This medication is use to help relieve moderate to severe pain. Hydromorphone belongs to a class of drugs known as opioid (narcotic) analgesics. It works in the brain to change how your body feels and responds to pain.

How to use Dilaudid

• Read the Medication Guide provided by your pharmacist before you start taking hydromorphone and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
• Take this medication by mouth as directed by your doctor. You may take this drug with or without food. If you have nausea, it may help to take this drug with food. Ask your doctor or pharmacist about other ways to decrease nausea (such as lying down for 1 to 2 hours with as little head movement as possible).
• If you are using the liquid form of this medication, carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. Do not confuse the dose of hydromorphone liquid in milligrams (mg) with the dose in milliliters (mL). Ask your pharmacist or doctor if you are not sure how to check or measure the dose. If your liquid is a suspension, shake the bottle well before each dose.
• The dosage is based on your medical condition and response to treatment. Do not increase your dose, take the medication more frequently, or take it for a longer time than prescribed. Properly stop the medication when so directed.
• Pain medications work best if they are used when the first signs of pain occur. If you wait until the pain has worsened, the medication may not work as well.
• Suddenly stopping this medication may cause withdrawal, especially if you have used it for a long time or in high doses. To prevent withdrawal, your doctor may lower your dose slowly. Tell your doctor or pharmacist right away if you have any withdrawal symptoms such as restlessness, mental/mood changes (including anxiety, trouble sleeping, thoughts of suicide), watering eyes, runny nose, nausea, diarrhea, sweating, muscle aches, or sudden changes in behavior.

  Tell your doctor if your pain does not get better or if it gets worse.
