Morphine Overview

• Morphine is used to relieve moderate to severe pain. Morphine extended-release tablets and capsules are only used to relieve severe (around-the-clock) pain that cannot be controlled by the use of other pain medications. Morphine extended-release tablets and capsules should not be used to treat pain that can be controlled by medication that is taken as needed. Morphine is in a class of medications called opiate (narcotic) analgesics. It works by changing the way the brain and nervous system respond to pain.

Cannabidiol Overview

• Cannabidiol is used to control seizures in adults and children 1 year of age and older with Lennox-Gastaut syndrome (a disorder that begins in early childhood and causes seizures, developmental delays, and behavioral issues), Dravet syndrome (a disorder that begins in early childhood and causes seizures and later may lead to developmental delays and changes in eating, balance, and walking), or tuberous sclerosis complex (TSC; a genetic condition that causes tumors to grow in many organs). Cannabidiol is in a class of medications called cannabinoids. It is not known exactly how cannabidiol works to prevent seizure activity.
