Magic Bullet Suppository is a bisacodyl suppository that is water soluble so it works to produce a bowel movement fast. The active ingredient, 10 mg bisacodyl, disperses within minutes of insertion because the suppository does not have a hydrogenated vegetable oil base. Vegetable oil takes time to work because it takes time for it to melt. The bisacodyl stimulates the bowels which is what produces a bowel movement. The short shelf life is because it is a water soluble suppository which shortens the shelf life but it makes the Magic Bullet a much more effective suppository. Express Medical Supply sells Magic Bullet suppositories in packs of 10 and boxes of 100 for your convenience so you can buy the amount you need without having to be concerned about the expiration date. Concepts in Confidence Magic Bullets are fast acting and reliable which makes them an effective addition to your bowel programs.
