What is rectal hydromorphone?
Hydromorphone is an opioid pain medication. An opioid is sometimes called a narcotic.
Hydromorphone rectal is used to treat moderate to severe pain.
Hydromorphone rectal may also be used for purposes not listed in this medication guide.
What is the most important information I should know about rectal hydromorphone?
Hydromorphone can slow or stop your breathing. Never use this medicine in larger amounts, or for longer than prescribed. Do not crush, break, or open an extended-release pill. Swallow it whole to avoid exposure to a potentially fatal dose. Hydromorphone may be habit-forming, even at regular doses. Never share this medicine with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it.
MISUSE OF NARCOTIC MEDICATION CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.
You should not use rectal hydromorphone if you have a brain tumor or head injury, severe asthma, or breathing problems caused by curvature of the spine, emphysema, COPD, or other lung problems.
Tell your doctor if you are pregnant. Hydromorphone may cause life-threatening addiction and withdrawal symptoms in a newborn.
Do not drink alcohol. Dangerous side effects or death can occur when you drink alcohol while using rectal hydromorphone.
What should I discuss with my healthcare provider before using rectal hydromorphone?
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 head injury; or
curvature of the spine that affects breathing.
To make sure rectal hydromorphone is safe for you, tell your doctor if you have:
any type of breathing problem or lung disease;
a history of seizures;
a history of drug abuse, alcohol addiction, or mental illness;
a stomach or intestinal disorder;
liver or kidney disease;
Addison's disease or other adrenal gland disorders; or
a thyroid disorder.
Hydromorphone is more likely to cause breathing problems in older adults and people who are severely ill, malnourished, or otherwise debilitated.
FDA pregnancy category C. It is not known whether rectal hydromorphone will harm an unborn baby. Hydromorphone may cause breathing problems, behavior changes, or life-threatening addiction and withdrawal symptoms in your newborn if you use the medication during pregnancy. Tell your doctor if you are pregnant.
It is not known whether rectal hydromorphone passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using this medicine.
How should I use rectal hydromorphone?
Hydromorphone may be habit-forming, even at regular doses. Never share this medicine with another person, especially someone with a history of drug abuse or addiction. MISUSE OF NARCOTIC MEDICATION CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription. Selling or giving away hydromorphone is against the law.
Follow all directions on your prescription label. Hydromorphone can slow or stop your breathing. Never use rectal hydromorphone in larger amounts, or for longer than prescribed. Tell your doctor if the medicine seems to stop working as well in relieving your pain.
Do not take a hydromorphone rectal suppository by mouth. It is for use only in your rectum.
Wash your hands before and after inserting the rectal suppository.
Try to empty your bowel and bladder just before using the hydromorphone suppository.
Remove the wrapper before inserting the suppository. Avoid handling the suppository too long or it will melt in your hands.
Lie on your back with your knees up toward your chest. Gently insert the suppository into your rectum about 1 inch, pointed tip first.
For best results, stay lying down for a few minutes. The suppository will melt quickly and you should feel little or no discomfort while holding it in. Avoid using the bathroom for at least an hour after using the suppository.
If you need surgery, tell the surgeon ahead of time that you are using rectal hydromorphone. You may need to stop using the medicine for a short time.
Do not stop using rectal hydromorphone suddenly after long-term use, or you could have unpleasant withdrawal symptoms. Ask your doctor how to avoid withdrawal symptoms when you stop using hydromorphone.
Store in the refrigerator, do not freeze. Protect from light. Keep the medication in a place where others cannot get to it.
Keep track of the number of suppositories used from each new supply. Hydromorphone is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
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 breathing and heart rate, severe drowsiness, muscle weakness, cold and clammy skin, and fainting.
What should I avoid while using rectal hydromorphone?
Do not drink alcohol. Dangerous side effects or death can occur when you drink alcohol while using rectal hydromorphone.
This medication may impair your thinking or reactions. Avoid driving or operating machinery until you know how hydromorphone will affect you. Dizziness or severe drowsiness can cause falls or other accidents.
Rectal hydromorphone side effects
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
Call your doctor at once if you have:
slow heart rate, weak or shallow breathing;
confusion, mood changes, severe anxiety, feeling of fear;
a light-headed feeling, like you might pass out; or
little or no urinating.
Common side effects may include:
weakness, muscle stiffness; or
joint or muscle pain.

Hydromorphone dosing information
Usual Adult Dose for Pain:
Doses should be titrated to appropriate analgesic effects while minimizing adverse effects. When changing routes of administration, it should be noted that oral doses are less than one-half as effective as parenteral doses. Oral doses may be only one fifth as effective as parenteral doses.
Oral liquid: 2.5 to 10 mL every 3 to 6 hours, increasing gradually
Oral tablets: 2 to 4 mg every 4 to 6 hours, increasing gradually
Chronic pain: Oral: Patients taking opioids chronically may become tolerant and require doses higher than the usual dosage range to maintain the desired effect. Tolerance can be managed by appropriate dose titration. There is no optimal or maximal dose for hydromorphone in chronic pain. The appropriate dose is one that relieves pain throughout its dosing interval without causing unmanageable side effects.
