Psychiatric medications can feel overwhelming for nursing students preparing for the NCLEX, but breaking them down into simple categories makes them easier to remember. Every nurse, whether a new graduate or an experienced registered nurse, will encounter psych meds in practice—so knowing the essentials of SSRIs, lithium, and antipsychotics is a must. This guide serves as a quick nursing reference and complements any nursing bundle of study resources.


🌿 SSRIs (Selective Serotonin Reuptake Inhibitors)

Examples: Fluoxetine (Prozac), Sertraline (Zoloft), Escitalopram (Lexapro).
