Wixela Inhub Precautions

Serious side effects have been reported with Wixela Inhub including the following:

  • serious asthma-related events - hospitalizations, intubations, death. Using a long-acting beta agonist without an inhaled corticosteroid is linked to an increased-risk of asthma-related death. However, this medication has both a long-acting beta agonist with an inhaled corticosteroid. 
  • deterioration of disease and acute episodes. This medication should not be started for patients who have rapidly deterioriating or life-threatening asthma or COPD. This has not been studied for patients who have completely uncontrolled asthma or COPD. Serious respiratory events that can be fatal. Patients that increase their use of a rescue inhaler (like albuterol or levalbuterol) may need to be re-evaluated and put on a higher strengh of Wixela Inhub. Wixela Inhub should only be used twice a day. Wixela Inhub also shoud not be used for acute symptom management or rescue therapy for acute episodes of shortness of breath or wheezing. 
  • excessive use of Wixela Inhub and use with other long-acting beta2-agonists. Wixela Inhub should not be used more than recommended or with other medications containing a long -acting beta agonist (salmeterol, formoterol, arformoterol, indacaterol). This can cause an overdose, which can result in problems with the heart or death.
  • local effects of inhaled corticosteroids. Wixela Inhub has been found to cause infections of the mouth and throat. These infections should be treated with antifungal therapy if they occur. Wixhela Inhub may have to be interrupted during this treatment period. Patients should be told to rinse their mouth out after using Wixhela Inhub to reduce the potential for infections.
  • pneumonia. Physicians should carefully watch patients on this medication to look for signs of pneumonia. Lower respiratory tract infections like pneumonia have been seen in patients taking this medication. 
  • immunosuppression. Patients who take medications that suppress the immune system (like corticosteroids) are more prone to infections. Wixhela Inhub should be used with caution for patients with active infections.
  • transferring patients from systemic corticosteroid therapy. Patients who are on active corticosteroids must be carefully transitioned to inhaled corticosteroids. Adrenal insufficiency can cause death in patients who are poorly managed during the change. Patients on 20 mg or more of prednisone are most at risk. Patients with oral steroids should be weaned slowly after changing to Wixela Inhub. A healthcare provider can help provide the dosing for this transition. 
  • hypercorticism and adrenal suppression. Wixela Inhub contains an inhaled corticosteroid. There can be the potential for systemic corticosteroid effects, which can cause adrenal suppression. Patients should watch for signs of adrenal crisis like dehydration or fatigue.
  • drug interactions with strong cytochrome P450 3A4 inhibitors. Increased risk of heart problems or increased steroid concentration can occur with this medication when used with strong P450 3A4 inhibitors. Wixela Inhub should not be used with medications such as ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, ketoconazole, or telithromycin.
  • paradoxical bronchospasm and upper airway symptoms. Wixela Inhub can cause paradoxical bronchospasm (wheezing, harder work of breathing), which can be life-threatening. A bronchodilator like albuterol should be used immediately if this occurs. If this occurs, Wixela Inhub should be stopped and changed to another medication.
  • immediate hypersensitivity reactions. Itching, swelling, or rash can occur with Wixela Inhub. Patients with severe milk protein allergies are most at risk. These patients should not use Wixela Inhub.
  • cardiovascular and central nervous system effects. Wixela Inhub should be used in caution with patients with heart disorders such as high blood pressure or abnormal heart rhythm. Seizures, angina, blood pressure changes, or faster rate rates can occur. Excessive use of this medication can be fatal. 
  • reductions in bone mineral density. Decreases in bone mineral density have been seen with long-term use of products with an inhaled corticosteroid. Patients with risk factors for lower bone mineral content such as prolonged immobilization, family history of osteoporosis, tobacco use, advanced age, or poor nutrition should be monitored. 
  • effect on growth. Inhaled corticoteroids may reduce the rate of growth for younger patients. Pediatric patients receiving Wixela Inhub should be monitored routinely and use the lowest possible dose.
  • glaucoma and cataracts. Long-term use of inhaled corticosteroids can increase pressure in the eye and cause cataracts. Wixela Inhub should be used in the lowest possible dose to minimize this risk.
  • eosinophilic conditions and Churg-Strauss Syndrome. In rare cases, patients on inhaled corticosteroids can see white blood cell complications. Eosinophilic conditions like a rash, worsening lung symptoms, heart issues, or nerve pain should be monitored. 
  • coexisting conditions. Wixela Inhub should be used cautiously in patients with convulsive disorders. Medications like Wixela Inhub have been found to exacerbate diabetes and ketoacidosis when injected.
  • hypokalemia and hyperglycemia. Beta agonists can cause a significant decrease in potassium in some patients. Lowered blood glucose can also be observed in patients using this medication.
