Allegra is used for treating seasonal allergy symptoms such as sneezing, runny nose, itchy throat, or itchy, watery eyes. It is also used to treat hives and skin itching. Allegra is an antihistamine. It works by blocking a substance in the body called histamine. This helps to decrease allergy symptoms.
Use Allegra as directed by your doctor.
- Take Allegra by mouth with or without food.
- Take Allegra with a full glass of water (8 oz/240 mL).
- Do not drink fruit juice at the same time as you take Allegra. Certain fruit juices (eg, grapefruit, apple, orange) may decrease Allegra’s effectiveness.
