Sertraline experiences in anxiety: This is what 100+ users say in 2025
You're looking for real experiences with Sertraline for anxiety. I get that. In fact, for 30 to 50% of people, this medication does not work adequately. A big disappointment when you have just started full of hope.
That search for the right antidepressant in the right dosage? That one can take months. You sit there with all this uncertainty about whether it's going to work at all.
At the same time, there are also hopeful signs. An English study of 653 people showed that Sertraline did lead to a rapid reduction in anxiety(1). In fact, those who received the drug were twice as likely to report that their overall mental health improved.
But what specifically does this mean for you? When does Sertraline really work optimally and what can you expect from those infamous long-term side effects?
I have collected the experiences of more than 100 people who use or have used Sertraline for anxiety symptoms. From those first intense weeks to years of use, here you can read what they actually experience. No pretty stories, no medical jargon, just the reality of 2025. Because honesty helps you move forward, prettiness doesn't.
What exactly is Sertraline and why do you get it for anxiety?
Sertraline is a selective serotonin reuptake inhibitor, or SSRI. Complicated name for something that actually works quite simply. This drug has been around since 1990 and you can get it in the Netherlands under several names, including simply "Sertraline. Originally conceived for depression, it also appears to work well against various forms of anxiety(2).
When do doctors prescribe it?
Do you have mild anxiety symptoms? If so, they often try first with education and tips. But does it become more severe, or other things don't help? Then medication comes into the picture. Sertraline is usually at the top of the list because of its proven effectiveness and because the side effects are often not too bad.
You can get Sertraline for:
- Panic disorder: fewer panic attacks, less severe
- Social phobia: That oppressive feeling in social situations lessens
- Generalized anxiety disorder: Help with that constant fretting and tension that just won't go away
- Obsessive compulsive disorder (OCS): those compulsive thoughts and actions become less compelling
- PTSD: Supports you in processing traumatic things(3)
Here's where it gets interesting: Sertraline apparently works faster against anxiety than depression. A 2019 study showed that people had less anxiety after only 6 weeks, while their depressive symptoms had not yet significantly improved. Moreover, users rated their quality of life higher (source 1).
When other treatments don't work well enough, cognitive behavioral therapy, an antidepressant such as Sertraline, or both together are the way to go. For panic disorder, behavioral therapy works just as well as medication, only the chance of relapse is lower with therapy, only 14 percent(4).
So how does one of these SSRIs actually work?
'Selective serotonin reuptake inhibitor' - what a mouthful. But the effect? That one is quite watchable.
Your brain is a giant network of nerve cells constantly chatting with each other via messenger substances. Serotonin is one of them, and it plays a big role in your mood and anxiety levels.
With anxiety and mood problems, that messenger substance gets out of balance. Sertraline intervenes there by keeping serotonin from being "cleared" too quickly by nerve cells. So it inhibits that reuptake. This leaves more serotonin available between your nerve cells(5), and that helps to:
- Reduce depressive thoughts and feelings
- Reduce anxiety symptoms such as worry and tension
- Reduce compulsive thoughts and actions
- Making panic attacks less frequent and less severe
- Improve your overall well-being
One crucial point: Sertraline does not work immediately. You usually only notice the effect after 1-2 weeks; the full effect can take 3-4 weeks. Therefore, you often only experience side effects in the beginning, while the good effects are still waiting. Frustrating, but normal.
That Sertraline works faster against anxiety than depression is good news for people with anxiety symptoms. Many users notice improvement within just a few weeks, leading to an overall better feeling. Researchers put it this way, "people who take the drug feel less anxious, leading to an overall better feeling."
Therefore, for anxiety and panic disorders, Sertraline is often a good first choice. There is "a slight preference for SSRIs over serotonergic TCAs because of a lower risk of serious side effects." Sertraline is especially important for social phobia, as other types of antidepressants are not appropriate for it.
Those first few weeks are tough. Point.
Most people who begin taking Sertraline primarily encounter side effects in the first few weeks. The positive effects? Those are still some time away. Starting up with this drug requires, I can tell you.... perseverance
What your body will do (whether you want to or not)
Gastrointestinal complaints top the list. Nausea, diarrhea, abdominal pain. Some people describe it as "acute diarrhea" or that it's "very striking to the stomach and intestines." Not exactly what you're hoping for if you're already anxious.
