Panic attacks after infusion may be caused by adverse drug reactions or by intolerance of the individual’s constitution to the drug. If the infusion speed is too fast, slowing down the infusion speed in time will help to reduce the symptoms. Patients may sometimes be related to their individual constitution and caused by allergy to a certain drug. If this is caused by this condition, the infusion must be stopped immediately and anti-allergy treatment must be given to avoid anaphylaxis. If the panic persists and does not improve, promptly visit the cardiology department for electrocardiogram, ambulatory electrocardiogram and other tests, and treat the symptoms according to the specific test results, which can help to improve the symptoms.
