In June 2010, health insurance network Blue Cross Blue Shield (BCBS) filed a lawsuit against Pfizer for allegedly illegally marketing drugs Bextra, Geodon and Lyrica. BCBS alleged that Pfizer used kickbacks and wrongly persuaded doctors to prescribe the drugs. According to the lawsuit, Pfizer handed out 'misleading' materials on

2011 Nigeria Trovafloxacin lawsuit settlement

In 1996, an outbreak of measles, cholera, and bacterial meningitis occurred in Nigeria. Pfizer representatives and personnel from a contract research organization (CRO) traveled to Kano to set up a clinical trial and administer an experimental

, to approximately 200 children. Tests in animals showed that Trovan had life-threatening side effects, including joint disease, abnormal cartilage growth, liver damage, and a degenerative bone condition. Pfizer’s representatives did not alert the parents or patients about the serious risks involved, or tell them about an effective conventional treatment that Doctors without Borders was providing at the same site. Local Kano officials reported that more than fifty children died in the experiment, while many others developed mental and physical deformities such as blindness, deafness, paralysis, and brain damage. The nature and frequency of both fatalities and other adverse outcomes were similar to those historically found among pediatric patients treated for meningitis in sub-Saharan Africa. In 2001, families of the children, as well as the governments of Kano and Nigeria, filed lawsuits regarding the treatment. According to ''

'', " searchers did not obtain signed consent forms, and medical personnel said Pfizer did not tell parents their children were getting the experimental drug." The lawsuits also accused Pfizer of using the outbreak to perform unapproved human testing, as well as allegedly under-dosing a control group being treated with traditional antibiotics in order to skew the results of the trial in favor of Trovan. Nigerian medical personnel as well as at least one Pfizer physician said the trial was conducted without regulatory approval. In 2007, Pfizer published a Statement of Defense letter, stating that the drug's oral form was safer and easier to administer. Trovan had been used safely in more than five thousand Americans prior to the Nigerian trial, and mortality in the patients treated by Pfizer was lower than that observed historically in African meningitis epidemics. No unusual side effects, unrelated to meningitis, were observed after four weeks. In June 2010, the US Supreme Court rejected Pfizer's appeal against a ruling allowing lawsuits by the Nigerian families to proceed. In December 2010, the

In response, the company released a press statement describing the allegations as "preposterous" and saying that it acted in good faith. Aondoakka, who had allegedly demanded bribes from Pfizer in return for a settlement of the case, was declared unfit for office and had his U.S. visa revoked in association with corruption charges in 2010. The lawsuits were eventually settled out of court. Pfizer committed to paying "to compensate the families of children in the study", another $30 million to "support healthcare initiatives in Kano", and $10 million to cover legal costs. Payouts began in 2011.


2022 Inflating Prices fine

In July 2022, UK antitrust authorities fined Pfizer £63 million for unfairly high priced drug that aids in controlling epileptic seizures. The Competition and Markets Authority stated that the company took advantage of loopholes by de-branding epilepsy drug Epanutin, by doing so the price of Epanutin's price was not regulated to the same standards the company are used to and therefore the price of the drug was raised. It was stated that over a four-year period, Pfizer had billed Epanutin for around 780% and 1,600% higher than its standard price.
