Foradil capsules are for oral inhalation only and must be used with the Aerolizer inhaler device. The capsules should never be swallowed.

• Preparation: Do not remove a Foradil capsule from its blister pack until immediately before use.
  
  
• Loading: The capsule is placed into the capsule chamber of the Aerolizer inhaler.
  
  
• Piercing: The inhaler has buttons that, when pressed once, pierce the capsule to release the powder.
  
  
• Inhalation: The patient exhales fully (away from the inhaler), then places the mouthpiece in their mouth, and inhales quickly and deeply to draw the powder into the lungs. You should hear a “whirring” noise as the capsule spins.
  
  
• Confirmation: After inhalation, open the device to check if all powder has been inhaled. If not, repeat the inhalation process.
  
  
• Disposal: The empty capsule should be discarded after use.
  
  
• Dosing Schedule:
  
  
  • For Asthma and COPD: The usual dose is the contents of one 12 mcg capsule inhaled every 12 hours (morning and evening). The two doses should be approximately 12 hours apart. The total daily dose should not exceed one capsule twice daily (24 mcg total daily dose).
  • For Exercise-Induced Bronchospasm (EIB): One 12 mcg capsule inhaled at least 15 minutes before exercise, as needed. Do not use more often than every 12 hours. If you are already using Foradil twice daily for asthma/COPD, do not use an additional dose for EIB prevention; use your rescue inhaler if needed.
• Important: Foradil does not provide immediate relief. Always have a rescue inhaler for sudden symptoms.
  
  
• Method: Oral inhalation using the Aerolizer device.
  
  
• Capsule Use: Never swallow; use immediately after opening blister.
  
  
• Dosing: Once every 12 hours for asthma/COPD; as needed before exercise for EIB.
  
  
• Key Reminder: Not a rescue inhaler.
  
  

Foradil (formoterol) works by selectively stimulating beta2-adrenergic receptors, which are found predominantly in the smooth muscles surrounding the airways in the lungs. When formoterol binds to these receptors, it activates an enzyme called adenylyl cyclase. This leads to an increase in intracellular cyclic adenosine monophosphate (cAMP) levels. Increased cAMP causes the relaxation of bronchial smooth muscle, leading to bronchodilation (widening of the airways). This makes it easier for air to flow in and out of the lungs, reducing symptoms like wheezing, shortness of breath, and chest tightness.

Formoterol is classified as a “long-acting” bronchodilator because its effects can last for up to 12 hours, allowing for twice-daily dosing. Its onset of action is relatively rapid (within 2-3 minutes), which is why it can also be used for EIB prevention.

• Mechanism: Selective beta2-adrenergic receptor agonist.
• Action: Stimulates receptors in lung airways, leading to increased cAMP.
• Result: Relaxation of bronchial smooth muscle and bronchodilation.
• Duration: Long-acting (up to 12 hours), rapid onset (2-3 minutes).

Like all medications, Foradil can cause side effects. Patients should be aware of these and report any concerning symptoms to their healthcare provider.

• Common Side Effects:
  
  
  • Headache
  • Nervousness, tremor, or shakiness
  • Dizziness
  • Throat irritation, dry mouth
  • Nausea, vomiting, diarrhea
  • Muscle cramps
  • Insomnia (difficulty sleeping)
  • Cough, stuffy or runny nose, sore throat
  • Viral infection, cold symptoms
• Serious Side Effects (Seek immediate medical attention if these occur):
  
  
  • Paradoxical Bronchospasm: Worsening of breathing, wheezing, or difficulty breathing immediately after inhalation. This is rare but requires immediate discontinuation and use of a rescue inhaler.
  • Serious Asthma-Related Events: Although Foradil helps control asthma, LABAs have been associated with an increased risk of asthma-related death and hospitalization, particularly when used without an inhaled corticosteroid.
  • Cardiovascular Effects: Fast, pounding, or irregular heartbeat (palpitations, tachycardia), chest pain, high blood pressure.
  • Hypokalemia: Low potassium levels, which can manifest as muscle weakness, cramps, or abnormal heart rhythms.
  • Hyperglycemia: Increased blood sugar levels.
  • Allergic Reactions: Rash, hives, itching, swelling of the face, tongue, or throat, difficulty breathing or swallowing.
  • Seizures
• Common: Headache, tremor, nervousness, dizziness, dry mouth, GI upset, muscle cramps.
  
  
• Serious: Paradoxical bronchospasm, asthma-related death/hospitalization risk, cardiovascular effects, hypokalemia, hyperglycemia, allergic reactions, seizures.
  
  

Action: Immediate medical attention for serious symptoms.

Several important warnings and precautions are associated with Foradil due to its class as a LABA.

