My mother is having diebities since last 10 years at an average level of 200 to 280 (fasting) now our family doctor had suggest to stat give insulin (lantus soloster) now the sugar level is from 100 to 140. Now I wanted to know that does this insulin has any side effects or not. And if yes what are they. And for how long will I have to continue this insulin treatments, is there any chances that insulin will be stop in future. Currently my mother's age is 50 years and also having asthama problem and unit of insulin is given from 8unit to 18 units. (2 unit is increased as sugar level rises above 110, and accordingly decrease if sugar level comes below 110 (fasting)). Is it true that once you stat giving insulin, it will have to continue whole life, it can't be stop, as other tablets will now be less effective. My mother is taking tablets 1) glix m. 3 times a day 2) pioz 15. Once daily 3) telecast a once daily 4) faracort 400. Twice daily 5) tiova. Twice daily please help me, I am confused.
