Missed Dose Instructions
If you miss a dose, skip it and return to your regular dosing schedule. Do not take two doses at the same time or take extra doses to make up for the missed one.
Lifestyle & Tips

Reporting Side Effects
If you have questions about side effects or experience any side effects not listed here, contact your doctor for medical advice. You can also report side effects to the FDA at 1-800-332-1088 or online at https://www.fda.gov/medwatch.
Seek Immediate Medical Attention If You Experience:
- Sudden worsening of breathing or wheezing immediately after using the medication (paradoxical bronchospasm) - seek immediate medical attention.
- Chest pain, fast or irregular heartbeat, dizziness, or fainting.
- Severe headache or tremor.
- Signs of an allergic reaction (rash, hives, swelling of face/lips/tongue, difficulty breathing/swallowing).
Before Using This Medicine
It is essential to inform your doctor about the following:
Any allergies you have, including allergies to this medication, its components, or other substances, such as foods or drugs. Be sure to describe the symptoms you experienced.
If you have asthma, as this medication is not intended to treat asthma.
* If you are currently using a similar medication. If you are unsure, consult your doctor or pharmacist to determine if the medications are similar.
This list is not exhaustive, and it is crucial to discuss all your medications (including prescription, over-the-counter, natural products, and vitamins) and health conditions with your doctor and pharmacist. They will help you verify that it is safe to take this medication in conjunction with your other medications and health conditions.
Remember, do not initiate, discontinue, or modify the dosage of any medication without first consulting your doctor.
Precautions & Cautions
Immediately contact your doctor if you experience worsening breathing problems, if your rescue inhaler becomes less effective, or if you find yourself needing to use your rescue inhaler more frequently. Do not exceed the prescribed dose or use this medication more often than directed, as overdoses of this type of drug have been fatal. Consult with your doctor if you have any concerns.
Be aware that medications like this one may increase the risk of asthma-related deaths in individuals with asthma who are not also using an inhaled steroid. However, this risk does not appear to apply to people with Chronic Obstructive Pulmonary Disease (COPD). If you have questions or concerns, discuss them with your doctor.
If you are 65 years or older, exercise caution when using this drug, as you may be more susceptible to side effects. Additionally, if you are pregnant, planning to become pregnant, or are breastfeeding, inform your doctor. It is crucial to discuss the potential benefits and risks of this medication to both you and your baby.
Overdose Information
Overdose Symptoms:
- Chest pain
- Fast or irregular heartbeat (tachycardia, arrhythmias)
- Palpitations
- Tremor
- Nervousness
- Headache
- Dizziness
- Nausea
- Vomiting
- Hypokalemia (low potassium)
- Hyperglycemia (high blood sugar)
- Metabolic acidosis
What to Do:
Seek immediate medical attention or call Poison Control (1-800-222-1222). Treatment is supportive and symptomatic. Consider cardioselective beta-blockers with extreme caution in patients with bronchospasm.
Drug Interactions
Contraindicated Interactions
- Other long-acting beta2-adrenergic agonists (LABAs)
- Acute bronchospasm (as monotherapy)
Major Interactions
- Beta-blockers (especially non-selective): May block the bronchodilatory effect of arformoterol and produce severe bronchospasm.
- QTc-prolonging drugs (e.g., Class IA and III antiarrhythmics, macrolides, tricyclic antidepressants): Increased risk of ventricular arrhythmias.
- Diuretics (non-potassium sparing): May worsen ECG changes and/or hypokalemia.
Moderate Interactions
- Tricyclic antidepressants (TCAs) and Monoamine Oxidase Inhibitors (MAOIs): May potentiate the cardiovascular effects of arformoterol.
- Sympathomimetics: May potentiate adverse cardiovascular effects.
Minor Interactions
- Xanthine derivatives (e.g., theophylline): May potentiate hypokalemia.
Monitoring
Baseline Monitoring
Rationale: To establish baseline lung function and assess disease severity.
Timing: Prior to initiation
Rationale: To identify pre-existing cardiovascular conditions that may be exacerbated by LABAs.
Timing: Prior to initiation
Rationale: LABAs can cause hypokalemia, especially with concomitant diuretics or xanthines.
Timing: Prior to initiation, if risk factors present
Routine Monitoring
Frequency: Regularly (daily patient self-monitoring)
Target: Improvement or stability of symptoms
Action Threshold: Worsening symptoms, increased rescue inhaler use, or acute exacerbations require medical evaluation.
Frequency: Regularly (patient report)
Target: Absence or mild, tolerable effects
Action Threshold: Persistent or severe adverse effects, especially paradoxical bronchospasm, require immediate medical attention and discontinuation.
Frequency: Periodically (e.g., every 6-12 months or as clinically indicated)
Target: Maintenance or improvement of lung function
Action Threshold: Significant decline in FEV1 despite adherence.
Frequency: Periodically, if risk factors for hypokalemia or hyperglycemia are present (e.g., concomitant medications, diabetes)
Target: Within normal limits
Action Threshold: Abnormal levels requiring intervention.
Symptom Monitoring
- Worsening shortness of breath
- Increased wheezing
- Increased cough
- Chest tightness
- Increased need for rescue inhaler (short-acting beta-agonist)
- Paradoxical bronchospasm (immediate worsening of breathing after dose)
Special Patient Groups
Pregnancy
Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. Arformoterol is Pregnancy Category C.
Trimester-Specific Risks:
Lactation
It is not known whether arformoterol is excreted in human milk. Consider the developmental and health benefits of breastfeeding along with the mother's clinical need for arformoterol and any potential adverse effects on the breastfed infant from arformoterol or from the underlying maternal condition. A decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Pediatric Use
Safety and effectiveness have not been established in pediatric patients. Arformoterol is not indicated for use in children.
Geriatric Use
No dosage adjustment is required based on age. Clinical studies did not reveal differences in safety or effectiveness between elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Use with caution in elderly patients with cardiovascular disease or other comorbidities.
Clinical Information
Clinical Pearls
- Arformoterol is a maintenance medication for COPD; it is NOT a rescue inhaler for acute bronchospasm.
- Patients should always have a short-acting beta-agonist (SABA) available for acute symptoms.
- Emphasize the importance of twice-daily dosing, 12 hours apart, for consistent bronchodilation.
- Educate patients on the black box warning regarding increased risk of asthma-related death with LABAs, and clarify that arformoterol is for COPD, not asthma.
- Monitor for paradoxical bronchospasm, which requires immediate discontinuation and alternative therapy.
- Caution with concomitant use of beta-blockers, especially non-selective ones, as they can antagonize the bronchodilatory effect and cause severe bronchospasm.
Alternative Therapies
- Other LABAs (e.g., Salmeterol, Indacaterol, Olodaterol, Formoterol)
- Long-acting muscarinic antagonists (LAMAs) (e.g., Tiotropium, Aclidinium, Glycopyrronium, Umeclidinium)
- Inhaled corticosteroids (ICS) (often in combination with LABAs for COPD)
- Phosphodiesterase-4 (PDE4) inhibitors (e.g., Roflumilast) for severe COPD with chronic bronchitis and frequent exacerbations.
