What Exviera is and What it is Used For

Exviera is an antiviral medicine used to treat adults with chronic (long-term) hepatitis C (an infectious disease that affects the liver, caused by the hepatitis C virus). It contains the active substance dasabuvir.

Exviera works by stopping the hepatitis C virus from multiplying and infecting new cells, thus clearing the virus from your blood over a period of time.

Exviera tablets do not work on their own. They are always taken with another antiviral medicine containing ombitasvir/paritaprevir/ritonavir. Some patients may also take an antiviral medicine called ribavirin. Your doctor will talk with you about which of these medicines to take with Exviera.

It is very important that you also read the package leaflets for the other antiviral medicines that you take with Exviera. If you have any questions about your medicines, please ask your doctor or pharmacist.

This is because serious or lifethreatening effects can occur when Exviera and ombitasvir/paritaprevir/ritonavir are taken with these medicines.

If any of the above apply to you (or you are not sure), talk to your doctor or pharmacist before taking Exviera.

Blood Tests

Your doctor will test your blood before, during and after your treatment with Exviera. This is so that your doctor can:

  • Decide what other medicines you should take with Exviera and for how long.
  • Confirm if your treatment has worked and if you are free of the hepatitis C virus.
  • Check for side effects of Exviera or other antiviral medicines your doctor has prescribed for you to use with Exviera (such as “ombitasvir/paritaprevir/ritonavir” and “ribavirin”).

Pregnancy and Contraception

The effects of Exviera during pregnancy are not known. Exviera should not be used during pregnancy or in women of childbearing potential not using effective contraception.

  • You or your partner must use an effective method of contraception during treatment. Contraceptive medicines that contains ethinylestradiol cannot be used in combination with Exviera. Ask your doctor about the best contraception for you.

Extra precautions are needed if Exviera is taken together with ribavirin. Ribavirin may cause severe birth defects. Ribavirin stays for a long time in the body after treatment is stopped, and effective contraception is therefore needed both during treatment and for some time afterwards.

  • There is a risk for birth defects when ribavirin is given to a female patient that becomes pregnant.
  • There may also be a risk for birth defects if ribavirin is taken by a male patient, whose female partner becomes pregnant.
  • Read the “Contraception” section of the package leaflet for ribavirin very carefully. It is important that both men and women read the information.
  • If you or your partner becomes pregnant during treatment with Exviera and ribavirin or in the months that follow, you must contact your doctor immediately.

Breastfeeding

You should not breastfeed during treatment with Exviera. It is not known whether the active substance in Exviera (dasabuvir), passes into breast milk.

Driving and Using Machines

Some patients have reported feeling very tired when taking Exviera with other medicines for their hepatitis C infection. If you feel tired, do not drive or use any machines.

Exviera Contains Lactose

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.

How to Take Exviera
