The European Medicines Agency warned on Friday that some of the most successful hepatitis C treatments on the market could reactivate hepatitis B in patients, the second time this year it has raised safety concerns over these treatments.
The latest health warning covers some of the top-selling products in the multi-billion dollar hepatitis C market, including Sovaldi, Exviera, Viekirax, Olysio and Daklinza.
These drugs cure well over 90 percent of patients with the liver disease and also cuts down the duration of the treatment.
