What To Do For Allergic Cough At Old Age?

My mother, 85 years old developed allergic cough about a year back and we showed her to two or specialists who had prescrobed mouth spray like 'simply one' and formaldyne or so. We have been giveing her all through the period and effect was almost nil. over above we had given her lozengers and cough syrups to subside the cough. The side effect was being a diabetic her blood sugar shot up and she is under pills. We had now stopped all sugar base cough syrups and lozengers and give only sugar free cough syrup. As a result of high blood sugar 2++ (PP) she is very weak and we started giving eldervit 12 injection as prescribed by doctor once a week. First injection was given last sunday and five more injections to continue in the weeks to come. Her weakness still continues. We are vegetarians and her intake is very low. How to sort out the problems. Grateful if you could kindly send in your advice. My email: nagups @ WWW.WWWW.WW
