Hydromorphone rectal is an opioid medication used to treat moderate to severe pain.
Hydromorphone rectal may also be used for purposes not listed in this medication guide.
MISUSE OF OPIOID MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medication in a place where others cannot get to it.
Using opioid medicine during pregnancy may cause life-threatening withdrawal symptoms in the newborn.
Fatal side effects can occur if you use opioid medicine with alcohol, or with other drugs that cause drowsiness or slow your breathing.
Before taking this medicine
You should not use rectal hydromorphone if you have ever had an allergic reaction to a narcotic medicine, or if you have:
severe asthma or breathing problems;
a brain tumor; or
abnormal curvature of the spine that affects breathing.
You should not use rectal hydromorphone if you have used an MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, tranylcypromine, and others.
Tell your doctor if you have ever had:
breathing problems, sleep apnea;
a head injury or seizure;
liver or kidney disease;
a stomach or intestinal disorder;
an enlarged prostate or urination problems;
a thyroid disorder; or
Addison's disease or other adrenal gland disorders.

You should not breastfeed while using rectal hydromorphone.
How should I use rectal hydromorphone?
Follow the directions on your prescription label and read all medication guides. Never use hydromorphone in larger amounts, or for longer than prescribed. Tell your doctor if you feel an increased urge to take more of hydromorphone.
Do not take a hydromorphone rectal suppository by mouth. It is for use only in your rectum.
Never share opioid medicine with another person, especially someone with a history of drug abuse or addiction. MISUSE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medication in a place where others cannot get to it. Selling or giving away opioid medicine is against the law.
Wash your hands before and after inserting the rectal suppository.
Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.
If you need surgery, tell the surgeon ahead of time that you are using rectal hydromorphone.
Do not stop using this medicine suddenly after long-term use, or you could have serious withdrawal symptoms. Ask your doctor how to safely stop using this medicine.
Store in the refrigerator, do not freeze. Protect from light. Keep track of your medicine. You should be aware if anyone is using it improperly or without a prescription.
Do not keep leftover opioid medication. Just one dose can cause death in someone using this medicine accidentally or improperly. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program, flush the unused medicine down the toilet.
What happens if I miss a dose?
Since hydromorphone is used for pain, you are not likely to miss a dose. Skip any missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. A hydromorphone overdose can be fatal, especially in a child who accidentally sucks on or swallows a hydromorphone suppository, or in any other person using the medicine without a prescription. Overdose symptoms may include slow heart rate, severe drowsiness, muscle weakness, cold and clammy skin, very slow breathing, or coma.
What should I avoid while using rectal hydromorphone?
Do not drink alcohol. Dangerous side effects or death could occur.
Avoid driving or operating machinery until you know how hydromorphone will affect you. Dizziness or severe drowsiness can cause falls or other accidents.
