If the operation is done in a regular plastic surgery clinic or hospital, you don't need an anti-inflammatory needle, you can take anti-inflammatory drugs and cephalosporins orally. If it is done in a beauty salon, it is recommended that intravenous injection for three days is safer. You can inject normal saline containing ceftriaxone sodium, vitamin b6 and vc, and do a skin test before injection to avoid your allergy to cephalosporin.
