Rhodiola and Hydromorphone

Here is the interaction we found between these two, with the evidence behind it.

Minor

CNS DEPRESSANTS

Why this applies to Hydromorphone

Hydromorphone falls under CNS DEPRESSANTS — the group Rhodiola interacts with.

Theoretically, rhodiola might increase the risk of adverse effects when taken with CNS depressants.
A review of adverse event reports in Poland identified cases of excessive sedation, myoclonus, hypotension, and hallucinations when rhodiola was taken with haloperidol, diazepam, or alprazolam.
Severity Minor Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Hydromorphone is a strong opioid pain reliever that already slows down the brain and body, causing things like drowsiness, slowed breathing, low blood pressure, and confusion. Rhodiola is grouped here with other central nervous system depressants, and the concern is simply that stacking it on top of hydromorphone could, in theory, add to that sedating effect.

I want to be honest about the evidence: this is mostly theoretical and based on a handful of anecdotal reports involving other drugs (like diazepam and haloperidol), not hydromorphone specifically. Rhodiola does not appear to change how your body breaks the drug down. Still, since hydromorphone is powerful, it's worth mentioning Rhodiola to your pharmacist or doctor before combining them, and watch for extra sleepiness or feeling foggy.

“Hydromorphone (Dilaudid, Palladone) is a potent opioid, and the risk that matters most with any opioid is slowed breathing. Most of this list pushes in exactly that direction.”

About Rhodiola

What is Rhodiola?

Rhodiola
  • Fatigue and low energy
  • Stress and coping (adaptogen)
  • Mental performance and focus
  • Mild depression
  • Physical and exercise performance

Rhodiola is an herb traditionally used to fight fatigue and help the body cope with stress. Some small studies suggest it may modestly reduce fatigue and improve mood, but the evidence is limited and not strong. It is generally well tolerated for short-term use, but talk to your pharmacist or doctor before trying it, and avoid it during pregnancy and breastfeeding.

About Hydromorphone

What Is Hydromorphone Used For?

Brand names: Dilaudid, Hydromorph Contin, Palladone

Hydromorphone is used to manage pain severe enough to require an opioid analgesic — when non-opioid medicines or other options have not worked or are not expected to work well enough. It is available in several forms: oral tablets, oral solution, rectal suppositories, and injectable formulations given into a vein, muscle, or under the skin.

Hydromorphone hydrochloride extended-release tablets are specifically for severe, persistent pain that requires around-the-clock opioid treatment for an extended period, and are only for opioid-tolerant patients — they are not for as-needed use. The high-potency injectable formulation is also reserved for opioid-tolerant patients who need higher opioid doses.
