Morphine has a high risk for abuse and severe, possibly fatal, breathing problems. The risk for harm is higher if you take the wrong dose/strength, or if you take it along with other drugs that might also affect breathing. Be sure you know how to take morphine and what other drugs you should avoid taking with it. Get immediate medical help if you notice unusual slow/shallow breathing.
The higher strengths of this drug (100 or 200 milligrams per capsule) should be used only if you have been regularly taking moderate to large amounts of narcotic pain medication. These strengths may cause overdose (even death) if taken by a person who has not been regularly taking narcotic medication. Do not crush, chew, or dissolve this medication or the contents of the capsules. Taking crushed, chewed, or dissolved forms of sustained-action morphine could cause overdose.
