Antiviral drug
Direct-acting antivirals

The term Direct-acting antivirals (DAA) has long been associated with the combination of antiviral drugs used to treat hepatitis C infections. These are the more effective than older treatments such as ribavirin (partially indirectly acting) and interferon (indirect acting). The DAA drugs against hepatitis C are taken orally, as tablets, for 8 to 12 weeks. The treatment depends on the type or types (genotypes) of hepatitis C virus that are causing the infection. Both during and at the end of treatment, blood tests are used to monitor the effectiveness of the treatment and subsequent cure.
