Metaproterenol aerosol

Generic Name: metaproterenol (met-a-proe-TER-e-nol)
Brand Name: Alupent

Metaproterenol aerosol is used for:

Treating or preventing symptoms of asthma, emphysema, bronchitis, and other reversible breathing problems. It may also be used for other conditions as determined by your doctor.

Metaproterenol aerosol is a beta-adrenergic agonist bronchodilator. It works by relaxing the smooth muscle in the airways, allowing air to flow in and out of the lungs more easily.

Do NOT use metaproterenol aerosol if:

  • you are allergic to any ingredient in metaproterenol aerosol
  • you have had an unexpected reaction to another sympathomimetic (eg, albuterol, pseudoephedrine)
  • you have a fast heartbeat
  • you are taking another beta-adrenergic bronchodilator (eg, albuterol) or droxidopa

Contact your doctor or health care provider right away if any of these apply to you.

Before using metaproterenol aerosol:

Some medical conditions may interact with metaproterenol aerosol. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:

  • if you are pregnant, planning to become pregnant, or are breast-feeding
  • if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
  • if you have allergies to medicines, foods, or other substances
  • if you have heart problems (eg, irregular heartbeat, congestive heart failure) or high blood pressure
  • if you have a history of seizures (eg, epilepsy), diabetes, an overactive thyroid, or have an adrenal gland tumor (eg, pheochromocytoma)

Some MEDICINES MAY INTERACT with metaproterenol aerosol. Tell your health care provider if you are taking any other medicines, especially any of the following:

  • Beta-blockers (eg, propranolol) because the effectiveness of metaproterenol aerosol may be decreased
  • Beta-adrenergic bronchodilators (eg, albuterol), catechol-O-methyltransferase (COMT) inhibitors (eg, entacapone), monoamine oxidase (MAO) inhibitors (eg, phenelzine), sympathomimetics (eg, pseudoephedrine), or tricyclic antidepressants (eg, amitriptyline) because side effects may be increased by metaproterenol aerosol
  • Droxidopa because the risk of side effects, such as irregular heartbeat or heart attack, may be increased

This may not be a complete list of all interactions that may occur. Ask your health care provider if metaproterenol aerosol may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
