Hydrocodone vs. hydromorphone differences
- Hydrocodone (Zohydro ER) and hydromorphone (Dilaudid, Dilaudid-5, Dilaudid-HP Injection, Exalgo) are both opioid narcotic pain relievers.
- Both hydrocodone and hydromorphone are available as generic drugs.
- Side effects of both hydrocodone and hydromorphone are similar and include lightheadedness, dizziness, sedation, nausea, vomiting, and constipation.
- Hydrocodone may also cause drowsiness and difficulty urinating.
- Hydromorphone may cause side effects including sweating, flushing, itching, and dry mouth.
- Serious side effects of both hydrocodone and hydromorphone include slowed breathing and trouble breathing.
- Combining opioids such as hydrocodone and hydromorphone with alcohol or other central nervous system depressants may result in severe sedation, respiratory depression, coma, and death.
- Both hydrocodone and hydromorphone have the potential for abuse and addiction. Withdrawal symptoms for both drugs include restlessness, watery eyes, runny nose, yawning, sweating, chills, muscle pain, and dilated pupils.
What is hydrocodone? What is hydromorphone? How do they work?
Hydrocodone (Zohydro ER) is an opioid narcotic pain reliever similar to oxycodone, morphine, methadone, fentanyl, and other opioids. Hydrocodone, like other opioids, stimulates receptors on nerves in the brain to increase the threshold to pain and reduce the perception of pain. Hydrocodone is prescribed for the long-term treatment of severe pain for which other treatment options are not effective, not tolerated, or would most likely not be strong enough to adequately manage the pain. Hydrocodone sometimes is combined with other non-narcotic pain relievers such as ibuprofen (Vicoprofen) or acetaminophen (Vicodin, Norco, Lortab, Lorcet).
Hydromorphone hydrochloride (Dilaudid) is an opioid narcotic pain reliever similar to oxycodone, morphine, methadone, fentanyl, and other opioids. It is used for management of acute pain and moderate-to-severe chronic pain in patients when the use of an opioid is appropriate. Hydromorphone, like other opioids, stimulates receptors on nerves in the brain to increase the threshold to pain and reduce the perception of pain.

Hydrocodone is prescribed for the long-term treatment of severe pain for which other treatment options are not effective, not tolerated, or would most likely not be strong enough to adequately manage the pain.
Hydromorphone is used for management of acute pain and moderate-to-severe chronic pain in patients when the use of an opioid is appropriate.
What are the side effects of hydrocodone vs. hydromorphone?
Hydrocodone side effects
The most frequent adverse reactions include:
Other side effects include:
- Spasm of the ureter, which can lead to difficulty in urinating.
Other patient warnings include:
- Hydrocodone can impair thinking and the physical abilities required for driving or operating machinery.
- Hydrocodone can depress breathing and should be used with caution in elderly, debilitated patients, and in patients with serious lung disease.
- Hydrocodone is habit forming. Mental and physical dependence can occur when used long-term.
Hydromorphone HCI BLACK BOX WARNING
- Dilaudid-HP Injection should not be confused with other types of Dilaudid injections or other opioids, as overdose and death could result.
- Avoid dosing errors from confusion between mg and mL when dispensing, prescribing, or administering the oral solution. Dosing errors can result in accidental overdose and death.
- Hydromorphone exposes patients to risks of addictions, abuse, and misuse, which can lead to overdose and death.
- Patients should be monitored closely because serious, life-threatening, or fatal respiratory depression may occur.
- Prolonged use of hydromorphone during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated.
- Pregnant women should be advised of the risk of neonatal opioid withdrawal syndrome and appropriate treatment should be available.
- Combining opioids with benzodiazepines, alcohol, or other central nervous system (CNS) depressants may result in severe sedation, respiratory depression, coma, and death.
Hydromorphone side effects
Common side effects
Other serious side effects
- Other serious and important side effects of hydromorphone are respiratory depression and trouble breathing.
