The bottom line No known interaction

We found no known interaction between Histidine and Tazarotene 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 Tazarotene

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 Tazarotene 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 Tazarotene, 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 Tazarotene’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 Tazarotene’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.

  • Hives Worth acting on
  • Bleeding or bruising Worth acting on
  • Dry skin mentioned in 6.3% of FDA reports for Tazarotene
  • Acne
  • Sun sensitivity
  • Itching mentioned in 5.8% of FDA reports for Tazarotene
  • Swelling
  • A skin rash mentioned in 5.4% of FDA reports for Tazarotene

From the ADVERSE REACTIONS section of the FDA label for Tazarotene. Read the label on DailyMed › Where a percentage is shown, it is the share of 1,342 voluntary FDA FAERS reports for Tazarotene 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.

See Every Supplement That Interacts With Tazarotene

This page covers Histidine only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Tazarotene page lists 24 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Vitamin A (major), Alfalfa (moderate), Angelica Archangelica (moderate), Arrach (moderate) and Bergamot (moderate).

By severity: 1 major · 21 moderate · 2 minor.

From our pharmacist’s overview on the Tazarotene page

“Tazarotene (Fabior, Arazlo) is a topical retinoid, a vitamin A relative prescribed for acne and psoriasis, and its supplement list deserves genuine attention. The one major-rated entry is vitamin A itself.”

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).

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 Tazarotene Topical

What Is Tazarotene Topical Used For?

Brand names: Avage, Tazorotene, Zorac, Fabior, Arazlo

Tazarotene cream 0.1% is used as part of a broader skin care routine to help lessen the look of fine facial wrinkles, mottled skin discoloration (uneven patches of lighter or darker skin), and benign facial lentigines (age spots or flat brown spots on the face). It is meant to be used alongside sun protection and a comprehensive skin care program.

It's important to know what tazarotene cream cannot do: it does not eliminate or prevent wrinkles, restore more youthful-looking skin, reverse sun damage, or repair photoaged skin. It has not been proven safe or effective for treating precancerous lesions (actinic keratoses) or skin cancers. Tazarotene gel formulations are also used for plaque psoriasis and acne vulgaris.
