## What is senna?

Senna is also known as Cassia, Fan Xie Ye, Alejandrina, Séné, Sennae, and Tinnevelly.

Senna is likely effective in alternative medicine as an aid in treating occasional constipation in adults and children at least 2 years old. Senna is sometimes used together with another laxative or stool softener such as lactulose, psyllium, docusate, or mineral oil.

Senna is possibly effective as a bowel preparation before colonoscopy.

Other uses not proven with research include weight loss, irritable bowel syndrome, hemorrhoids, anal fissures (tears in the lining of the anus), or after anal or rectal surgery.

It is not certain whether senna is effective in treating any medical condition. Medicinal use of this product has not been approved by the FDA. Senna should not be used in place of medication prescribed for you by your doctor.

Senna is often sold as an herbal supplement. There are no regulated manufacturing standards in place for many herbal compounds and some marketed supplements have been found to be contaminated with toxic metals or other drugs. Herbal/health supplements should be purchased from a reliable source to minimize the risk of contamination.

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

## Warnings

Follow all directions on the product label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

## Before taking this medicine

You should not use senna if you are allergic to it, or if you have:

- diarrhea or loose stools;

- severe stomach pain;

- swelling or a blockage in your digestive tract (stomach or intestines);

- Crohn's disease, ulcerative colitis, appendicitis;

- hemorrhoids, anal prolapse; or

- if you are dehydrated.

Ask a doctor, pharmacist, or other healthcare provider if it is safe for you to use this product if you have ever had:

- an electrolyte imbalance (such as low levels of potassium in your blood);

- any change in bowel habits that has lasted longer than 2 weeks;

- long-term bowel problems;

- heart disease; or

- stomach pain, nausea, or vomiting.

Ask a doctor before using this medicine if you are pregnant or breastfeeding.

Some forms of senna are made for use by children. Do not give any herbal/health supplement to a child without the advice of a doctor.

## How should I take senna?

When considering the use of herbal supplements, seek the advice of your doctor. You may also consider consulting a practitioner who is trained in the use of herbal/health supplements.

If you choose to use senna, use it as directed on the package or as directed by your doctor, pharmacist, or other healthcare provider. Do not use more of this product than is recommended on the label.

You must chew the chewable tablet before you swallow it.

Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

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

Do not use different formulations of senna (such as tablets and liquid) at the same time without medical advice. Using different formulations together increases the risk of an overdose of senna.

Senna may be unsafe when taken long-term or in high doses. Using senna for longer than 2 weeks may cause your bowels to stop functioning normally. Long-term use may also cause a serious electrolyte imbalance. Certain electrolyte imbalances can cause muscle weakness, heart problems, liver damage, and other harmful effects.

Call your healthcare provider if your constipation does not improve after 1 week of using senna, or if constipation gets worse.

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