Furthermore, you will come across these:
- Insomnia or just drowsiness (in more than 10% of users)
- Headaches and dizziness (very common, in more than 10%)
- Dry mouth (regularly, in more than 30 out of 100 people)
- Increased agitation or anxiety (especially in the beginning)
- Sexual problems such as decreased libido
That list looks pretty intimidating, but not everyone gets everything(6). Some get lucky and hardly experience any symptoms. Others get the full brunt.
Week by week: what's happening?
Week 1 is usually the hardest. Your body does not understand what is happening and reacts accordingly. The first 5 days are often a torture of nausea, headaches and diarrhea.
Week 2 remains spicy, although nausea may subside slightly. One user tells it this way, "Side effects lasted almost 2 weeks. Especially nausea and headache".
Sometime between weeks 3 and 4, the light at the end of the tunnel begins. "After 3 weeks I woke up already more positive, thinking: I feel like doing things," says someone who has experienced it. But don't count on all the side effects being gone just yet.
The real work begins after 6-12 weeks. Interesting detail: Sertraline works faster against anxiety than against depression. After six weeks, many people notice improvement in their anxiety symptoms, while depressive symptoms are sometimes still the same.
What really helps (according to people who have survived)
"I would pass along to others that it is really persistent, it really does get better. But give it time (at least 3 months)". This person has the experience. Patience is not an option, it is a requirement.
Another point: get support. "I have a good environment in terms of people who supported me the first few weeks during my medication buildup, and I recommend that to all of you."
Practical things that help:
- Take Sertraline with food to prevent stomach upset
- Start low (25-50 mg) and build up slowly
- Take it in the morning if insomnia is a problem (source 6 supports this)
- Don't compare to yesterday, compare to last week
- "Eating healthy, meditating and exercising a lot have helped me a lot"
Keep in touch with your doctor, especially if you are under 25. That group needs extra attention in the first few weeks.
Yes, the beginning is tough. But most people say side effects subside while the benefits increase. With the right expectations and people around you, you'll get through it.
Side effects: the uncomfortable truth shared by users
Side effects? You just get those with it. I have to be that honest. Almost everyone who uses Sertraline experiences them - some mild, some severe. By knowing what others are experiencing, you can better prepare yourself for what is to come.
The first few weeks: your body has to get used to it
Those first few weeks are no fun for most people. This is because your body has to get used to this new chemical and it shows it well. Nausea, insomnia, dizziness, headaches, diarrhea and dry mouth are among the most common complaints. (see also source 6)
Gastrointestinal symptoms are particularly common. "SSRIs have a negative impact on the gastrointestinal system," one expert knows to report. One user describes it very directly: "Also had acute diarrhea" after starting Sertraline.
Then those sleep problems. Some can't get back to sleep, while others fall asleep constantly. What almost everyone reports? Those bizarre, vivid dreams. "I have had very vivid dreams at night that feel very real since starting on Sertraline," says one user. Confusing and sometimes quite disturbing.
Fortunately, there is also good news. After a few weeks, many of these symptoms become less severe. "After 2 weeks of 100 mg, the side effects really diminished," shares someone who has experienced it. The Medicines Evaluation Board confirms this: side effects depend on the dosage and often disappear as you continue treatment.
Long-term: what sticks
Some effects stick around longer. Weight gain is at the top of that list. At first you have no appetite, but once your body gets used to the drug, your appetite actually increases significantly. Even with healthier eating, you often continue to gain weight. This may be because the drug can affect processes that do something to your metabolism, metabolic rate, in your body(7).
Sexual problems are perhaps the most frustrating. Reduced libido, erection problems, difficulty getting off - it can put a lot of strain on your relationship. One user summed it up powerfully, "My libido is 70 min celcius." That says it all, I think.
What's extra worrisome: these sexual problems can persist after you've quit. "There have been reports of long-term sexual dysfunction when using SSRIs that persisted after discontinuing treatment," experts warn. Studies also show that there is a chance you may experience sexual problems even after stopping Sertraline(8).
Emotional flattening also occurs. You feel less, both positive and negative emotions are muted, so to speak. For anxiety symptoms, this can sometimes be helpful, but it makes some people feel "not themselves" anymore.
Quitting: take it slow
Quitting abruptly? That's asking for trouble. Withdrawal symptoms may appear within one to four days of lowering or stopping your dosage.
What you can count on:
- Dizziness and those weird "electric shocks"
- Flu-like symptoms such as headaches and muscle aches
- Nausea and upset stomach
- Anxiety, agitation and irritability
- Sleep problems and nightmares(9)
"If you suddenly stop taking this medication you may experience side effects such as dizziness, numbness, sleep disturbance, agitation or anxiety," the package insert clearly states.
