Hello Sanjay Your father is 70 years old and an asthmatic patient. When such patient visit with these symptoms I prescribe my patient MONTELUKAST+ ALBUTEROL tablet once or twice in day depending on the condition of patient and severity of symptoms. Usually patients responds very well and don't require any inhaler. Now about deriphyllin injection (don't gibe Benson as this is very dangerous for prolong use and keep this Chat Doctor. So DERIPHYLLINE is available in 2 ml strength. Take 2 ml in a syringe and introduce in vain (INTRAVENOUS) and insert medicine in the vein very, very slow. 2nd option is intramuscular either in the deltoid (shoulder) or gluteal muscle (hip) . Avoidance for pollen, mold, pests (cockroaches) , hay, fodder, fine dusting powder, sudden fall and rise of temperature, humidity, mite, dust are certain predisposing factor which triggers an asthmatic attack. Air conditioner, hot coffee, steam inhalation also helps. Hope this information will be helpful for your father.
