Approved for medical use in 2014-2015, Daclatasvir is a medication given orally to treat hepatitis C (aka HCV) by preventing this virus from multiplying in the patient’s body. According to drugs.com, it is also used “in combination with other medications to treat chronic hepatitis C in adults”. Bear in mind that Daclatasvir should not be used alone, but rather in combination with other antiviral medications. It is also worth noting that your doctor will constantly have to check your liver function because Daclatasvir can cause hepatitis B to come back or get worse (that is, if you’ve ever been treated for this condition). Based on the information posted on drugs.com, Daclatasvir can also cause anemia and new liver symptoms – Both of which must be reported to the doctor when they occur. As for the common side effects, they include nausea, headache, and fatigue. Considering the fact that Daclatasvir is sometimes used with Ribavirin, pregnant women must steer clear of Ribavirin as it can cause birth defects or death in an unborn baby. And if you’re not pregnant, avoiding pregnancy during your treatment is highly recommended. Don’t forget to consult your doctor before using Daclatasvir in case you’re nursing a baby.
