Unfortunately, the use of benzocaine throat spray is not recommended for pregnant women. While it can provide temporary relief from a sore throat, benzocaine has been linked to possible adverse effects such as dizziness and skin irritation. Additionally, studies have found that certain ingredients in benzocaine may be absorbed by the mother and passed along to her unborn baby which could lead to potential health risks or complications. If you experience any symptoms related to your sore throat during pregnancy, it would be best to talk with your doctor about safe treatment options before using any over-the-counter medications.
