If you are beginning treatment for hepatitis C, you may have wondered about direct-acting antivirals. These medications, also known as DAAs, are revolutionizing the way hepatitis C is treated. At HepCMyWay, we understand that being informed about your treatment options is an important part of the decision-making process. That's why we've taken the liberty of explaining how DAAs work and how they are used in the treatment of hepatitis C.
What Are Direct-Acting Antivirals?
The hepatitis C virus is difficult to treat because it can quickly mutate and become resistant to many medications. Direct-acting antivirals are medications designed to specifically target viral proteins and prevent the hepatitis C virus from replicating. These are different from traditional antivirals, which work by suppressing the entire immune system.
Direct-acting antivirals directly target the virus instead of relying on the body's immune system to fight it off, so they can often prove more effective. They are usually taken in combination with other medications, like interferon and ribavirin, which help reduce the risk of relapse.
DAA medications have been developed to be more specific and effective in targeting hepatitis C, as they directly target specific enzymes in the hepatitis C virus. These drugs may be used either as fully oral treatments or in combination with interferon-based regimens. However, the most effective treatments include DAAs as part of combination therapy.
Direct-acting antivirals work by blocking different steps in the replication process of the hepatitis C virus, which makes it difficult for the virus to replicate and spread. This prevents further damage to your liver. Depending on your specific strain of hepatitis C, you may be prescribed one or more direct-acting antivirals.
There are a variety of direct-acting antivirals available, including simeprevir (Olysio), sofosbuvir (Sovaldi), ledipasvir/sofosbuvir (Harvoni), daclatasvir (Daklinza), and velpatasvir/sofosbuvir (Epclusa). Your doctor at HepCMyWay can help you decide which medications are right for your hepatitis C treatment plan.
DAA medications have been developed to be more specific and effective in targeting hepatitis C than previous treatment regimens, as they directly target specific enzymes in the hepatitis C virus.

How Do Direct-Acting Antivirals Work To Treat Hep C?
Direct-acting antivirals work by targeting proteins that are essential for the hepatitis C virus to replicate. By blocking these proteins, DAAs can prevent or slow down the multiplication of HCV and reduce its presence in the body. These medications interfere with viral replication in several different ways: they can block specific enzymes, inhibit viral proteins from binding to cells, or even prevent the virus from entering cells. By targeting these proteins, DAAs are able to stop the virus from replicating and clear it from a person’s system.
In combination with other medications, such as interferon and ribavirin, DAAs can be used to treat all six genotypes of the hepatitis C virus, including the notoriously difficult-to-treat genotype 3. Because DAAs work specifically to target viral proteins, they are often associated with fewer side effects than other treatments. However, it is important to note that common side effects can include headaches, nausea, fatigue, and insomnia.
Direct-acting antivirals have been found to be extremely effective in treating hepatitis C. In clinical studies, DAAs have been shown to produce cure rates that reach up to 95%. When used with other therapies, DAAs may even be able to reduce the amount of time it takes to clear the virus from the body.
What Are The Benefits of DAA Drugs?
Direct-acting antivirals have helped many of our patients get back to a hep C-free life. Patients experience a variety of benefits from these medications such as:
- Since direct-acting antivirals work directly on the hepatitis C virus, they can be used in combination with other medications to provide better results than traditional treatments.
- DAAs are associated with fewer side effects and have been found to produce high cure rates.
- DAAs may be used as a stand-alone treatment or combined with interferon-based regimens.
- Their versatility makes them a powerful tool for treating hepatitis C and provides more options to those diagnosed with the virus.
- DAAs can significantly reduce the amount of time it takes to clear the virus from a person’s system.
