The U.S. Food and Drug Administration last week issued warnings for the new hepatitis medications, Technivie and Viekira Pak, after noticing an alarming trend of liver side effect reports. Patients taking either drug are cautioned to look for symptoms.
Both drugs are sold by Chicago-based pharmaceutical company Abbvie. Viekira Pak was approved by the FDA in December 2014 and Technivie was approved in July 2015, both for the treatment of hepatitis C.
In the short time since, the FDA says it has received over 26 reports of serious liver injury around the world through its Adverse Event Reporting System (AERS). However, since this system relies on voluntary patient and physician reports, the agency estimates the actual rate is higher.
Hepatitis C is a common infection of the liver that causes inflammation. It does not have a cure, but can be controlled with proper treatment. Without treatment, it can advance to more serious liver conditions including cancer and death.
Possible Side Effects include Liver Failure
In a review of submitted adverse event reports, the FDA discovered serious cases of hepatic decompensation and liver failure that in some instances resulted in a liver transplant or death. The conditions surfaced quickly in most patients, usually in the first month of treatment.
However, all of the cases involved patients that were already suffering from advanced liver cirrhosis. Both Technivie and Viekira Pak are not recommended for such patients, which will be more strongly designated with the new warning.
The FDA’s new warning requires that Abbvie amend the drugs’ labels to include information about reports of serious liver injury side effects.
Patients and Doctors Advised to Monitor for Symptoms
According to the FDA, patients taking Viekira Pak or Technivie should not stop taking the drugs without speaking to their doctor first, as doing so might reduce the effectiveness of other hepatitis treatments.
However, doctors and patients should closely monitor for symptoms of worsening liver disease, which may include:
