Rilpivirine brand names: Edurant, Edurant Ped.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Picamilon and Rilpivirine 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. Additionally, although there is no interaction, the label for Rilpivirine states a food rule worth keeping to.

Picamilon and Rilpivirine

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 Rilpivirine 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 Rilpivirine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Rilpivirine is filed under 5 classifications — including non-nucleoside reverse transcriptase inhibitors (nnrtis), qt interval-prolonging drugs, hepatotoxic drugs. Picamilon has documented interactions with 1 drug class — the most serious being niacin (moderate) — and none of Rilpivirine’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 Rilpivirine’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 Rilpivirine’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. 2 of them are worth acting on rather than waiting out — marked below.

  • Liver problems Worth acting on
  • An allergic reaction Worth acting on
  • Trouble sleeping
  • A skin rash
  • Headache

From the ADVERSE REACTIONS section of the FDA label for Rilpivirine. 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.

How to take them

Some Rilpivirine Products Have a Food Rule — Picamilon Should Not Break It

At least one FDA label for a product containing Rilpivirine says to take it with food. If you take Picamilon on an empty stomach out of habit, keep them separate — and take Rilpivirine with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Rilpivirine products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

2 DOSAGE AND ADMINISTRATION One 25 mg rilpivirine tablet taken once daily with a meal for patients weighing at least 35 kg.

From the Dosage and Administration section of the FDA label we read for Rilpivirine — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

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 Rilpivirine

What Is Rilpivirine Used For?

Brand names: Edurant, Edurant Ped

Rilpivirine tablets (sold as Edurant, Edurant Ped, and generic rilpivirine) are used along with other antiretroviral medicines to treat HIV-1 infection in patients who have not previously been treated with HIV medicines (treatment-naïve). Eligibility depends on age, body weight, and the level of virus in the blood at the start of treatment.

Edurant tablets are also approved, in combination with cabotegravir (Vocabria), for short-term oral use in adults and adolescents who are already virologically suppressed — specifically as a lead-in before starting the long-acting injectable regimen Cabenuva, or as a bridge if a Cabenuva injection dose will be missed.

Most-Reported Side Effects for Rilpivirine

From FAERS, the FDA’s public side-effect reporting system (24,864 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Bone density decreased 4,430 reports
Renal injury 3,215 reports
Skeletal injury 2,981 reports

Taking Picamilon and Rilpivirine Together: Common Questions

Is it safe to take Picamilon with Rilpivirine?
We do not list a known interaction between Picamilon and Rilpivirine. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Should I take Picamilon and Rilpivirine at the same time of day?
At least one FDA label for a product containing Rilpivirine says to take it with food. If you take Picamilon on an empty stomach out of habit, keep them separate and take Rilpivirine with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Rilpivirine products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Picamilon and Rilpivirine combination checked?
Interactions in our licensed database are recorded against drug classes. Rilpivirine is filed under 5 classifications, and Picamilon has documented interactions with 1 drug class — none of Rilpivirine's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Picamilon interact with any other medications?
Yes. Picamilon has 3 documented drug interactions in our database — Rilpivirine is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Rilpivirine interact with any supplements?
Yes. Rilpivirine has documented interactions with 175 supplements in our database — Picamilon is not one of them. The Rilpivirine interaction page linked on this page lists every one, ranked by severity.
