The organiser of the anti-Rigvir skeptic community and author of this blog, Austra Muizniece aka @zimbabve on TW, interviewed by European Skeptics Podcast:

“This week we welcome back Latvian activist Austra Muizniece, fearless fighter against the fake ‘cancer treatment’ Rigvir. Shamelessly and corruptly approved in Latvia just two days before Latvia joined the EU, Rigvir has been claimed to be a cure at first for melanoma, and later for virtually any kind of cancer. Austra, herself a cancer survivor, has together with fellow skeptics lobbied for years to get Rigvir off the market as there has never been any evidence presented to support its efficacy. Litigation and harassment have been their reward, but finally now it seems like this fraudulent substance is being withdrawn from the market after 15 years of providing nothing but false hope to cancer patients.”

March / April

Calls for official probe over Rigvir cancer treatment scandal: in what could be the most serious blow for Rigvir yet, there is risk of criminal liability for possibly having misled the patients, who are now in the worrisome situation of possibly having been treated with sub-par medicines. “The question is, then, as to why it took so long for the medicines watchdog to test Rigvir samples?” –

Institution asks Rigvir to repay state funds used for botched drug batch. Also, in line with the regulations on distribution of medicine, the owner of the registered medicine has the duty to compensate for loss to drug wholesalers, pharmacies and other persons who received the medicines outside the compensation system:

Medical rights expert and lawyer Solvita Olsena invited patients to turn to the police, asking to check whether their Rigvir is what it says it is on the label. In an April 3 post on that appears on, neurosurgeon Renārs Putniņš joined the growing ranks of doctors to condemn Rigvir, calling the entire Rigvir ordeal an affair and asked for an investigation as to how the medicine could have been registered in the first place. “There should be someone on the seat of the accused, at the very least, so that we don’t have to experience similar situations in the future!” he wrote.

“It’s like buying what you think is lemon juice, but finding that what you have is lemon-flavored water:”

The Health Inspectorate and the State Agency of Medicines (ZVA) decided last autumn to test the anti-cancer product Rigvir in the laboratory and the preliminary results have proven to be deeply concerning, reported De Facto March 24. A sample of Rigvir was sent to an independent laboratory in the United Kingdom. It found that the amount of Rigvir ECHO-7 virus, which is supposed to fight cancer cells, is of a much smaller amount than promised by the manufacturer:

Minister of Health Anda Čakša is quoted saying: “A letter by some social group saying they don’t like something – it’s just not helpful. Show us data that this medicine does not work for your patients. We don’t have anything to react to at the moment.

Latvian Inspectorate of Health publishes a decision to apply a fine to SIA Latima, the manufacturer of Rigvir. Inspection concludes that Rigvir advertisements constitute unfair commercial practice, they violate advertising laws of prescription medicine to the general public, and the content of advertisements does not match the registered product specification.

SIA Latima claims that they will appeal the fine.


A local skeptic and a cancer survivor (TW handle: @zimbabve) submits a complaint to the Health Inspectorate of Latvia regarding Rigvir and makes it publicly available, and Latvian media picks up the story (automated translation). Complaint contains examples of illegal, misleading and prolonged advertising of Rigvir directly to general public and cancer patients in magazines, newspapers, in a cancer patient support group, as well as advertising it off-label for multiple forms of cancer. Representatives of Rigvir claim that the official complaint is a part of a “black PR” campaign – a common excuse in Latvian political and business environment.
