What It Is and How It Works

Budesonide and formoterol fumarate dihydrate inhalation aerosol is a combination medication used to manage respiratory conditions such as asthma and COPD. Budesonide, a corticosteroid, helps reduce inflammation in the airways, while formoterol, a long-acting beta-agonist, aids in muscle relaxation around the airways to improve breathing.

Indications and Uses

This medication is primarily prescribed for individuals with moderate to severe persistent asthma or COPD that require both an inhaled corticosteroid and a long-acting bronchodilator. It is not intended for relief of acute bronchospasm or as a rescue inhaler.

Dosage Forms and General Dosing Considerations

The inhalation aerosol is available in multiple strengths. Your healthcare provider will determine the appropriate dosage based on your medical condition, response to treatment, and other medications you may be using. It is crucial to adhere to the prescribed schedule and not to adjust doses without consulting your physician.

How to Take It Correctly

  1. Shake the inhaler well before use.
  2. Remove the cap and check for debris.
  3. Exhale fully before placing the mouthpiece in your mouth.
  4. Inhale deeply while pressing down on the inhaler to release the medication.
  5. Hold your breath for about 10 seconds to allow the medication to reach deep into your lungs.
  6. Exhale slowly, and if a second dose is required, wait about a minute before repeating the process.

Contraindications and Precautions

Do not use this medication if you are allergic to budesonide, formoterol, or any other ingredients in the inhaler.

During pregnancy and breastfeeding, the risks and benefits should be discussed with your healthcare provider.

Drug, Food, and Supplement Interactions

Avoid using other long-acting beta-agonists in conjunction with budesonide and formoterol. Inform your healthcare provider about all medications, supplements, and herbal products you are taking, as interactions may occur. Grapefruit or grapefruit juice may interact with budesonide.
