Addiction, Abuse, and Misuse

Hydromorphone Hydrochloride Injection exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death.

Neonatal Opioid Withdrawal Syndrome

Prolonged use of Hydromorphone Hydrochloride Injection during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available [See Warnings and Precautions (5.3)].
