Anodyne Therapy and Dextromethorphan

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Dextromethorphan and Anodyne Therapy in our sources. This does not guarantee that the combination is completely free of risk — research on Anodyne Therapy alongside specific medications may be limited.

Worth understanding: our licensed dataset holds no drug-interaction record for Anodyne Therapy at all — not against Dextromethorphan, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

Anodyne Therapy is a treatment rather than something you take. Tell whoever provides it which medicines you use, and ask your prescriber whether it is appropriate for your health and treatment. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Anodyne Therapy safety at a glance

Anodyne Therapy overall Use caution Generally considered low-risk when used as directed, but benefit is uncertain and burns are possible if used improperly.
Pregnancy Not established There is little data on use during pregnancy, so check with your doctor before use.
Breastfeeding Not established There is little data on use while breastfeeding, so check with your doctor before use.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

From our pharmacist’s overview on the Dextromethorphan page

“A glass of grapefruit juice can push dextromethorphan (Benylin, Hold, and other cough medicines) to higher levels than intended, one of four major-rated entries among the 171 supplements and herbs on file, and the list as a whole warrants real care. Most interactions trace back to the liver enzymes (CYP3A4 and CYP2D6) that clear dextro…”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Anodyne Therapy is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Anodyne Therapy reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Anodyne Therapy and Dextromethorphan records this page draws on were last updated July 11, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Anodyne Therapy

What is Anodyne Therapy?

  • Peripheral neuropathy symptoms
  • Numbness and tingling in feet
  • Diabetic nerve discomfort
  • Chronic pain and stiffness
  • Improving local blood flow
  • Balance and fall prevention concerns

Anodyne Therapy is not a herb or dietary supplement — it is a brand of infrared light therapy used mainly for nerve-related symptoms such as numbness, tingling, and pain. The evidence for lasting benefit is mixed and limited, and major reviews have not consistently shown that it improves true sensation or long-term outcomes. If you are considering it, talk with your doctor or pharmacist first.

Not applicable (it is a medical device therapy, not a plant or supplement) · In-office or home infrared light therapy devices (pads with infrared diodes)

An interaction check asks whether these two react with each other — it does not ask whether Anodyne Therapy is a good idea for someone in your situation. Here is what our Anodyne Therapy record says about it on its own.

Anodyne Therapy: dosing

There is no standardized, proven dose for Anodyne Therapy. Treatment sessions are typically described as lasting some minutes at a time, often repeated over several sessions, but specific protocols vary by device and provider.Follow the instructions that come with your device exactly, especially time and temperature limits, to lower the risk of burns. A physical therapist, pharmacist, or doctor can help you decide whether and how to use it. Do not assume "more is better."

About Dextromethorphan

What Is Dextromethorphan Used For?

Brand names: Hold, Benylin Adult, Benylin Pediatric, Theraflu Thin Strips Long Acting Cough, Neo Citran Thin Strips Cough

Dextromethorphan temporarily relieves cough due to minor throat and bronchial irritation, such as the kind that comes with the common cold or breathing in irritants. It also helps reduce the urge to cough so you — or your child — can get to sleep.

Some products, including CVS Long Acting Cough and Premier Value Tussin Cough oral liquids, are also indicated to help loosen phlegm (mucus) and thin bronchial secretions to help drain the airways.
