如何為腸鏡檢查做準備?

在我們的藥房，人們經常詢問我們有關結腸鏡檢查 (colonoscopy) 前需準備的藥物。我們可以幫助你選擇恰當的藥物并指導如何正確用藥，讓你在結腸檢查前做好充分準備。

在安大略省，建議50歲及以上的人們去做 大腸癌篩查。對於大多數人來說，可以每隔2年重複一次，在家做一個簡單的測試稱為糞便隱血試驗（FOBT）。然而，對於因為家庭成員有患大腸癌的高風險的人, 建議使用結腸鏡檢查。FOBT結果異常的人也會建議做結腸鏡檢查。

做結腸鏡檢查是非常重要的，因為如果結腸癌在早期發現，它具有90％被治愈的可能性。

這個檢查是在醫院做的，醫生將檢查結腸，採取活組織切片檢查，並切除任何異常生長的部分。該過程持續一個半小時，你可能需要服用鎮靜藥物，讓你在手術過程中感覺更舒適。

結腸鏡檢查前的準備：

結腸鏡檢查前，病人會收到說明告知在結腸檢查日期之前的2天內必須做的準備。如果您沒有收到任何信息，請務必聯繫診所，因為你的診所或醫生可能對結腸鏡檢查的準備有他們自己的具體建議。

一般情況下，你需要清空你的結腸，因為任何在結腸內的殘留物都可能會在檢查中掩蓋了清晰的視野。結腸鏡檢查之前的一天，必須遵循特殊的飲食。通常情況下，你不能吃固體食物。一般是允許飲清澈的液體，如清水，茶或清湯，但是，你不能午夜後吃或者喝任何東西。

您還需要服用瀉藥，所以建議您留在家裡，因為你將要經常使用的衛生間。用於結腸鏡檢查的藥物可以非處方藥購買，但是，對於65歲及以上患者，安大略省藥品福利（ODB）會支付這些藥物的費用，但需要醫生的處方。如果你還沒有處方，我們可以幫你聯繫你的醫生把你的處方傳真給我們。

一般來說，你將在手術前2天睡前口服通便劑（Dulcolax）2片，然後在檢查的前一天，在白天服用瀉藥粉沖劑（Odan PURG）2次，相距約4小時。

何時服用瀉藥粉沖劑取決於第二天的檢查時間。例如，如果檢查被安排在上午，那麼兩袋瀉藥粉沖劑的將在檢查前一天服用。但是，如果檢查定於下午，您就要在檢查前一天服用一包瀉藥粉，檢查當天早上再服一包。你必須遵照指引的時間來服用這些藥物，這是非常重要的。

小袋里的粉末具有潤腸通便的作用，服用前要加冷水混合。建議飲用前用5盎司（150ml）的冷水混合，攪拌均勻，不要用太熱的水混合粉末因為混合物將變得非常熱，很難喝。

一定要告訴你的醫生你目前正在服用哪些藥物，特別是服用鐵補充劑或稀血的藥物（如阿司匹林，氯吡格雷，華法林，Pradax，Xarelto等。

在美健藥房，我們可以幫你準備你的用藥報告，方便您帶給您的醫生，讓他們可以看到你正在服用的藥物的完整清單。

醫生可能需要暫時調整劑量或停止某些藥物，以避免結腸鏡檢查中出現任何問題。

How to prepare for a colonoscopy?

At the pharmacy, we often see patients looking for the medications to prepare for a colonoscopy. We can help by selecting the right medications for you and clarifying the dosing instructions to get you ready for the procedure.

In Ontario, Colorectal cancer screening is recommended for people 50 years and older. For most people, a simple at home test called the Fecal Occult Blood Test (FOBT) can be done every 2 years. However, for people at increased risk because of a family member with a diagnosis of colorectal cancer, a colonoscopy is recommended.  A colonoscopy can also be recommended as a follow-up test for an abnormal FOBT result.

It is important to do the colonoscopy because if colon cancer is caught early, it has a 90% chance of being cured.  It is a procedure that is done at the hospital, where a doctor will examine the colon, take biopsies and remove any abnormal growths. The procedure lasts about half an hour and you can receive a sedative medication on site to make you more comfortable during the procedure.

Preparing for a colonoscopy:

To prepare for a colonoscopy, patients will likely receive an instruction sheet that explains what they have to do during the 2 days prior to the procedure date. If you have not received any information, be sure to contact the clinic for the details because your clinic or your doctor may have their own specific recommendations for the preparation of a colonoscopy.

In general, you will be asked to empty your colon because any residue in your colon may obscure the view during the procedure. You will be instructed to follow a special diet the day before the exam. Usually, you will not be allowed to eat solid food the day before the procedure. Clear liquids such as plain water, tea or clear broth are generally allowed, however, you may not be able to eat or drink anything after midnight before the procedure.

You will also be instructed to take laxatives, so it is recommended that you stay home during the day prior to the procedure since you will be using the bathroom frequently.

The medications used for colonoscopy preparation can be purchase without a prescription, however, for patients 65 years and older, the Ontario drug benefit (ODB) will cover the cost of these medications with a prescription from your doctor. If you do not have a prescription yet, we can ask your doctor to send us a prescription.

In general, you will be instructed to take an oral tablet laxative (Dulcolax or Bisacodyl) 2 tablets at bedtime, 2 days before the procedure. And then on the day before the procedure, you will be asked to use a powder sachet laxative (Pico-Salax or Purg Odan) 2 times during the day, about 4 hours apart.

The timing for taking the powder sachet laxative depends on the time of the procedure scheduled on the next day. For instance, if the procedure is scheduled for the morning, then both packets of powder sachets are used on the day BEFORE the procedure.

However, if the procedure is scheduled for the afternoon, you may be asked to use one packet of the powder sachet laxative on the day before the procedure and one packet on the morning of the procedure date.

The time that you have to take these medications is usually specified in the instruction sheet, it is very important for you to follow the given instructions.

The powder sachet laxative has to be mixed in water prior to taking it. It is recommended to mix the powder in 5 oz (150ml) of cold water and stir it frequently prior to drinking it. Do not use hot water
to mix the powder because the mixture will get very hot and difficult to drink.

Be sure to tell your doctor about the medications that you are currently taking, especially if taking supplements that contains iron or medications that thins your blood (i.e. Aspirin, Plavix, Coumadin - warfarin, Pradax, Xarelto, etc.).

At Custom Care Pharmacy, we can prepare a medication profile report for you to bring to your doctor so that they can see a complete list of medications that you are currently taking. 

The doctor may need to adjust your dosage or stop certain medications temporarily to avoid any problems during the colonoscopy. If you have any questions about the medications that you need to purchase for your upcoming colonoscopy, please feel free to contact us at Custom Care Pharmacy 905-305-0111
