Ganciclovir Pregnancy Warnings

This drug should not be used during pregnancy unless clinical need for treating the mother outweighs the potential risk of teratogenic damage to the fetus

AU TGA pregnancy category: D
US FDA pregnancy category: Not assigned

Comments:
-Pregnancy should be avoided in females patients and female partners of male patients using this drug; patients should be advised of the potential risk to the fetus and the need to use contraceptive measures.
-Females of reproductive potential should undergo pregnancy testing before starting therapy and use effective contraception during therapy and for at least 30 days after the last dose.
-Male patients should be advised to use barrier contraception (condoms) during and for at least 90 days after their last dose.

Based on animal studies, this drug has the potential to cause birth defects in humans. Animal studies have revealed evidence of embryolethality, fetotoxicity, and teratogenicity including fetal resorptions, increased embryofetal mortality, fetal growth retardation, structural abnormalities of multiple fetal organs (including cleft palate, anophthalmia/microphthalmia, hydrocephalus, brachygnathia, aplastic organs [kidneys, pancreas]), hypoplasia of the testes and seminal vesicles in male offspring, and pathologic changes in the nonglandular region of the stomach. Ex vivo data has shown this drug crosses the placenta, most likely by simple diffusion. There are no controlled data in human pregnancy.

Based on ganciclovir animal data, this drug may cause temporary or permanent inhibition of spermatogenesis in males and suppression of fertility in females at recommended human doses.

AU TGA pregnancy category D: Drugs which have caused, are suspected to have caused or may be expected to cause, an increased incidence of human fetal malformations or irreversible damage. These drugs may also have adverse pharmacological effects. Accompanying texts should be consulted for further details.

US FDA pregnancy category Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D, and X are being phased out.
