Overdose Information
Overdose Symptoms:
- Chest pain
- Fast or irregular heartbeat
- Severe tremor or nervousness
- Headache
- Dizziness
- Nausea
- Weakness
- Seizures
- Hypokalemia (low potassium)
- Hyperglycemia (high blood sugar)
- Adrenal suppression (with chronic overdose)
What to Do:
Seek immediate medical attention. Call 911 or your local poison control center (1-800-222-1222 in the US). Treatment is supportive and symptomatic. Monitor cardiac function, serum potassium, and blood glucose levels.
Drug Interactions
Contraindicated Interactions
- Strong CYP3A4 inhibitors (e.g., ritonavir, ketoconazole, itraconazole, clarithromycin, telithromycin, nefazodone) - concomitant use is not recommended due to increased systemic exposure to fluticasone and salmeterol, leading to increased risk of cardiovascular and systemic corticosteroid adverse effects.
Major Interactions
- Beta-blockers (e.g., propranolol, carvedilol) - may block the bronchodilatory effect of salmeterol and produce severe bronchospasm, especially in patients with asthma. Generally, patients with asthma should not be treated with beta-blockers.
- Diuretics (e.g., furosemide, hydrochlorothiazide) - may potentiate ECG changes and/or hypokalemia associated with LABAs, especially at high doses.
- Tricyclic antidepressants (TCAs) and Monoamine Oxidase Inhibitors (MAOIs) (e.g., amitriptyline, phenelzine) - may potentiate the effect of salmeterol on the cardiovascular system. Use with extreme caution or avoid within 2 weeks of discontinuing MAOIs/TCAs.
Moderate Interactions
- Other sympathomimetics - may potentiate adverse cardiovascular effects.
- Non-potassium-sparing diuretics - may worsen ECG changes and/or hypokalemia.
Minor Interactions
- Not specifically listed for minor interactions with significant clinical impact.
Monitoring
Baseline Monitoring
Rationale: To establish baseline lung function and assess disease severity (asthma/COPD).
Timing: Prior to initiation of therapy.
Rationale: To check for signs of oral candidiasis (thrush) and instruct on proper rinsing.
Timing: Prior to initiation.
Rationale: Consider for patients transitioning from systemic corticosteroids or those at risk for adrenal suppression.
Timing: Prior to initiation if indicated.
Routine Monitoring
Frequency: Periodically (e.g., every 6-12 months or as clinically indicated for asthma/COPD control).
Target: Improvement from baseline, maintenance of optimal lung function.
Action Threshold: Significant decline or lack of improvement may indicate inadequate control or need for re-evaluation.
Frequency: Regularly (e.g., at each follow-up visit, patient self-monitoring daily).
Target: Minimal symptoms, infrequent rescue inhaler use, no exacerbations.
Action Threshold: Increased symptoms, increased rescue inhaler use, or exacerbations indicate poor control and require treatment adjustment.
Frequency: Regularly (e.g., at each follow-up visit).
Target: Absence of white patches or inflammation.
Action Threshold: Presence of oral candidiasis requires antifungal treatment and reinforcement of rinsing technique.
Frequency: Regularly (e.g., every 3-6 months).
Target: Normal growth velocity for age.
Action Threshold: Growth retardation may indicate systemic corticosteroid effects and require re-evaluation of therapy.
Frequency: Periodically, especially in patients at risk for hypokalemia or hyperglycemia (e.g., concomitant diuretics, diabetes).
Target: Normal ranges.
Action Threshold: Significant deviations may require intervention or dose adjustment.
Frequency: Consider for patients at high risk for osteoporosis with long-term ICS use.
Target: Maintain healthy BMD.
Action Threshold: Significant bone loss may require intervention.
Symptom Monitoring
- Worsening asthma/COPD symptoms (e.g., increased shortness of breath, wheezing, cough)
- Increased need for rescue inhaler (e.g., albuterol)
- Signs of oral candidiasis (white patches in mouth/throat)
- Signs of systemic corticosteroid effects (e.g., easy bruising, moon face, weight gain, adrenal insufficiency symptoms like fatigue, nausea, dizziness)
- Cardiovascular symptoms (e.g., palpitations, chest pain, tremor, nervousness)
- Paradoxical bronchospasm (immediate worsening of breathing after inhalation)
Special Patient Groups
Pregnancy
Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. There are no adequate and well-controlled studies of Wixela Inhub in pregnant women. Animal studies have shown teratogenic effects with fluticasone and salmeterol at high doses. Poorly controlled asthma in pregnancy poses risks to both mother and fetus.
Trimester-Specific Risks:
Lactation
Consider the developmental and health benefits of breastfeeding along with the mother's clinical need for Wixela Inhub and any potential adverse effects on the breastfed infant from the drug or from the underlying maternal condition. Fluticasone and salmeterol are excreted in animal milk; it is unknown if they are excreted in human milk. Systemic exposure to both drugs is low following inhalation.
Pediatric Use
Approved for asthma in children aged 4 years and older. Monitor growth velocity in pediatric patients receiving ICS, as long-term use may affect growth. The lowest effective dose should be used. Safety and efficacy in children younger than 4 years have not been established. Not indicated for COPD in pediatric patients.
Geriatric Use
No overall differences in safety or effectiveness have been observed between elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Dosage adjustment is generally not required based on age alone. Monitor for age-related comorbidities (e.g., cardiovascular disease, osteoporosis, diabetes) that may be affected by the drug.
Clinical Information
Clinical Pearls
- Wixela Inhub is a maintenance medication and should be used regularly, even when symptoms are absent. It is NOT a rescue inhaler.
- Always instruct patients to rinse their mouth thoroughly with water and spit it out after each dose to minimize the risk of oral candidiasis (thrush) and systemic absorption of fluticasone.
- Patients should be educated on the proper use of the Diskus device, including loading the dose and inhaling correctly.
- Paradoxical bronchospasm is a rare but serious side effect; patients should be instructed to use their rescue inhaler immediately and seek medical attention if it occurs.
- Regular monitoring of asthma/COPD control (e.g., symptom diaries, peak flow readings, frequency of rescue inhaler use) is crucial.
- Be aware of potential drug interactions, especially with strong CYP3A4 inhibitors, which can significantly increase systemic exposure to both components.
- In COPD patients, ICS/LABA combinations have been associated with an increased risk of pneumonia; monitor for signs and symptoms.
Alternative Therapies
- Inhaled Corticosteroids (ICS) monotherapy (e.g., fluticasone propionate, budesonide, mometasone) for asthma.
- Long-Acting Beta2-Adrenergic Agonists (LABA) monotherapy (e.g., salmeterol, formoterol, arformoterol) - generally not recommended for asthma due to black box warning, but used in COPD.
- Long-Acting Muscarinic Antagonists (LAMA) monotherapy (e.g., tiotropium, umeclidinium) for COPD.
- Short-Acting Beta2-Adrenergic Agonists (SABA) for rescue (e.g., albuterol, levalbuterol).
- Oral corticosteroids (for severe exacerbations or refractory disease).
- Leukotriene receptor antagonists (e.g., montelukast) for asthma.
- Phosphodiesterase-4 inhibitors (e.g., roflumilast) for severe COPD.
- Biologics (e.g., omalizumab, mepolizumab, benralizumab, dupilumab) for severe asthma.
