You may already be infected with hepatitis B (a virus that infects the liver and may cause severe liver damage) but not have any symptoms of the disease. In this case, taking daclatasvir may increase the risk that your infection will become more serious or life-threatening and you will develop symptoms. Tell your doctor if you have or ever had a hepatitis B virus infection. Your doctor will order a blood test to see if you have or have ever had hepatitis B infection. Your doctor will also monitor you for signs of hepatitis B infection during and for several months after your treatment. If necessary, your doctor may give you medication to treat this infection before and during your treatment with daclatasvir. If you experience any of the following symptoms during or after your treatment, call your doctor immediately: excessive tiredness, yellowing of the skin or eyes, loss of appetite, nausea or vomiting, pale stools, stomach pain, or dark urine.

Keep all appointments with your doctor and the laboratory. Your doctor may order certain tests before, during, and after your treatment to check your body’s response to daclatasvir.

Talk to your doctor about the risk(s) of taking daclatasvir.

🔔 Why is this medication prescribed?

Daclatasvir is used along with another medication (sofosbuvir [Solvadi]) to treat a certain type of chronic hepatitis C (an ongoing viral infection that damages the liver). Daclatasvir is in a class of antiviral medications called hepatitis C virus (HCV) NS5A inhibitors. It works by stopping the virus that causes hepatitis C from spreading inside the body. It is not known if daclatasvir prevents the spread of hepatitis C to other people.

🔔 How should this medicine be used?

Daclatasvir comes as a tablet to take by mouth. It is usually taken with or without food once a day. Daclatasvir must be taken in combination with sofosbuvir, usually for 12 weeks. Take daclatasvir at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take daclatasvir exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Interestingly, Americans show more favor toward Medicare for All healthcare initiatives than they do toward these efforts when they are labeled as “single payer,” most likely due to the popularity of the Medicare program, STAT

Continue to take daclatasvir even if you feel well. Do not stop taking daclatasvir or sofosbuvir without talking to your doctor.

Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.
