GENERIC NAME(S): Daclatasvir
OTHER NAME(S): Daklinza Tablet
Although this medication helps many people with hepatitis C, it may cause people who also have another liver problem called hepatitis B to get worse. Before starting this medication, tell your doctor if you have ever had hepatitis B. Tell your doctor right away if you have new or worsening symptoms of liver disease, such as nausea/vomiting that doesn't stop, loss of appetite, stomach/abdominal pain, dark urine or yellowing eyes/skin.Show More
Daclatasvir is used with another antiviral medication (sofosbuvir) to treat chronic (long-lasting) hepatitis C, a viral infection of the liver. Daclatasvir should never be used without sofosbuvir. Daclatasvir and sofosbuvir may also be used with another antiviral medication (ribavirin). These medications together reduce the amount of hepatitis C virus in your body, which helps your immune system fight the infection and may help your liver recover. Chronic hepatitis C infection can cause serious liver problems such as scarring (cirrhosis), or liver cancer.
It is not known if this treatment can prevent you from passing the virus to others. Do not share needles, and practice "safer sex" (including the use of latex condoms) to lower the risk of passing the virus to others.
How to use Daklinza
Read the Patient Information Leaflet if available from your pharmacist before you start taking daclatasvir and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Also read the drug information for your other antiviral medication(s).
Take this medication by mouth with or without food as directed by your doctor, usually once daily.
The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).
This medication works best when the amount of drug in your body is kept at a constant level. Take this drug at evenly spaced intervals. To help you remember, take it at the same time each day.
Continue to take daclatasvir and your other antiviral medication(s) for the full length of time prescribed, even if your symptoms disappear after a short time. Stopping any of the drugs too early may result in a return of the infection.
