I have been suffering from cough and cold for more than 2 months. On first occasion, I was given Mucinac 600 tablets twice daily for 4 weeks and Montair FX ,1 tab at night. It worked good and I was relieved. However, after a gap of 15 days, it relapsed. And this time, it is dry cough all along. Coughing increases at night, at midnight and again at the dawn. Mucinac and Montair FX failed this time and I am scared that something ominous has cropped up. Last time doctor advised chest x-ray, CT Scan of lungs and PFT. The outcome of the tests was not that much worrying. Now how to negotiate this dry cough which has become a nightmare for me. Due to Rheumatoid Arthritis I am taking medicine of HCQS 200-1 tab at night, Defza 6x2 tabs in the morning, Sazo 1g each morning & night, Shelcal-HD 1 tab at night, Folvite-5 weekly twice, folitrax-10 weekly once day and night (same day), Telma H 80 for pressure in the morning and Cetapin XR 1000 mg for sugar at night. Presently, Sugar & pressure both under control. Please advise me to get rid of this dry cough. Regards, S. Hazra, Kolkata.
