Talk to your doctor if you are still constipated after 3 days. They may be able to suggest a different medicine.
It’s not recommended to take Senokot for more than 1 week. Taking senna for longer can lead to diarrhoea. Stop taking it if you get diarrhoea.
It can also cause an electrolyte imbalance, where levels of substances like sodium, potassium and magnesium in your body get too high or too low. A severe electrolyte imbalance can cause serious health problems such as:
- muscle spasms
- seizure or fits
Taking senna for many weeks, even months, could also stop your bowel working properly on its own.
There are various types of laxatives. Senokot is a stimulant laxative.
The NICE (national institute for health and care excellence) guidelines recommend a stepped approach, so first trying bulk-forming laxatives and moving along the chain if unsuccessful and constipation symptoms remain.
- Bulk-forming (like Fybogel)- increases the weight of the stool, which makes you feel you want to go to the toilet. These laxatives take 2 or 3 days to work.
- Osmotic - draws water into the bowel, making the stool softer and easier to pass. These laxatives take at least 2 days to work.
- Stimulants (like Senokot) - stimulates the muscles of the gut, making the bowel work harder to move stools along. These laxatives usually take 8-12 hours to work.
Senokot does not affect any type of contraception, including the combined pill and emergency contraception, unless you have severe diarrhoea for more than 24 hours.
If you have severe diarrhoea your contraceptive pills may not protect you from pregnancy. Look on the pill packet to find out what to do or contact a healthcare professional for further advice.

It might help to eat less of foods such as pastries, puddings, sweets, cheese and cake for a while, as these foods can make constipation worse.
