When you start taking an antidepressant, a medication prescribed to treat depression and some anxiety disorders by balancing brain chemicals like serotonin and norepinephrine. Also known as antidepressive drugs, they help millions feel more like themselves—but they don’t come without trade-offs. Not everyone gets side effects, but if you do, they’re usually mild and temporary. Still, knowing what to expect can save you from panic, confusion, or even stopping your medicine too soon.
Common SSRI side effects, a class of antidepressants that increase serotonin levels in the brain. Also known as selective serotonin reuptake inhibitors, they include drugs like sertraline and fluoxetine include nausea, drowsiness, dry mouth, and sexual problems like low libido or trouble reaching orgasm. These often fade after a few weeks. But some people get more serious reactions, like serotonin syndrome, a rare but dangerous condition caused by too much serotonin in the body, often from mixing antidepressants with other drugs or supplements. Also known as serotonin toxicity, it can cause confusion, rapid heartbeat, high fever, and muscle rigidity. If you notice these signs, seek help immediately. Another issue is antidepressant withdrawal, a set of physical and emotional symptoms that happen when you stop taking the medicine too quickly. Also known as discontinuation syndrome, it can cause dizziness, brain zaps, irritability, and flu-like feelings. That’s why you never quit cold turkey—even if you feel better.
Some side effects are easy to miss. Blurred vision from certain meds, trouble sleeping, or sudden weight gain might not seem connected to your antidepressant—but they are. And while some people worry about emotional numbness or feeling "flat," that’s often a sign the dose needs adjusting, not that the drug isn’t working. The key is tracking what happens and talking to your doctor early. You’re not being dramatic—you’re being smart.
