Clozapine 79-88 prolactin Homo sapiens 122-131 11561931-8 2001 The mean +/- SD serum prolactin level was 8.42+/-4.17 ng/mL for clozapine monotherapy patients and 35.76+/-17.43 ng/mL for combination therapy patients. Clozapine 64-73 prolactin Homo sapiens 22-31 11561931-11 2001 CONCLUSION: The combination of risperidone and clozapine appears to result in a moderate elevation of serum prolactin levels. Clozapine 47-56 prolactin Homo sapiens 108-117
