Reporting Side Effects
This list is not exhaustive, and you may experience other side effects. If you have questions or concerns, contact your doctor. 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:
- Worsening shortness of breath or wheezing

- Signs of an allergic reaction (rash, hives, swelling of face/lips/tongue, difficulty breathing)
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. Be sure to describe the allergic reaction and its symptoms.
If you have asthma, as this medication is not intended to treat this condition.
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 is not an exhaustive list of all potential interactions with this medication. Therefore, it is crucial to discuss the following with your doctor and pharmacist:
All prescription and over-the-counter medications you are taking
Any natural products or vitamins you are using
Your overall health and any existing medical conditions
To ensure your safety, carefully review all your medications and health conditions with your doctor before taking this medication. Never start, stop, or adjust the dosage of any medication without first consulting your doctor.
Precautions & Cautions
If you experience worsening breathing problems, a decrease in the effectiveness of your rescue inhaler, or an increased need to use your rescue inhaler, contact your doctor immediately. Do not exceed the prescribed dose or frequency of this medication, as overdoses of this type of drug have been fatal. Consult with your doctor if you have any concerns.
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 medication, as you may be more susceptible to side effects. If you are pregnant, planning to become pregnant, or breastfeeding, inform your doctor to discuss the potential benefits and risks to both you and your baby.
Overdose Information
Overdose Symptoms:
- Tachycardia (fast heart rate)
- Arrhythmias (irregular heartbeat)
- Palpitations
- Myocardial ischemia (chest pain)
- Hypertension or hypotension
- Tremor
- Nervousness
- Headache
- Nausea
- Dizziness
- Fatigue

What to Do:
Seek immediate medical attention. Treatment is supportive and symptomatic. Consider judicious use of a cardioselective beta-blocker, but only with extreme caution in patients with a history of bronchospasm. Call 1-800-222-1222 (Poison Control).

Monitoring
Baseline Monitoring
Rationale: To assess baseline lung function and severity of COPD.
Timing: Prior to initiation of therapy.
Rationale: To identify pre-existing cardiovascular conditions due to potential adrenergic effects.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline, as beta2-agonists can cause hypokalemia.
Timing: Prior to initiation of therapy, especially in patients at risk.
Rationale: To establish baseline, as beta2-agonists can cause hyperglycemia.
Timing: Prior to initiation of therapy, especially in diabetic patients.
Routine Monitoring
Frequency: Regularly, at each visit
Target: Stable symptoms, no increase in rescue inhaler use
Action Threshold: Increased shortness of breath, increased cough, increased sputum, increased rescue inhaler use; consider alternative or additional therapy.
Frequency: Periodically, or if symptoms arise
Target: Within normal limits for patient
Action Threshold: Significant tachycardia, palpitations, arrhythmias, or hypertension; consider dose adjustment or discontinuation.
Frequency: Periodically, especially in patients at risk or on concomitant diuretics
Target: 3.5-5.0 mEq/L
Action Threshold: Hypokalemia (<3.5 mEq/L); consider supplementation or alternative therapy.
Frequency: Periodically, especially in diabetic patients
Target: Individualized glycemic targets
Action Threshold: Significant hyperglycemia; adjust diabetes management.
Symptom Monitoring
- Worsening shortness of breath
- Increased cough
- Increased sputum production
- Increased use of rescue inhaler
- Chest pain or discomfort
- Palpitations
- Tremor
- Nervousness
- Muscle cramps
Special Patient Groups
Pregnancy
Category C. There are no adequate and well-controlled studies of arformoterol in pregnant women. Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. Beta2-agonists may interfere with uterine contractility.
Trimester-Specific Risks:
Lactation
It is not known whether arformoterol is excreted in human milk. Caution should be exercised when arformoterol is administered to a nursing woman. The developmental and health benefits of breastfeeding should be considered along with the motherβs clinical need for arformoterol and any potential adverse effects on the breastfed infant from arformoterol or from the underlying maternal condition.
Pediatric Use
Safety and effectiveness in pediatric patients (under 18 years of age) have not been established. Arformoterol is not indicated for use in children.
Geriatric Use
No overall differences in safety or effectiveness have been observed between elderly and younger patients. However, caution should be exercised in elderly patients due to the greater frequency of decreased hepatic, renal, or cardiac function, and concomitant disease or other drug therapy.
Clinical Information
Clinical Pearls
- Arformoterol is a maintenance bronchodilator for COPD; it is NOT a rescue medication for acute bronchospasm.
- Patients should always have a short-acting beta2-agonist (SABA) available for acute symptoms.
- The black box warning for LABAs regarding asthma-related death applies to the class, even though arformoterol is indicated only for COPD.
- Administer twice daily, approximately 12 hours apart, using a nebulizer.
- Monitor for cardiovascular adverse effects (tachycardia, palpitations, hypertension) and metabolic effects (hypokalemia, hyperglycemia), especially in susceptible patients.
- Avoid concomitant use with other LABAs or non-selective beta-blockers.
Alternative Therapies
- Other LABAs (e.g., formoterol, salmeterol, indacaterol, olodaterol, vilanterol)
- Long-acting muscarinic antagonists (LAMAs) (e.g., tiotropium, aclidinium, glycopyrronium, umeclidinium)
- Short-acting beta2-agonists (SABAs) for rescue (e.g., albuterol, levalbuterol)
- Short-acting muscarinic antagonists (SAMAs) for rescue (e.g., ipratropium)
- Methylxanthines (e.g., theophylline) - less commonly used due to narrow therapeutic index.
