Tyzeka and Pregnancy
In many cases, the benefits of using Tyzeka (telbivudine) during pregnancy clearly outweigh the risks. In addition, this drug did not appear to cause birth defects or other problems when high doses were given to pregnant rats and rabbits in animal studies. Therefore, the FDA has classified it as a pregnancy Category B drug, meaning it is generally considered safe for use in pregnant women.
Can Pregnant Women Take Tyzeka?Tyzeka® (telbivudine) is a prescription medication used for the treatment of chronic (long-term) hepatitis B virus infections. The medication is generally considered safe for use during pregnancy, based on animal studies looking at the effects of Tyzeka during pregnancy.
What Is Pregnancy Category B?The U.S. Food and Drug Administration (FDA) uses a category system to classify the possible risks to a fetus when a specific medicine is taken during pregnancy. Tyzeka is classified as a pregnancy Category B medication.
Pregnancy Category B is given to medicines that have not been adequately studied in pregnant humans but do not appear to cause harm to the fetus in animal studies. Medications that have been shown to be safe for use in pregnant women, but have caused problems in laboratory animals, are also given a Category B rating.
Tyzeka has not been adequately studied in pregnant women. However, the drug did not appear to cause birth defects or other problems when given in high doses to pregnant rats and rabbits.
However, it is important to note that animals do not always respond to medicines in the same way that humans do. Therefore, a pregnancy Category B medicine should be given to a pregnant woman only if the healthcare provider believes that the benefits to the woman outweigh any possible risks to her unborn child.
