If you will be using this medicine for a long time, it is important that your doctor check your or your child's progress at regular visits. This will allow your doctor to see if the medicine is working properly and to check for any unwanted effects.

This medicine should not be used together with other inhaled medicines that are similar, such as albuterol (Accuneb®), isoproterenol (Isuprel®), metaproterenol (Alupent®), pirbuterol (Maxair®), or terbutaline (Brethaire®).

This medicine may cause paradoxical bronchospasm, which means your breathing or wheezing will get worse. Paradoxical bronchospasm may be life-threatening. Check with your doctor right away if you or your child have coughing, difficulty breathing, shortness of breath, or wheezing after using this medicine.

Talk to your doctor or get medical help right away if:

  • Your inhaler does not seem to be working as well as usual and you need to use it more often.

You or your child may also be taking an antiinflammatory medicine, such as a steroid (cortisone-like medicine), together with this medicine. Do not stop taking the antiinflammatory medicine, even if your asthma seems better, unless you are told to do so by your doctor.

Levalbuterol may cause serious types of allergic reactions, including anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Check with your doctor right away if you or your child develop a skin rash, hives, itching, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you are using this medicine.

Hypokalemia (low potassium in the blood) may occur while you are using this medicine. Check with your doctor right away if you or your child have more than one of the following symptoms: convulsions, decreased urine, dry mouth, increased thirst, irregular heartbeat, loss of appetite, mood changes, muscle pain or cramps, nausea or vomiting, numbness or tingling in the hands, feet, or lips, shortness of breath, or unusual tiredness or weakness.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems, and herbal or vitamin supplements.
