Alkaline Diet and Apalutamide

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 Apalutamide and Alkaline Diet in our sources. This does not guarantee that the combination is completely free of risk — research on Alkaline Diet alongside specific medications may be limited.

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

Alkaline Diet is an eating pattern rather than something you take. Ask your pharmacist or doctor before changing how you eat while on a prescribed medicine: some medicines are dosed around meals, and a change in diet can change how they work. 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.

Alkaline Diet safety at a glance

Alkaline Diet overall Use caution Generally safe for healthy people, but very restrictive versions may lack key nutrients.
Pregnancy Use caution A balanced version may be fine, but restrictive forms could limit needed nutrients; check with your doctor.
Breastfeeding Use caution Make sure overall nutrition stays adequate; discuss with your healthcare provider.

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

What to actually watch for

What Apalutamide’s Own FDA Label Lists

This is not an interaction — none of it involves Alkaline Diet. These are the most notable effects listed in the ADVERSE REACTIONS section of Apalutamide’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 follow Alkaline Diet and take the medicine. 10 of them are worth acting on rather than waiting out — marked below.

  • A change in thyroid levels Worth acting on
  • A stroke or mini-stroke Worth acting on
  • Bone thinning Worth acting on
  • Trouble passing urine Worth acting on
  • High potassium Worth acting on
  • A heart attack Worth acting on
  • Heart failure Worth acting on
  • High blood sugar Worth acting on
  • A severe skin reaction Worth acting on
  • Seizures Worth acting on

Showing the 10 most notable of 30 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Apalutamide. Read the label on DailyMed › Where a percentage is shown, it is the share of 11,688 voluntary FDA FAERS reports for Apalutamide that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Alkaline Diet’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Alkaline Diet side to compare — that is a limit of the record, not a statement that Alkaline Diet has no side effects.

Overlapping uses

What Apalutamide Is Prescribed For, and What Alkaline Diet Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Apalutamide is a prescription medicine with approved uses on its FDA label. Alkaline Diet is an eating pattern: what follows is what researchers have looked at it for, and how strong that evidence is.

Apalutamide is prescribed for: Erleada (apalutamide) is used to treat two types of prostate cancer. The first is metastatic castration-sensitive prostate cancer (mCSPC) — prostate cancer that has spread to other parts of the body and still responds to hormone-lowering therapy. The second is non-metastatic castration-resistant prostate cancer (nmCRPC) — prostate cancer that has stopped responding to standard hormone therapy but has not yet spread to other organs. Erleada is always used alongside a gonadotropin-releasing hormone (GnRH) analog — a medicine that lowers testosterone — or in patients who have already had surgery to remove the testicles.

Alkaline Diet has been studied for:

  • Prostate cancer studied, not established Alkaline Diet has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Alkaline Diet for prostate cancer

    It is unclear if an alkaline diet is beneficial for the prevention of prostate cancer.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Apalutamide on your own; if you are taking Alkaline Diet for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

From our pharmacist’s overview on the Apalutamide page

“Apalutamide (Erleada) treats prostate cancer, and it only works when its blood level stays where it should, so approach this list with genuine care. Three of the 155 ingredients on file are rated major: grapefruit can push apalutamide levels up, St.”

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

What is Alkaline Diet?

  • General wellness
  • Bone health
  • Weight management
  • Kidney stone prevention
  • Reducing inflammation

The alkaline diet encourages eating more fruits and vegetables while cutting back on meat, dairy, and processed foods, which is generally healthy. However, the idea that food can meaningfully change your blood's pH is not supported by science, since your body tightly controls its own pH. Most benefits people see likely come from simply eating more whole plant foods.

Dietary pattern emphasizing fruits, vegetables, legumes, and limiting meat, dairy, and processed foods

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

Alkaline Diet: dosing

There is no standard 'dose' for the alkaline diet because it is an eating pattern, not a pill. In general, it means filling more of your plate with fruits, vegetables, and legumes while cutting back on processed foods, added sugar, and excess meat.If you choose to follow it, aim for a balanced version that still includes enough protein, calcium, and other key nutrients. A registered dietitian or your pharmacist can help you adjust the plan safely, especially if you have a health condition or take medications.
