Janssen: Exclusively Dedicated to Mental Health

Our History Janssen is focused solely on mental health and helps patients achieve healthy minds and mental wellness. Janssen is a U.S. pharmaceutical company of the Johnson & Johnson Family of Companies. We represent part of the former Janssen Pharmaceutica, founded in 1953 by Dr. Paul Janssen - a prominent researcher, pharmacologist and physician. In 1958, Dr. Paul led a group of researchers who discovered HALDOL® (haloperidol), which would help change the way mental health patients were treated. Realizing that he needed the strength of a larger, multi-national company to continue this work, Dr. Paul and Janssen Pharmaceutica joined the Johnson & Johnson family of companies in 1961. Hallmarks of the Janssen scientific grounding and search for innovation remain. Today, the company is more focused than ever and is committed to pioneering solutions for healthy minds with the lean, entrepreneurial approach key to our predecessor's rich history of success. Janssen employs more than a thousand individuals throughout the United States. The company is headquartered in Titusville, NJ. Everyone at Janssen - extending from the highest level of management throughout the organization - is expected to model their work lives to the Credo.
Janssen has always been driven by dedication to product innovation, customer focus, and organizational excellence in combination with a firm grounding in science and the search for innovation. Over the decades, Janssen evolved into a company that produced and marketed many first-in-class prescription medications in multiple therapeutic categories including central nervous system disorders, gastrointestinal health, pain management, and fungal infections. Now, Janssen is exclusively focused on mental health - enabling us to build on our rich heritage with products such as HALDOL® (haloperidol), RISPERDAL® (risperidone) and other innovative advances such as the delivery system of RISPERDAL® CONSTA® (risperidone), the first long-acting atypical antipsychotic injectable product, and INVEGA® (paliperidone), the first oral atypical antipsychotic that uses OROS® extended-release technology. With Johnson & Johnson Pharmaceutical Research & Development, L.L.C., (J&JPRD), we're researching and developing new compounds for a wide range of psychiatric disorders, including psychosis, sleep, attention deficit/hyperactivity, anxiety, depression, and substance abuse. Because we know that with mental illness successful treatment involves more than just medication, we've strengthened our partnerships with advocacy and increased our investment in a broad array of unique resources, tools, and services. Today at Janssen, our priority is to provide innovative treatments and support to patients living with mental illness and to the people who care for them.
Dr. Paul's Legacy Dr. Paul Janssen was a leading Belgian researcher, pharmacologist and general practitioner. Dr. Paul, as he was widely known, was born and raised in Turnhout, Belgium. In fact, the Janssen logo is partly derived from the seal for the town of Turnhout, which is known for its deer-hunting grounds. Dr. Paul received his M.D. from the University of Ghent, where he worked with Corneille Heymans, the 1938 Nobel laureate in medicine. Later, he received his postdoctoral degree in pharmacology from the same university.
		Dr. Paul was known for sharing his passion for research through wise sayings and witticisms, and many of his favorites are widely remembered and quoted today. He once defined research as "the things one does to satisfy one's curiosity," and he was fond of constantly challenging his staff by asking, "What's new?" Realizing that he needed the strength of a larger, multi-national company to continue this work, Dr. Paul and Janssen Pharmaceutica joined the Johnson & Johnson Family of Companies in 1961. A U.S. office opened in 1973, based in the Johnson & Johnson headquarters in New Brunswick, NJ. Later, Janssen moved to two leased buildings in Piscataway, NJ, where it stayed until 1992. Janssen's current home is on 270 acres in Titusville, New Jersey.
