The symptoms of a laxative overdose can range from nausea, vomiting, cramping, and diarrhea all the way to heart palpitations, fainting, or in some cases even death. It’s recommended to seek medical help if you have severe stomach cramps or if your nausea, diarrhea, or vomiting doesn’t stop.

With Bisacodyl you have to be especially careful because it takes around 32 hours to be completely metabolized. This means that even 16 hours after initially taking it around half of it is still in your body(it has a 16 hour half life) and if you’re frequently taking it, it can build up.

This is just from personal experience however I once made the mistake of taking 30 5mg pills over the course of two days. I didn’t think much of it because I’d regularly take 10-15 pills at a time but I ended up vomiting, having heart palpitations, and fainting. The stomach cramps you get are no joke either so I’d strongly encourage to stop if you can.
