Hello You are an old case of ASTHMA hence taking seretide & monteleukast as both these drugs are antihistamine and decreases allergy . Since you are an old asthmatic so I will try to reply in details . Asthma , airways hyperresponsiveness that is secondary to inflammatory airways disease that results in recurrent or chronic episodes of wheeze, shortness of breath, chest tightness and cough particularly in the night or early in the morning. Causative or predisposing factors responsible for asthma are , dust , mite , pollen , molds , pests ( cockroaches ) pets in house , hay fodder, sudden increase or decrease of temperature , humidity . So if possible avoid these factors. When such asthmatic patient visit my clinic I prescribe them to take Monteleukast + BAMBUTEROL tablet once or twice in day till complete relief in symptoms . Hot coffee and steam inhalation also provide relief. Since you are already asthmatic patient so TERTIARY PREVENTION is important in your case. Wash all bed covers in the hot cycle ( 60 degree C). Treat carpets with tannic acid . clean upholstered furniture thoroughly . Keep dust accumulating objects in dustbin. Install air conditioner or dehumidifier . Also avoidance is necessary for an asthmatic patient . Hope this will help you.
