Duova Multihaler is a respiratory medication primarily used to treat chronic obstructive pulmonary diseases (COPD) like bronchitis (inflammation of the lining of your bronchial tubes) and emphysema (shortness of breath). It may also be used to treat asthma. COPD is a group of lung diseases that causes obstructed airflow from the lungs.

Duova Multihaler contains Formoterol (bronchodilator) and Tiotropium (anticholinergic). Duova Multihaler works by relaxing the muscles in the airways, thereby improving breathing and reducing symptoms such as wheezing, coughing, and shortness of breath.

The common side effects of Duova Multihaler include headache, dizziness, dry mouth, nausea, sore throat, and hoarseness. Most of these side effects of Duova Multihaler do not require medical attention and gradually resolve over time. However, if the side effects are persistent, reach out to your doctor.

Do not use Duova Multihaler to treat sudden severe symptoms or as a rescue inhaler. Please check with your doctor if you are pregnant, breastfeeding, or taking other prescribed or non-prescribed medicines. Keep the doctor informed about your health condition and medications to rule out any side effects/interactions.

Do not use Duova Multihaler if you are allergic to any of its components. Inform the doctor if you have heart, liver, or kidney diseases, high blood pressure, hypokalaemia (low potassium levels in the blood), aneurysm (swelling of an artery), pheochromocytoma (adrenal gland tumour), hyperadrenocorticism (high levels of cortisol), eye disorders like cataract and glaucoma, chickenpox or measles, immune system problem, seizure (fits), osteoporosis (weak and brittle bones) or diabetes. Special precautions should be taken in patients with a fungal, bacterial, parasitic, or viral infection and tuberculosis since nasal or inhaled corticosteroids can cause secondary infections. Duova Multihaler can cause a rise in blood glucose levels. Hence, monitor your blood glucose levels regularly and inform your doctor if you already have diabetes before using Duova Multihaler. Duova Multihaler may affect the unborn baby during pregnancy. Please let your doctor know if you plan to become pregnant or are already pregnant or if you are a lactating mother.

Drug-Drug Interactions: Inform the doctor if you are taking diuretics (furosemide), corticosteroids (budesonide, mometasone, beclomethasone), bronchodilators (vilanterol, salmeterol, albuterol), respiratory drugs (ipratropium), drugs treating irregular heartbeat (sotalol), and blood pressure medicines (metoprolol).

Drug-Food Interactions: No interactions found.

Drug-Disease Interactions: Inform the doctor if you have heart, liver, kidney diseases, high blood pressure, hypokalaemia (low potassium levels in the blood), aneurysm (swelling of an artery), pheochromocytoma (adrenal gland tumour), hyperadrenocorticism (high levels of cortisol), eye disorders like cataract and glaucoma, chickenpox or measles, immune system problem, seizure (fits), osteoporosis (weak and brittle bones) or diabetes.

• Know your triggers like allergens, such as pollen, dust, and food items that make your asthma severe.

• Quit smoking and avoid passive smoking. Smoking also reduces the effectiveness of the medicine.

• Eat a healthy diet and exercise regularly to strengthen your breathing muscles and boost your immune system.

• Learning breathing exercises will help you move more air in and out of your lungs.

• It is advised to undergo a blood examination to keep a check on your potassium levels since Duova Multihaler can cause low potassium levels in the blood (hypokalaemia).

• Regularly monitor your blood sugar levels while using Duova Multihaler since bronchodilators like Formoterol can cause low blood glucose levels.

• Consult your diabetologist if you have diabetes before using Duova Multihaler so that your insulin or other diabetic medication can be adjusted accordingly to maintain your blood sugar levels.

Chronic obstructive pulmonary disease (COPD): It is a group of lung diseases that block airflow and make breathing difficult. The most common COPD is emphysema and chronic bronchitis.

Emphysema: It is a lung condition that causes shortness of breath.

Chronic Bronchitis: A lung disease associated with inflammation of the lining of bronchial tubes, which carry air to and from the lungs.
