Senna is a stimulant laxative used to treat short term constipation. It takes around 8 hours for the laxative effect to work, which means it’s best taken at night. It should not be used to treat chronic constipation.

What is Senna?

Senna is a natural laxative made from the leaves and fruit of the senna plant. It used to treat constipation. Constipation is a common condition that can affect people of all ages.

Constipation means that you are unable to pass stools as regularly and easily as you normally can. Some people find it difficult to completely empty their bowel. Senna 7.5 mg tablets can be used to help relieve constipation and make it easier to pass stools.

The tablets contain Senna/Sennosides and can be used for the short term relief of occasional constipation. It’s a type of laxative called a stimulant laxative.

How does Senna work?

Senna is a stimulant laxative. This means it stimulates the muscles in your gut, which helps the muscles to move stools along your bowel. This is the reason for the Senna laxative effect and helps with constipation and makes it easier to pass stools.

How long does Senna take to work?

It takes around 8 hours for the medicine to work. For this reason, most people are advised to take it before bed. This gives the medicine time to work overnight and should help you go to the toilet in the morning. Senna tablets should only be used for a short time.

Using Senna Tablets

The Senna tablets dosage is one or two tablets should be taken at night. It’is only appropriate to treat adults and children over 12 years old.

It should be used for the short term treatment of constipation. Long term use of stimulant laxatives is not recommended because it can cause your bowel to stop functioning by itself. If you have more problematic, long term constipation it is best to seek advice from your doctor.

If, after three days of use, no bowel movement has occurred, you should consult your pharmacist or doctor. 


Senna medication is an effective laxative, however, everyone responds differently to medication. Depending on the cause of your constipation, another class of laxative may be more appropriate. If it’s ineffective for you, it may be appropriate to try another type of laxative after speaking to your GP.


Alternative laxatives available from Simple Online Pharmacy UK include:

  • Senokot - contains the same active ingredient as senna.
  • Senokot Max Strength - contains the same active ingredient as Senna
  • Lactulose - an osmotic laxative that aims to increase the fluid into the bowel.
  • Bisacodyl - a stimulant laxative that acts in a similar way to senna.
  • Fybogel - a bulk-forming laxative that aims to increase the fibre in the bowel.
  • Glycerin Suppositories - A stimulant laxative that has a fast acting, local effect.

Following certain lifestyle measures can also help improve constipation. This includes increasing your fluid and fibre intake, increasing how much you exercise, and eating more fruit and vegetables.

If implementing the above lifestyle measures are ineffective in easing your constipation, it may be appropriate to treat your constipation with a laxative.

Senna Vs Senokot Max Strength

Senokot Max Strength contains the active ingredient senna but at a higher strength. This means that only ONE tablet can be taken at night rather than up to two as with senna tablets. Other brands of this medication include Care Senna tablets.

Pregnancy and Breastfeeding

Senna is not advised to be used during pregnancy or if you are breastfeeding.

If you are suffering constipation during pregnancy you should consult your pharmacist or doctor who can recommend a suitable medication.
