Bupivacaine is a local anesthetic commonly used to numb specific areas of the body during medical procedures. It works by blocking nerve signals in the targeted area, providing pain relief during surgeries, dental work, and labor. Bupivacaine is often preferred for its long-lasting effects compared to other anesthetics. This medication can be administered through injections or as an epidural, depending on the procedure. While generally safe, bupivacaine can cause side effects such as dizziness, headache, or allergic reactions in some individuals. Proper dosage and administration are crucial to minimize risks and ensure effective pain management.
