Duova Inhaler 200 mdi is a respiratory medication primarily used to treat and prevent asthma and chronic obstructive pulmonary diseases (COPD) like bronchitis (inflammation of the lining of your bronchial tubes) and emphysema (shortness of breath). Asthma is a chronic (long-term) respiratory condition in which airways narrow, swell and produce extra mucus, leading to difficulty breathing. COPD is a group of lung diseases that causes obstructed airflow from the lungs.

Duova Inhaler 200 mdi is a combination of Formoterol (bronchodilator) and Tiotropium (anticholinergic). Formoterol relaxes the muscles in the airways and increases airflow to the lungs. Formoterol makes breathing easier by widening the airways. Tiotropium works by blocking the receptors for acetylcholine released in the cholinergic nerve endings in the airways. Duova Inhaler 200 mdi relaxes and widens the airway's openings, making it easier for the air to get in and out of the lungs. Thereby, it helps to prevent asthma attacks.

Your doctor will advise on how often you need to use Duova Inhaler 200 mdi based on your medical condition. The common side effects of Duova Inhaler 200 mdi include nausea, vomiting, respiratory tract infection, headache, sore throat, cough, bone, muscle or joint pain, increased heart rate, chills, tiredness, and noisy breathing. Most of these side effects of Duova Inhaler 200 mdi 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 Inhaler 200 mdi to treat sudden severe symptoms of asthma or as a rescue inhaler. Please check with your doctor if you are pregnant, breastfeeding, or taking other prescribed or non-prescribed medicines. Brief your medical history 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.

Duova Inhaler 200 mdi is used to treat and prevent respiratory disorders like asthma and chronic obstructive pulmonary disease (COPD). Duova Inhaler 200 mdi improves pulmonary function and effectively treats and prevents the worsening of emphysema (shortness of breath) and chronic bronchitis (inflammation of the lining of your bronchial tubes). Duova Inhaler 200 mdi contains Formoterol (bronchodilator) and Tiotropium (anticholinergic). Formoterol is a long-acting β₂ agonist and bronchodilator. It relaxes the muscles in the airways and increases airflow to the lungs. It makes breathing easier by widening the airways. Tiotropium works by blocking the receptors for acetylcholine which are released in the cholinergic nerve endings in the airways. 

• Nausea
• Vomiting
• Respiratory tract infection
• Headache
• Sore throat
• Cough
• Dry mouth
• Constipation

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 Inhaler 200 mdi 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 Inhaler 200 mdi. Duova Inhaler 200 mdi 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. Duova Inhaler 200 mdi is not recommended for children below five years of age.

Drug-Drug Interactions: Duova Inhaler 200 mdi may interact with fluid retention drugs (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: Limit alcohol intake since it may cause a rise in blood pressure leading to heart diseases.

Drug-Disease Interactions: Inform your doctor if you have any allergic reactions to medicines, 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.

• BECLOMETASONE
• MOMETASONE
• BUDESONIDE
• IPRATROPIUM
• SALMETEROL
• VILANTEROL
• ALBUTEROL
• METOPROLOL
• SOTALOL

• 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 Inhaler 200 mdi can cause low potassium levels in the blood (hypokalaemia).
• Regularly monitor your blood sugar levels while using Duova Inhaler 200 mdi since bronchodilators like Formoterol can cause low blood glucose levels.
• Consult your diabetologist if you have diabetes before using Duova Inhaler 200 mdi so that your insulin or other diabetic medication can be adjusted accordingly to maintain your blood sugar levels.

Asthma: It is a breathing problem in which airways narrow, swell and produce extra mucus, leading to difficulty breathing.

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.
