The bottom line No known interaction

We found no known interaction between Picamilon and Panitumumab 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.

Picamilon and Panitumumab

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 Panitumumab and Picamilon 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.

Picamilon safety at a glance

Picamilon overall Use caution Human safety data are limited and its legal status as a supplement is questionable in some countries.
Pregnancy Avoid No reliable safety data exist, so it should be avoided during pregnancy.
Breastfeeding Avoid No safety information is available, so avoid 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 Panitumumab

Interactions in our licensed database are recorded against drug classes, not just single drug names. Panitumumab is filed under a single classification — antineoplastics. Picamilon has documented interactions with 1 drug class — the most serious being niacin (moderate) — and none of Panitumumab’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 Panitumumab’s Own FDA Label Lists

This is not an interaction — none of it involves Picamilon. These are the most notable effects listed in the ADVERSE REACTIONS section of Panitumumab’s own FDA label, for the medication by itself.

  • An electrolyte imbalance Worth acting on
  • Low magnesium Worth acting on
  • A bowel blockage Worth acting on
  • Dehydration Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Panitumumab. Read the label on DailyMed › Picamilon’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Picamilon side to compare — that is a limit of the record, not a statement that Picamilon has no side effects.

Everything else you take

See Every Supplement That Interacts With Panitumumab

This page covers Picamilon only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Panitumumab page lists 1 supplement it has a documented interaction with, worst first, each one explained.

The most serious there right now: American Pawpaw (minor).

By severity: 1 minor.

From our pharmacist’s overview on the Panitumumab page

“Panitumumab (Vectibix) is an infused antibody used against certain colorectal cancers, and its supplement interaction file is about as short as they come. A single ingredient appears on it, American pawpaw, and even that is rated minor, with the evidence suggesting the interaction is unlikely to occur at all.”

About Picamilon

What is Picamilon?

  • Anxiety and stress
  • Mental focus and cognition
  • Low mood
  • Migraine or headache
  • Fatigue and energy

Picamilon is a synthetic compound made by joining niacin (vitamin B3) and GABA, originally developed in the former Soviet Union as a prescription drug. It is sold in some countries as a supplement for anxiety, focus, and mood, but high-quality human evidence is very limited, and U.S. regulators have stated it does not qualify as a legal dietary supplement ingredient. Talk to a pharmacist or doctor before using it.

Synthetic compound (not from a plant) · Capsules, tablets, powder

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

Picamilon: dosing

There is no officially established or standardized dose of picamilon for supplement use, and quality control of products is uncertain.If a product is available to you, follow the directions on the label and do not exceed them.

About Panitumumab Injection

What Is Panitumumab Injection Used For?

Brand name: Vectibix

Vectibix (panitumumab injection) is used to treat metastatic colorectal cancer (mCRC) in adults. It is approved for patients whose tumors have a specific genetic profile — either wild-type RAS (no RAS mutations in KRAS or NRAS) or a KRAS G12C mutation — as confirmed by an FDA-approved test before starting treatment.

For wild-type RAS mCRC, Vectibix may be used alone after prior chemotherapy has stopped working, or in combination with FOLFOX chemotherapy as a first-line treatment. For KRAS G12C-mutated mCRC, Vectibix is used in combination with sotorasib in patients who have already received fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy. Vectibix is not appropriate for patients with RAS-mutant mCRC (except in the specific KRAS G12C combination setting) or for patients whose RAS mutation status is unknown.
