are nasal corticosteroids, sprays that reduce inflammation in the nasal passages to tackle congestion, runny nose, and sneezing long-term. Also known as steroid nasal sprays, they’re the most effective for persistent allergies but take days to build up.. And finally, decongestants, medications that shrink swollen blood vessels in the nose to open up airways quickly. Also known as nasal decongestants or oral decongestants, they give fast relief but aren’t safe for long-term use or people with high blood pressure.. You don’t need all three. Many people do best with one or two combined—like a non-drowsy antihistamine plus a nasal spray. Others need to avoid decongestants entirely because of heart issues or sleep problems.

What works for your coworker might leave you worse off. If you drive for a living, you need a non-sedating antihistamine. If you’re stuck with year-round congestion, a nasal spray beats popping pills every day. If your eyes swell shut, you might need something stronger than what’s sold over the counter.
