SSRIs (selective serotonin reuptake inhibitors) are the most commonly prescribed antidepressants. Millions use them for depression, anxiety, OCD, panic attacks, and PTSD. They don’t act like a quick fix—most people notice steady improvement over 2–6 weeks. That slow start is normal, so hang in there and keep your doctor in the loop.
SSRIs raise serotonin levels in the brain by blocking its reabsorption into nerve cells. That helps mood, sleep, and anxiety over time. The usual names you’ll see are fluoxetine (Prozac), sertraline (Zoloft), paroxetine (Paxil), citalopram (Celexa), and escitalopram (Lexapro). Each drug has small differences in side effects, drug interactions, and dosing—so the best choice depends on your symptoms and medical history.
Common side effects include nausea, headaches, sleep changes, and sexual side effects. Most ease after 1–3 weeks. Watch for worsening mood or suicidal thoughts, especially in people under 25—call your prescriber or local emergency services if that happens. Don’t mix SSRIs with MAOIs or certain migraine or psychiatric meds without checking with a prescriber—serotonin syndrome is rare but serious.
Stopping an SSRI suddenly can cause withdrawal-like symptoms: dizziness, flu-like feelings, or irritability. Taper slowly under medical supervision to avoid this. If pregnancy or breastfeeding is a concern, discuss risks and benefits—some SSRIs are safer than others depending on timing and dose.
Practical tips: take your pill at the same time each day, track side effects in a notebook, and give each medication at least 4–6 weeks before deciding it doesn’t work. If sleep is a problem, some SSRIs make you sleepy and others boost energy—ask your doctor which fits your routine. If sexual side effects are limiting, there are workarounds like dose changes, switching drugs, or adding treatments—don’t stop on your own.
Not seeing benefit or worried about side effects? There are alternatives. Options include other antidepressant classes, medication combos, or non-drug routes like CBT. Our article "Exploring Alternatives to Fluoxetine" covers newer options and trade-offs.

Bottom line: SSRIs help a lot of people, but they require patience and care. Keep clear notes, communicate with your prescriber, and don’t stop suddenly. If you have questions about interactions, pregnancy, or switching meds, ask a trusted clinician and use reliable sources.
