Dry cough in allergic asthma or bronchitis that continues even after using Levolin and Ambrodil usually means the airways are still inflamed and sensitive, not fully controlled yet. These medicines mainly help with opening the airways and clearing mucus, but they don't always settle the underlying irritation that causes a persistent dry cough. Because of this, symptoms can linger for days or even weeks, especially if triggers like dust, smoke, cold air, or weather change are still present around you. In many people, relying only on reliever medicines gives short-term relief but not full control, so the cough keeps coming back. In such situations, doctors often reassess the treatment and may add or adjust a controller inhaler that works on reducing airway inflammation, which is the main issue in allergic asthma. It is also important to check inhaler technique because incorrect use can reduce effectiveness. Since you already have a known history of asthma and bronchitis, it is better not to keep self-adjusting medicines and instead get a review so your treatment can be properly balanced and symptoms controlled more steadily without repeated flare-ups.
