Drug & supplement interaction

Rice Protein + Alectinib Hydrochloride

Alectinib Hydrochloride brand name: Alecensa.

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 Rice Protein and Alectinib Hydrochloride 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 Alectinib Hydrochloride states a food rule worth keeping to, and 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.

Rice Protein and Alectinib Hydrochloride

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 Alectinib Hydrochloride and Rice Protein 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.

Rice Protein safety at a glance

Rice Protein overall Generally safe Rice protein is generally considered safe for most healthy adults when used as a food.
Pregnancy Use caution Whole food rice is fine, but concentrated supplements are not well studied in pregnancy, so check with your provider first.
Breastfeeding Use caution Likely fine as a food, but concentrated protein supplements are not well studied 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 Alectinib Hydrochloride

Interactions in our licensed database are recorded against drug classes, not just single drug names. Alectinib Hydrochloride is filed under 3 classifications — photosensitizing drugs, hepatotoxic drugs, oral drugs. Rice Protein has documented interactions with 1 drug class — the most serious being ace inhibitors (aceis) (moderate) — and none of Alectinib Hydrochloride’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 Rice Protein and Alectinib Hydrochloride 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 / Diarrhea / Vomiting reported in 7.1% of FDA reports for Alectinib Hydrochloride Additional detail

    Rice Protein

    “Orally, rice protein has been rarely reported to cause enterocolitis symptoms of vomiting, diarrhea, and dehydration, possibly leading to acidosis and lethargy, in infants and young children. Rarely, enterocolitis symptoms are associated with an allergy to rice protein.”

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

Reported for Rice Protein but not commonly for Alectinib Hydrochloride: dehydration.

Effects for Alectinib Hydrochloride come from the ADVERSE REACTIONS section of its FDA label; effects for Rice Protein come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 7,249 voluntary FDA FAERS reports for Alectinib Hydrochloride 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.

How to take them

Some Alectinib Hydrochloride Products Have a Food Rule — Rice Protein Should Not Break It

At least one FDA label for a product containing Alectinib Hydrochloride says to take it with food. If you take Rice Protein on an empty stomach out of habit, keep them separate — and take Alectinib Hydrochloride 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 Alectinib Hydrochloride 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.

Administer ALECENSA with food.

From the Dosage and Administration section of the FDA label we read for Alectinib Hydrochloride — 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.

From our pharmacist’s overview on the Alectinib Hydrochloride page

“Alectinib (Alecensa) treats ALK-positive lung cancer, and because your liver already has to tolerate this drug, check this page before adding any supplement, not after. Of the 74 ingredients on file, 38 can add stress to the liver, and three of the four major-rated entries (beer, wine, and Siberian cocklebur) are the clearest examples…”

About Rice Protein

What is Rice Protein?

  • Building and maintaining muscle
  • Post-workout recovery
  • Plant-based protein source
  • Meal replacement and shakes
  • Weight management support

Rice protein is a plant-based protein powder made from rice that offers an easy way to add protein to your diet, especially if you avoid dairy or animal products. It is generally considered safe and well tolerated, though on its own it is lower in the amino acid lysine and is often blended with pea protein for a more complete amino acid profile. Talk to your pharmacist or doctor before using it if you have kidney problems or other health conditions.

Oryza sativa · Poaceae · Seed (grain/endosperm and bran) · Powder, protein shakes, capsules, blended plant-protein products

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

Rice Protein: dosing

There is no official standardized dose for rice protein. Serving sizes are usually based on how much protein you want to add to your diet, commonly around 20 to 30 grams of protein per scoop, but this varies by product.Always follow the directions on the product label and consider your total daily protein needs from all foods.

Taking Rice Protein and Alectinib Hydrochloride Together: Common Questions

Is it safe to take Rice Protein with Alectinib Hydrochloride?
We do not list a known interaction between Rice Protein and Alectinib Hydrochloride. 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 Rice Protein and Alectinib Hydrochloride have any of the same side effects?
Yes — our sources link each of them separately to 3 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.
Should I take Rice Protein and Alectinib Hydrochloride at the same time of day?
At least one FDA label for a product containing Alectinib Hydrochloride says to take it with food. If you take Rice Protein on an empty stomach out of habit, keep them separate and take Alectinib Hydrochloride with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Alectinib Hydrochloride products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Rice Protein and Alectinib Hydrochloride combination checked?
Interactions in our licensed database are recorded against drug classes. Alectinib Hydrochloride is filed under 3 classifications, and Rice Protein has documented interactions with 1 drug class — none of Alectinib Hydrochloride'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 Rice Protein interact with any other medications?
Yes. Rice Protein has 23 documented drug interactions in our database — Alectinib Hydrochloride 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 Alectinib Hydrochloride interact with any supplements?
Yes. Alectinib Hydrochloride has documented interactions with 74 supplements in our database — Rice Protein is not one of them. The Alectinib Hydrochloride interaction page linked on this page lists every one, ranked by severity.
