You will receive instructions from your doctor regarding the necessary preparation. Most patients will be allowed to eat normally the day before the exam. Patients will be instructed not to take anything by mouth after 7 pm the night before the exam. It is very important to follow the instructions given to you by your doctor. There will also be additional instructions regarding your medications. In most cases, your medications will be continued as usual a few hours after the capsule is ingested. However, in certain circumstances, especially in patients on blood thinners (i.e., coumadin, warfarin, Plavix, aspirin, anti-inflammatories) and in diabetics, special instructions will be given.
