()

6 ADVERSE REACTIONS

The following serious adverse reactions are described, or described in greater detail, in other sections:

Addiction, Abuse, and Misuse [see Warnings and Precautions (5.2)]
Life-Threatening Respiratory Depression [see Warnings and Precautions (5.3)]
Interactions With Benzodiazepines and Other CNS Depressants [see Warnings and Precautions (5.4)]
Neonatal Opioid Withdrawal Syndrome [see Warnings and Precautions (5.5)]
Opioid-Induced Hyperalgesia and Allodynia [see Warnings and Precautions (5.6)]
Adrenal Insufficiency [see Warnings and Precautions (5.8)]
Severe Hypotension [see Warnings and Precautions (5.9)]
Gastrointestinal Adverse Reactions [see Warnings and Precautions (5.11)]
Seizures [see Warnings and Precautions (5.12)]
Withdrawal [see Warnings and Precautions (5.13)]

The following adverse reactions associated with the use of hydromorphone were identified in clinical studies or postmarketing reports. Because some of these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Serious adverse reactions associated with Hydromorphone Hydrochloride Injection [high potency formulation (HPF)] include respiratory depression and apnea and, to a lesser degree, circulatory depression, respiratory arrest, shock, and cardiac arrest.

The most common adverse effects are lightheadedness, dizziness, sedation, nausea, vomiting, sweating, flushing, dysphoria, euphoria, dry mouth, and pruritus. These effects seem to be more prominent in ambulatory patients and in those not experiencing severe pain.
