A capsule contains medication, normally within a small container that is digested by the body. Rarely, a capsule may not be digested, and you will see it in the toilet after you use the restroom.
Time release capsule should not crushed or chewed, which may result in a drug overdose. These capsules are made to be taken once a day, and release a small amount of drug over 24 hours. Crushing, chewing, or opening a time-release capsule destroys it, and will make you receive the medication for one day in only a few minutes. In some situations, this can kill a person.
Examples of capsules: Nexium, zidovudine
