What is senna?

Senna is an herb that is also called Alexandrian Senna, Casse, Fan Xie Ye, Indian Senna, Khatoum Senna, Sen, Sena Alejandrina, Sennae Folium, Sennae Fructus, Sennosides, Tinnevelly Senna, True Senna, and other names.

Senna is likely helpful in alternative medicine for treating occasional constipation in adults and children who are at least 2 years old.

Senna has been used in alternative medicine as a possibly effective way to help empty the bowel before a colonoscopy.

Other uses that have not been proven with research include weight loss, irritable bowel syndrome, hemorrhoids, and other conditions.

It is not clear if senna is effective for treating any medical condition. The FDA has not approved this product for medicinal use. Senna should not be used instead of medication your doctor has prescribed.

Senna is often sold as an herbal supplement. Many herbal products do not have regulated manufacturing standards, and some supplements have been found to be contaminated with toxic metals or other drugs. Herbal/health supplements should be bought from a trustworthy source to reduce the risk of contamination.

Senna may also be used for purposes not listed in this product guide.

How should I take senna?

When thinking about using senna, ask your doctor for advice. You may also want to talk to a practitioner who knows about herbal or health supplements.

If you decide to use senna, follow the instructions on the package or those given by your doctor, pharmacist, or other healthcare provider. Do not use more of this product than what is recommended on the label.

Swallow the tablet whole with a full glass of water and do not crush, chew, or break it.

You must chew the chewable tablet before you swallow it.

Measure the liquid product using the provided measuring device (not a kitchen spoon).

Taking more than your recommended dose will not make this product work better and may lead to serious side effects.

Senna should cause a bowel movement within 6 to 12 hours after you take it.

Do not use different forms of senna (tablets, liquids, and others) at the same time, as this could lead to an overdose.

Contact your healthcare provider if your constipation does not improve after 1 week of using senna, or if it gets worse. Do not take senna for longer than 1 week unless your healthcare provider has instructed you to.

Store at room temperature away from moisture, heat, and light.
