Laxopeg for indigestion and motion probl

Hi doctor's, I have started developing a problem with my digestion with no motion since last 3 weeks and after consulting doctor,he suggested laxopeg granules morning and night for 30 days. My question is,Is it safe to use laxopeg for long duration and he also suggested to stop morning dose if my situations gets better. And he  also told that he will plan for a colonoscopy after a month if there is no improvement. I'm very much worried now as this is becoming very complicated by looking at colonoscopy as a option. I have been using laxopeg from last 4 days and noticed significant improvement in my digestion and bowel movement. Please suggest my future options by looking at my medication and treatment.thank you.
