An allergic cough with a runny nose is usually due to sensitivity to dust, cold air, or other triggers, which irritates the airways. Try to avoid triggers, keep your surroundings clean, and use steam and warm fluids to ease symptoms. A doctor may advise suitable allergy medicines to reduce cough and nasal symptoms based on your condition. If it keeps coming back or does not improve, it is better to get checked for proper long-term control.
