You can take your scheduled medications other than blood thinners on the day of the colonoscopy. It is important that you take heart and hypertension medications according to your normal schedule, and before the procedure is fine (DO NOT MISS DOSES!). If you have an inhaler, please use it before you come in for the colonoscopy and bring it with you. If you are diabetic, contact the prescriber of your diabetes medications to discuss any changes needed for your medication regimen around the procedure.
