Camu Camu and Afatinib Dimaleate

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 Afatinib Dimaleate and Camu Camu 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Camu Camu at all — not against Afatinib Dimaleate, 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.

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.

Camu Camu safety at a glance

Camu Camu overall Use caution Likely safe as a food, but high-dose supplements lack strong long-term safety data.
Pregnancy Avoid Not enough safety information, so it is best avoided in supplement form during pregnancy.
Breastfeeding Avoid Safety has not been studied, so it is best avoided in supplement form while breastfeeding.

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

What Afatinib Dimaleate’s Own FDA Label Lists

This is not an interaction — none of it involves Camu Camu. These are the most notable effects listed in the ADVERSE REACTIONS section of Afatinib Dimaleate’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. 10 of them are worth acting on rather than waiting out — marked below.

  • Dehydration Worth acting on
  • Low potassium Worth acting on
  • Pancreatitis Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • A severe skin reaction Worth acting on
  • Kidney problems Worth acting on
  • Shortness of breath Worth acting on
  • Liver problems Worth acting on
  • Bleeding or bruising Worth acting on
  • A higher chance of infection Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Afatinib Dimaleate. Read the label on DailyMed › Where a percentage is shown, it is the share of 6,587 voluntary FDA FAERS reports for Afatinib Dimaleate that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Camu Camu’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Camu Camu side to compare — that is a limit of the record, not a statement that Camu Camu has no side effects.

From our pharmacist’s overview on the Afatinib Dimaleate page

“Afatinib (Gilotrif) is a targeted lung cancer therapy, and because its effectiveness depends on keeping a steady blood level, this list deserves genuine care. Most of the 54 supplements here either change how much of the drug the gut absorbs or interfere with P-glycoprotein, a pump that moves afatinib across cell walls, pushing its lev…”

About Camu Camu

What is Camu Camu?

  • Antioxidant support
  • Immune support
  • Vitamin C source
  • General wellness
  • Anti-inflammatory support

Camu camu is an Amazonian berry that is very high in vitamin C and plant antioxidants, which is why it is popular as an immune and antioxidant supplement. Human research is still limited, so most claims are not well proven. It is generally considered safe as a food or supplement for most people, but check with your pharmacist or doctor before starting it.

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

Camu Camu: dosing

There is no official or standardized dose for camu camu. Products vary widely in strength and vitamin C content, so the right amount depends on the specific product.The safest approach is to follow the directions on the product label and not exceed them.

About Afatinib

What Is Afatinib Used For?