Although Janssen has changed and grown beyond the days of Dr. Paul, his vision for the future still applies as we enter the 21st century: "There are still many diseases for which there is no cure, and effective drugs must be found. Although we have contributed to the solutions for some of these problems, we will continue our research efforts, because so much more needs to be done." Back to Top

INVEGA^® SUSTENNA™ (paliperidone palmitate) is used for the treatment of schizophrenia. IMPORTANT SAFETY INFORMATION FOR INVEGA^® SUSTENNA™ INVEGA® SUSTENNA™ is not approved for the treatment of dementia-related psychosis in elderly patients. Elderly patients who were given oral antipsychotics like INVEGA® SUSTENNA™ in clinical studies for psychosis caused by dementia (memory problems) had a higher risk of death. Neuroleptic Malignant Syndrome (NMS) is a rare, but serious side effect that could be fatal and has been reported with INVEGA® SUSTENNA™ and similar medicines. Call the doctor right away if you develop symptoms such as a high fever, rigid muscles, shaking, confusion, sweating more than usual, increased heart rate or blood pressure, or muscle pain or weakness. Treatment should be stopped if you are being treated for NMS. Tardive Dyskinesia (TD) is a rare, but serious and sometimes permanent side effect reported with INVEGA® SUSTENNA™ and similar medicines. Call your doctor right away if you start to develop twitching or jerking movements that you cannot control in your face, tongue, or other parts of your body. The risk of developing TD and the chance that it will become permanent is thought to increase with the length of therapy and the total dose received. This condition can also develop after a short period of treatment at low doses but this is less common. There is no known treatment for TD but it may go away partially or completely if the medicine is stopped. One risk of INVEGA® SUSTENNA™ is that it may change your heart rhythm. This effect is potentially serious. You should talk to your doctor about any current or past heart problems. Because these problems could mean you're having a heart rhythm abnormality, contact your doctor IMMEDIATELY if you feel faint or feel a change in the way that your heart beats (palpitations). High blood sugar and diabetes have been reported with INVEGA® SUSTENNA™ and similar medicines. If you already have diabetes or have risk factors such as being overweight or a family history of diabetes, blood sugar testing should be done at the beginning and during the treatment. The complications of diabetes can be serious and even life-threatening. Call your doctor if you develop signs of high blood sugar or diabetes, such as being thirsty all the time, having to urinate or "pass urine" more often than usual, or feeling weak or hungry. Weight gain has been observed with INVEGA® SUSTENNA™ and other atypical antipsychotic medications. If you notice that you are gaining weight, please notify your doctor. Some people may feel faint, dizzy, or may pass out when they stand up or sit up suddenly. Be careful not to get up too quickly. It may help if you get up slowly and sit on the edge of the bed or chair for a few minutes before you stand up. These symptoms may decrease or go away after your body becomes used to the medicine. INVEGA® SUSTENNA™ and similar medicines have been associated with decreases in the counts of white cells in circulating blood. If you have a history of low white blood cell counts or have unexplained fever or infection, then please contact your doctor right away. INVEGA® SUSTENNA™ and similar medicines can raise the blood levels of a hormone called prolactin and blood levels of prolactin remain high with continued use. This may result in some side effects including missed menstrual periods, leakage of milk from the breasts, development of breasts in men, or problems with erection. If you have a prolonged or painful erection lasting more than 4 hours, seek immediate medical help to avoid long-term injury. Call your doctor right away if you start thinking about suicide or wanting to hurt yourself. INVEGA® SUSTENNA™ can make some people feel dizzy, sleepy, or less alert. Until you know how you are going to respond to INVEGA® SUSTENNA™, be careful driving a car, operating machines, or doing things that require you to be alert. This medicine may make you more sensitive to heat. You may have trouble cooling off or be more likely to become dehydrated. Be careful when you exercise or spend time doing things that make you warm. Some medications interact with INVEGA® SUSTENNA™ Please inform your healthcare professional of any medications or supplements that you are taking. INVEGA® SUSTENNA™ should be used cautiously in people with a seizure disorder, who have had seizures in the past, or who have conditions that increase their risk for seizures. Inform your healthcare professional if you become pregnant or intend to become pregnant during therapy with INVEGA® SUSTENNA™. Do not drink alcohol while you are taking INVEGA® SUSTENNA™. In a study of people taking INVEGA® SUSTENNA™, common side effects in the treatment of schizophrenia were reactions at the injection site, sleepiness, dizziness, feeling of inner restlessness, and abnormal muscle movements, including tremor (shaking), shuffling, uncontrolled involuntary movements, and abnormal movements of the eyes. This