    CLOZAPINE - ORAL

    (KLOE-za-peen)

    COMMON BRAND NAME(S): Clozaril

    WARNING: While clozapine can provide great benefits, it can rarely cause serious, possibly fatal side effects. For this reason, clozapine is used when other treatments have not worked or you cannot take them. This medication can cause a serious immune system problem called agranulocytosis (low white blood cells). To make sure you have enough white blood cells, you will need to have a blood test before you begin taking clozapine and then have your blood tested regularly during your treatment. (See also How to Use, Side Effects, and Notes sections.) 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 (e.g., operating heavy machinery, swimming). This medication may rarely cause an inflammation of the heart muscle (myocarditis). Seek immediate medical attention if you have weakness, difficult/rapid breathing, chest pain, or swelling of the ankles/legs. Your risk is highest in the first month of treatment. Clozapine can cause a big drop in blood pressure, which can make you dizzy or cause you to faint when you stand up. Be sure to get up slowly while taking this medication. This is more likely to occur when your dose of clozapine is increased or if you are also taking a benzodiazepine (e.g., clonazepam, lorazepam, diazepam). There may be a slightly increased risk of serious, possibly fatal side effects (e.g., stroke, heart failure) when this medication is used in elderly patients with dementia. Discuss the risks and benefits of this medication, as well as other effective and possibly safer treatments for dementia-related behavior problems, with your doctor.

    USES: See also Warning section. 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.

    HOW TO USE: Take this medication by mouth with or without food, as directed by your doctor. If you are taking the tablets that dissolve in the mouth, carefully remove each tablet from the blister pack immediately before taking your dose. Allow the tablets to dissolve on your tongue and swallow. You do not need to take the dissolving tablets with water. Discard any dissolving tablets that have been previously exposed to air due to opened/damaged packaging. Do not save them for your next dose. 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. Be sure to keep all appointments for these laboratory tests. If you miss your doses for longer than a day or two, consult your doctor for a new schedule to get back to the dose you were on (see Missed Dose section). Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time(s) each day. Do not stop taking clozapine without consulting your doctor. Some conditions may become worse when the drug is suddenly stopped. Your dose may need to be gradually decreased if the doctor decides that you should stop taking this medication. It may take several weeks before the full benefit of this drug takes effect. Inform your doctor if your condition persists or worsens.

    SIDE EFFECTS: Drooling, drowsiness, dizziness, headache, shaking (tremor), vision problems (e.g., blurred vision), weight gain, and constipation may occur. Many of these effects (especially drowsiness) lessen as your body gets used to the medication. If any of these effects persist or worsen, contact your doctor or pharmacist promptly. To prevent constipation, maintain a diet adequate in fiber, drink plenty of water, and exercise. If you become constipated while using this drug, consult your pharmacist for help in selecting a laxative (e.g., stimulant-type with stool softener). Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Tell your doctor immediately if any of these unlikely but serious side effects occur: facial/muscle twitching, signs of infection (e.g., severe tiredness, fever, persistent sore throat), seizures, uncontrollable movements, change in the amount of urine. Seek immediate medical attention if any of these rare but very serious side effects occur: high fever, fast/irregular heartbeat, severe dizziness, fainting, muscle stiffness, mental/mood changes, difficulty breathing with exercise, swollen legs/feet, sudden weakness, pain/redness/swelling of the arms/legs, chest pain, dark urine, persistent nausea/vomiting, stomach/abdominal pain, yellowing of eyes/skin. A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction may include: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing. This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist. In the US - Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088. In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.

    PRECAUTIONS: See also Warning section. Before taking clozapine, tell your doctor or pharmacist if you are allergic to it or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details. This medication should not be used if you have certain medical conditions. Before using this medicine, consult your doctor or pharmacist if you have: history of blood disorders (e.g., leukemia, low white blood cell count), history of blood disorders caused by clozapine, serious bowel problems (e.g., paralytic ileus), seizures not controlled by medication. Before using this medication, tell your doctor or pharmacist your medical history, especially of: bowel problems (e.g., irritable bowel syndrome), breathing problems, diabetes/family history of diabetes, glaucoma, heart problems, kidney problems, liver problems, obesity/family history of obesity, seizures, difficulty urinating (e.g., prostate problems). Clozapine may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can infrequently result in 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 cause blurred vision. Do not drive, use machinery, or do any activity that requires alertness or clear vision until you are sure you can perform such activities safely. Limit alcoholic beverages. To minimize dizziness and lightheadedness, get up slowly when rising from a seated or lying position. Tell your doctor if you are a descendent of Ashkenazi Jews because you may be at a higher risk for a drop in your white blood cells. Before having surgery, tell your doctor or dentist that you are using this medication. The rapidly dissolving form of this drug may contain aspartame or phenylalanine. If you have phenylketonuria (PKU) or any other condition that requires you to restrict your intake of aspartame (or phenylalanine), consult your doctor or pharmacist about the safe use of this medicine. This drug may infrequently make your blood sugar level rise, causing or worsening diabetes. This high blood sugar can rarely cause serious conditions such as diabetic coma. Tell your doctor immediately if you develop symptoms of high blood sugar, such as increased thirst or urination. If you already have diabetes, be sure to check your blood sugar regularly. This drug may also cause significant weight gain. These effects, along with diabetes, may increase your risk for developing heart disease. Discuss the risks and benefits of treatment with your doctor. The elderly may be more sensitive to the effects of this drug, especially side effects such as constipation and low blood pressure. During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor. Do not stop taking this medication unless directed by your doctor. Babies born to mothers who have used this drug during the last 3 months of pregnancy may infrequently develop symptoms including muscle stiffness or shakiness, drowsiness, feeding/breathing difficulties, or constant crying. If you notice any of these symptoms in your newborn anytime during their first month, tell the doctor right away. This medication may pass into breast milk and have undesirable effects on a nursing infant. Breast feeding is not recommended while taking clozapine. Consult your doctor before breast-feeding.

