Securinega Suffruticosa and methylphenidate transdermal system

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

Moderate

STIMULANT DRUGS

Why this applies to methylphenidate transdermal system

methylphenidate transdermal system falls under STIMULANT DRUGS — the group Securinega Suffruticosa interacts with.

Theoretically, taking Securinega suffruticosa with stimulant drugs might increase the risk of serious adverse effects.
Securinega suffruticosa contains the alkaloid securinine. Animal research shows that securinine has CNS stimulating 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: the Daytrana patch already revs up your nervous system to help with focus and attention. Securinega suffruticosa contains an alkaloid called securinine that, in animal studies, also stimulates the nervous system. Stack two stimulating things together and you may get too much of the same effect.

What that could look like with methylphenidate is a faster or pounding heartbeat, higher blood pressure, jitteriness, trouble sleeping, anxiety, or feeling wired. I'll be honest, this concern is theoretical, based on how securinine behaves rather than real-world reports with the patch. Even so, securinine itself can be risky and has been linked to seizures, so this plant isn't a safe self-care choice. Please check with your doctor or pharmacist before combining them.

From our pharmacist’s overview on the methylphenidate transdermal system page

“Daytrana, the methylphenidate skin patch for ADHD, is itself a stimulant, and that shapes nearly this whole list, which I read as one that calls for real care. Of the 68 supplement ingredients on file, 44 are stimulants too, so pairing them can push heart rate and blood pressure higher than either alone.”

About Securinega Suffruticosa

What is Securinega Suffruticosa?

  • Nerve and muscle weakness
  • Fatigue and low energy
  • Nerve-related conditions in traditional medicine
  • Childhood paralysis (historical traditional use)
  • General tonic

Securinega suffruticosa is a shrub used in traditional East Asian medicine, best known for an alkaloid called securinine that strongly stimulates the nervous system. Because securinine is powerful and can cause seizures and serious toxicity, this plant is not a safe or well-studied dietary supplement, and it should not be used for self-treatment. Talk to a doctor or pharmacist before considering anything containing this plant.

About Methylphenidate Transdermal Patch

What Is Methylphenidate Transdermal Patch Used For?

Brand name: Daytrana

Methylphenidate Transdermal System — available as Daytrana and Methylphenidate Transdermal System — is approved to treat Attention Deficit Hyperactivity Disorder (ADHD) in pediatric patients ages 6 to 17 years.

It is not recommended for children under 6, because younger patients had higher drug exposure in the body and a higher rate of side effects such as weight loss compared to older children at the same dose.
