Go home and rest. It’s not unusual to be tired after treatment. It might be a good idea to have a friend drop you off and pick you up—or stay and keep you company. If you have any symptoms of an injection- or infusion-related reaction, get medical help right away.
You will be given medicines, like an oral corticosteroid, to take once you go home to help reduce the risk of delayed reactions. If you have a history of breathing problems, such as chronic obstructive pulmonary disease (COPD), you may be given additional medicines, such as bronchodilators or inhaled corticosteroids.
