A cough lasting for about a week that is not improving with Piriton and Levolin Plus is often seen when the cause is not just a simple allergy, but ongoing airway irritation after a viral infection, post-nasal drip from the nose or sinuses, or sometimes mild bronchial inflammation. These medicines may give partial relief if allergy is involved, but if mucus or throat irritation is the main trigger, the cough can continue despite treatment. In some cases, acid reflux, dust exposure, or weather changes can also keep the throat sensitive and prolong the cough cycle. At this stage, recovery usually depends more on supportive care. Warm fluids, steam inhalation, and good hydration help loosen mucus and soothe the airways. Avoid cold drinks, smoke, perfumes, and dusty environments as they can worsen coughing. Resting the voice and sleeping with the head slightly elevated can also reduce nighttime irritation. If the cough continues beyond 10?14 days, or if there is wheezing, chest tightness, fever, or breathlessness, it is important to get examined to check for an asthma flare, sinus-related drip, or chest infection that may need different treatment.
