Dilaudid vs Morphine Comparison

Dilaudid vs. Morphine: What’s the Difference?

Dilaudid (hydromorphone) and morphine are both prescription drugs that treat moderate to severe chronic pain. They belong to a class of drugs called opioid analgesics.⁵ These prescription opioids affect the brain by changing how your body feels and reacts to pain.

While hydromorphone is often mistaken as the generic name for morphine, both are different.¹²

Sixty-two percent of the time these drugs are mixed up, morphine is prescribed but hydromorphone is given in error.¹²

Doctors are prescribing morphine less often, while hydromorphone is increasing in medical and surgical situations.⁴

The main difference is that hydromorphone is stronger, so people need less of it to achieve the same pain-relieving effects. But both drugs are potent opioids for pain management that should be consumed with caution.

Here’s what you should know about them.

What is Dilaudid?

Dilaudid (hydromorphone) is a prescription medication made from morphine. ² Doctors, especially in hospital settings, prescribe it to some people for pain relief.⁷

Dilaudid binds to opioid receptors in the central nervous system. It works by activating reward centers in the brain and releasing endorphins. This camouflages your perception of pain.¹¹

The most common brand names of hydromorphone include Dilaudid and the following:⁷

• Dilaudid-5
• Exalgo
• Palladone

There are different forms of hydromorphone. It comes in IV (injection) liquid form, tablets, and extended-release capsules.⁷

Generally, hydromorphone in liquid form is consumed every 3 to 6 hours. Tablets are usually taken every four to 6 hours. Extended-release capsules are typically taken once daily around the same time. Your doctor will prescribe the right dose for you.⁷ Never take it more often than prescribed.

What are the side effects of Dilaudid?

The side effects of Dilaudid vary from person to person. They may include, but aren’t limited to, the following:⁷

• Headache
• Dizziness
• Lightheadedness
• Exhaustion
• Difficulty falling or staying asleep
• Drowsiness
• Sweating
• Muscle or joint pain
• Back pain
• Stomach pain
• Anxiety
• Depression
• Flushing
• Itchiness
• Rash or hives
• Swelling of the eyes, face, mouth, or throat
• Swelling of the arms, hands, feet, ankles, or lower legs
• Nausea with or without vomiting
• Erectile dysfunction
• Changes in menstruation
• Low libido
• Fainting
• Seizures
• Sedation

• Serious and potentially life-threatening breathing issues

Call your healthcare provider if you’re taking Dilaudid and experience trouble breathing. This includes slowed breathing, shortness of breath, and long pauses between breaths.

You should let your doctor know if you have or had asthma or a lung disease that can complicate breathing. You should notify your doctor about any of the following conditions before taking Dilaudid, as well as:⁷

• Head injury (any injury that ups the pressure in the brain) 
• Brain tumor
• Kyphoscoliosis (a condition characterized by the curving of the spine, which can cause breathing problems)
• Malnourishment

Certain medications can interact with Dilaudid. Talk to your doctor if you’re also taking any of the following:⁷

• Temazepam (Restoril)
• Triazolam (Halcion)
• Medications for a mental illness
• Medications for nausea
• Other narcotic pain medications
• Muscle relaxants
• Sedatives or sleeping pills
• Tranquilizers

You also shouldn’t drink alcohol while taking Dilaudid. Drinking alcohol while taking this prescription medication increases your risk of life-threatening side effects.⁷

You can report any other side effects you experience to the Federal Drug Administration (FDA) at 1-800-FDA-1088 or online at dailymed.nlm.nih.gov.¹
