Key takeaways
Dilaudid (hydromorphone) and fentanyl (Fentora, Actiq) are prescription opioids. They treat pain that isn't relieved by non-opioid pain medications. Fentanyl is often used for cancer pain. They’re not first-choice options for pain since they have significant risks, such as misuse and overdose, that can be life-threatening. Common side effects, however, can often be managed at home. These include drowsiness, dizziness, and constipation. Both medications come in several forms. For example, Dilaudid is available as tablets, oral liquid, and injection. Fentanyl is available as patches, lozenges, an injection, and more. If you or someone in your household takes Dilaudid or fentanyl, you should carry naloxone (Narcan) with you. Naloxone can rapidly reverse the effects of an opioid overdose if needed.
