Ribavirin solution may cause serious birth defects and/or fetal death when used during pregnancy. It should not be used by women who are pregnant or by men whose female partners are pregnant. Women of childbearing potential who either take ribavirin solution or are sexual partners of men who take ribavirin solution must:

  • have a negative pregnancy test immediately before therapy with ribavirin solution is started.
  • avoid becoming pregnant during therapy with ribavirin solution or within the first 6 months after ribavirin solution is stopped.

At least 2 reliable forms of effective birth control must be used during treatment with ribavirin solution and for 6 months after treatment with ribavirin solution is stopped. If you or your sexual partner becomes pregnant while taking ribavirin solution or within 6 months after ribavirin solution is stopped, contact your doctor right away.

Use of ribavirin solution alone is not effective for treating chronic hepatitis C infection. Ribavirin solution must be used with another medicine (interferon) in order to treat hepatitis C infection.

Tell your doctor if you have ever had heart problems. Do not take ribavirin solution if you have a history of serious or uncontrolled heart problems. Call your doctor right away if you have chest pain while taking ribavirin solution.