    DRUG INTERACTIONS: Your healthcare professionals (e.g., doctor or pharmacist) may already be aware of any possible drug interactions and may be monitoring you for it. Do not start, stop or change the dosage of any medicine before checking with them first. This drug should not be used with the following medication because a very serious interaction may occur: sibutramine. If you are currently using the medication listed above, tell your doctor or pharmacist before starting clozapine. Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of: antispasmodic or drying medications (e.g., anticholinergics such as belladonna alkaloids), benzodiazepines (e.g., lorazepam, clonazepam, diazepam), carbamazepine, certain antidepressants (e.g., citalopram, SSRIs-especially fluvoxamine), lithium, medications for high blood pressure (e.g., beta blockers such as propranolol, water pills such as furosemide, ACE inhibitors such as lisinopril), drugs affecting liver enzymes that remove clozapine from the body (such as azole antifungals including itraconazole, macrolide antibiotics including erythromycin, tobacco and other nicotine-containing products, cimetidine, rifampin, certain anti-seizure medicines including phenytoin, antiarrhythmics such as propafenone/flecainide/quinidine). Tell your doctor or pharmacist about any medications or treatment that may decrease your blood cell count such as chemotherapy, radiation therapy, or medications for autoimmune disorders such as rheumatoid arthritis (e.g., methotrexate, azathioprine). Also report the use of drugs which might increase seizure risk (decrease seizure threshold) when combined with clozapine such as isoniazid (INH), phenothiazines (e.g., thioridazine), theophylline, or tricyclic antidepressants (e.g., amitriptyline), among others. Consult your doctor or pharmacist for details. Tell your doctor or pharmacist if you also take drugs that cause drowsiness such as certain antihistamines (e.g., diphenhydramine), anti-seizure drugs (e.g., valproate), medicines for sleep or anxiety (e.g., alprazolam, zolpidem), muscle relaxants, narcotic pain relievers (e.g., codeine), psychiatric medicines (e.g., chlorpromazine, risperidone, trazodone). Check the labels on all your medicines (e.g., cough-and-cold products) because they may contain drowsiness-causing ingredients. Ask your pharmacist about the safe use of those products. This document does not contain all possible interactions. Therefore, before using this product, tell your doctor or pharmacist of all the products you use. Keep a list of all your medications with you, and share the list with your doctor and pharmacist.

    OVERDOSE: If overdose is suspected, contact your local poison control center or emergency room immediately. US residents can call the US national poison hotline at 1-800-222-1222. Canadian residents should call their local poison control center directly.

    NOTES: Do not share this medication with others. Laboratory tests (e.g., blood tests) should be performed weekly for the first 6 months of treatment. During the next 6 months, they should be performed at least every 2 weeks. After that, they should be performed regularly no less often than once a month while you are on clozapine and for at least 4 weeks after you stop taking it. Your testing schedule may be changed if you develop a low white blood cell count, or if your treatment is interrupted. Your doctor may also order other laboratory and/or medical tests (e.g., liver function, blood sugar, weight) from time to time. Consult your doctor for more details.

    MISSED DOSE: If you miss a dose, take it as soon as you remember. If it is near the time of the next dose, skip the missed dose and resume your usual dosing schedule. If you miss doses for longer than a day or two, consult your doctor for a new schedule to get back to the dose you were taking. Do not double the dose to catch up.

    STORAGE: Store at room temperature no higher than 86 degrees F (30 degrees C) away from light and moisture. Store the dissolving tablets at 77 degrees F (25 degrees C) in their blister packets, and do not remove each dose until immediately before taking. Brief storage between 59-86 degrees F (15-30 degrees C) is permitted. Do not store in the bathroom. Keep all medicines away from children and pets. Do not flush medications down the toilet or pour them into a drain unless instructed to do so. Properly discard this product when it is expired or no longer needed.