is not a complete list of all possible side effects. Ask your doctor or treatment team if you have any questions or want more information. If you have any questions about INVEGA® SUSTENNA™ or your therapy, talk with your doctor. Back to Top RISPERDAL® CONSTA® (risperidone) is used for the treatment of schizophrenia and for the longer-term treatment of Bipolar I Disorder. IMPORTANT SAFETY INFORMATION FOR RISPERDAL® CONSTA® Elderly Patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death compared to placebo. RISPERDAL® CONSTA® (risperidone) is not approved for the treatment of patients with dementia-related psychosis. Neuroleptic Malignant Syndrome (NMS) is a rare and potentially fatal side effect reported with RISPERDAL® CONSTA® and similar medicines. Call your doctor immediately if the person being treated develops symptoms such as high fever; stiff muscles; shaking; confusion; sweating; changes in pulse, heart rate, or blood pressure; or muscle pain and weakness. Treatment should be stopped if the person being treated has NMS. Tardive Dyskinesia (TD) is a serious, sometimes permanent side effect reported with RISPERDAL® CONSTA® and similar medications. TD includes uncontrollable movements of the face, tongue, and other parts of the body. The risk of developing TD and the chance that it will become permanent is thought to increase with the length of therapy and the overall dose taken by the patient. This condition can develop after a brief period of therapy at low doses, although this is much less common. There is no known treatment for TD, but it may go away partially or completely if therapy is stopped. High blood sugar and diabetes have been reported with RISPERDAL® CONSTA® and similar medications. If the person being treated has diabetes or risk factors such as being overweight or a family history of diabetes, blood sugar testing should be performed at the beginning and throughout treatment with RISPERDAL® CONSTA®. Complications of diabetes can be serious and even life threatening. If signs of high blood sugar or diabetes develop, such as being thirsty all the time, going to the bathroom a lot, or feeling weak or hungry, contact your doctor. RISPERDAL® CONSTA® and similar medications can raise the blood levels of a hormone known as prolactin, causing a condition known as hyperprolactinemia. Blood levels of prolactin remain elevated with continued use. Some side effects seen with these medications include the absence of a menstrual period; breasts producing milk; the development of breasts by males; and the inability to achieve an erection. Some people taking RISPERDAL® CONSTA® may feel faint or lightheaded when they stand up or sit up too quickly. By standing up or sitting up slowly and following your healthcare professional's dosing instructions, this side effect can be reduced or it may go away over time. Blood problems such as low numbers of white blood cells have been reported in patients taking risperidone and similar medications. In some cases it has been serious and life-threatening. Depending upon your medical condition, your doctor may choose to test your blood as you start therapy with RISPERDAL® CONSTA®. RISPERDAL® CONSTA® may affect your alertness or driving ability; therefore, do not drive or operate machinery before talking to your healthcare professional. RISPERDAL® CONSTA® should be used cautiously in people with a seizure disorder, who have had seizures in the past, or who have conditions that increase their risk for seizures. Painful, long lasting erections have been reported with the use of RISPERDAL® CONSTA®. Call your doctor immediately if you think you are having this problem. Extrapyramidal Symptoms (EPS) are usually persistent movement disorders or muscle disturbances, such as restlessness, tremors, and muscle stiffness. If you observe any of these symptoms, talk to your healthcare professional. Inform your healthcare professional if you become pregnant or intend to become pregnant during therapy with RISPERDAL® CONSTA®. Caution should be exercised when administering RISPERDAL® CONSTA® to a nursing woman. RISPERDAL® CONSTA® may make you more sensitive to heat. You may have trouble cooling off, or be more likely to become dehydrated, so take care when exercising or when doing things that make you warm. Some medications interact with RISPERDAL® CONSTA®. Please inform your healthcare professional of any medications or supplements that you are taking. Avoid alcohol while on RISPERDAL® CONSTA®. In a study of people taking RISPERDAL® CONSTA®, the most common side effects in the treatment of schizophrenia were headache, tremors, dizziness, restlessness, tiredness, constipation, indigestion, sleepiness, weight gain, pain in the limbs, and dry mouth. In a study of people taking RISPERDAL® CONSTA®, the most common side effects in the treatment of bipolar disorder were weight gain (when used alone) and tremors (when used with lithium or valproate). If you have any questions about RISPERDAL® CONSTA® or your therapy, talk with your doctor. 01CS09130 Back to Top INVEGA® (paliperidone) extended-release tablets are used for the treatment of schizophrenia. RISPERDAL® (risperidone) is used for the treatment of irritability associated with autistic disorder; the treatment of schizophrenia; and the treatment of acute manic or mixed episodes associated with Bipolar I Disorder.
