Drug & supplement interaction

Oscillococcinum + Dolutegravir

Dolutegravir brand name: Tivicay.

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 Oscillococcinum and Dolutegravir 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.

Oscillococcinum and Dolutegravir

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 Dolutegravir and Oscillococcinum 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.

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

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.

Oscillococcinum safety at a glance

Oscillococcinum overall Use caution Generally well tolerated, but evidence of benefit is lacking and it should not replace proven flu care.
Pregnancy Use caution Safety has not been well studied in pregnancy, so check with your doctor first.
Breastfeeding Use caution Little data exists during breastfeeding, so use only with medical guidance.

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

What to actually watch for

No Interaction Found — But Data Suggests Oscillococcinum and Dolutegravir May Share a Side Effect

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.

  • Headache reported in 4.6% of FDA reports for Dolutegravir Additional detail

    Dolutegravir

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

Reported for Oscillococcinum but not commonly for Dolutegravir: a severe allergic reaction.

Effects for Dolutegravir come from the ADVERSE REACTIONS section of its FDA label; effects for Oscillococcinum come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 19,465 voluntary FDA FAERS reports for Dolutegravir 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.

Everything else you take

See Every Supplement That Interacts With Dolutegravir

This page covers Oscillococcinum only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Dolutegravir page lists 65 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Calcium (major), St. John's Wort (major), Bitter Melon (moderate) and Black Pepper (moderate).

By severity: 3 major · 46 moderate · 16 minor.

From our pharmacist’s overview on the Dolutegravir page

“Dolutegravir (Tivicay) works only when its blood level stays high enough to keep HIV suppressed, so a supplement that drags that level down can let the virus rebound, and this list warrants genuine care. Three of the 65 entries are rated major.”

About Oscillococcinum

What is Oscillococcinum?

  • Flu-like symptoms
  • Common cold symptoms
  • Body aches and chills
  • Fatigue during illness
  • Fever associated with the flu

Oscillococcinum is a homeopathic product made from extremely diluted duck liver and heart, marketed to ease flu-like symptoms. High-quality research has not shown it works better than a placebo, but it is generally well tolerated. If you choose to try it, see it as a low-risk option rather than a proven treatment, and don't use it to replace a flu vaccine or needed medical care.

Anas barbariae hepatis et cordis extractum · Highly diluted extract of duck liver and heart (Muscovy duck) · Oral pellets/granules that dissolve under the tongue

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

Oscillococcinum: dosing

There is no scientifically established effective dose for Oscillococcinum, since it has not been shown to work. If you choose to use it, follow the directions on the product label exactly.The pellets are typically dissolved under the tongue rather than swallowed with water, and packages often suggest starting at the first sign of symptoms.

About Dolutegravir

What Is Dolutegravir Used For?

Brand name: Tivicay

Tivicay and Tivicay PD are used to treat HIV-1 infection. They are always taken in combination with other antiretroviral medicines — they are not used alone. Both products are approved for adults (whether new to treatment or previously treated) and for children who have not previously been treated with an integrase inhibitor (INSTI).

Tivicay (the standard tablet) has an additional use: it can be combined with rilpivirine as a complete two-drug regimen for adults whose HIV is already well controlled (virologically suppressed) on a stable treatment plan for at least 6 months, with no history of treatment failure or known resistance to either drug.

Most-Reported Side Effects for Dolutegravir

From FAERS, the FDA’s public side-effect reporting system (19,465 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Anxiety 1,892 reports
Emotional distress 1,748 reports
Anhedonia 1,579 reports
Chronic kidney disease 1,161 reports
Fatigue 1,057 reports

Taking Oscillococcinum and Dolutegravir Together: Common Questions

Is it safe to take Oscillococcinum with Dolutegravir?
We do not list a known interaction between Oscillococcinum and Dolutegravir. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Oscillococcinum and Dolutegravir have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Does Dolutegravir interact with any supplements?
Yes. Dolutegravir has documented interactions with 65 supplements in our database — Oscillococcinum is not one of them. The Dolutegravir interaction page linked on this page lists every one, ranked by severity.
