Picamilon + Allopurinol
Allopurinol brand names: Zyloprim, Caplenal, Cosuric, Rimapurinol, Zyloric.
We found no known interaction between Picamilon and Allopurinol 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 Allopurinol
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 Allopurinol 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
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Allopurinol
Interactions in our licensed database are recorded against drug classes, not just single drug names. Allopurinol is filed under 5 classifications — including antigout drugs, nephrotoxic drugs, hepatotoxic drugs. Picamilon has documented interactions with 1 drug class — the most serious being niacin (moderate) — and none of Allopurinol’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.
Picamilon Does Interact With Other Medications

From our pharmacist’s overview on the Allopurinol page
“Allopurinol (Zyloprim) prevents gout attacks by lowering uric acid, and I would give this list real weight, because 5 of the 60 supplements and herbs on file carry a major rating. The largest cluster, 38 ingredients, is products that can stress the liver on their own, and regular beer or wine sits in that major group, since alcohol on…”

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 Allopurinol
What Is Allopurinol Used For?
Brand names: Zyloprim, Caplenal, Cosuric, Rimapurinol, Zyloric
Allopurinol tablets (including Zyloprim) are used in adults to treat the signs and symptoms of gout — including gout attacks, tophi (uric acid deposits), joint damage, and kidney problems caused by uric acid. Allopurinol tablets are also used in adults to reduce recurrent calcium oxalate kidney stones when uric acid in the urine is too high, even after lifestyle changes.
For adults and children with leukemia, lymphoma, or solid tumor cancers, allopurinol is used to control uric acid levels that rise during cancer treatment. The injectable forms — Allopurinol sodium for injection and Aloprim — are specifically for patients who cannot take medicine by mouth and are given intravenously (through a vein) in a hospital or clinical setting. Note: allopurinol tablets are not recommended for people who have high uric acid levels but no symptoms.
Most-Reported Side Effects for Allopurinol
From FAERS, the FDA’s public side-effect reporting system (0 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
