Alpinia + Alpelisib

Alpelisib brand name: Piqray.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Alpinia and Alpelisib 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 label for Alpelisib states a food rule worth keeping to.

Alpinia and Alpelisib

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 Alpelisib and Alpinia 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.

Alpinia safety at a glance

Alpinia overall Use caution Generally well tolerated as a food, but supplement-level safety is not well studied.
Pregnancy Avoid Not enough safety data, so avoid medicinal amounts during pregnancy.
Breastfeeding Avoid Lack of safety data means it is best avoided in supplement form while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Alpelisib

Interactions in our licensed database are recorded against drug classes, not just single drug names. Alpelisib is filed under 3 classifications — cytochrome p450 2c9 (cyp2c9) inducers, cytochrome p450 3a4 (cyp3a4) substrates, oral drugs. Alpinia has documented interactions with 4 drug classes — the most serious being antacids (minor), h2-blockers (minor) and indomethacin (tivorbex) (minor) — and none of Alpelisib’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 Alpelisib’s Own FDA Label Lists

This is not an interaction — none of it involves Alpinia. These are the most notable effects listed in the ADVERSE REACTIONS section of Alpelisib’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. 8 of them are worth acting on rather than waiting out — marked below.

  • High blood sugar Worth acting on
  • A severe skin reaction Worth acting on
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on
  • Anemia Worth acting on
  • A severe allergic reaction Worth acting on
  • A higher chance of infection Worth acting on
  • An allergic reaction Worth acting on
  • Dry skin
  • A change in taste

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

How to take them

Some Alpelisib Products Have a Food Rule — Alpinia Should Not Break It

At least one FDA label for a product containing Alpelisib says to take it with food. If you take Alpinia on an empty stomach out of habit, keep them separate — and take Alpelisib with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Alpelisib products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

2 DOSAGE AND ADMINISTRATION Recommended Dose: Pediatric patients (2 to less than 18 years of age): 50 mg taken orally once daily with food.

From the Dosage and Administration section of the FDA label we read for Alpelisib — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

See Every Supplement That Interacts With Alpelisib

The most serious there right now: Activated Charcoal (major), Grapefruit (major), St. John's Wort (major), Acacia Rigidula (moderate) and Adrafinil (moderate).

By severity: 3 major · 96 moderate · 40 minor.

From our pharmacist’s overview on the Alpelisib page

“Alpelisib (Piqray) treats PIK3CA-mutated breast cancer, and a drug doing that job leaves little room for supplements that shift its blood level. Yet that is what most of this list does: 121 of the 139 ingredients on file can raise or lower alpelisib through CYP3A4, the liver enzyme that clears it.”

About Alpinia

What is Alpinia?

Alpinia
  • Digestive upset and bloating
  • Nausea
  • Anti-inflammatory support
  • Respiratory and cough complaints
  • Antimicrobial
  • Appetite stimulant

Alpinia (lesser galangal) is a ginger-family root long used in Asian cooking and traditional medicine, mainly for digestive and inflammatory complaints. Most of its proposed health benefits come from laboratory and animal studies, and strong human evidence is lacking. Food amounts are generally well tolerated, but talk with your pharmacist or doctor before using concentrated supplements.

Alpinia officinarum · Zingiberaceae · Rhizome (root) · Dried rhizome, powder, capsules, tea, tincture, essential oil, culinary spice

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

Alpinia: dosing

There is no standardized, well-established medicinal dose for Alpinia. Amounts used in traditional medicine and supplements vary widely depending on the form, whether it is a tea, powder, capsule, or tincture.The safest approach is to follow the directions on the product label and not exceed the recommended amount. They can help you decide if it is appropriate and how much is reasonable.

About Alpelisib

What Is Alpelisib Used For?

Brand name: Piqray

Alpelisib is approved for two distinct uses, each tied to a specific brand. Piqray is used in combination with another drug called fulvestrant to treat adults with hormone receptor (HR)-positive, HER2-negative, advanced or metastatic breast cancer whose tumors carry a PIK3CA mutation — and only after the cancer has progressed on or after a hormone-based treatment. A companion diagnostic test is required before starting Piqray.

Vijoice is used to treat adults and children 2 years of age and older who have severe manifestations of PIK3CA-Related Overgrowth Spectrum (PROS) — a rare condition where PIK3CA gene mutations cause abnormal tissue, vascular, and bone overgrowth — and who need systemic (whole-body) therapy. Vijoice's approval for PROS was granted under the FDA's accelerated approval pathway based on response data, and continued approval may depend on confirmatory trials.

Taking Alpinia and Alpelisib Together: Common Questions

Is it safe to take Alpinia with Alpelisib?
We do not list a known interaction between Alpinia and Alpelisib. 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.
Should I take Alpinia and Alpelisib at the same time of day?
At least one FDA label for a product containing Alpelisib says to take it with food. If you take Alpinia on an empty stomach out of habit, keep them separate and take Alpelisib with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Alpelisib products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Alpinia and Alpelisib combination checked?
Interactions in our licensed database are recorded against drug classes. Alpelisib is filed under 3 classifications, and Alpinia has documented interactions with 4 drug classes — none of Alpelisib's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Alpinia interact with any other medications?
Yes. Alpinia has 37 documented drug interactions in our database — Alpelisib is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Alpelisib interact with any supplements?
Yes. Alpelisib has documented interactions with 139 supplements in our database — Alpinia is not one of them. The Alpelisib interaction page linked on this page lists every one, ranked by severity.
