Senokot: Uses, Presentations, Administration, Contraindications, Side Effects and Warnings

It is used to relieve occasional constipation that is not caused by other medications or medical conditions.

This medicine works by increasing muscle activity in the digestive system, causing waste material to pass as a stool. You usually have a bowel movement between 6 and 12 hours after taking medicine.

Senokot is a trademark of Senna, a natural plant laxative used to treat constipation. It can also be given to empty the intestines before specific medical procedures or surgeries.

Senokot is a stimulating laxative. It works by irritating the intestinal tissues, resulting in bowel movements.

The active ingredient in Senokot is purified Senna, which is derived from the senna plant. This remedy has been used for centuries to relieve constipation.

Senokot has been sold as an over-the-counter (OTC) remedy since 1955. Purdue Pharma manufactures the drug.

Is senna herb safe to take as a laxative?

It’s okay to take senna laxatives for occasional constipation when used as directed. The labels advise against taking them for more than a week, but we recommend limiting them to a few days.


From the leaves of the Senna alexandrina shrub, Senna has been used as a herbal digestive remedy for centuries. Its key components are called sennosides (senna glycosides), which generally produce a bowel movement in 6 to 12 hours.

Although sold as a herbal supplement, Senna is also approved by the Food and Drug Administration for short-term use as a stimulant laxative and is found in over-the-counter products such as Senokot and Ex-Lax.

Senna is just one of several stimulant laxatives that increase the intestinal muscles’ contractions to move stool. Another stimulant is bisacodyl, found in Dulcolax, which may have fewer side effects.

Many people choose these laxatives because they work quickly, but they can cause colic and diarrhea. When taken longer-term, they can affect bowel function and cause laxative dependence.

The most severe concern about the overuse of stimulant laxatives is that they can cause a dangerous loss of electrolytes (including potassium).

Senna and other herbal laxatives are sometimes promoted as diet aids. But this is a dangerous way to lose weight, and it doesn’t reduce body fat, and the pounds will quickly return when you stop taking the laxative.

It is best not to rely on a laxative, especially a stimulant.

If you have chronic or recurring constipation, see your healthcare provider ensure there is no underlying problem (such as a low thyroid) and discuss “gut-friendly” lifestyle changes.

That includes a high-fiber diet (more fruits, whole grains, beans, vegetables, and increased fluid intake) and regular exercise (such as daily walking).

If you need a laxative on an ongoing basis, bulking types containing psyllium (such as Metamucil) or other fiber types are the only good options.

Polyethylene glycol (such as Miralax) is gentler than stimulant types for short-term use. You can also try this self-help technique.

How Senokot Relieves Constipation

Take this medication by mouth with a full glass of water (8 ounces / 240 milliliters) as directed by your doctor. If you are treating yourself, follow all instructions on the product package. If you are not sure about the information, ask your doctor or pharmacist.

Senokot works in different ways and the effectiveness of each type of laxative varies from person to person. In general, bulk-building laxatives, also known as fiber supplements, are the gentlest on your body and the safest to use long-term.

Even though many laxatives are available without a prescription, it’s best to talk to your doctor about using laxatives and which one is best for you.

Oral laxatives can interfere with the absorption of some medications and nutrients in your body. Some laxatives can cause an electrolyte imbalance, especially after prolonged use.

Electrolytes regulate several bodily functions, including calcium, chloride, potassium, magnesium, and sodium. An electrolyte imbalance can cause abnormal heart rhythms, weakness, confusion, and seizures.

Take Senokot with caution. If you rely on Senokot to have a bowel movement, ask your doctor for suggestions on gradually withdrawing from them and restoring your colon’s natural ability to contract.

  • Thirst, muscle aches or cramps; dry mouth; numbness of the hands, feet, or lips; or fast heartbeat, contact your doctor as soon as possible.

If you take Senokot and it doesn’t help with your constipation or rectal bleeding occurs, stop using this medicine and see your doctor.
