Name a contraindication for the use of ribavirin.

Ribavirin is an antiviral medication commonly used to treat hepatitis C and certain viral infections. One significant contraindication for the use of ribavirin is pregnancy due to its potential teratogenic effects. Ribavirin has been shown to cause severe birth defects and fetal death when administered to pregnant women. Therefore, women of childbearing age are advised to avoid ribavirin unless they are using effective contraception and are not pregnant.

The emphasis on avoiding ribavirin during pregnancy is crucial to prevent potential harm to the developing fetus. This underscores the importance of a thorough medical history and counseling for women who may become pregnant while undergoing treatment with this drug. Addressing conditions like hypertension, pneumonia, or diabetes might require careful monitoring and management but do not pose the same level of risk as the teratogenic effects associated with ribavirin in pregnancy.
