Good product that works well
These work well for constipation. Normally, they take between 30 to 45 minutes to be really effective when I use them. Bisacodyl stimulates the colon muscles, and it's important to wait long enough to give it a chance to work. Although the instructions say the suppositories work in as little as 15 minutes, you probably should plan on waiting at least 20 to 30 minutes after insertion before going to the toilet.
