Seek emergency care for severe breathing difficulty, new confusion, a seizure, fainting, sudden weakness, or rapidly worsening illness.
Contact the treating clinician promptly if symptoms return during or after treatment, a skin lesion enlarges, bone pain develops, or medicine side effects make it difficult to continue therapy.

Keep scheduled appointments even if you feel well, since laboratory monitoring can identify problems before they cause noticeable symptoms.
