Preparing for a colonoscopy means clearing your bowel so your doctor can see clearly during the procedure. The Boardwalk Pharmacy stocks the two most-prescribed bowel preparation options in Canada — Peglyte and PICO-SALAX — and our pharmacists can help you understand the difference, the schedule, and what to expect at no cost.
What we carry
-
Peglyte (polyethylene glycol) — a high-volume, fruit-flavoured powder mixed with water. The standard choice for many gastroenterologists. View Peglyte →
-
PICO-SALAX (sodium picosulfate) — a low-volume, orange-flavoured sachet option. Easier for patients who struggle with the larger Peglyte volume. View PICO-SALAX →
Which one should I use?
Your doctor’s instructions take precedence — always follow what’s on your colonoscopy prep sheet. If you have flexibility, the choice often comes down to volume tolerance: Peglyte requires drinking 2–4 litres of solution, while PICO-SALAX needs only a few small glasses of mixed sachets. Both are equally effective when used as directed. Our pharmacists are happy to talk you through it.

Frequently asked questions
Where can I buy colonoscopy prep in Kitchener-Waterloo?
The Boardwalk Pharmacy stocks both Peglyte and PICO-SALAX — Canada’s two most-prescribed bowel preparations. Order online for free local delivery, or pick up in-store at 430 The Boardwalk, Suite 102, Waterloo.
How long does colonoscopy prep take?
Most bowel preps start the day before your colonoscopy and continue into the morning of the procedure. The exact schedule depends on the product (Peglyte takes longer to drink than PICO-SALAX) and your doctor’s specific instructions. Plan to stay home and near a bathroom once you start.
Can I take my regular medications during bowel prep?
Most medications can continue, but some — especially blood thinners, diabetes medications, and iron supplements — may need to be paused or adjusted. Bring your medication list to us or call (519) 578-3000 before your prep day and a pharmacist will go through it with you.
