The bottom line No known interaction

We found no known interaction between Histidine 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.

Histidine 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 Histidine 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 Histidine 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.

What to actually watch for

What Dolutegravir’s Own FDA Label Lists

This is not an interaction — none of it involves Histidine. These are the most notable effects listed in the ADVERSE REACTIONS section of Dolutegravir’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 take both. 2 of them are worth acting on rather than waiting out — marked below.

  • Liver problems Worth acting on
  • An allergic reaction Worth acting on
  • Trouble sleeping
  • Tiredness mentioned in 5.4% of FDA reports for Dolutegravir
  • Headache mentioned in 4.6% of FDA reports for Dolutegravir
  • A skin rash

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

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.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Histidine 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 Histidine reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Histidine and Dolutegravir records this page draws on were last updated June 22, 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 Histidine

What is Histidine?

  • Skin conditions like eczema
  • Anemia related to kidney disease
  • Allergy and inflammation support
  • General amino acid supplementation
  • Athletic and protein supplementation

Histidine is an essential amino acid your body needs to build proteins and to make compounds like histamine and carnosine. Most people get enough from a normal diet, and good-quality research supporting histidine supplements for specific health conditions is limited. If you are considering a supplement, talk with a pharmacist or doctor first.

Amino acid (typically made commercially through fermentation) · Capsules, tablets, powder, part of amino acid blends and protein supplements

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

Histidine: dosing

There is no well-established standard supplement dose of histidine for treating health conditions. Amounts used in research have varied widely depending on the purpose.If you choose to use a histidine product, follow the directions on the label and do not exceed the recommended amount.

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.

Emotional distress 1,748 reports
Anhedonia 1,579 reports
