After Colonoscopy

Following intravenous sedation, up to 24 hours are required for the full effect
of the drugs to wear off. During this period, it is essential that you follow these

On leaving the office, you MUST be accompanied by a responsible adult, who may
either drive you home or accompany you home in a taxi. We strongly advise against
the use of public transportation.

On arrival home, it is common to feel sleepy. You are advised to rest quietly at home
for the balance of the day. Lie flat if you feel dizzy of light-headed. It is normal to
experience some abdominal cramping for 2-3 hours following a colonoscopy. This
is from residual air in the colon in most cases. It is also not unusual to pass a small
amount of blood (a teaspoon or less) in your next one or two bowel movements.

If you have not had a polypectomy, you may resume a normal diet when you return
home unless otherwise instructed by Clinic staff. Please do not go to a restaurant on
the way home. Get home first, and then if you feel well you may begin a normal diet
but eat only lightly for the remainder of the day.

If you have had a polypectomy, you are encouraged to drink clear fluids (non-citrus
juice or non-diet soft drinks) for the remainder of the day, but avoid solids. On the
morning following the polypectomy procedure, if you feel well, you may resume a
normal diet.

Avoid alcohol in any form for 48 hours following sedation. Avoid any drugs that
may affect the nervous system for 24 hours. These would include sedatives,
sleeping pills, etc.
