Naropin 0.75% Injection is a local anesthetic. It is used during minor surgical procedures such as dental, oral, diagnostic, or other therapeutic procedures to anesthetize or numb the surgical area. Naropin 0.75% Injection must be administered by healthcare professionals. It blocks the pain signals to reach the brain by temporarily numbing the surgical area and helps to perform a painless procedure. The most common side effects of this medicine include hypotension, nausea, vomiting, slow heart rate, fever, anemia, paresthesia, headache, itching, and back pain. These are usually mild and short-lived. If the numbness or other side effects persist at the injection site, consult your doctor without delay. Before using Naropin 0.75% Injection, it is very important to tell your doctor if you have any underlying heart disease or are taking medicines for heart rhythm problems. Ask your doctor for advice if you are pregnant or breastfeeding. Also, it is not safe to drive or operate heavy machinery while on medication, as you may feel dizzy.