- Since hydromorphone is a controlled narcotic, it carries a box warning of respiratory depression and abuse potential. Use with alcohol or other medications affecting the central nervous system can worsen respiratory depression and may lead to death.
What is the dosage of hydrocodone vs. hydromorphone?
- The initial dose for adults is 10 mg orally every 12 hours.
- The dose may be increased every 3 to 7 days by 10 mg every 12 hours as needed to control pain.
- Capsules must be swallowed whole and not chewed.
- Immediate-release tablets: Take 2 to 4 mg tablets by mouth every 4 to 6 hours as needed. Increase to 8 mg after careful observation and if needed to control pain.
- Extended-release tablets: Start after discontinuation of all other opioid extended-release tablets. Dosed once-daily, individualized based on prior opioid therapy.
- Injections: Give 1 to 2 mg intramuscularly or subcutaneously every 2 to 3 hours as needed. Give 0.2 to 1 mg intravenously over 2 to 3 minutes every 2 to 3 hours as needed.
- Oral solution: Give 2.5 to 10 mg every 3 to 6 hours as needed.
- Rectal suppository: Insert one 3 mg suppository rectally every 6 to 8 hours OR3 to 6 mg rectally every 3 to 4 hours, when appropriate.
Safe and effective use of hydromorphone in children has not been established.
What are the drug interactions of hydrocodone vs. hydromorphone?
Hydrocodone drug interactions
- Combining alcohol and other sedatives with hydrocodone can lead to increased sedation and even cause confusion.
- Hydrocodone should not be taken with any of the monoamine oxidase inhibitor (MAOI) class of antidepressants, for example, isocarboxazid (Marplan), phenelzine (Nardil), tranylcypromine (Parnate), selegiline (Eldepryl), and procarbazine (Matulane) or other drugs that inhibit monoamine oxidase, for example, linezolid (Zyvox). Such combinations may lead to confusion, high blood pressure, tremor, hyperactivity, coma, and death. Hydrocodone should not be administered within 14 days of stopping an MAOI.
Hydromorphone drug interactions
- Hydromorphone should be used very cautiously with medications that depress the central nervous system (for example, hypnotics, anesthetics, tranquilizers, phenothiazines, and alcohol).
- Hydromorphone should be used with caution with mixed agonist/antagonist opioid analgesics (for example, pentazocine, nalbuphine, butorphanol, and buprenorphine) because it may take away the analgesic effect of hydromorphone.
Are these narcotics safe to take if I am pregnant or breastfeeding?
- There are no adequate studies of hydrocodone in pregnant women.
- Hydrocodone is excreted in breast milk, and, therefore should be used cautiously by nursing mothers.
- There are no adequate studies of hydromorphone to determine safe and effective use in pregnant women.
- Low levels of opioid medications may be excreted in breast milk; therefore, it should not be used in nursing mothers.

Laxatives for Constipation
Laxatives types for treatment of constipation include over-the-counter (OTC) preparations, for example, bulk-forming laxatives, stool softeners, lubricant laxatives, stimulant or saline laxatives, enemas, and suppositories. Some OTC laxatives are not recommended for people with specific diseases or conditions (for example, people with diabetes). Some laxatives may have negative side effects if taken over a long time. Laxatives are not recommended for weight loss.
Neck Pain (Cervical Pain)
Neck pain (cervical pain) may be caused by any number of disorders and diseases. Tenderness is another symptom of neck pain. Though treatment for neck pain really depends upon the cause, treatment typically may involve heat/ice application, traction, physical therapy, cortisone injection, topical anesthetic creams, and muscle relaxants.
Constipation is defined medically as fewer than three stools per week and severe constipation as less than one stool per week. Constipation usually is caused by the slow movement of stool through the colon. There are many causes of constipation including medications, poor bowel habits, low fiber diets, laxative abuse, and hormonal disorders, and diseases primarily of other parts of the body that also affect the colon.