IV: Care should be taken to avoid dosing errors due to confusion between the different concentrations and between mg and mL. Hydromorphone HP injection should never be administered to opioid-naïve patients.
Subcutaneous or IM initial dose: 0.2 to 1 mg given slowly every 2 to 3 hours as needed (Lower doses may be used in opioid-naïve patients)
IV initial dose: 0.2 to 1 mg every 2 to 3 hours (given slowly over at least 2 to 3 minutes). The initial dose should be reduced in the elderly or debilitated and may be lowered to 0.2 mg.
Hydromorphone extended release tablets:
Hydromorphone extended release tablets are indicated for opioid tolerant patients only. Patient must not be started on hydromorphone extended release tablets as their first opioid.
Hydromorphone extended release tablets should be swallowed whole and should not be broken, crushed, dissolved, or chewed before swallowing. The tablets are to be administered every 24 hours with or without food.
The dose range of hydromorphone extended release tablets studied in clinical trials is 8 mg to 64 mg.
Patients receiving oral immediate-release hydromorphone may be converted to hydromorphone extended release tablets by administering a starting dose equivalent to the patient's total daily oral hydromorphone dose, taken once daily. The dose of hydromorphone extended release tablets can be titrated every 3 to 4 days until adequate pain relief with tolerable side effects has been achieved.
It is critical to accurately initiate the dosing regimen individually for each patient. Overestimating the hydromorphone extended release tablets dose when converting patients from another opioid medication can result in fatal overdose with the first dose. In the selection of the initial dose of hydromorphone extended release tablets, the following should be noted:
-the daily dose, potency, and specific characteristics of the opioid the patient has been taking previously;
-the reliability of the relative potency estimate used to calculate the equivalent hydromorphone dose needed;
-the patient's degree of opioid tolerance;
-the age, general condition, and medical status of the patient;
-concurrent non-opioid analgesics and other medications, such as those with central nervous system activity;
-the type and severity of the patient pain;
-the balance between pain control and adverse effects;
-risk factors for abuse, addiction, or diversion, including a prior history of abuse, addiction, or diversion.
Dosing recommendations, therefore, can only be considered as suggested approaches to what is actually a series of clinical decisions over time in the management of the pain of each individual patient.
Conversion from oral opioids to hydromorphone extended release tablets:
For conversion from other opioids to hydromorphone extended release tablets, physicians and other healthcare professionals are advised to refer to published relative potency data, keeping in mind that conversion ratios are only approximate. In general, therapy with hydromorphone extended release tablets should be started by administering 50% of the calculated total daily dose of hydromorphone extended release tablets every 24 hours. The initial dose of hydromorphone extended release tablets can be titrated until adequate pain relief with tolerable side effects has been achieved.
Conversion from transdermal fentanyl to hydromorphone extended release tablets:
Eighteen hours following the removal of the transdermal fentanyl patch, hydromorphone extended release tablets treatment can be initiated. For each 25 mcg/hr fentanyl transdermal dose the equianalgesic dose of hydromorphone extended release tablets is 12 mg every 24 hours. An appropriate starting dose of hydromorphone extended release tablets is 50% of the calculated total daily dose every 24 hours.
Individualization of Dosage:
Once therapy is initiated, assess pain relief and other opioid adverse reactions frequently.
Titrate patients to adequate analgesia with dose increases not more often than every 3 to 4 days, in order to attain steady-state plasma concentrations of hydromorphone at each dose.
As a guideline, consider dosage increases of 25% to 50% of the current daily dose of hydromorphone extended release tablets for each titration step.
If more than two doses of rescue medication are needed within a 24 hour period for two consecutive days, the dose of hydromorphone extended release tablets may need to be titrated upward.
Administer hydromorphone extended release tablets no more frequently than every 24 hours.
During periods of changing analgesic requirements, including initial titration, maintain frequent contact between physician, other members of the healthcare team, the patient and the caregiver/family.
Maintenance of Therapy:
During chronic therapy with hydromorphone extended release tablets, assess the continued need for around-the-clock opioid therapy periodically. Continue to assess patients for their clinical risks for opioid abuse, addiction, or diversion particularly with high-dose formulations. If patients need to titrate while on maintenance therapy, follow the same method outlined above to reestablish pain control.
What other drugs will affect rectal hydromorphone?
Using this medicine with other drugs that make you sleepy or slow your breathing can cause dangerous or life-threatening side effects. Ask your doctor before using a sleeping pill, narcotic pain medicine, muscle relaxer, or medicine for anxiety, depression, or seizures.
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.
Other drugs may interact with hydromorphone, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell each of your health care providers about all medicines you use now and any medicine you start or stop using.
