Trovan is a drug severely restricted in use because of its potential to cause liver damage. Injury to the liver as a result of taking Trovan can lead to liver failure and death.

In 2011, Pfizer paid $700,000 to four families who lost children during the Trovan trials.

In addition, the company set up a $35 million fund for those affected by Trovan. Pfizer also agreed to sponsor health projects in Kano, Nigeria.
