Before taking this medicine

You should not use formoterol and mometasone if you are allergic to formoterol or mometasone.

Mometasone can weaken your immune system. Tell your doctor about any illness or infection you've had within the past several weeks.

Tell your doctor if you have ever had:

Tell your doctor if you are pregnant. It is not known whether this medicine will harm an unborn baby. However, having untreated or uncontrolled asthma during pregnancy may cause complications such as low birth weight, premature birth, or eclampsia (dangerously high blood pressure that can lead to medical problems in both mother and baby). The benefit of treating asthma may outweigh any risks to the baby.

It may take 1 or 2 weeks before your symptoms improve. Keep using the medication as directed and tell your doctor if your symptoms do not improve. Your doctor may tell you to stop using formoterol and mometasone once your asthma is well controlled.

Your dose needs may change due to surgery, illness, stress, or a recent asthma attack. Do not change your medication dose or schedule without your doctor's advice.

If you use a peak flow meter at home, tell your doctor if your numbers are lower than normal.

Your vision and your bone mineral density may need to be checked often.

Store at room temperature away from moisture and high heat. The canister may explode if it gets too hot. Do not puncture or burn an empty inhaler canister.

Store the 60-inhalation canister on its side, or with the mouthpiece down.

Once your asthma is under control, your doctor may want you to stop using this medicine. Do not stop using the medicine unless your doctor tells you to.
