Hydromorphone injection is available as a regular strength solution (Dilaudid) and a concentrated solution (Dilaudid-HP) that contains more hydromorphone in each milliliter of solution. Your doctor should only prescribe the concentrated solution if you are opioid tolerant (have been treated with certain doses of narcotic medications for at least 1 week, allowing your body to adjust to this type of medication). The concentrated solution may cause serious side effects or death if it is used by a person who is not opioid tolerant. Be sure that you know which hydromorphone solution your doctor has prescribed, and always check to be sure you are receiving the correct medication.
Hydromorphone injection may be habit-forming and may cause slowed or stopped breathing or death if it is overused. Do not use more of it or use it more often than prescribed by your doctor. Tell your doctor if you or anyone in your family drinks or has ever drunk large amounts of alcohol, uses or has ever used street drugs, or has overused prescription medications, or if you have or have ever had depression or another mental illness. There is a greater risk that you will overuse hydromorphone injection if you have or have ever had any of these conditions.
Do not allow anyone else to use your medication. Store hydromorphone injection in a safe place so that no one else can use it accidentally or on purpose. Keep track of how much medication is left so you will know if any is missing.
Drinking alcohol or using street drugs during your treatment with hydromorphone injection increases the risk that you will experience serious, life-threatening side effects. Talk to your doctor about the risks of drinking alcohol or using street drugs during your treatment.
Taking certain other medications during your treatment with hydromorphone injection may increase the risk that you will experience serious, life-threatening side effects. Tell your doctor if you are taking or plan to take any of the following medications: other narcotic pain medications; medications for anxiety, seizures, mental illness, or nausea; muscle relaxants; sedatives; sleeping pills; or tranquilizers.
Hydromorphone injection is used to relieve pain. Hydromorphone injection is in a class of medications called opiate (narcotic) analgesics. It works by changing the way the brain and nervous system respond to pain.
Hydromorphone injection comes as a solution (liquid) to inject under the skin, into a vein, or into a muscle. It is usually injected once every 2 to 3 hours as needed. Use hydromorphone injection exactly as directed.
Your doctor may adjust your dose of hydromorphone injection during your treatment, depending on how well your pain is controlled and on the side effects that you experience. Talk to your doctor about how you are feeling during your treatment with hydromorphone injection.

Your doctor will probably decrease your dose gradually.
