Hydromorphone may be habit forming. Take hydromorphone exactly as directed. Do not take more or less of it, take it more often, stop using it suddenly, or take it in a different way than directed 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 has had an overdose, or if you have or have ever had depression or another mental illness.
Hydromorphone may cause serious or life-threatening breathing problems, especially during the first 24 to 72 hours of your treatment and any time your dose is increased. If you experience any of the following symptoms, call your doctor immediately or get emergency medical treatment: slowed breathing, long pauses between breaths, or shortness of breath.
Taking certain other medications, drinking alcohol, or using street drugs during your treatment with hydromorphone may increase the risk that you will develop serious or life-threatening breathing problems, sedation, or coma. Tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, and nutritional supplements you are taking or plan to take. Your doctor may need to change the doses of your medications and will monitor you carefully.
Hydromorphone may harm or cause death to other people who take your medication, especially children. Keep hydromorphone in a safe place so that no one else can take it accidentally or on purpose.
Tell your doctor if you are pregnant or plan to become pregnant. If you take hydromorphone regularly during your pregnancy, your baby may experience life-threatening withdrawal symptoms after birth.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin your treatment with hydromorphone and each time you fill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website ( https://www.fda.gov/Drugs/DrugSafety/ucm085729.htm ) or the manufacturer's website to obtain the Medication Guide.Talk to your doctor about the risks of taking hydromorphone.
Why is this medicine prescribed?
Hydromorphone is used to relieve severe pain. Hydromorphone is in a class of medications called opiate (narcotic) analgesics. It works by changing the way the brain and nervous system respond to pain.
Are there other uses for this medicine?
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
How should this medicine be used?
Hydromorphone comes as a solution (liquid) and a tablet to take by mouth. The liquid is usually taken every 3 to 6 hours and the tablets are usually taken every 4 to 6 hours as needed for pain.
Use a dose-measuring spoon or cup to measure the correct amount of hydromorphone solution for each dose, not a regular household spoon. Mix your dose with half a glass of water and swallow the mixture. Ask your doctor or pharmacist if you need help getting or using a measuring device.
Your doctor may adjust your dose of hydromorphone 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. Tell your doctor if you feel that your pain is not controlled or if your pain increases, becomes worse, or if you have new pain or an increased sensitivity to pain during your treatment with hydromorphone. Do not take more of it or take it more often than prescribed by your doctor.
Talk to your doctor or pharmacist about access to rescue medicines, naloxone or nalmefene, while taking hydroxymorphone. Rescue medications can reverse the life-threatening effects of an opioid overdose and are available over the counter or with a prescription. Make sure that you and your family members and people usually around you know how to recognize an overdose, how to use naloxone or nalmefene, and what to do until emergency medical help arrives. Your doctor or pharmacist will show you and others how to use it. If symptoms of an overdose occur, they should give the first dose of naloxone, call 911 immediately, and stay with you and watch you closely until emergency medical help arrives. If your symptoms return, the person should give you another dose of the rescue medication. Additional doses may be given every 2 to 3 minutes, if symptoms return before medical help arrives.
Do not stop taking hydromorphone without talking to your doctor. Your doctor will probably decrease your dose gradually. If you suddenly stop taking hydromorphone, you may experience withdrawal symptoms including restlessness, teary eyes, runny nose, yawning, sweating, chills, hair standing on end, muscle or joint pain, widening of the pupils (black circles in the middle of the eyes), irritability, anxiety, backache, weakness, stomach cramps, difficulty falling asleep or staying asleep, nausea, loss of appetite, vomiting, diarrhea, fast breathing, or fast heartbeat.
