How long does it take for this medicine to take effect?

The onset of therapeutic effects of clozapine can vary significantly among individuals. Some patients may begin to notice improvements in their symptoms within the first few weeks of treatment, but full therapeutic benefits may take several months to develop. The initial effects often include sedation and a reduction in agitation.

How long do the effects of this medicine last?

Clozapine's effects are sustained with continuous use. The medication is typically prescribed for long-term management of schizophrenia symptoms, and consistent daily dosing is necessary to maintain its therapeutic benefits. The half-life of clozapine is about 12 to 16 hours, requiring twice-daily dosing to maintain steady blood levels.

Is it safe to consume alcohol while taking this medicine?

Consuming alcohol while taking clozapine is not recommended. Alcohol can exacerbate clozapine's central nervous system depressant effects, increasing the risk of sedation, dizziness, and impairing cognitive and motor skills. Additionally, alcohol use can worsen the side effects of clozapine, including seizures and orthostatic hypotension (a drop in blood pressure upon standing).

Is this a habit forming medicine?

Clozapine is not considered habit-forming and does not have a high potential for abuse or dependence. However, it is critical for patients to use this medication under strict medical supervision due to its risk profile, including the potential for severe side effects.

Can this medicine be taken during pregnancy?

Clozapine is classified as FDA Pregnancy Category B, indicating that animal reproduction studies have not demonstrated a risk to the fetus, but there are no adequate and well-controlled studies in pregnant women. Clozapine should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus, and it should be prescribed with caution after careful consideration of the risks and benefits.

Can this medicine be taken while breast-feeding?

Clozapine is excreted into breast milk, and there is potential for adverse effects on the nursing infant. Given the risk of serious side effects, including sedation and potential hematological abnormalities, breastfeeding is not recommended while taking clozapine. The decision to continue or discontinue either clozapine or breastfeeding should be made in consultation with a healthcare provider, considering the importance of the medication to the mother's health.

Uses

This medication is used to treat certain mental/mood disorders (schizophrenia, schizoaffective disorders). Clozapine is a psychiatric medication (anti-psychotic type) that works by helping to restore the balance of certain natural substances (neurotransmitters) in the brain.Clozapine decreases hallucinations and helps prevent suicide in people who are likely to try to harm themselves. It helps you to think more clearly and positively about yourself, feel less nervous, and take part in everyday life.

It is important to begin taking this drug at a low dose, increasing your dose slowly, to lessen side effects such as dizziness, drowsiness and seizures. Follow your doctor's instructions exactly. Your dosage is based on your medical condition and response to therapy. Since clozapine can cause a decrease in white blood cells, you will need to get blood tests done regularly as directed.

This medication can cause a serious decrease of a certain type of white blood cells (neutropenia). To make sure you have enough white blood cells, your doctor will order lab tests before starting and while your are taking clozapine. Neutropenia may lower your ability to fight infections. Get medical help right away if you have any signs of severe neutropenia or infection (such as sore throat that doesn't go away, fever, swollen lymph nodes, unusual tiredness, weakness).

Clozapine can also cause seizures, especially in higher doses. Let your doctor or pharmacist know if you have ever had seizures. While taking this medication, avoid driving or other activities during which a sudden loss of consciousness could be dangerous (such as operating heavy machinery, swimming).

This medication may rarely cause an inflammation of the heart muscle (myocarditis) or heart failure. Get medical help right away if you develop chest pain, fast/irregular heartbeat, shortness of breath, swelling ankles/feet, unusual tiredness, or unusual/sudden weight gain.

The risk is higher when you first start or increase your dose of medication. Dizziness and lightheadedness can increase the risk of falling. Get up slowly when rising from a sitting or lying position.

There may be a slightly increased risk of serious, possibly fatal side effects (such as stroke, heart failure, fast/irregular heartbeat, pneumonia) when this medication is used by older adults with dementia. This medication is not approved for the treatment of dementia-related behavior problems. Discuss the risks and benefits of this medication, as well as other effective and possibly safer treatments for dementia-related behavior problems, with the doctor.

Interactions

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions.

A product that may interact with this drug is: metoclopramide.

Other medications can affect the removal of clozapine from your body, which may affect how clozapine works. Examples include fluvoxamine, saquinavir, St. John's wort, drugs used to treat seizures (such as carbamazepine, phenytoin), among others.

Tell your doctor or pharmacist if you are taking other products that cause drowsiness such as opioid pain or cough relievers (such as codeine, hydrocodone), alcohol, marijuana (cannabis), drugs for sleep or anxiety (such as alprazolam, lorazepam, zolpidem), muscle relaxants (such as carisoprodol, cyclobenzaprine), or antihistamines (such as cetirizine, diphenhydramine).

Check the labels on all your medicines (such as allergy or cough-and-cold products) because they may contain ingredients that cause drowsiness. Ask your pharmacist about using those products safely.

Clozapine may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.

The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may affect the heart rhythm. Before using clozapine, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).

Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/”water pills”) or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using clozapine safely.

This drug may make you dizzy or drowsy or blur your vision. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness or clear vision until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).
