A cough can sometimes change from wet with mucus to a dry, irritating one, especially at night or early morning when the airways are still healing after an infection. Even though the phlegm reduces, the throat and bronchial tubes can stay sensitive for a few days, which is why coughing may continue for long stretches, mainly while lying down or waking up. Since Kufril LS is mainly useful when there is mucus, it may not fully control this dry, tickly cough phase. In this stage, simple care like warm water, steam inhalation, avoiding cold air or dust, and sleeping with the head a little raised can make a difference and reduce irritation. If the cough keeps disturbing sleep or doesn't settle in a few days, a doctor may need to check whether it has turned into a post-infection cough, allergy, or airway sensitivity and may adjust the medicine accordingly. It's better not to keep switching syrups on your own, especially if there is wheezing, chest tightness, fever, or breathlessness. If symptoms drag on or worsen, a proper check-up is important to rule out ongoing infection or lung irritation.