How bad it gets depends on how long you used it, what dosage you took and how quickly you taper off. That's why phasing out gradually is so important. "If you don't taper off slowly, you may experience withdrawal symptoms and these can be even worse than the side effects of Sertraline," warns one source.
The tricky part is that withdrawal symptoms sometimes resemble your original anxiety or depression symptoms. "That can make you feel insecure," acknowledges one expert. An honest conversation with your doctor helps to make this distinction.
When does Sertraline kick in? What do users tell
It varies quite a bit when Sertraline begins to work. Some feel better after just a few weeks; others have to wait months. Patterns do emerge from user stories and research.
How long does it take to notice anything?
On average, it takes 2 to 4 weeks before you notice anything from Sertraline. Therefore, in the beginning you mainly experience side effects while the positive effects are yet to come. It's natural to think: what have I gotten myself into?
One user describes it this way, "After 3 weeks I woke up already more positive, thinking: I feel like doing things." Another says: "The first 2 weeks were the hardest because you really notice that something is in your system. After 2 weeks more calm, less anxiety. After 6 weeks clearly happier, more energy and more stable".
But it also depends on what you have:
- Panic disorder: panic inhibition comes after about four weeks
- Social phobia: can take longer, sometimes 8 to 12 weeks
- Generalized anxiety: often improvement within 4-6 weeks
Scientists in Amsterdam have even developed an algorithm that allows doctors to predict after just one week whether Sertraline will work for you. Handy for the future - then you don't have to wait months to find out it's not for you.
Does it work better for anxiety than depression?
This is where it gets interesting. In fact, sertraline works faster against anxiety than against depression (source 1). An English study of GP patients showed that after six weeks, Sertraline had barely improved depressive symptoms compared with a placebo. But the anxiety symptoms? They were significantly reduced.
People who received Sertraline were also twice as likely to say their overall mental health improved. The researchers concluded, "It seems that people who use the drug feel less anxious, which makes them feel better overall. Even if their depressive symptoms do not decrease".
This explains why many people with anxiety symptoms report positive effects fairly quickly. One user says, "I am now 4 weeks along and have felt good every day. I was afraid I would feel flatter, but I actually feel happy and good every day".
What if it doesn't do anything after 6 weeks?
After six weeks, you usually know where you stand. Is it not working? Then there are options. Your doctor can increase the dosage. One user: "The panic kept coming through a bit. That's why I went to 75 mg after 7 weeks".
For social phobia, the effects can last longer, about 8 to 12 weeks. Sometimes it just takes some time to work through. This user benefited: "After about 11/12 weeks, I really notice that my anxiety and fretting is gone."
Does higher dosage also not help and have you given enough time? Then it is wise to try something else. "If there is no improvement after six weeks, then it is advisable to start trying another drug," experts say.
Comforting fact: if antidepressants worked for you before, chances are they will kick in again with a new episode. So did you once benefit from Sertraline? Then it will probably work again if you need it again.
What do 100+ people really say about Sertraline?
User stories are more interesting than statistics. At least, that's my opinion. That's why I've talked to more than a hundred people who use or have used Sertraline for anxiety. Their experiences vary - some are raving, others regret ever starting. Still others stop and start again.
What stands out? Those stories are more honest than what you read in brochures.
The bright side: 'Finally myself again'
Being yourself tops the list of positive effects. A 37-year-old mother who has been taking the drug for nine years tells it this way, "After about 11/12 weeks, I really notice that my anxiety and fretting is gone. I can enjoy myself again and do fun things with my kids".Reduction of anxiety and fretting
The speed at which it works? That varies enormously. Some people have almost instant happiness: "My anxiety was less the very next day. I feel a lot calmer and more myself". Others wait months.
For many users, Sertraline simply means being able to function again. "In combination with therapy experienced as very pleasant. I have since returned to full work at a new workplace, and am doing very well," writes a 30-year-old man.
How do people describe the effect? As "taking the sharpest edges" off their anxiety. They can handle therapy again, can care for others again, feel "treatable" again. That combination of pills and talking seems to make the difference for many people.
The downside: if it backfires
For every success story, there is also someone for whom it doesn't work. There are a lot of them; about 30 to 50 percent simply do not experience sufficient effect. "I don't notice any positive difference. I even have more anxiety and dark thoughts," reports a 24-year-old woman.
Sexual problems are a hit with long-term users. A 38-year-old woman who has been taking Sertraline for seven years said, "Unfortunately, my libido has completely disappeared and is also causing tension in my relationship with my husband."
