Key takeaways
Calcium polycarbophil (FiberCon) and senna (Senokot) are both over-the-counter medications used to treat occasional constipation, but they work in different ways. Calcium polycarbophil is a bulk-forming laxative that adds water to your stool, making it heavier and easier to pass. It usually takes 12 to 72 hours to work and is less likely to cause gas and bloating compared to natural fiber supplements, like Metamucil. On the other hand, senna is a stimulant laxative that activates the muscles in your intestines to push out stool, typically working within 6 to 12 hours. While senna works faster, it can cause stomach cramps and is not recommended for long-term use. Calcium polycarbophil is considered gentler and is also a fiber supplement, whereas senna is purely a stimulant laxative. Both medications should not be used for more than a week without consulting a healthcare professional.
