Senna

Generic name: Senna
Drug class: Laxatives

Usage of 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. It 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 side effects

Get emergency medical help if you have signs of an allergic reaction to senna: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Stop using senna and call your doctor at once if you have:

rectal bleeding;

no bowel movement within 12 hours after using senna; or

low potassium level - leg cramps, constipation, irregular heartbeats, fluttering in your chest, increased thirst or urination, numbness or tingling, muscle weakness or limp feeling.

Constipation is the most common side effect of senna. Less serious side effects may be more likely, and you may have none at all.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

How to use 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 (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 this medicine 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 use, or if your constipation gets worse.

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