The most common medications for mild allergy relief help prevent runny noses, sneezing and itchiness.

How do antihistamines work?

The body can react to an allergen by producing substances called histamines, which can cause a runny nose, sneezing, scratchy throat, rashes and itchy, watery eyes. Antihistamines work to lessen these symptoms by blocking the histamines in the body.

Can I limit sleepiness and other side effects?

You may be able to limit some side effects by choosing certain products, such as non-drowsy antihistamines or an over-the-counter glycerin mouth rinse to help ease dry mouth.



These widely used medications provide temporary relief of nasal, sinus and ear tube congestion.

How do decongestants work?

Decongestants help to shrink blood vessels and tissues in the nose that have become swollen because of allergies. Decongestants can help a stuffed nose, but they don't help relieve sneezing or itching.

What are common side effects?

Decongestants might cause a jittery or nervous feeling, a rapid heartbeat, a rise in blood pressure or effects that make it difficult to sleep.

Intranasal Steroid Sprays

These effective nasal sprays treat inflammation and help relieve congestion, sneezing and a runny or itchy nose.

How do intranasal steroid sprays work?

24 hour nasal allergy sprays are considered to be the most effective medication for people with moderate to severe nasal allergies. Sprays treat inflammation and help relieve nasal allergy symptoms, including congestion.

Are they available over the counter?

Nasacort, a 24 hour full prescription strength nasal allergy spray, is now available over the counter. Consult your pharmacist or doctor to see if this medication is right for you.
