Corn Poppy and Pregabalin

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

Moderate

CNS DEPRESSANTS

Why this applies to Pregabalin

Pregabalin falls under CNS DEPRESSANTS — the group Corn Poppy interacts with.

Theoretically, concomitant use of corn poppy with CNS depressants might increase the risk of sedation.
Animal research suggests that corn poppy leaf extract has sedative effects.
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: pregabalin (Lyrica) already tends to make people feel drowsy, foggy, or a little off balance, especially when you first start it or bump up the dose. Corn poppy, based on animal studies, seems to have its own mild calming effect. Stack the two together and you could feel sleepier, more lightheaded, or slower to think than you'd expect from the pregabalin alone.

Keep in mind this is theoretical. The concern comes from lab and animal research, not solid human studies, and corn poppy's plant compounds are weak. So it's a possible, not a guaranteed, problem. Still, I'd mention it to your pharmacist or doctor before combining them, and don't drive or do anything risky until you know how the pair affects you.

From our pharmacist’s overview on the Pregabalin page

“Pregabalin (Lyrica) calms overactive nerves, which is how it eases nerve pain, seizures, and anxiety, and that calming action stacks with almost everything on this list. Of the 95 supplements and herbs, the large majority add their own sedation on top of pregabalin's, and a few can tip that into genuine danger, with deep sedation and s…”

About Corn Poppy

What is Corn Poppy?

Corn Poppy
  • Cough and sore throat
  • Sleep and restlessness
  • Mild pain
  • Anxiety and nervousness
  • Digestive complaints

Corn poppy is a red-flowered plant traditionally used in teas and syrups for cough, sleep, and mild pain. Solid human research is very limited, so its benefits are not well proven, and unlike its relative the opium poppy, it contains only small amounts of weak alkaloids. Talk to a pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

About Pregabalin

What Is Pregabalin Used For?

Brand names: Lyrica, Lyrica CR

Pregabalin is used to manage several types of nerve pain, including neuropathic pain from diabetic peripheral neuropathy (nerve damage caused by diabetes) and postherpetic neuralgia (lingering nerve pain after shingles). It is also used to treat fibromyalgia and neuropathic pain associated with spinal cord injury.

Lyrica (capsule and oral solution), pregabalin capsules, and pregabalin oral solution are also approved as add-on therapy for partial-onset seizures — Lyrica for patients 1 month and older, and pregabalin capsules for patients 17 years and older. Lyrica CR and pregabalin extended-release tablets are approved only for diabetic peripheral neuropathy pain and postherpetic neuralgia — their effectiveness for fibromyalgia or as seizure add-on therapy has not been established.
