WARNING: SERIOUS AND LIFE-THREATENING RISKS FROM USE OF DILAUDID INJECTION
Addiction, Abuse, and Misuse
Because the use of DILAUDID INJECTION exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death, assess each patient's risk prior to prescribing and reassess all patients regularly for the development of these behaviors and conditions
Life-Threatening Respiratory Depression
Serious, life-threatening, or fatal respiratory depression may occur with use of DILAUDID INJECTION, especially during initiation or following a dosage increase. To reduce the risk of respiratory depression, proper dosing and titration of DILAUDID INJECTION are essential
Risks From Concomitant Use With Benzodiazepines Or Other CNS Depressants
Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death
Neonatal Opioid Withdrawal Syndrome (NOWS)
Advise pregnant women using opioids for an extended period of time of the risk of Neonatal Opioid Withdrawal Syndrome, which may be life-threatening if not recognized and treated. Ensure that management by neonatology experts will be available at delivery
1INDICATIONS AND USAGE
DILAUDID INJECTION is indicated for the management of pain severe enough to require an opioid analgesic and for which alternate treatments are inadequate.
Limitations of Use:
- Because of the risks of addiction, abuse, misuse, overdose, and death, which can occur at any dosage or duration, and persist over the course of therapy
2DOSAGE FORMS AND STRENGTHS
DILAUDID INJECTION:
Each single-dose prefilled syringe contains 0.2 mg/mL, 0.5 mg/0.5 mL, 1 mg/mL or 2 mg/mL of hydromorphone hydrochloride in a sterile, aqueous solution.
3CONTRAINDICATIONS
DILAUDID INJECTION is contraindicated in patients with:
- Significant respiratory depression
- Acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment
- Known or suspected gastrointestinal obstruction, including paralytic ileus
- Hypersensitivity to hydromorphone, hydromorphone salts, any other components of the product, or sulfite containing medications (e.g., anaphylaxis)
4ADVERSE REACTIONS
The following serious adverse reactions are described, or described in greater detail, in other sections:
- Addiction, Abuse, and Misuse
- Life-Threatening Respiratory Depression
- Interactions with Benzodiazepines and Other CNS Depressants
- Neonatal Opioid Withdrawal Syndrome
- Opioid-Induced Hyperalgesia and Allodynia
- Adrenal Insufficiency
- Severe Hypotension
- Gastrointestinal Adverse Reactions
- Seizures
- Withdrawal
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 DILAUDID INJECTION 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.

Safety and Handling Instructions
Discard any unused portion.
Access to drugs with a potential for abuse such as DILAUDID INJECTION presents an occupational hazard for addiction in the health care industry. Routine procedures for handling controlled substances developed to protect the public may not be adequate to protect health care workers.
Implementation of more effective accounting procedures and measures to restrict access to drugs of this class (appropriate to the practice setting) may minimize the risk of self-administration by health care providers.
