Astepro is an antihistamine that reduces the effects of natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.

Astepro Nasal Spray prevents sneezing, itching, runny nose, and other nasal symptoms of allergies.

Astepro Nasal Spray is used for treating seasonal allergies in adults and children who are at least 2 years old, and for year-round allergies in adults and children as young as 6 months old.

Astepro Nasal Spray may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert. Before using this medicine, tell your doctor if you regularly use other medicines that make you sleepy (such as cold or allergy medicine, sedatives, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression, or anxiety). They can add to sleepiness caused by Astepro.

Drinking alcohol can increase certain side effects of Astepro. Call your doctor if your symptoms do not improve, or if they get worse while using Astepro. Stop using this medicine and call your doctor at once if you have fast or uneven heartbeats, tightness in your chest, or if you feel short of breath.

Use Astepro nasal spray exactly as directed on the label, or as prescribed by your doctor.

Before your first use, squeeze the bottle 2 or more times away from your face, until a fine mist appears. Repeat this whenever the nasal spray hasn't been used for longer than 3 days.

Do not allow a young child to use this medicine without help from an adult.
