A Canadian study has indicated that, contrary to previous claims that Vioxx was only dangerous with long-term use, those who used the drug were at the highest risk of having a heart attack during the first few weeks.
This may spark further lawsuits against Vioxx manufacturer Merck.
Merck Attacks Credibility
Merck continues to claim that the drug is responsible for no deaths, and denies that they deliberately concealed information about Vioxx's health risks. Merck has already argued that the Canadian study, which was based on patient medical records, has less credibility than Merck's own controlled, clinical studies.
50-50 Record
Merck is already fighting over 11,500 lawsuits from former Vioxx users and their families. So far, it has lost two cases, won two cases, and been given a split verdict in a fifth.
