Seek medical advice if your asthma symptoms worsen, if your rescue inhaler becomes less effective, or if you experience severe side effects such as chest pain, rapid heartbeat, or worsening breathing problems.
Dulera can interact with several medications. Here are some Dulera interactions you should know about:
| Drug / Drug Class | Drug Examples | Possible Interaction |
|---|---|---|
| Strong CYP3A4 inhibitors | Ketoconazole, Itraconazole, Ritonavir, Clarithromycin | May increase systemic exposure to mometasone, raising the risk of corticosteroid side effects such as adrenal suppression and Cushing‑like effects. |
| Beta‑blockers | Propranolol, Atenolol, Metoprolol | May block the bronchodilator effect of formoterol and can trigger bronchospasm in asthma patients. |
| Diuretics (non‑potassium sparing) | Furosemide, Hydrochlorothiazide | May increase the risk of hypokalemia and ECG changes when used with beta‑agonists like formoterol. |
| Tricyclic antidepressants / MAO inhibitors | Amitriptyline, Phenelzine, Tranylcypromine | May potentiate the cardiovascular effects of beta‑agonists, increasing the risk of arrhythmias and hypertension. |
| Other LABA medications | Salmeterol, Indacaterol, Olodaterol | Concomitant use may increase the risk of overdose and serious asthma‑related events; it should generally be avoided. |
| Systemic corticosteroids | Prednisone, Dexamethasone | May increase overall corticosteroid exposure, raising the risk of adrenal suppression and systemic steroid effects |
