When you're new to psychiatric medication, the names can feel overwhelming — SSRIs, SNRIs, mood stabilizers, atypical antipsychotics, stimulants. What's the difference? Why does your friend with anxiety take the same medication as someone you know with depression? Why would a doctor prescribe an antipsychotic to someone who doesn't have psychosis? These questions have good answers, and understanding them can make the treatment process feel a lot less opaque. Sindhia Shyras, APRN is a board-certified Psychiatric Nurse Practitioner with over nine years of clinical experience. She sees Stratford-area patients via telehealth across Connecticut and in-person at 1 Liberty Sq, Ste 301, New Britain, CT 06051.
Selective serotonin reuptake inhibitors (SSRIs) — medications like sertraline, escitalopram, and fluoxetine — are first-line treatment for depression, generalized anxiety disorder, panic disorder, OCD, and PTSD. They work by increasing serotonin availability in the brain, and they're generally well-tolerated with a manageable side effect profile. SNRIs like venlafaxine and duloxetine add norepinephrine into the mix, which can be particularly helpful for anxiety and for physical symptoms like chronic pain. These are often the starting point for mood and anxiety conditions — not because they're a default, but because the evidence for them is strong.
Mood stabilizers — lithium, valproate, lamotrigine, and some others — are used primarily for bipolar disorder, where the problem isn't just low mood but dramatic swings between extremes. Lithium has been used for decades and has a strong evidence base for preventing both manic and depressive episodes in bipolar I disorder. Lamotrigine is particularly useful for the depressive phases of bipolar II. These medications require different monitoring than antidepressants — some need regular blood draws to check levels or organ function — but they're the right tool when you're managing a condition that's fundamentally about regulation rather than elevation.
Atypical antipsychotics like quetiapine, aripiprazole, and risperidone have a broader range of uses than their name suggests. They're used as augmentation for depression when antidepressants alone aren't enough. They're used to help with sleep in some cases. They're used in bipolar disorder, PTSD, and certain severe anxiety conditions. The name "antipsychotic" makes people nervous, but these medications operate on dopamine and serotonin pathways in ways that are useful across multiple diagnostic categories. Sindhia will always explain why a particular medication is appropriate for your situation — not just hand you a prescription you don't understand.
