Rarely, serious allergic reactions such as shock may occur after administration; hence, symptoms should be closely monitored, and if any abnormality appears, administration should be stopped immediately, and appropriate treatment should be sought. Allergic symptoms such as swelling around the face or eyes, rashes, or itching may occur, in which case administration should stop, and the medical facility should be notified.
