Senna Coupons & Prices

Senna (sennosides) is an over-the-counter stimulant laxative used for the short-term relief of occasional constipation, sold under familiar brand names like Senokot and Ex-Lax. Because it is available without a prescription, you can buy it directly off the shelf, but a senna coupon from Rx.com may lower your cost at the pharmacy counter, and some shoppers pay less when a larger or store-brand size is run through a discount card.

What is senna and how does it work?

Senna is a stimulant laxative made from the senna plant. Its active ingredients, sennosides A and B (also called senna glycosides), are anthraquinones. After you swallow a dose, bacteria in your colon break the sennosides down into compounds that stimulate the muscles of the intestine to contract. This increased movement, along with more fluid drawn into the bowel, produces a bowel movement, usually within 6 to 12 hours.

It has FDA-approved OTC use for the short-term relief of occasional constipation. Senna is also commonly used to help empty the bowel before a colonoscopy, surgery, or other medical procedure, often alongside other agents. It is frequently paired with the stool softener docusate (as in Senokot-S) for constipation caused by opioid pain medicines.

How to save on senna with an Rx.com coupon

Senna is inexpensive and widely stocked, but prices still vary from store to store and between brand names like Senokot and Ex-Lax and their generic sennoside equivalents. Because senna is available both as an OTC product and, in some cases, as a pharmacy item, an Rx.com discount coupon can sometimes bring the register price below the sticker price, and larger bottles or store brands are often the better value per dose.

Senna vs. other laxatives

Senna is a stimulant laxative, which is only one of several ways to treat constipation. The right choice depends on how quickly you need relief and how gentle you want the effect. Common alternatives include:

• Bisacodyl (Dulcolax) - another stimulant laxative that works in a similar way.
• Docusate - a stool softener that is gentler and often combined with senna for opioid-related constipation.
• Polyethylene glycol (MiraLAX) - an osmotic laxative that draws water into the stool.
• Lactulose - a prescription osmotic laxative.
• Magnesium citrate - a saline laxative often used for faster, stronger emptying before procedures.

Stimulant laxatives like senna are generally meant for short-term use, while some osmotic options may be used a bit longer under a doctor's guidance. Ask your pharmacist or provider which type fits your situation.

Safety, side effects, and who should be cautious

Senna has no boxed warning, but it is intended for short-term use only. Do not use it for more than 1 week without talking to a doctor, because prolonged or chronic use can lead to laxative dependence, loss of normal bowel function, and electrolyte disturbances. Do not use senna if you have abdominal pain, nausea, or vomiting, or if you have had a sudden change in bowel habits lasting more than 2 weeks. Stop and seek care if you notice rectal bleeding or you do not have a bowel movement after using it, since these can signal a more serious condition. Avoid taking senna together with mineral oil.

Common side effects include abdominal cramps, stomach discomfort, diarrhea, and a harmless discoloration of the urine. If you are pregnant or breastfeeding, talk to your doctor before using senna. Adults 65 and older should use it only short-term and with extra caution. This information is not medical advice; check with your pharmacist or provider if you have questions about your situation.