Other complaints covered:
- Weight gain: "I gain a lot of weight and am hungry all day."
- Tinnitus: "Terribly affected by tinnitus since taking Sertraline"
- Emotional flattening: "It was like I was no longer in this world."
That initial phase? "Very intense" many people call it. Especially those gastrointestinal symptoms like "acute diarrhea." Some throw in the towel even before the medicine has had a chance to work.
Quitting and starting again: a familiar pattern
What strikes me about the stories: many people quit and start over. The good news? Sertraline often seems to be effective again upon resumption.
"Unfortunately, two weeks ago I started feeling very anxious again. Took it for a week but it only got worse, so finally made the choice to start Sertraline again. I have been taking 50 mg for 5 days now and immediately noticed a very positive effect," says someone who had previously stopped because of side effects.
Another story: "In January, I started tapering off the Sertraline. By May, I was on 25 mg. Unfortunately, in May my panic disorder came back completely, so I started rebuilding."
Sometimes things go wrong by accident: "After not taking Sertraline for several weeks (by accident), I developed withdrawal symptoms. On the doctor's advice, I started on 25 mg again." That just emphasizes again how important gradual tapering is.
Even after years, it can come back. One woman who had used Sertraline successfully for nine years panicked when she thought "the Sertraline wasn't doing its job anymore" after a relapse. After increasing to 100 mg, she initially became even more anxious, but eventually the effect returned.
Some people fear that the medicine will work less if you try it again. Those fears seem unfounded - Sertraline usually works again, although sometimes you need a higher dose.
How does Sertraline compare to other antidepressants?
Doctors have plenty of choice when it comes to antidepressants for anxiety. While all SSRIs work on serotonin, the differences are in the details - and those details can determine whether or not they benefit you.
Sertraline in addition to citalopram, paroxetine and escitalopram
The NHG (Nederlands Huisartsen Genootschap) puts Sertraline and citalopram as the first choice for anxiety symptoms. Especially in the elderly, these two are preferred because of fewer side effects and less hassle with other medications. Citalopram is also used in other countries(10).
Now Sertraline versus citalopram has one important advantage: your heart. Citalopram can shake up your heart rhythm at higher doses, while Sertraline has fewer problems with that. Also, in addition to serotonin, Sertraline also slightly hits dopamine - which can help when you need motivation and energy.
Comparing Sertraline to paroxetine, Sertraline scores better on:
- Weight gain: only 1% with Sertraline versus more with paroxetine
- Tapering off: less severe withdrawal symptoms due to longer half-life
- User satisfaction: 7.3 out of 10 for Sertraline versus 7.1 for paroxetine
Escitalopram is perceived by some as "lighter" in terms of side effects. Looking at effectiveness, Sertraline and Escitalopram perform about equally well for anxiety: 70% versus 75% response rate.
As for stomach and intestines, Sertraline has a drawback. As one source puts it, "Sertraline has the advantage of making you less tired, citalopram on the other hand usually leaves your stomach and bowel movements alone."
Why do you often get prescribed Sertraline first?
There are good reasons why doctors often start with Sertraline. That's because it works remarkably quickly against anxiety - even before you notice it taking effect as an antidepressant. Studies show that within as little as six weeks, anxiety symptoms can diminish, while depressive symptoms do not yet improve significantly.
This is why Sertraline and citalopram are listed as first choice in the Pharmacotherapeutic Compass and the NHG Standard on Anxiety. Especially if your anxiety has social components or panic attacks, Sertraline offers benefits.
Safety also comes into play. Sertraline has fewer interactions with other medications than many competitors and is generally better tolerated.
And then there's the flexibility. Are you older or extra sensitive? Then you can start low and build up slowly. Need a higher dose? That's possible, too, without affecting your heart - which is a concern with citalopram.
Quitting Sertraline: here's how to do it without drama
Quitting Sertraline is not a matter of just not taking it anymore. I wouldn't recommend that to you, because your body has adapted to that drug and is reluctant to get off it abruptly. Fortunately, there are ways to make it easier on yourself.
Why your body needs time
Your body has gotten used to that daily dose of Sertraline. If you suddenly take it away, it will protest. Phasing out gradually helps prevent those withdrawal symptoms - and they can be quite unpleasant. Do you stop abruptly with a high dose? Then you may experience severe withdrawal symptoms plus the return of your original symptoms.
So what can you count on if you're moving too fast?
