Tyramine and Hethylphenidate HCl

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

Minor

STIMULANT DRUGS

Why this applies to Hethylphenidate HCl

Hethylphenidate HCl falls under STIMULANT DRUGS — the group Tyramine interacts with.

Theoretically, taking tyramine with stimulant drugs might increase the risk of adverse cardiovascular effects.
Tyramine is thought to have stimulant effects.
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

Methylphenidate (the active ingredient here) is a stimulant that already nudges up your heart rate and blood pressure. Tyramine, the natural compound in aged cheeses, cured meats, and fermented foods, can prompt your body to release norepinephrine, which does much the same thing. Stack the two and, at least in theory, you could get an additive bump in cardiovascular effects like a faster heartbeat, palpitations, or higher blood pressure.

The good news: this is a theoretical, minor concern based on how these substances work, not on strong real-world reports. Normal food amounts of tyramine are unlikely to cause trouble for most people on methylphenidate (unlike the serious risk with older MAO inhibitors). Still, if you notice racing heart or feel jittery, or you have heart or blood pressure issues, check in with your pharmacist or doctor.

About Tyramine

What is Tyramine?

  • Studied for effects on blood pressure
  • Discussed in relation to migraine and headache triggers
  • Of interest in food and diet science
  • Subject of research on the nervous system

Tyramine is a natural compound formed when certain proteins break down, and it is found in aged cheeses, cured meats, fermented foods, and some other items. It is not a typical health supplement and is best known for the problems it can cause—such as dangerous spikes in blood pressure—in people taking certain medications or in those who are sensitive to it. If you have been told to follow a low-tyramine diet, talk with your pharmacist or doctor before making changes.
