Why is this medication prescribed?

Constipation is treated temporarily with senna. Additionally, it is utilised to relieve intestinal obstructions before to surgery and other medical treatments. Senna belongs to the group of drugs known as stimulant laxatives. It induces a bowel movement by causing the intestines to work harder.

How should this medicine be used?

Senna is available as a liquid, powder, granule, chewable piece, and oral tablet. You can take it once or twice a day. Senna can be taken at night to induce a bowel movement the following day because it typically induces a bowel movement within 6 to 12 hours. Senna should not be taken for longer than a week without consulting a physician. Ask your doctor or pharmacist to explain any instructions on your box or prescription label that you do not understand, and make sure you carefully follow all other instructions. Senna should be taken as prescribed. Senna use on a regular basis or for an extended period of time may result in dependence on laxatives and loss of normal bowel function. Senna should not be used again if you do not experience a regular bowel movement after taking it. Instead, consult your doctor.

You should consume the pills whole with a glass of water if you’re taking certain senna products (Ex-Lax® normal or maximum strength tablets or Perdiem Overnight Relief); do not split, chew, or crush them.

  • If you are 65 years of age or older, discuss the advantages and disadvantages of taking senna with your doctor. Senna products are often not advised for usage by older persons over an extended length of time since they are less safe than other treatments for the same ailment.

What should I know about storage and disposal of this medication?

Keep this medication tightly closed in the original container and out of the reach of children. Store it away from excessive heat and moisture at room temperature (not in the bathroom).

As many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning.

Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilising a medicine take-back programme is the easiest approach to get rid of your medication. To find out about take-back programmes in your area, speak with your pharmacist or the garbage/recycling department in your city. If you do not have access to a take-back programme, see the FDA’s Safe Disposal of Medicines website at for additional information.

In case of emergency/overdose

Call the poison control hotline at 1-800-222-1222 in the event of an overdose. Additionally, information can be found online at Call 911 right once if the person has collapsed, experienced a seizure, is having difficulty breathing, or cannot be roused.

What other information should I know?

If you have any inquiries about senna, ask your pharmacist.

You should keep a written record of every medication you take, including any over-the-counter (OTC) items, prescription drugs, and dietary supplements like vitamins and minerals. This list should be brought with you whenever you see a doctor or are admitted to the hospital. You should always have this information with you in case of emergencies.
