This medication comes in several strengths. Be sure you are using the correct strength. The higher strength product should only be used if you have been using opioid pain medications for a long time. Use of the higher strength medication by someone who is not regularly using opioid pain relievers can cause very serious (possibly fatal) breathing problems.

Ask your doctor or pharmacist if you should have naloxone available to treat opioid overdose. Teach your family or household members about the signs of an opioid overdose and how to treat it.

Hydromorphone has a risk for abuse and addiction, which can lead to overdose and death. Hydromorphone may also cause severe, possibly fatal, breathing problems. To lower your risk, your doctor should have you use the smallest dose of hydromorphone that works, and use it for the shortest possible time. See also How to Use section for more information about addiction.

The risk for severe breathing problems is higher when you start this medication and after a dose increase, or if you use the wrong dose/strength. Using this medication with alcohol or other drugs that can cause drowsiness or breathing problems may cause very serious side effects, including death. Be sure you know how to use hydromorphone and what other drugs you should avoid using with it. See also Drug Interactions section. Get medical help right away if any of these very serious side effects occur: slow/shallow breathing, unusual lightheadedness, severe drowsiness/dizziness, difficulty waking up.

Keep this medicine in a safe place to prevent theft, misuse, or abuse. If someone accidentally swallows this drug, get emergency help right away.

Before using this medication, women of childbearing age should talk with their doctor(s) about the risks and benefits. Tell your doctor if you are pregnant or if you plan to become pregnant. During pregnancy, this medication should be used only when clearly needed. It may slightly increase the risk of birth defects if used during the first two months of pregnancy. Also, using it for a long time or in high doses near the expected delivery date may harm the unborn baby. To lessen the risk, use the smallest effective dose for the shortest possible time. Babies born to mothers who use this drug for a long time may develop severe (possibly fatal) withdrawal symptoms. Tell the doctor right away if you notice any symptoms in your newborn baby such as crying that doesn't stop, slow/shallow breathing, irritability, shaking, vomiting, diarrhea, poor feeding, or difficulty gaining weight.

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.

If you have ongoing pain (such as due to cancer), your doctor may direct you to also take long-acting opioid medications. In that case, this medication might be used for sudden (breakthrough) pain only as needed. Other pain relievers (such as acetaminophen, ibuprofen) may also be prescribed. Ask your doctor or pharmacist about using hydromorphone safely with other drugs.

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.

When this medication is used for a long time, it may not work as well. Talk with your doctor if this medication stops working well.
