If you can become pregnant, it’s important to consider whether Tamiflu is a safe choice for you.

It’s not known for sure whether it’s safe to take Tamiflu when pregnant. Experts haven’t performed any clinical trials comparing the use of Tamiflu versus a placebo (treatment with no active drug) in pregnant people yet.

However, some studies involved pregnant females who took Tamiflu during any trimester of their pregnancy. These studies didn’t show an increased risk of congenital anomalies (commonly called birth defects) when the participants took Tamiflu.

In animal studies, Tamiflu also didn’t cause any negative effects in fetuses exposed to the drug. But keep in mind that animal studies don’t always predict what will happen in humans.

The Centers for Disease Control and Prevention (CDC)Trusted Source recommends Tamiflu as the preferred option for treating flu during pregnancy.
