Inhalers like Seroflo are generally safe for asthma/COPD, but sometimes steroids or bronchodilators can relax the oesophagus slightly, which may contribute to acid reflux (GERD). Other factors like diet, obesity, or lying down after meals can also trigger GERD. You should discuss your symptoms with your doctor, who can suggest ways to manage reflux.

Since you have chest congestion, a severe cough, and breathing difficulty triggered by allergies, and Seroflo is not helping, this could indicate an asthma flare-up or allergic bronchitis. You should see your doctor or pulmonologist for proper evaluation. Meanwhile, avoid exposure to soil or dust, use a mask if needed, and stay hydrated.

For dust allergies that trigger bronchitis, cough, and congestion, treatment usually includes avoiding dust exposure, using antihistamines or anti-allergy nasal sprays, and inhalers or bronchodilators if your airways get tight. Saline nasal washes and steam inhalation can also relieve congestion. It is best to consult an ENT or pulmonologist, who can prescribe the right medicine and check for asthma or chronic bronchitis, rather than self-medicating.
