Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Allergic reaction: In rare cases, this medication may cause a severe allergic reaction. If you notice hives, swelling of the face or throat, or difficulty breathing, stop the child from inhaling the medication and get immediate medical attention.
Pregnancy: Ribavirin may be harmful to an unborn baby. Women who are pregnant or may become pregnant should not be exposed to ribavirin. To protect an unborn baby, women who are pregnant should not provide care to patients requiring ribavirin.
Breast-feeding: It is not known if ribavirin passes into breast milk. If you are a breast-feeding mother and are exposed to this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
