Life-Threatening Respiratory Depression
Inform patients of the risk of life-threatening respiratory depression, including information that the risk is greatest when starting preservative-free morphine sulfate injection or when the dosage is increased, and that it can occur even at recommended dosages [see Warnings and Precautions (5.3)].

Advise patients to inform their healthcare provider if they experience symptoms of hyperalgesia, including worsening pain, increased sensitivity to pain, or new pain [see Warnings and Precautions (5.8), Adverse Reactions (6)].
Serotonin Syndrome
