Durasil drops: Brazil banned the supplement with unknown origin

On 2 February 2026, Brazil’s Anvisa said it had seized and banned the “Durasil brand food supplement in drops” across all lots. Resolution RE 406 identifies the company and tax ID as unknown. The regulator described ads on Root Brasil and online marketplaces promising pain relief, stronger erections and improved erectile function. Anvisa said those therapeutic and functional claims were irregular for foods. [1][2][3]

What was banned

The prohibition covers manufacture, sale, distribution, advertising and use of the identified product. This is not a ruling about every men’s health product: it concerns drops sold as a supplement whose origin and manufacturer were unknown to the authorities. Anvisa also ordered the product seized. [1][2][3]

The alert does not cover every product called Durasil

The resolution does not publish a formula or dose and does not report a laboratory test finding a hidden medicine. It also does not establish that serums, capsules or other products named Durasil, with a different form or seller, are the same item. The sources do not verify a current price or a costly course pushed by phone. This review is limited to the drops Anvisa identified in Brazil. [1][2][3]

Why these promises are not treatment

A food supplement is not a medicine and must not be presented as treatment for a disease or dysfunction. Anvisa says supplements complement the diet; they do not treat, prevent or cure disease. Recurrent erection difficulties deserve assessment because causes vary, and primary care can begin that evaluation. An unidentified product is no substitute for that consultation. [4][5]

What to do

• Do not buy or use the Durasil drops covered by Resolution RE 406/2026. [1][2][3]
• If you have used them, keep the bottle and note the lot, seller and date. Speak with a health professional if you have symptoms or concerns.
• If erection problems keep happening, seek care instead of relying on drops with no known origin; do not stop prescribed medicines on your own. [5]
• If you see the offer for sale in Brazil, save the listing and report it to Anvisa or local health surveillance. [1]

Our verdict

We do not recommend the Durasil drops identified and banned by Anvisa. The manufacturer and origin were unknown, and the product was advertised with claims to relieve pain and improve erections—claims the agency considered irregular for a supplement. That is a concrete reason not to buy it. This resolution does not support claims that the drops contained hidden drugs, that every product with the same name is identical, or that buyers faced phone pressure.