• Asthma-Related Death Risk (Black Box Warning): LABA medications, including formoterol, increase the risk of asthma-related death. Therefore, Foradil should only be used as additional therapy for asthma patients who are currently taking but are inadequately controlled on a long-term asthma control medication (e.g., an inhaled corticosteroid). It is not for patients whose asthma is adequately controlled on low or medium-dose inhaled corticosteroids alone. When asthma control is achieved, a doctor may consider discontinuing Foradil if possible, while continuing the inhaled corticosteroid.
  
  
• Not for Acute Symptoms: Foradil is NOT a rescue medication. It should not be used to treat sudden, acute symptoms of asthma or COPD.
  
  
• Not a Substitute for Corticosteroids: Foradil is not a substitute for inhaled or oral corticosteroids. Patients should continue their steroid medications as prescribed and not stop or reduce them when starting Foradil.
  
  
• Worsening Asthma/COPD: Do not start Foradil during an episode of rapidly worsening asthma or COPD. If symptoms worsen while on Foradil, contact your healthcare provider immediately.
  
  

Cardiovascular Conditions: Use with caution in patients with heart problems (e.g., coronary insufficiency, cardiac arrhythmias, high blood pressure), as LABAs can affect heart rate and blood pressure.

• For Asthma and COPD: The usual dose is the contents of one 12 mcg capsule inhaled every 12 hours (morning and evening). The two doses should be approximately 12 hours apart. The total daily dose should not exceed one capsule twice daily (24 mcg total daily dose).
• For Exercise-Induced Bronchospasm (EIB): One 12 mcg capsule inhaled at least 15 minutes before exercise, as needed. Do not use more often than every 12 hours. If you are already using Foradil twice daily for asthma/COPD, do not use an additional dose for EIB prevention; use your rescue inhaler if needed.

• Important: Foradil does not provide immediate relief. Always have a rescue inhaler for sudden symptoms.
  
  
• Method: Oral inhalation using the Aerolizer device.
  
  
• Capsule Use: Never swallow; use immediately after opening blister.
  
  
• Dosing: Once every 12 hours for asthma/COPD; as needed before exercise for EIB.
  
  
• Key Reminder: Not a rescue inhaler.
  
  

The dosage of Foradil is precisely prescribed by a healthcare professional and must be strictly followed.

• For Asthma (Adults and Children ≥ 5 years):
  • Inhale the contents of one 12 mcg Foradil capsule using the Aerolizer inhaler every 12 hours (morning and evening).
  • Always used in addition to a long-term asthma control medicine (e.g., inhaled corticosteroid).
  • Maximum daily dose: 24 mcg (one capsule twice daily).
• For Exercise-Induced Bronchospasm (EIB) (Adults and Children ≥ 5 years):
  • Inhale the contents of one 12 mcg Foradil capsule using the Aerolizer inhaler at least 15 minutes before exercise, as needed.
  • Do not use more often than every 12 hours.
  • If already on twice-daily Foradil for asthma, do not use an additional dose for EIB.
• For COPD (Adults):
  • Inhale the contents of one 12 mcg Foradil capsule using the Aerolizer inhaler every 12 hours (morning and evening).
  • Maximum daily dose: 24 mcg (one capsule twice daily).

Important: Do not exceed the prescribed dose or frequency. If symptoms worsen or you need your rescue inhaler more often, contact your doctor immediately.

• Standard Dose: 12 mcg per capsule.
• Frequency: Usually every 12 hours for maintenance; as needed for EIB.
• Maximum: 24 mcg total daily dose.
• Guidance: Always follow physician’s instructions precisely.

Foradil (formoterol fumarate) is a prescription-only medication. It is not available over-the-counter.

The strict prescription requirement is due to:

• Risk Profile: The potential for serious side effects, including the increased risk of asthma-related death when used inappropriately for asthma.
• Specific Indications: It is used for chronic respiratory conditions that require careful diagnosis and ongoing management by a physician.
• Adherence to Treatment Protocols: Proper use of Foradil often involves combination therapy (especially for asthma with an inhaled corticosteroid), and a doctor ensures the patient understands and adheres to the complete treatment plan.
• Monitoring: While not requiring frequent blood tests like some other drugs, patients on Foradil need regular medical follow-ups to assess asthma/COPD control, monitor for side effects, and ensure appropriate use.
• Patient Education: It’s critical for patients to understand that Foradil is not a rescue inhaler and that they must continue their other prescribed controller medications.

Therefore, Foradil must be prescribed and its use supervised by a qualified healthcare professional, such as a pulmonologist, allergist, or general practitioner experienced in managing asthma and COPD.
