My dad is diabetes patient. He use to go many times for urine in night time.(frequent urination more than 4 times). Not able to sleep due to this problem. We consulted the doctor. He suggested silodal D8 combipack for 45 days course. He had 5 tablets till now. Still no effect. Please suggest me any other tablets. He is 70 year old. Sugar level is normal. He is having tablets trilosar 12.5, ecosprin gold 10, for heart related (he had angioplasty operation 4 year back) lodus 5, glylup M, for sugar control. Pls suggest tablets that control frequent urination in night.
