Honest information about antipsychotic side effects — what's common, what's serious, and what to do.
Stopping antipsychotic medication is rarely simple. This guide covers discontinuation symptoms, supersensitivity, relapse risk, and how to taper safely with a clinician.
Side effectsSome antipsychotics produce vivid dreams or nightmares — sometimes intense enough to disrupt sleep. Here is the mechanism and what helps.
Side effectsSome antipsychotics lengthen the QT interval on ECG enough to raise the risk of dangerous arrhythmias. Here is which agents matter, and what monitoring looks like.
Side effectsPeripheral edema — swelling of the lower legs and feet — is an uncommon but recognised antipsychotic side effect. Here is the differential and what to do about it.
Side EffectNeuroleptic malignant syndrome (NMS) is a rare but potentially fatal reaction to antipsychotic medication. Recognising the warning signs early can save a life.
Side effectsMetabolic syndrome is the cluster of risk factors — abdominal weight, glucose, lipids, blood pressure — that drives cardiovascular disease. Antipsychotics push every one of them in the wrong direction.
Side effectsPersistent stuffy nose on an antipsychotic is usually not allergy or infection — it is alpha-1 receptor blockade dilating nasal blood vessels. Here is the workup and treatment.
Side effectsSome antipsychotics raise diabetes risk even in patients who do not gain weight. Here is the mechanism, the monitoring, and the management.
Side EffectQT prolongation is a heart-rhythm risk associated with some antipsychotics. Most cases are clinically silent, but the risk is real and worth understanding for monitoring decisions.
Side effectsAntipsychotics impair sweating and the brain's temperature regulation, raising heat-stroke risk in hot weather. Here is the practical playbook for staying safe in summer.
Side effectsAntipsychotic weight gain is biological, predictable, and partly preventable. Here is what is happening at the receptor level and what actually works to limit it.
Side EffectLightheadedness or fainting on standing is a common — and underrecognised — side effect of several antipsychotics. The good news: it usually responds to simple measures.
Side effectsSome antipsychotics — especially the older phenothiazines — make your skin dramatically more sensitive to sunlight. Knowing this prevents painful sunburns and lasting skin damage.
Side effectsSexual side effects are among the most common reasons people quietly stop their antipsychotic. They are also among the most treatable when named.
Side EffectConstipation from antipsychotics is more than an inconvenience — with clozapine in particular it can progress to ileus and bowel obstruction. Daily prevention is the key.
Side EffectTardive dyskinesia (TD) — involuntary movements caused by long-term antipsychotic use — is one of the most feared side effects of these medications. New treatments have changed the picture significantly.
Side EffectWeight gain is the most common reason people stop their antipsychotic — and one of the most preventable. Here's what actually works.
Side effectsOrthostatic hypotension — a drop in blood pressure on standing — is common when starting many antipsychotics. Here is the mechanism, the risks, and a practical playbook.
Side EffectMovement side effects of antipsychotics — known as extrapyramidal symptoms or EPS — come in four main types. Each has its own warning signs and treatments.
Side effectsSome antipsychotics raise prolactin levels enough to cause symptoms — from missed periods and breast tenderness to long-term bone loss. Here is what to monitor and what to do.
Side EffectDry mouth from antipsychotics seems minor but can damage teeth, disrupt sleep, and worsen quality of life. Active management — and dental care — make a big difference.
Side EffectPeople with schizophrenia die 15–20 years earlier than average — mostly from heart disease. Antipsychotic-related metabolic effects are the biggest modifiable cause.
Side effectsConstipation is one of the most underestimated antipsychotic side effects. On clozapine in particular it can rarely become life-threatening. Here is what to do — and when to worry.
Side effectsClozapine is the most effective antipsychotic for treatment-resistant schizophrenia — and the only one that requires blood monitoring for life. Here is what the REMS program is, and where it is heading.
Side EffectAkathisia is a hard-to-describe inner restlessness — a need to move that is impossible to satisfy. Recognising it early matters; it is treatable and is linked to suicide risk if missed.
Side effectsUrinary hesitancy and incomplete emptying can be a quiet but important side effect of antipsychotics, especially those with anticholinergic activity. Here is what to know.
Side EffectSedation is so common with antipsychotics that it is often confused with the illness itself. Knowing which drugs sedate most — and how to manage it — can transform daily life.
Side effectsNMS is rare — but when it happens, hours matter. The full clinical picture, the differential, and what re-introduction of antipsychotics looks like afterward.
Side effectsBlurred vision on antipsychotics is usually a temporary anticholinergic effect on the eye's focusing muscle — but a small number of vision changes need urgent evaluation.
Side EffectSexual side effects from antipsychotics are very common and very under-discussed. They are usually treatable — but only if patient and prescriber are willing to have the conversation.
Side effectsAkathisia is one of the most distressing antipsychotic side effects — and one of the most under-recognised. Knowing what it feels like is the first step in getting it treated.
Side effectsDry mouth from antipsychotics is annoying but also a real risk for tooth decay. Here is what causes it and a practical menu of things that help.
Side EffectSeveral antipsychotics raise the hormone prolactin, which can disrupt periods, cause unwanted milk production, and affect sex drive. Most cases are manageable once recognised.
Side effectsExtrapyramidal symptoms are the family of movement side effects produced by dopamine-blocking medications. Understanding the four sub-types — and how they overlap — changes how they get treated.
