Sertraline (Zoloft)
This is general information to help you ask better questions. It is not medical advice. Your prescriber knows your full picture. Never stop or adjust an antipsychotic without medical guidance — abrupt discontinuation can be dangerous.
Sertraline is one of the most commonly prescribed antidepressants in the world, and in the context of psychosis recovery, it typically appears for one specific reason: post-psychotic depression. The depression that follows a psychotic episode - flat, heavy, and often unlike any depression someone has experienced before - is not well-addressed by antipsychotics alone. Adding an antidepressant is a reasonable and common clinical response.
It may also be prescribed for anxiety, which is a significant feature of many people's recovery experience, or for OCD, which sertraline has particularly strong evidence for.
Sertraline is an SSRI (selective serotonin re-uptake inhibitor). It works by increasing serotonin availability in the brain. Among antidepressants, it has a relatively favorable side-effect profile and fewer drug interactions than some alternatives, which matters when it's being added to an antipsychotic.
An honest note about limitations
Sertraline is good at treating depression and anxiety. It is not an antipsychotic. It will not treat hallucinations, delusions, or disorganised thinking - your antipsychotic is doing that work. The sertraline is for the mood and anxiety that sits underneath. Both matter.
What to expect early on
i. It often feels worse before it gets better. For the first one to three weeks, many people experience increased anxiety, jitteriness, nausea, insomnia, or a sense of activation. This is the most common window in which people stop SSRIs, and also the window where pushing through usually pays off. The early discomfort is not a sign the medication is wrong for you.
ii. Full effect takes four to six weeks. The meaningful antidepressant effect develops gradually. Some people notice changes earlier (sleep, edges of mood, appetite) but the substantive shift typically takes a month or more. Being at week two with no change is expected, not evidence of failure.
iii. Sexual side effects. Among the most common and least discussed. Reduced libido, difficulty with arousal, and difficulty reaching orgasm are common with SSRIs at any dose. These effects tend to persist as long as the medication is taken. Many prescribers don't raise this; many patients don't volunteer it. If it's affecting you, name it; there are options, including dose adjustment or switching to an antidepressant with a different profile.
iv. Sleep effects. Some people sleep better on sertraline; others find it disrupts sleep or causes vivid dreams. Taking it in the morning rather than at night often helps if sleep is affected.
v. Nausea. Particularly in the first week. Taking it with food usually helps. Usually self-limiting.
vi. Emotional dulling, in some people. A subset of people on SSRIs describe a flatness - less depression, but also less of everything else. This is distinct from the depression you started with and worth naming. Sometimes a dose adjustment or a different agent helps.
A specific caution for this population
In a small minority of people, particularly those with a personal or family history of bipolar disorder, or whose psychotic episode had significant mood features, SSRIs can trigger or worsen manic or hypomanic symptoms. This is not common, but it's more relevant in this population than in a general antidepressant context.
Symptoms of activation or mania: racing thoughts, decreased need for sleep with maintained energy, pressured speech, grandiosity, increased risk-taking, a sense of unusual elation or irritability that feels different from your baseline. If any of these appear after starting or increasing sertraline, contact your prescriber promptly. This is the single most important caution for SSRIs in people with a psychosis history.
Worth bringing up sooner
Increased anxiety or jitteriness that hasn't eased by week three
Sexual side effects affecting your life - these are real, treatable, and worth naming.
Any signs of activation or mood escalation - racing thoughts, reduced sleep with high energy, unusual elation.
Emotional numbing that wasn't there before
No meaningful change by eight weeks - a prompt to review the plan.
Less common, but important to know
Serotonin syndrome Rare but serious. Caused by too much serotonin activity, usually from combining SSRIs with other serotonergic drugs. Relevant culprits: certain pain medications (tramadol), migraine medications (triptans), St John's Wort, and recreational drugs including MDMA. Symptoms include high fever, agitation, muscle rigidity, rapid heart rate, sweating, and confusion. This is a medical emergency. The practical takeaway: tell every prescriber and pharmacist you're on sertraline, and avoid St John's Wort entirely.
Discontinuation symptoms Stopping sertraline abruptly, or missing several doses, can cause discontinuation effects: dizziness, 'brain zaps' (an electrical sensation), flu-like feelings, irritability, and a return of anxiety or depressive symptoms. These are real and uncomfortable but not dangerous. Always taper gradually with your prescriber's guidance rather than stopping suddenly.
DON'T WAIT THROUGH THESE: New or worsening thoughts of self-harm or suicide, particularly in the first weeks of starting or increasing the dose. Signs of mania or activation (racing thoughts, no need for sleep, escalating energy, grandiosity). Symptoms of serotonin syndrome (high fever, muscle rigidity, severe agitation, rapid heart rate). Call your prescriber. In the US, call or text 988 at any time.
Things that interact
Other serotonergic medications - tell every prescriber and pharmacist you're on sertraline before anything new is added.
MAOIs - a different class of antidepressant. Cannot be combined; requires a washout period of weeks between stopping one and starting the other.
St John's Wort - a herbal supplement. Combining with an SSRI can cause serotonin syndrome. Avoid entirely.
Tramadol and some other pain medications - increases serotonin syndrome risk.
Blood thinners (warfarin, aspirin at higher doses) - SSRIs can increase bleeding risk when combined.
Alcohol - amplifies sedation and can worsen depression. Some people find any drinking meaningfully interferes with how the medication works.
If you ever come off it
Sertraline should not be stopped abruptly. The standard approach is a gradual taper, often over several weeks, guided by your prescriber. Even if you feel better - especially if you feel better - the right way to stop is slowly and in collaboration with your care team. Stopping because you feel well is reasonable; stopping abruptly is not.
If you're considering stopping because of side effects, bring it to your prescriber first. Side effects often have solutions (dose adjustment, timing changes, switching to a different agent) that don't require stopping entirely.
Worth asking at your next appointment
"How long should we expect before we know if this is working?"
"What are we looking for to know it's working?"
"I'm experiencing [side effect]. Are there ways to address it without stopping?"
"Are there interactions with my antipsychotic I should know about?"
"If this isn't enough, what would we try next?"
This is general information. Your prescriber knows your full picture - use this to ask better questions, not to make changes on your own. Never stop or adjust an SSRI without medical guidance.
