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

• Oral antihistamines. Antihistamines can help relieve sneezing, itching, a stuffy or runny nose, and watery eyes. Examples of oral antihistamines include cetirizine (Zyrtec Allergy), fexofenadine (Allegra Allergy) and loratadine (Claritin, Alavert).
• Corticosteroid nasal sprays. These medications improve nasal symptoms. Examples include fluticasone propionate (Flonase Allergy Relief), budesonide (Rhinocort Allergy) and triamcinolone (Nasacort Allergy 24 Hour). Talk to your health care provider about long-term use of corticosteroid nasal sprays.
• Cromolyn sodium nasal spray. This nasal spray can ease allergy symptoms by blocking the release of immune system agents that cause symptoms. It works best if treatment is started before exposure to allergens. It's considered a very safe treatment, but it usually needs to be used 4 to 6 times daily.
• Oral decongestants. Oral decongestants such as pseudoephedrine (Sudafed) can provide temporary relief from nasal stuffiness. Some allergy medications combine an antihistamine with a decongestant. Examples include cetirizine-pseudoephedrine (Zyrtec-D 12 Hour), fexofenadine-pseudoephedrine (Allegra-D 12 Hour Allergy and Congestion) and loratadine-pseudoephedrine (Claritin-D). Talk to your health care provider about whether the use of a decongestant is good for treating your allergy symptoms.
