Biofeedback and hydrocortisone, lidocaine

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

Moderate

SEIZURE THRESHOLD LOWERING DRUGS

Why this applies to hydrocortisone, lidocaine

hydrocortisone, lidocaine falls under SEIZURE THRESHOLD LOWERING DRUGS — the group Biofeedback interacts with.

There is some concern that electroencephalogram (EEG) biofeedback might lower the seizure threshold in some patients. Theoretically, combining EEG biofeedback with seizure threshold-lowering drugs might increase the risk of seizure.
Some drugs that lower the seizure threshold include anesthetics (propofol, others), antiarrhythmics (mexiletine), antibiotics (amphotericin, penicillin, cephalosporins, imipenem), antidepressants (bupropion, others), antihistamines (cyproheptadine, others), immunosuppressants (cyclosporine), narcotics (fentanyl, others), stimulants (methylphenidate), theophylline, and others.
Severity Moderate Likelihood Possible Evidence B

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 explains PharmD, Clinical Pharmacist

This one is pretty mild in practice. The concern on file is that EEG biofeedback might slightly lower the seizure threshold, and lidocaine, when it builds up in the bloodstream, can do the same. So the theory is that pairing the two could very slightly raise seizure risk.

Here's the reassuring part: your AnaMantle HC or Lida-Mantle-HC cream is applied to the skin, usually for irritation or hemorrhoids. Very little lidocaine reaches your blood when used as directed on a small area, so a real-world interaction is unlikely. Just avoid using large amounts on broken skin, and if you have a seizure history, mention it to your pharmacist or doctor before combining them.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

From our pharmacist’s overview on the hydrocortisone, lidocaine page

“Hydrocortisone with lidocaine cream (AnaMantle HC, Lida-Mantle-HC) treats skin pain and irritation, and its nine supplement interactions sort into two patterns. Six, melatonin among them, might add to the seizure-threshold lowering that anesthetics like lidocaine already carry.”

About Biofeedback

What is Biofeedback?

  • Chronic pain
  • Headaches and migraines
  • Anxiety and stress
  • High blood pressure
  • Urinary incontinence
  • Tension and muscle relaxation

Biofeedback is a mind-body technique, not an herb or supplement. It uses sensors to show you real-time information about body functions like heart rate, muscle tension, or skin temperature so you can learn to control them. It is generally very safe and has reasonable evidence for headaches, certain pain conditions, and pelvic floor problems, but it works best alongside standard medical care.
