Antipsychotic Medication: What You Need to Know
If you or someone you care about is starting an antipsychotic medication, you probably have a lot of questions. Antipsychotics treat symptoms like hallucinations, severe agitation, and mania, and can prevent relapse in conditions such as schizophrenia and bipolar disorder. They’re also used as add-ons for severe depression or behavior issues in some cases.
There are two broad groups: first-generation (typical) antipsychotics and second-generation (atypical) antipsychotics. Typical drugs are older and can cause movement-related side effects more often. Atypical antipsychotics generally have lower risk of those movement problems but carry higher risk of weight gain and metabolic issues for many people.
How they differ and when each is used
Some drugs work faster and are used in acute psychosis, others are better long-term. Clozapine is the most effective option for treatment-resistant schizophrenia, but it needs regular blood tests because of rare but serious risks. Long-acting injectables (LAIs) are great if daily pills are hard to keep up with — they come every 2–12 weeks depending on the medication.
Common side effects and how to manage them
Expect some side effects. Movement issues (akathisia, tremor, stiffness) can appear with some medications; ask your prescriber about dose changes or medicines like propranolol or anticholinergics if that happens. Weight gain, high blood sugar and lipid changes are common with many atypical drugs — track your weight, get fasting glucose and lipid labs at baseline and periodically, and prioritize diet and activity. Sedation can be managed by taking the med at night. Constipation is serious with drugs like clozapine; report it early.
Some antipsychotics raise prolactin, which can affect periods, sexual function, or cause breast changes. Heart issues such as QT prolongation are rare but worth checking if you have heart disease or take other QT-affecting meds. Many antipsychotics interact with CYP450 enzymes, so tell your clinician about all prescription, OTC, and herbal products you use.
Never stop an antipsychotic suddenly without medical advice — withdrawal can cause rebound symptoms or withdrawal effects. If switching is needed, your clinician will plan a gradual change or cross-taper to reduce risk.
Beyond medication, psychosocial supports matter a lot. Therapy, supported employment, sleep routines, and family education help medications work better. If side effects or lack of benefit are a problem, ask about dose adjustment, switching agents, or adding targeted treatments (for example, metformin for weight control in some cases).
If you have questions or notice worrying symptoms — extreme drowsiness, high fever, stiff muscles, breathing trouble, severe constipation, fast heartbeat, or confusion — get urgent medical help. For everyday concerns, work with your prescriber and pharmacist to find the safest, most effective plan for you.
