By the fourth week, the viral load was negative, but the patient reported skin lesions, a change in character, aggressiveness and suicidal thoughts, so both he and his family asked to discontinue treatment and he was referred to psychiatry. In December 2015, the patient came to the clinic with a report from Psychiatry stating that he had not been prescribed any psychopharmaceuticals and that at that time there was no contraindication to starting another HCV treatment.
