Loxapine: the inhaled and oral antipsychotic

Loxapine is one of the few antipsychotics that exists as both a daily oral tablet and an inhaled rescue medication for acute agitation. Here is how it works and where it fits.

Ziprasidone side effects: QT, food requirements, akathisia

Ziprasidone is one of the most weight-friendly antipsychotics — but it requires food with every dose, modest QT monitoring, and patience with akathisia.

Paliperidone (Invega): risperidone's active metabolite, on its own

Paliperidone is the active metabolite of risperidone, sold as a once-daily extended-release pill and as long-acting injections lasting from a month to six months.

Fertility on antipsychotics: prolactin and beyond

Antipsychotics can affect fertility — most often through prolactin. Most fertility issues are reversible with the right medication adjustment and time.

Olanzapine pamoate (Zyprexa Relprevv) and post-injection syndrome

Zyprexa Relprevv is the long-acting injectable form of olanzapine — and the only LAI that requires three hours of in-clinic observation after every injection. Here's why.

Quetiapine vs olanzapine: sedation, weight, and when each is chosen

Quetiapine and olanzapine are two of the most-prescribed atypicals — both sedating, both metabolically heavy, but with different efficacy and very different roles in practice.

SSRIs and antipsychotics: common combinations, common pitfalls

Combining SSRIs with antipsychotics is one of the most common decisions in modern schizophrenia care. The decision is rarely binary — it's about which SSRI, at what dose, with what monitoring.

CBD (cannabidiol) for schizophrenia: what the evidence shows

CBD is the non-intoxicating component of cannabis. Small trials suggest possible antipsychotic activity, but the evidence is far from conclusive and it is not a replacement for established treatment.

Fluphenazine (Prolixin): high-potency typical with an LAI option

Fluphenazine is a high-potency typical antipsychotic with both oral tablets and a long-acting injection — a combination that made it a workhorse of community psychiatry for decades.

Lurasidone (Latuda): the metabolically friendly atypical

Lurasidone is among the most metabolically friendly atypicals — particularly useful in bipolar depression — but absorption depends on a meal of at least 350 calories.

Antipsychotic stewardship: 'right drug, right dose, right duration'

Stewardship is borrowed from antibiotics — but the idea applies to antipsychotics too. Right drug, right dose, right duration, right monitoring, with regular reconsideration.

TSH/thyroid monitoring on antipsychotics and lithium

Lithium changes thyroid function in a meaningful subset of patients. Some antipsychotics also have small effects. Routine TSH catches the changes long before they cause symptoms.

Lurasidone vs ziprasidone: the metabolically friendly atypicals

Lurasidone and ziprasidone are the two atypicals most often chosen when weight and metabolic burden need to stay low — but each has its own quirks worth understanding.

Molindone: the antipsychotic that doesn't cause weight gain

Most antipsychotics cause weight gain. Molindone is an exception — and that simple fact has kept the drug part of the conversation despite limited current availability.

Benzodiazepines in acute psychosis: short-term tool, long-term risk

Benzodiazepines have a legitimate short-term role in psychotic emergencies, catatonia, and severe insomnia. They become dangerous when they are not stopped.

Brexpiprazole (Rexulti): the gentler partial agonist

Brexpiprazole is aripiprazole's structural cousin — also a partial dopamine agonist, but designed to cause less akathisia and activation.

Antipsychotics and oral contraceptives

Oral contraceptives and antipsychotics generally combine safely, but there are some specific situations — enzyme-inducing drugs, prolactin elevation, and the menstrual cycle's effect on symptoms — where attention is needed.

Contraception and antipsychotics: drug interactions

Most contraceptive methods are compatible with most antipsychotics. The few interactions that matter are worth knowing about — for both effectiveness and side effects.

NSAIDs and clozapine: lithium-like and other concerns

Ibuprofen, naproxen, and similar NSAIDs are among the most-used over-the-counter drugs. With clozapine they raise concerns about renal function, bleeding, and rare interactions worth understanding.

Clozapine augmentation strategies for partial responders

Roughly 40–70% of people on clozapine are partial responders — better than before, but still symptomatic. Here's what the evidence supports as augmentation, and what to skip.

Atypical vs typical antipsychotics: what 60 years of evidence shows

The difference between first- and second-generation antipsychotics is real, but smaller than 1990s marketing suggested. The CATIE and CUtLASS trials reshaped how psychiatrists think about both classes.

Perphenazine (Trilafon): the mid-potency typical that held its own in CATIE

Perphenazine, an older mid-potency typical, surprised the field in the 2005 CATIE trial by matching newer atypicals on most outcomes. It remains a quietly useful option.

Flupentixol (Fluanxol) — outside the US

Flupentixol is a thioxanthene antipsychotic widely used outside the US, with both oral and depot forms — and a low-dose indication for depression that does not exist for most other antipsychotics.

Uzedy (risperidone subcutaneous LAI): once-monthly or every 2 months

Uzedy is a newer subcutaneous risperidone LAI that offers once-monthly or every-two-month dosing, no loading dose, and no required oral overlap. Here's how it compares.

Pimozide: the antipsychotic for delusional disorder

Pimozide has a narrow but distinctive role: FDA-approved for Tourette syndrome, long associated off-label with delusional disorder, and demanding careful cardiac monitoring.

Paliperidone side effects: prolactin, EPS, what to watch for

Paliperidone shares much of risperidone's profile — including prolactin elevation and movement effects — but has its own dosing logic that shapes the experience.

Cariprazine (Vraylar): the D3-preferring partial agonist

Cariprazine is a partial dopamine agonist that prefers the D3 receptor, with growing evidence in negative symptoms of schizophrenia and bipolar depression.

Long-acting injectable vs oral antipsychotics: trade-offs

Long-acting injectables remove the daily question of whether to take the pill. They consistently lower relapse rates — but they also constrain dose adjustment and demand a different kind of trust.

Lamotrigine (Lamictal) in schizophrenia and schizoaffective disorder

Lamotrigine has a niche but defensible role as augmentation in clozapine-resistant schizophrenia and as a mood stabiliser in schizoaffective disorder, depressive type. The rash risk demands respect.

LFT (AST/ALT) monitoring on antipsychotics

Most antipsychotics cause occasional, mild liver enzyme changes that resolve on their own. Knowing when to check, when to worry, and when to act keeps the picture clear.
