If you need to take any kind of daily medication that causes constipation, like painkillers, you may well need these.
I have taken them for years to offset the constipating effect of prescription painkillers.
The box does say for temporary use, but having tried other items like Fybogel I am happy to stick with these tablets.
Its a lot easier to swallow a couple of small tablets than Fybogel or Psyllium Husks, which also work but I find unpleasant to take.
My GP prescribed Fybogel for me but as it contains Aspertame, a chemical sweetener I changed to these herbal tablets.