Acute injuries, medical conditions, and chronic use conditions are causes of knee pain. Symptoms and signs that accompany knee pain include redness, swelling, difficulty walking, and locking of the knee. To diagnose knee pain, a physician will perform a physical exam and also may order X-rays, arthrocentesis, blood tests, or a CT scan or MRI. Treatment of knee pain depends upon the cause of the pain.
Bone cancer is a rare type of cancer that occurs in cells that make up the bones. Primary bone cancer that arises in bone cells is different than metastatic bone cancer, which is cancer that arises in another part of the body and then spreads to the bones. Hereditary and environmental factors likely contribute to the risk of bone cancer. Signs and symptoms of bone cancer may include pain, the presence of a mass or lump, and bone fractures. There are different types of bone cancer (osteosarcoma, chondrosarcoma, Ewing's sarcoma, pleomorphic sarcoma, fibrosarcoma). Treatment for bone cancer may include surgical removal of the tumor, chemotherapy, radiation, and/or a stem cell transplant. The prognosis for bone cancer depends on the type of cancer and the extent of spread.
Torn ACL (Anterior Cruciate Ligament Tear)
The anterior cruciate ligament helps to prevent the top and bottom of the knee from sliding back and forth. Symptoms and signs of a torn ACL include knee pain and swelling. Treatment of a torn ACL depends upon the health of the patient and the patient's expectations and willingness to undertake extensive physical therapy. Rehabilitation after surgical repair of an ACL tear may take more than nine months.
Arthritis, bursitis, IT band syndrome, fracture, and strain are just some of the causes of hip pain. Associated symptoms and signs include swelling, tenderness, difficulty sleeping on the hip, and loss of range of motion of the hip. Treatment depends upon the cause of the hip pain but may include anti-inflammatory medications and icing and resting the hip joint.
The shoulder is the most often dislocated joint in the body due to its mobility. Dislocation occurs when the head of the humerus is dislocated from its socket. Symptoms and signs of a shoulder dislocation include nausea and vomiting, lightheadedness, weakness, and sweating. There are various methods of reducing a dislocation and returning the humeral head to its normal place. The method for reduction of a shoulder dislocation depends upon the type of dislocation, the patient, the situation, and the clinician's experience. Intravenous narcotics and muscle relaxants are often administered to relax the muscles and relieve pain.
Pain management and treatment can be simple or complex, according to its cause. There are two basic types of pain, nociceptive pain and neuropathic pain. Some causes of neuropathic pain include: complex regional pain syndrome, interstitial cystitis, and irritable bowel syndrome. There are a variety of methods to treat chronic pain, which are dependant on the type of pain experienced.
Chronic pain is pain (an unpleasant sense of discomfort) that persists or progresses over a long period of time. In contrast to acute pain that arises suddenly in response to a specific injury and is usually treatable, chronic pain persists over time and is often resistant to medical treatments.
Drug addiction is a chronic disease that causes drug-seeking behavior and drug use despite negative consequences to the user and those around him. Though the initial decision to use drugs is voluntary, changes in the brain caused by repeated drug abuse can affect a person's self-control and ability to make the right decisions and increase the urge to take drugs. Drug abuse and addiction are preventable.
Teen Drug Abuse
Drugs commonly abused by teens include tobacco products, marijuana, cold medications, inhalants, depressants, stimulants, narcotics, hallucinogens, PCP, ketamine, Ecstasy, and anabolic steroids. Some of the symptoms and warning signs of teen drug abuse include reddened whites of eyes, paranoia, sleepiness, excessive happiness, seizures, memory loss, increased appetite, discolored fingertips, lips or teeth, and irritability. Treatment of drug addiction may involve a combination of medication, individual, and familial interventions.
Cancer pain results from the tumor pressing on nerves or invading bones or organs. Cancer treatments like chemotherapy, radiation, or surgery can also cause pain.
