Colonoscopy prep reminders: every step at the right time

Few people look forward to a colonoscopy, and most who have had one will tell you the procedure itself is the easy part. The preparation is what takes effort. For several days beforehand you're following a sheet of instructions with dates, times and rules: what to stop eating, when to switch to clear fluids, when to take each dose of the bowel preparation, when to stop drinking altogether.

Get the timing wrong and the bowel may not be clear enough for the doctor to see properly. In some cases that means the procedure has to be repeated. So it's worth treating the prep schedule the way you'd treat an early flight: plan it, write it down, and set reminders for every step.

One important note before anything else: your clinic's instructions are the ones that count. Prep regimens differ between hospitals, products and patients. Everything below is about organising and remembering the instructions you've been given, not replacing them. If anything is unclear, call the clinic or check with your doctor.

Why the prep schedule is easy to get wrong

The instructions often arrive weeks in advance, on paper, and then sit in a drawer. By the time the prep starts, you're working from memory.

The schedule also has a lot of moving parts:

• Medication changes some days before, which your doctor may ask you to make, for example with blood thinners, diabetes medication or iron tablets. Never change medication without clear instructions from your own doctor.
• Diet changes a few days before, often a low-fibre diet.
• Clear fluids only from a set time the day before.
• The prep doses themselves, often split into two, with the second dose sometimes very early in the morning.
• A cut-off time after which you shouldn't eat or drink anything at all.
• Transport, because you'll usually need someone to take you home if you have sedation.

Each of these has its own time. That's a lot to hold in your head while also feeling hungry and uncomfortable.

Turn the instruction sheet into a timeline

As soon as you have your appointment date, sit down with the instruction sheet and a calendar.

1. Write the appointment date and arrival time at the top.
2. Work backwards through each instruction. For each one, write the actual date and clock time. "Three days before" becomes "Monday". "Four hours before your appointment" becomes "6:30am Thursday".
3. Highlight anything you're unsure about and phone the clinic to check. Better to ask now than guess at 5am on the day.
4. Check your prep kit. Make sure you have the prep product your clinic prescribed, and any clear fluids you plan to drink.
5. Book your lift home. Confirm with a friend or family member, and set a reminder for them too.

Once you've got a written timeline, turning each line into a reminder is straightforward.

Sample prep reminders

Here's the kind of wording that works. Adjust every time and step to match your own instructions.

• A week before: "Colonoscopy next Thursday. Check medication instructions from the clinic and buy prep supplies."
• Diet change day: "Low-fibre diet starts today. See the list on the fridge."
• Clear fluids start: "Clear fluids only from now. No solid food until after the procedure."
• First prep dose: "Time for the first dose of bowel prep. Mix as the instructions say and drink it over the time given."
• Second prep dose: "Second prep dose now. Set out the rest of your clear fluids."
• Stop drinking: "Nothing more to eat or drink from now, as per the clinic's instructions."
• Leave for the appointment: "Leave for the hospital now. Bring the instruction letter, ID and your medication list."
• For your driver: "Collect Mum from the endoscopy unit. She'll message when she's ready."

Specific wording matters on a day when you're tired and hungry. "Second dose now" is more useful than "prep".

The early-morning dose

Many split-dose preparations involve a second dose in the early hours of the morning. This is where alarms fail: you're asleep, you're exhausted, and a quiet phone chime is easy to sleep through.

Put this reminder somewhere you'll definitely hear it. Keep the phone by the bed with the sound on, and consider a backup, such as a second alarm or someone in the house who knows the time too.

Checklist for the days before

• Instruction sheet read and questions answered by the clinic
• Every step written as a real date and clock time
• Medication changes confirmed with your doctor
• Prep kit and clear fluids at home
• Lift home arranged and confirmed
• Reminders set for each step, including the early-morning dose
• Bag packed: letter, ID, medication list, something warm to wear

After the procedure

The reminders don't need to stop when you leave the hospital. You may have been told when to restart any medication you paused, or when to expect results. Add those as reminders too, before you forget what the nurse said.

How ReminderIt helps

ReminderIt calls your phone at the times you choose and reads your reminder aloud in a warm, natural voice, then sends the same reminder on WhatsApp with Done and Snooze buttons. For a timed routine like bowel prep, a ringing phone is much harder to sleep through or ignore than a silent notification. If you miss the call, the WhatsApp message is there, and ReminderIt tries the call once more about five minutes later.

You can set every step by chatting on WhatsApp in plain words:

• "Remind me on Wednesday at 4pm to switch to clear fluids only."
• "Remind me on Wednesday at 6pm to take the first dose of bowel prep."
• "Remind me on Thursday at 5am to take the second dose of bowel prep."

Or send a photo of your instruction sheet or appointment letter, and ReminderIt will turn it into reminders for you to check and confirm. Always compare them against the sheet before you rely on them.

Because a 5am reminder looks a lot like an AM/PM mistake, it's worth knowing about the optional "ask before night-time calls" setting, which checks with you before any call between midnight and 6 AM. And if a parent or partner is the one doing the prep, you can add them as one of your people, so the reminders ring their phone. They accept once, and if they miss a call you can get an alert.
