What medical treatments are used for allergies and hay fever?

Although not always possible, attempt to avoid contact with known or suspected allergens.

If symptoms persist, a doctor or health care professional may prescribe a prescription-strength medication. The following sections discuss some common medications for allergies and hay fever.
