Hello and thanks for your enquiry,

Many people take senna regularly and some long term without issue. As with all medicines, they should be reviewed by a doctor anyway on a regular basis. You can also seek advice on laxatives from your local pharmacist.

There is NHS information on constipation and how to avoid it. If you wish to read more about risk factors for bowel cancer then Bowel Cancer UK have useful information.

I hope this helps,

Best wishes,

Vanda
