I tapered off and stopped risperdal. Other med is working as mood stabilizer. Amenorrhea since starting on risp. Period has lasted 2 weeks+ seek help?

Can happen. Risperdal can stimulate prolactin secretion (from the pituitary gland in the brain) to high levels in some patients. If this was your case, it may take a month or more after discontinuation for your hormones to balance and cycles to regulate. Your other meds may impact as well. If bleeding continues, please see your doctor.
