AbbVie Inc et al, is representative of a group of plaintiffs taking legal action against the marketers of testosterone replacement therapy products for men, according to court documents. Each of these cases shares common questions of fact with over 1750 testosterone actions currently pending in the Illinois District Court, according to court documents. Sharing common questions of fact means the lawsuits make the same allegations against a common group of defendants; in this case, plaintiffs allege the makers of testosterone replacement products glossed over the risks associated with the supplement and exaggerated the benefits, according to court documents. Furthermore, plaintiffs allege marketers engaged in aggressive, off-label marketing campaigns, encouraging men to self-diagnose a fictional disease called "Low-T", according to the initial complaint court document.
