Applied Kinesiology and Valacyclovir

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 Valacyclovir and Applied Kinesiology in our sources. This does not guarantee that the combination is completely free of risk — research on Applied Kinesiology alongside specific medications may be limited.

Worth understanding: our licensed dataset holds no drug-interaction record for Applied Kinesiology at all — not against Valacyclovir, 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.

Applied Kinesiology 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.

Applied Kinesiology safety at a glance

Applied Kinesiolog... overall Use caution The muscle testing itself is low-risk, but relying on it instead of proper diagnosis can be harmful.
Pregnancy Use caution Avoid using it to guide health decisions during pregnancy; rely on standard prenatal care.
Breastfeeding Use caution Do not use it to replace proper medical evaluation while breastfeeding.

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

What Valacyclovir’s Own FDA Label Lists

This is not an interaction — none of it involves Applied Kinesiology. These are the most notable effects listed in the ADVERSE REACTIONS section of Valacyclovir’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you have Applied Kinesiology and take the medicine. 10 of them are worth acting on rather than waiting out — marked below.

  • Mania or an unusually elevated mood Worth acting on
  • Dehydration Worth acting on
  • Unsteadiness Worth acting on
  • Hallucinations Worth acting on
  • Confusion Worth acting on
  • A severe skin reaction Worth acting on
  • Seizures Worth acting on
  • Low mood Worth acting on
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Valacyclovir. Read the label on DailyMed › Applied Kinesiology’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Applied Kinesiology side to compare — that is a limit of the record, not a statement that Applied Kinesiology has no side effects.

Everything else you take

See Every Supplement That Interacts With Valacyclovir

This page covers Applied Kinesiology only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Valacyclovir page lists 27 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), African Wild Potato (moderate), Banderol (moderate), Biofeedback (moderate) and Caffeic Acid (moderate).

By severity: 1 major · 17 moderate · 9 minor.

From our pharmacist’s overview on the Valacyclovir page

“Valacyclovir (Valtrex) works against herpes outbreaks only if enough of it gets absorbed into your blood, and most of this list threatens exactly that. Of the 27 supplements on file, 17 can change how well oral medicines like this one are absorbed, and the single major-rated entry, activated charcoal, binds drugs in the gut outright.”

About Applied Kinesiology

What is Applied Kinesiology?

  • Diagnosing food sensitivities or allergies
  • Detecting nutrient deficiencies
  • Identifying which supplements to take
  • Finding the cause of pain or illness
  • Choosing alternative therapies

Applied Kinesiology is not a herb or supplement — it is an alternative diagnostic method that uses manual muscle testing to supposedly find health problems or pick treatments. Scientific studies have not shown it to be a reliable or accurate way to diagnose disease, food allergies, or nutrient needs, so it should not replace standard medical testing. If you have health concerns, talk with your doctor or pharmacist and use proven diagnostic tools.

Diagnostic technique performed by a practitioner (not a supplement or product)

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

Applied Kinesiology: dosing

There is no "dose" for Applied Kinesiology because it is a diagnostic technique, not a substance you take. There is no standardized, validated protocol that produces reliable results.If Applied Kinesiology is used to recommend specific supplements, do not assume those recommendations are accurate.

About Valacyclovir

What Is Valacyclovir Used For?

Brand name: Valtrex

Valacyclovir tablets are used in adults to treat cold sores (herpes labialis), genital herpes (initial and recurrent episodes), and shingles (herpes zoster). They can also be taken daily as suppressive therapy to reduce how often genital herpes outbreaks occur, and to lower the risk of passing genital herpes to a partner.

In children and adolescents, valacyclovir tablets are used to treat cold sores in those aged 12 and older, and chickenpox in those aged 2 to under 18. Valacyclovir has not been established as safe and effective for most uses in immunocompromised patients, with the exception of suppressive therapy for genital herpes in HIV-infected adults.

Most-Reported Side Effects for Valacyclovir

From FAERS, the FDA’s public side-effect reporting system (70,056 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 4,317 reports
Nausea 3,985 reports
Diarrhea 3,648 reports
