This medication can cause birth defects or death in an unborn baby.

• If you are a woman, do not take ribavirin if you are pregnant.

Ribavirin may decrease the number of red blood cells in your body. This is called anemia and it can be life-threatening in people who have heart disease or circulation problems. To be sure this medication is not causing harmful effects, your blood will need to be tested on a regular basis. Do not miss any scheduled visits to your doctor.
