Olaparib brand name: Lynparza.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Mediterranean Diet and Olaparib 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.

Mediterranean Diet and Olaparib

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

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

Mediterranean 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.

What Olaparib’s Own FDA Label Lists

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

  • Blood clots Worth acting on
  • Anemia Worth acting on mentioned in 7.8% of FDA reports for Olaparib
  • A low platelet count Worth acting on
  • Raised blood pressure Worth acting on
  • Shortness of breath Worth acting on
  • A low white blood cell count Worth acting on
  • Liver problems Worth acting on
  • A higher chance of infection Worth acting on
  • A change in taste
  • Mouth irritation or sores

Showing the 10 most notable of 23 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 Olaparib. Read the label on DailyMed › Where a percentage is shown, it is the share of 20,798 voluntary FDA FAERS reports for Olaparib that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Mediterranean Diet’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Mediterranean Diet side to compare — that is a limit of the record, not a statement that Mediterranean Diet has no side effects.

Overlapping uses

What Olaparib Is Prescribed For, and What Mediterranean Diet Has Been Studied For

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

Olaparib is prescribed for: Lynparza (olaparib) is used to treat adults with certain ovarian, fallopian tube, or primary peritoneal cancers that carry BRCA or other DNA-repair gene mutations — both as a maintenance therapy after platinum-based chemotherapy (including in combination with bevacizumab for some patients) and for recurrent disease. It is also approved for HER2-negative breast cancer with a germline BRCA mutation, both in early high-risk disease (adjuvant setting) and in metastatic disease. Lynparza is additionally used as maintenance therapy for adults with germline BRCA-mutated metastatic pancreatic adenocarcinoma whose disease has not progressed on first-line platinum-based chemotherapy, and for adults with certain gene-mutated metastatic castration-resistant prostate cancer — either alone (after prior enzalutamide or abiraterone) or in combination with abiraterone and prednisone or prednisolone. All uses require testing for specific genetic mutations using an FDA-approved companion diagnostic before starting treatment.

Mediterranean Diet has been studied for:

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

    Mediterranean Diet for prostate cancer

    The Mediterranean diet may be associated with reductions in the risk of overall mortality, but not prostate cancer-related mortality, in patients with prostate cancer.

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

    Mediterranean Diet for breast cancer

    The Mediterranean diet may be associated with reductions in the risk of mortality in patients with breast 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 Olaparib on your own; if you are taking Mediterranean Diet for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Olaparib

This page covers Mediterranean Diet only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Olaparib page lists 138 supplements it has a documented interaction with, worst first, each one explained.

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 · 94 moderate · 41 minor.

From our pharmacist’s overview on the Olaparib page

“Grapefruit is the first thing to drop if you take Olaparib (Lynparza). It blocks CYP3A4, the liver enzyme that clears this cancer drug, so levels can climb and side effects with them.”

Eating pattern

About Mediterranean Diet

What is Mediterranean Diet?

  • Heart health
  • Weight management
  • Type 2 diabetes prevention
  • Brain and memory health
  • Reducing inflammation
  • General longevity

The Mediterranean diet is an eating pattern rich in vegetables, fruits, whole grains, legumes, nuts, fish, and olive oil, with limited red meat and processed foods. It has some of the strongest evidence of any diet for supporting heart health and is widely considered safe for most people. Talk to your doctor or a dietitian before making big changes, especially if you have a medical condition.

Whole-food eating pattern (not a pill or supplement)

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

Mediterranean Diet: dosing

There is no pill or fixed "dose" for the Mediterranean diet—it is an overall pattern. The general approach is to make vegetables, fruits, whole grains, beans, and olive oil the base of most meals, eat fish a couple of times per week, choose nuts and seeds for snacks, and limit red meat, processed foods, and sweets.A registered dietitian can help you tailor the pattern to your calorie needs, health conditions, and food preferences.

Following Mediterranean Diet While Taking Olaparib: Common Questions

Is it safe to follow Mediterranean Diet while taking Olaparib?

Are Mediterranean Diet and Olaparib used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Mediterranean Diet in each. That is a conversation for your prescriber, especially if Olaparib is being adjusted to a target.
Does Olaparib interact with any supplements?
Yes. Olaparib has documented interactions with 138 supplements in our database — Mediterranean Diet is not one of them. The Olaparib interaction page linked on this page lists every one, ranked by severity.
