I started on sertraline about two weeks ago and I'm not feeling any different yet. My doctor said to give it time, but I'm wondering if I should expect to feel better soon or if this is normal. How long did it take for you to notice changes?
Sertraline takes a frustrating amount of patience - you're right on schedule feeling nothing yet, and that's actually the annoying normal! The neurochemistry stuff needs time to settle, and most people hit that "wait, I think I feel better?" moment somewhere between week 4 and 8, sometimes even longer.
One thing that helps: keep a stupid simple daily mood log, even just a number 1-10 when you wake up. You won't feel the shift happening in real time, but when you look back at week 2 versus week 6 you'll actually see the trend even if it doesn't feel dramatic day-to-day. Your brain gets used to small improvements and forgets they're improvements, so having that written proof is huge.
Most people don't notice real changes from sertraline until 4-6 weeks in, sometimes longer, so two weeks is still early. Your doctor's right to say give it time - it's frustrating to wait but that's pretty standard for how SSRIs work, and jumping to conclusions too fast can lead to unnecessary dose changes or switching meds when the first one just needed more time.
Two weeks is genuinely early - your body's still in the adjustment phase. The standard timeline most doctors cite is somewhere between 4 to 8 weeks before you start noticing a real shift in mood or anxiety levels, and for some people it takes even longer than that. What often happens first is subtle stuff you might not immediately connect to the medication: sleeping a bit better, or noticing you didn't catastrophize about something that normally would've sent you spiraling. Those small wins can feel invisible at first.
The frustrating part is that sertraline needs time to build up in your system and for your brain chemistry to actually rebalance. During weeks 2-3, side effects sometimes feel more noticeable than benefits, which makes the wait feel pointless. But your doctor's advice to stick with it is solid. If you hit the 6 or 8 week mark and genuinely feel nothing has shifted - no improvement in sleep, appetite, or baseline anxiety - that's when you'd typically loop back and discuss whether the dose needs adjusting or if a different medication might work better for you.
One thing worth tracking is whether your appetite, sleep quality, or ability to focus on tasks has changed, even if your overall mood hasn't felt dramatically different yet. Sometimes the emotional relief lags behind those physical changes. Keep your doctor in the loop about how you're feeling, and don't hesitate to reach out if you notice anything concerning or if the side effects become rough. But purely in terms of whether you're doing it wrong by not feeling better at two weeks - you're not. This is exactly where everyone lands at this point.
The window you're in right now - two to three weeks - is where a lot of people start second-guessing whether anything's happening at all, and that's when it actually matters most to stick with it. I had a similar stretch of feeling completely flat on the same medication, convinced it wasn't doing anything, but around week five or six I realized I'd stopped dreading mornings and wasn't spiraling over small stuff anymore. The shift wasn't dramatic, which is maybe why I almost missed it.
Your doctor's being straight with you - two weeks just isn't enough time for sertraline to settle in your system properly. I know someone close to me who didn't notice anything until week five or six, and then it was like a switch flipped, so the patience part really does matter even though it's annoying as hell.
