Gotu Kola 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 Gotu Kola interacts with.

Theoretically, taking gotu kola might increase the sedative effects of CNS depressants.
In vitro research suggests that gotu kola may have sedative effects via binding of GABA receptors.
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 simple version: hydromorphone (Dilaudid) is a strong opioid pain reliever, and one of its biggest effects is making you drowsy and slowing your breathing. Gotu kola is thought to have a mild calming, sedating effect of its own, possibly by acting on the same GABA system in your brain that opioids quiet down. Put them together and, in theory, you could feel more sleepy, foggy, or dizzy than usual.

I want to be honest about the evidence here: this concern comes mostly from lab studies, not real patient reports, so it's considered theoretical. Still, because hydromorphone is already a powerful sedating medicine, it's worth mentioning to your pharmacist or doctor before adding gotu kola, especially if you notice extra grogginess.

From our pharmacist’s overview on the Hydromorphone page

“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 Gotu Kola

What is Gotu Kola?

Gotu Kola
  • Wound healing
  • Varicose veins and poor circulation
  • Anxiety and stress
  • Memory and mental clarity
  • Skin health and scarring

Gotu kola is a traditional Ayurvedic and Asian herb that people use for wound healing, circulation, skin problems, and as a calming or memory-supporting herb. Some early studies suggest possible benefits for vein health and skin, but the overall evidence is limited and not strong. Talk to your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have liver problems.

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.
