As of now, no study has been done to show whether Botox can cause harm to the fetus.

Therefore, it is recommended to go to the hospital in time to do an exclusion test to observe whether the fetus is affected by Botox, combine the test results and listen to the professional doctor’s advice before determining the next step of the treatment plan.
