<s>[INST] Do allergies cause coughing? I had a bad cough all winter, and it went away for a couple months when the weather got warmer. It just started again since the weather has gotten very hot (90 degrees) and rainy. Is there a cough medicine for coughs due to allergies? [/INST] Thanks for your question on Chat Doctor. I can understand your concern. You are having seasonal bronchitis. It is commonly seen in winters and monsoons. So you should take combination of antihistamine (levocetrizine or fexofenadine) and anti-allergic (montelukast) 1 week before starting of winter and stop once winter is over. This combination should be taken once a day at night before going to sleep. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
