Hi Sir. My father was taking Gluconorm G1 500 and single dose was sufficient to bring his diabetes under control. One of the doctors suggested a replacement to this medicine due to its side effects on creatine levels. At moment he is taking reclide xr 60 and 1 more in the afternoon. With this replacement his sugar levels are varying / increasing. The old tablet was considered suitable I.e. G1. Now the query is whether G1 impacts the creatine levels to be considered for alternate medicines?
