Several types of nonprescription medications can help ease allergy symptoms. They include:

• Oral antihistamines. Antihistamines can help relieve sneezing, itching, a runny nose and watery eyes. Examples of oral antihistamines include loratadine (Claritin, Alavert), cetirizine (Zyrtec Allergy) and fexofenadine (Allegra Allergy).
• Decongestants. Oral decongestants such as pseudoephedrine (Sudafed, Afrinol, others) can provide temporary relief from nasal stuffiness. Decongestants also come in nasal sprays, such as oxymetazoline (Afrin) and phenylephrine (Neo-Synephrine). Only use nasal decongestants for a few days in a row. Longer-term use of decongestant nasal sprays can actually worsen symptoms (rebound congestion).
• Nasal spray. Cromolyn sodium nasal spray can ease allergy symptoms and doesn't have serious side effects, though it's most effective when you begin using it before your symptoms start.
• Combination medications. Some allergy medications combine an antihistamine with a decongestant. Examples include loratadine-pseudoephedrine (Claritin-D) and fexofenadine-pseudoephedrine (Allegra-D).
