Drug & supplement interaction

Caprylic Acid + Cabotegravir Sodium

Cabotegravir Sodium brand name: Vocabria.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Caprylic Acid and Cabotegravir Sodium in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Caprylic Acid and Cabotegravir Sodium

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 Cabotegravir Sodium and Caprylic Acid in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. 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.

Caprylic Acid safety at a glance

Caprylic Acid overall Use caution Generally recognized as safe in food, but supplement doses are less well studied.
Pregnancy Use caution Food amounts are likely fine, but supplement doses lack safety data, so avoid unless your doctor approves.
Breastfeeding Use caution Caprylic acid occurs naturally in breast milk, but concentrated supplement safety is unknown, so use caution.

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

How we checked

Why No Interaction Is Listed for Cabotegravir Sodium

Interactions in our licensed database are recorded against drug classes, not just single drug names. Cabotegravir Sodium is filed under 2 classifications — glucuronidated drugs, oral drugs. Caprylic Acid has documented interactions with 3 drug classes — the most serious being antihypertensive drugs (moderate), nonsteroidal anti-inflammatory drugs (nsaids) (moderate) and warfarin (coumadin) (moderate) — and none of Cabotegravir Sodium’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Caprylic Acid and Cabotegravir Sodium May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Tiredness / Dizziness / Headache reported in 3.6% of FDA reports for Cabotegravir Sodium Additional detail

    “Orally, caprylic acid has rarely been reported to cause mild dizziness, headache, and fatigue.”

    Cabotegravir Sodium

    Listed in the ADVERSE REACTIONS section of the FDA label for Cabotegravir Sodium, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Caprylic Acid but not commonly for Cabotegravir Sodium: stomach upset and a change in taste.

Effects for Cabotegravir Sodium come from the ADVERSE REACTIONS section of its FDA label; effects for Caprylic Acid come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 1,558 voluntary FDA FAERS reports for Cabotegravir Sodium that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

“Cabotegravir (Vocabria) is an HIV medicine, and keeping its blood level steady is what keeps the virus suppressed, so I read this list of 29 interacting supplements with genuine concern. The one major entry is activated charcoal, a popular detox remedy that soaks up drugs in the gut and cuts how much reaches you.”

About Caprylic Acid

What is Caprylic Acid?

Caprylic Acid
  • Candida and yeast overgrowth
  • Gut health support
  • Antimicrobial
  • Digestive health
  • Part of ketogenic diets

Caprylic acid is a medium-chain fatty acid found in coconut oil and palm kernel oil that is popularly used for yeast overgrowth and gut health. While laboratory studies show it has antimicrobial activity, strong human evidence for most supplement claims is limited. It is generally considered safe in food amounts, but talk with your pharmacist or doctor before using concentrated supplements.

Fatty acid derived from coconut and palm kernel oil; also found in milk fat · Capsules, softgels, liquid oil, part of MCT oil blends

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

Caprylic Acid: dosing

There is no official, well-established dose for caprylic acid as a supplement. Products vary widely in strength and form, so the right amount depends on the specific product.The safest approach is to follow the directions on the product label and start with a lower amount to see how your body responds.

About Cabotegravir

What Is Cabotegravir Used For?

Brand name: Vocabria

Vocabria (cabotegravir) tablets are used in combination with rilpivirine (Edurant) to treat HIV-1 infection in adults and adolescents aged 12 and older who weigh at least 35 kg and whose HIV is already virologically suppressed (virus levels undetectable or very low on their current regimen). Vocabria tablets serve as a short-term oral lead-in — taken for roughly one month — before switching to long-acting injectable therapy.

Cabotegravir tablets are also used as an oral lead-in for HIV-1 pre-exposure prophylaxis (PrEP) — helping HIV-negative adults and adolescents (weighing at least 35 kg) confirm they tolerate the drug before starting injectable PrEP. Both uses require confirmed HIV-negative status before starting.

Most-Reported Side Effects for Cabotegravir Sodium

From FAERS, the FDA’s public side-effect reporting system (1,558 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Viral load increased 109 reports
Injection site pain 105 reports
Virologic failure 64 reports
Hepatitis b 63 reports
Pathogen resistance 61 reports

How was the Caprylic Acid and Cabotegravir Sodium combination checked?

Cabotegravir Sodium is filed under 2 classifications, and Caprylic Acid has documented interactions with 3 drug classes — none of Cabotegravir Sodium's classifications are among them.
