After a client has been prescribed fluoxetine (Prozac) for a diagnosis of anxiety disorder, which of the following information should the nurse be sure to include in the client teaching?

Choice A reason: Abruptly stopping fluoxetine, an SSRI, disrupts serotonin levels, causing discontinuation syndrome with symptoms like dizziness and irritability due to rapid neurotransmitter imbalance in the brain. Gradual tapering stabilizes serotonin, preventing withdrawal, making this critical teaching for safe medication management in anxiety treatment. Choice B reason: Constipation is not a common side effect of fluoxetine, which primarily causes nausea or diarrhea via serotonin modulation. Anticholinergic drugs, not SSRIs, typically cause constipation. This teaching is inaccurate, as fluoxetine’s side effect profile does not emphasize gastrointestinal slowing, making it incorrect. Choice C reason: Fluoxetine takes 4-8 weeks, not months, to reach efficacy by increasing serotonin in the prefrontal cortex and amygdala. Overstating the timeline discourages adherence, as patients expect faster relief from anxiety symptoms, making this teaching point scientifically inaccurate and misleading. Choice D reason: Fluoxetine is not addictive, as it lacks the reinforcing GABA effects of benzodiazepines. It modulates serotonin for anxiety without dependence risk. This teaching is incorrect, as it misrepresents fluoxetine’s pharmacological profile, potentially causing unnecessary fear about its safe use in treatment.
