In 2002, following Cheryl Unterreiner’s aortic valve replacement, Dr. David Pernikoff prescribed her an anticoagulant called Warfarin. Warfarin is a type of medication that is used to prevent blood clots from forming or growing larger in your blood and blood vessels. Warfarin is customarily prescribed for people with replacement or mechanical heart valves, or individuals with certain types of irregular heartbeat. This type of medication is measured by international normalized ratio, otherwise known as INR. Doctors must keep track of INR to ensure an adequate, yet safe, dose is taken.
In Cheryl’s case, six years after starting Warfarin, her INR levels began to fall below normal. After noticing her levels were dropping, she contacted Dr. Pernikoff in April of 2008. According to her complaint, Cheryl states that Dr. Pernikoff simply increased her Warfarin dosage, without monitoring her INR levels and without seeing Cheryl in his office.
In October of 2008, Cheryl suffered a stroke at her home. After being transferred to the hospital, her condition got worse. Cheryl suffered an intracranial hemorrhage, which led to brain stem herniation.
According to her lawsuit, Cheryl has experienced a great deal of injury. She is no longer capable of speaking clearly, and the herniation in her brain has also affected parts of her body, causing emotional control issues, memory loss, and decreased motor skills.
