Overdose Information
Overdose Symptoms:
- Exaggerated beta-adrenergic effects (e.g., tachycardia, palpitations, tremor, nervousness, headache, nausea, dizziness, hypokalemia, hyperglycemia)
- Exaggerated anticholinergic effects (e.g., dry mouth, blurred vision, urinary retention, constipation, increased heart rate)
What to Do:
Seek immediate medical attention or call a poison control center (1-800-222-1222). Treatment is supportive and symptomatic. Consider cardiovascular monitoring and potassium levels.
Drug Interactions
Major Interactions
- Other anticholinergics (e.g., tiotropium, aclidinium, umeclidinium): Increased risk of anticholinergic adverse effects.
- Beta-blockers (non-selective): May antagonize the bronchodilatory effect of albuterol and cause severe bronchospasm.
- Monoamine Oxidase Inhibitors (MAOIs) and Tricyclic Antidepressants (TCAs): May potentiate the cardiovascular effects of albuterol (e.g., increased heart rate, blood pressure).
- Diuretics (non-potassium sparing, e.g., thiazides, loop diuretics): May worsen ECG changes and/or hypokalemia induced by beta-agonists.
Moderate Interactions
- Sympathomimetics (e.g., pseudoephedrine, phenylephrine): Additive cardiovascular effects.
- Digoxin: Albuterol may decrease serum digoxin levels.
- Other short-acting beta-agonists: Increased risk of adverse cardiovascular effects.
Monitoring
Baseline Monitoring
Rationale: To establish baseline lung function and assess disease severity.
Timing: Prior to initiation of therapy.
Rationale: Albuterol can cause cardiovascular effects; assess baseline status, especially in patients with pre-existing cardiac conditions.
Timing: Prior to initiation of therapy.
Rationale: Ipratropium can precipitate or worsen narrow-angle glaucoma. Assess baseline in patients at risk.
Timing: Prior to initiation of therapy in at-risk patients.
Routine Monitoring
Frequency: Periodically (e.g., every 3-12 months or as clinically indicated)
Target: Improvement from baseline, individualized goals.
Action Threshold: Lack of improvement or worsening of lung function may indicate inadequate control or disease progression.
Frequency: Periodically, or as clinically indicated, especially during dose titration or in patients with cardiovascular comorbidities.
Target: Within normal limits or patient's baseline.
Action Threshold: Significant tachycardia, palpitations, or hypertension may require dose adjustment or discontinuation.
Frequency: Periodically, especially in patients receiving concomitant diuretics or corticosteroids, or with severe exacerbations.
Target: 3.5-5.0 mEq/L
Action Threshold: Hypokalemia (<3.5 mEq/L) may require supplementation or dose adjustment.
Frequency: Regularly (e.g., daily symptom diary)
Target: Reduced frequency and severity of symptoms (e.g., dyspnea, cough, wheezing).
Action Threshold: Increased use of rescue inhaler, worsening symptoms, or nocturnal awakenings indicate inadequate control.
Symptom Monitoring
- Worsening shortness of breath
- Increased wheezing or coughing
- Chest tightness
- Increased need for rescue inhaler
- Palpitations or rapid heart rate
- Tremor or nervousness
- Dry mouth
- Blurred vision or eye pain (especially in patients with glaucoma)
- Difficulty urinating (especially in men with prostatic hyperplasia)
Special Patient Groups
Pregnancy
Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. Both ipratropium and albuterol have been shown to be teratogenic in animal studies at high doses. Albuterol can inhibit uterine contractions.
Trimester-Specific Risks:
Lactation
Both ipratropium and albuterol are excreted in human milk. Caution should be exercised when Duoneb is administered to a nursing mother. The decision to discontinue nursing or to discontinue the drug should take into account the importance of the drug to the mother.
Pediatric Use
Safety and efficacy have not been established in pediatric patients under 6 years of age. Use in children 6-11 years old is off-label and should be done with caution and careful monitoring. For patients 12 years and older, adult dosing applies.
Geriatric Use
Use with caution in elderly patients, as they may be more susceptible to the cardiovascular effects of albuterol (e.g., tachycardia, arrhythmias) and the anticholinergic effects of ipratropium (e.g., urinary retention, glaucoma exacerbation). Monitor for these adverse effects.
Clinical Information
Clinical Pearls
- Duoneb is a maintenance bronchodilator for COPD and is not indicated for the initial treatment of acute episodes of bronchospasm where additional doses of a short-acting bronchodilator are required.
- Patients should be instructed on the proper use of the nebulizer and the importance of avoiding contact of the solution with the eyes to prevent ocular adverse events.
- Paradoxical bronchospasm can occur with any inhaled bronchodilator; if it occurs, discontinue Duoneb immediately and institute alternative therapy.
- Monitor for signs of hypokalemia, especially in patients with severe COPD, during acute exacerbations, or with concomitant use of diuretics or corticosteroids.
- Advise patients to seek immediate medical attention if their breathing problems worsen or if they need to use their rescue inhaler more often than usual.
Alternative Therapies
- Short-acting beta-agonists (SABAs) monotherapy (e.g., albuterol, levalbuterol)
- Short-acting muscarinic antagonists (SAMAs) monotherapy (e.g., ipratropium)
- Long-acting beta-agonists (LABAs) monotherapy (e.g., salmeterol, formoterol)
- Long-acting muscarinic antagonists (LAMAs) monotherapy (e.g., tiotropium, aclidinium, umeclidinium)
- Inhaled corticosteroids (ICS) (often in combination with LABA for asthma or severe COPD)
- Oral corticosteroids (for exacerbations)
- Phosphodiesterase-4 (PDE4) inhibitors (e.g., roflumilast for severe COPD)
