What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

Description

Senokot (Sennosides) is a laxative derived from natural vegetable extracts, mainly from the senna plant. It’s classified as a stimulant laxative that works by stimulating the muscles in the gut to promote bowel movements. People commonly use Sennosides to relieve occasional constipation or prepare the intestines before surgical procedures. The drug is often taken in tablet form and typically offers relief within 6 to 12 hours.

Ask a doctor before using Senokot if you have stomach pain, nausea or vomiting, or a sudden change in bowel habits that has lasted more than 2 weeks, as these may be signs of a more serious problem.

Stop using Senokot and call a doctor if you have rectal bleeding or do not have a bowel movement after using it, as these symptoms could indicate a more serious problem.

If someone takes too much, get medical help or contact a Poison Control Center right away.

Side Effects

Senokot may cause side effects, which can vary from mild to severe. Common side effects include stomach cramps, abdominal pain, and diarrhea. Some individuals might experience an urgent need for a bowel movement, nausea, or gas.

In rare cases, some people have reported esophageal impaction or duodenal bezoars. If you experience extreme discomfort or a sudden change in bowel habits persisting beyond 2 weeks, consult a healthcare professional for an evaluation and advice.
