Grapefruit Diet and Avatrombopag Maleate

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

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

Grapefruit 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.

Grapefruit Diet safety at a glance

Grapefruit Diet overall Use caution Grapefruit is a healthy food, but very low-calorie versions of this diet can be hard to sustain and grapefruit affects many medications.
Pregnancy Use caution Eating grapefruit as food is generally fine, but very low-calorie diets should be avoided during pregnancy.
Breastfeeding Use caution Grapefruit as food is usually fine, but restrictive dieting while breastfeeding is not recommended.

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

What Avatrombopag Maleate’s Own FDA Label Lists

This is not an interaction — none of it involves Grapefruit Diet. These are the most notable effects listed in the ADVERSE REACTIONS section of Avatrombopag Maleate’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 Grapefruit Diet and take the medicine. 5 of them are worth acting on rather than waiting out — marked below.

  • Low sodium Worth acting on
  • A low platelet count Worth acting on
  • Anemia Worth acting on
  • Bleeding or bruising Worth acting on
  • A higher chance of infection Worth acting on
  • Sore throat
  • Cough
  • Joint pain

From our pharmacist’s overview on the Avatrombopag Maleate page

“Avatrombopag maleate (Doptelet) exists to raise a low platelet count, so anything that drags its blood level down invites the bleeding risk it was prescribed to prevent. I would handle this list of 54 supplements with real care, and the two rated major come first.”

About Grapefruit Diet

What is Grapefruit Diet?

  • Weight loss
  • Appetite control
  • Short-term dieting
  • Blood sugar support
  • General 'detox' plans

The 'Grapefruit Diet' is a fad eating plan that pairs grapefruit or grapefruit juice with low-calorie meals, claiming the fruit burns fat. Any weight loss is most likely from cutting calories rather than a special fat-burning property of grapefruit. Grapefruit interacts with many medications, so talk to your pharmacist or doctor before starting.

Fruit and fruit juice (Citrus paradisi) · Fresh grapefruit, grapefruit juice, and as part of structured low-calorie meal plans; also grapefruit extract capsules sometimes marketed for weight loss

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

Grapefruit Diet: dosing

There is no standardized or medically established dose for the Grapefruit Diet. Plans typically suggest eating half a grapefruit or drinking a small glass of grapefruit juice with meals, but these amounts vary by version and are not based on solid research.If you choose to add grapefruit to your diet, a reasonable, food-based approach is far safer than a strict, very low-calorie plan.

About Avatrombopag

What Is Avatrombopag Used For?

Brand name: Doptelet

Avatrombopag treats thrombocytopenia (a low platelet count that raises bleeding risk) in three groups of patients. Doptelet tablets are used in adults with chronic liver disease who need their platelet count raised before a medical procedure, and in adults with chronic immune thrombocytopenia (ITP) whose platelet count has not responded well enough to earlier treatments. Doptelet tablets are also used in children aged 6 years and older with persistent or chronic ITP who have not responded to prior treatment.

Doptelet Sprinkle (oral granules) is specifically indicated for children aged 1 year to less than 6 years with persistent or chronic ITP who have not responded adequately to a previous treatment.
