1. What Aerius is and what it is used for

What Aerius is

Aerius contains desloratadine, which is an antihistamine.

How Aerius works

Aerius is a non-drowsy antiallergic medicine that helps control allergic reactions and their symptoms.

When to use Aerius

Aerius relieves the symptoms associated with allergic rhinitis (inflammation of the nasal passages caused by an allergy, such as hay fever or house dust mite allergy) in adults and adolescents aged 12 years and older. These symptoms include sneezing, runny or itchy nose, itchy palate, and itchy, red, or watery eyes.

Aerius is also used to relieve the symptoms associated with urticaria (a skin condition caused by an allergy). These symptoms include itching and skin rashes.

Relief from these symptoms lasts a full day and helps you to continue your daily activities and normal sleep periods.

2. What you need to know before you take Aerius

Do not take Aerius

  • if you are allergic to desloratadine or any of the other ingredients of this medicine (listed in section 6) or to loratadine.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before taking Aerius:

  • if you have impaired kidney function.
  • if you have a history of seizures.

Children and adolescents

Do not give this medicine to children under 12 years of age.

Other medicines and Aerius

There are no known interactions between Aerius and other medicines.

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Taking Aerius with food, drinks, and alcohol

Aerius can be taken with or without food.

Be careful when taking Aerius with alcohol.

Pregnancy, breastfeeding, and fertility

Aerius is not recommended if you are pregnant or breastfeeding.

No data are available on male and female fertility.

Driving and using machines

At the recommended dose, this medicine is not expected to affect your ability to drive or use machines. Although most people do not experience drowsiness, it is recommended not to engage in activities that require a state of alertness, such as driving a car or using machinery, until you have determined your own response to the medicine.

Aerius tablets contain lactose

3. How to take Aerius

Follow exactly the instructions given to you by your doctor or pharmacist. If you are not sure, ask your doctor or pharmacist again.

Use in adults and adolescents aged 12 and over

The recommended dose is one tablet once daily with water, with or without food.

This medicine is for oral use.

Swallow the tablet whole.

Regarding the duration of treatment, your doctor will determine the type of allergic rhinitis you have and for how long you should take Aerius.

If your allergic rhinitis is intermittent (symptoms present for less than 4 days a week or for less than 4 weeks), your doctor will recommend a treatment schedule based on the evaluation of your disease history.

If your allergic rhinitis is persistent (symptoms present for 4 or more days a week and for more than 4 weeks), your doctor may recommend long-term treatment.

For urticaria, the duration of treatment may vary from one patient to another, and you should follow your doctor's instructions.

If you take more Aerius than you should

Take Aerius only as directed by your doctor. An accidental overdose is not expected to cause serious problems. However, if you take more Aerius than you should, tell your doctor, pharmacist, or nurse immediately.
