Saffron and Hydromorphone

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

Moderate

CNS DEPRESSANTS

Why this applies to Hydromorphone

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

Theoretically, concomitant use of saffron and CNS depressants might have additive sedative effects.
Clinical research shows that taking saffron extract 60 mg orally daily for 26 weeks can cause drowsiness and sedation. Animal research suggests that adding saffron to hexobarbital further increases sleeping and slows motor activity.
Severity Moderate 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

Here's the thing to keep in mind: hydromorphone is a strong opioid that already slows down your brain and body. It can make you feel drowsy, foggy, or slow to react, and at higher doses it can slow your breathing. Saffron, especially in concentrated supplement doses, has been shown to cause some drowsiness and sedation of its own. Put the two together and those calming, sleepy effects could simply stack on top of each other.

I want to be honest about how solid this is. This warning is theoretical, based on how each one acts and on early studies and animal research, not on strong human proof. A pinch of saffron in your cooking is very unlikely to matter. A daily saffron supplement is the bigger question. Please check with your pharmacist or doctor before pairing them, and watch for extra sleepiness or trouble concentrating.

“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 Saffron

What is Saffron?

Saffron
  • Depression and low mood
  • Anxiety
  • PMS symptoms
  • Memory and cognition
  • Eye health (age-related macular degeneration)

Saffron is a costly spice that has shown promise in early studies for mild-to-moderate depression and some mood and PMS symptoms, but most research uses small trials, so results are not definitive. It is generally well tolerated in food and small supplement amounts, but high doses can be harmful and it should be avoided in pregnancy. Talk to your pharmacist or doctor before using saffron supplements.

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.
