List of Medications


Morphine is a custom pharmacy drug classified in the family of drugs known as opiate (narcotic) analgesics. It is an opioid pain medication used to treat moderate to severe pain, often in cases where other pain medications may be ineffective or insufficient. Morphine works within the brain and nervous system to affect the way they interpret pain signals.


Morphine may be delivered to the body in multiple forms from tablets to injections. Commonly, morphine is delivered via solutions, extended-release tablets, and extended-release capsules, all of which are taken orally. Solutions are typically taken every four hours or as directed by your doctor. Tablets are typically taken every eight to twelve hours, or as directed by your doctor, and capsules are taken every twelve to twenty-four hours, or again, as directed by your doctor. Ask your doctor about how to take your form of morphine, whether you should take it with food or without, etc. If prescribed morphine, never stop taking it without first consulting with your doctor.
