The nurse practitioner (NP) is treating a 22 year-old for depression with high dose fluoxetine. After several months of dosage changes, she is finally doing well and comes today for a follow up visit. She is happy and states that she might be pregnant. A urine test indicates pregnancy. The NP has referred the patient to an obstetrician who will see the patient in 4 weeks. How should the fluoxetine be handled today?