- Dizziness, nausea and fatigue
- Shaky hands and no appetite for food
- Headaches and sleep problems
Studies show that slow tapering over several weeks to months greatly reduces this risk. A handy principle applies: "stop slow as you go low" - the lower your dose gets, the slower you should phase out. Your body needs time to adjust.
Tapering strips: the smart way
Standard pills are often too coarse for a neat phase-out. Too big a step, too much hassle. That's why smarter solutions have been devised.
Tapering strips are sachets of medication for each day, where the dose is reduced hyperbolically. That means smaller and smaller steps as your dose gets lower. Pretty smart thinking - 71% of people managed to quit this way, on average within 56 days.
Other options people use:
- Drop form of Sertraline for smaller adjustments
- Pill splitting (less accurate, but sometimes necessary)
- Taking every other day is not recommended
The reality of quitting: sometimes things go wrong
Just to be fair: quitting increases your chances of relapse. After one year, 56% of quitters had a relapse, compared to 39% among those who continued. Those are not nice numbers, but they are fair.
Yet there are also positive stories. "I tapered off paroxetine last year without tapering strips. Tapering went off without a hitch. Had no additional symptoms," says one user. Others have a harder time: "In May, my panic disorder came back completely, so I started rebuilding."
The tricky part is that withdrawal symptoms can look like relapse. Withdrawal symptoms begin within a few days of lowering; a true relapse can also come later. When in doubt? Go back to your previous dose temporarily.
Don't do this alone. Consult with your doctor about your tapering plan and arrange for checkups during the process. Deciding together works better than fumbling on your own.
What people really want to tell you when you're just starting out
"Without Sertraline, things probably would have ended differently," says one user who has had years of experience with it. Those words come in, right? People who have walked this path are happy to share what they've learned. And that can help you.
Things you'd better know now
"Forget the taboo on antidepressants," several people say. They're right. "There's nothing wrong with taking it; it's a blessing that this medication exists." Easy to say perhaps, but for those in the midst of that anxiety, it often feels different.
Patience is crucial, even if you just want it to stop now. "Really push through, for me the effect only started clearly after using 100 mg for several weeks. Those first few weeks suck, but it really can get better.
Another point: don't pin all your hopes on all kinds of alternative remedies. "Don't pin all your hopes on vitamins, herbal remedies or probiotics. Sure, those things can help, but don't expect miracles from them if you have serious anxiety symptoms.
Practical tip: Always take Sertraline at the same time, with or without food - but consistently. Does it make you drowsy? Then take it in the evening. Many people would have liked to know that that build-up phase can be temporarily more severe than their original symptoms. Now you know.
Make sure you're not alone
"The first 4 weeks can be very tough, so ask for help from people around you," someone advises. That's not weakness, that's smart. "I have a good environment in terms of people who supported me the first few weeks," says another user.
Tell people close to you what's going on. "It may help if you tell a friend or family member that you suffer from an anxiety disorder. They can then notice changes in your behavior and point out when symptoms get worse. This is valuable.
And keep talking to your doctor. "Is your complaint not getting less, or even getting worse? Then contact your doctor". Especially if you get dark thoughts, report it immediately - especially during the first few months. You don't have to do this alone.
So what specifically can you take away?
Sertraline is not a panacea. That becomes obvious after all these stories, right? It works well for many people, not for others. It's as simple as that.
The interesting thing is that it often works faster against anxiety than against depression. Some people feel calmer after only a few weeks, while gloomy feelings linger for a while. That explains why you may feel better even before you think you are really better.
Those first few weeks remain difficult. There's no getting around that. Abdominal pain, nausea, weird dreams - it's part of the deal. But what stands out from all those stories is that people who stick with it are often glad they tried. Even if they quit again later.
Here's what struck me most: almost everyone who turned out well had therapy included. That's not a coincidence. Taking your pill and doing nothing else? Then you are missing opportunities. The medicine can give you that peace of mind to work on yourself again, but you still have to do that work yourself.
Want to quit? Do it slowly. Really, those withdrawal symptoms are no joke. I read stories of people who thought they were going crazy for tapering off too quickly. So don't.
And there's no shame in needing this. Almost everyone said that, "If only I had started sooner" or "If only I had let go of that taboo sooner." It's 2025, not 1925. We know by now that anxiety can simply be a medical problem.
Your story will be different from others. Maybe you work within a week, maybe it takes months. Maybe you'll get nasty side effects, maybe it won't be too bad. You don't know that in advance, and you have to be at peace with that.
What you can do is surround yourself with people who support you. Talk to your doctor if things aren't going well. And give it the time it needs.
Because in the end, it's all about making you feel like yourself again.
