Medicare Part D
Overview of Medicare
Medicare is a federal program that provides health insurance coverage to the following types of people:
- Individuals over age 65 with a work history
- Individuals with certain disabilities who have been disabled for at least 2 years
- Individuals diagnosed with end-stage renal disease (ESRD)
While Medicare covers many healthcare needs, it may not cover all of the patient's healthcare costs. The patient may have to pay a monthly premium for Medicare and then pay a co-insurance and a deductible for many services.
Our Medicare Resource Guide provides important information for your patients to consider as they are selecting their insurance coverage.
INVEGA TRINZA® (paliperidone palmitate) a 3‑month injection, is an atypical antipsychotic indicated for the treatment of schizophrenia in patients after they have been adequately treated with INVEGA SUSTENNA® (1‑month paliperidone palmitate) for at least four months.
INVEGA SUSTENNA® (paliperidone palmitate) is an atypical antipsychotic indicated for the treatment of schizophrenia in adults.
WARNING: INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA‑RELATED PSYCHOSIS.
See full Prescribing Information for complete Boxed Warning
Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. INVEGA SUSTENNA® and INVEGA TRINZA® are not approved for use in patients with dementia-related psychosis.
Contraindications: INVEGA TRINZA® and INVEGA SUSTENNA® are contraindicated in patients with a known hypersensitivity to either paliperidone, risperidone, or to any excipients of their formulation.
Cerebrovascular Adverse Reactions: Cerebrovascular adverse reactions (e.g., stroke, transient ischemic attacks), including fatalities, were reported at a higher incidence in elderly patients with dementia-related psychosis taking risperidone, aripiprazole, and olanzapine compared to placebo. No studies have been conducted with oral paliperidone, INVEGA SUSTENNA®, or INVEGA TRINZA® in elderly patients with dementia. These medications are not approved for the treatment of patients with dementia-related psychosis.
Neuroleptic Malignant Syndrome (NMS): NMS, a potentially fatal symptom complex, has been reported with the use of antipsychotic medications, including paliperidone. Clinical manifestations include muscle rigidity, fever, altered mental status, and evidence of autonomic instability (see full Prescribing Information). Management should include immediate discontinuation of antipsychotic drugs and other drugs not essential to concurrent therapy, intensive symptomatic treatment and close medical monitoring, and treatment of any concomitant serious medical problems.
QT Prolongation: Paliperidone causes a modest increase in the corrected QT (QTc) interval. Avoid the use of drugs that also increase QTc interval and in patients with risk factors for prolonged QTc interval. Paliperidone should also be avoided in patients with congenital long QT syndrome and in patients with a history of cardiac arrhythmias. Certain circumstances may increase the risk of the occurrence of torsades de pointes and/or sudden death in association with the use of drugs that prolong the QTc interval.
Tardive Dyskinesia (TD): TD is a syndrome of potentially irreversible, involuntary, dyskinetic movements that may develop in patients treated with antipsychotic medications. The risk of developing TD and the likelihood that dyskinetic movements will become irreversible are believed to increase with duration of treatment and total cumulative dose, but can develop after relatively brief treatment at low doses. Elderly female patients appeared to be at increased risk for TD, although it is impossible to predict which patients will develop the syndrome. Prescribing should be consistent with the need to minimize the risk of TD (see full Prescribing Information). Discontinue drug if clinically appropriate. The syndrome may remit, partially or completely, if antipsychotic treatment is withdrawn.
Metabolic Changes: Atypical antipsychotic drugs have been associated with metabolic changes that may increase cardiovascular/cerebrovascular risk. These metabolic changes include hyperglycemia, dyslipidemia, and body weight gain. While all of the drugs in the class have been shown to produce some metabolic changes, each drug has its own specific risk profile.
Hyperglycemia and Diabetes Mellitus: Hyperglycemia and diabetes mellitus, in some cases extreme and associated with ketoacidosis, hyperosmolar coma or death, have been reported in patients treated with all atypical antipsychotics (APS). Patients starting treatment with APS who have or are at risk for diabetes mellitus should undergo fasting blood glucose testing at the beginning of and during treatment. Patients who develop symptoms of hyperglycemia during treatment should also undergo fasting blood glucose testing. All patients treated with atypical antipsychotics should be monitored for symptoms of hyperglycemia. Some patients require continuation of antidiabetic treatment despite discontinuation of the suspect drug.
Dyslipidemia: Undesirable alterations have been observed in patients treated with atypical antipsychotics.
Weight Gain: Weight gain has been observed with atypical antipsychotic use. Clinical monitoring of weight is recommended.
Orthostatic Hypotension and Syncope: INVEGA TRINZA® and INVEGA SUSTENNA® may induce orthostatic hypotension in some patients due to its alpha-adrenergic blocking activity. INVEGA TRINZA® and INVEGA SUSTENNA® should be used with caution in patients with known cardiovascular disease, cerebrovascular disease or conditions that would predispose patients to hypotension (e.g., dehydration, hypovolemia, treatment with antihypertensive medications). Monitoring should be considered in patients for whom this may be of concern.
Falls: Somnolence, postural hypotension, motor and sensory instability have been reported with the use of antipsychotics, including INVEGA TRINZA® and INVEGA SUSTENNA®, which may lead to falls and, consequently, fractures or other fall-related injuries. For patients, particularly the elderly, with diseases, conditions, or medications that could exacerbate these effects, assess the risk of falls when initiating antipsychotic treatment and recurrently for patients on long-term antipsychotic therapy.
Leukopenia, Neutropenia and Agranulocytosis have been reported with antipsychotics, including INVEGA TRINZA® and INVEGA SUSTENNA®. In patients with a history of clinically significant low white blood cell count (WBC)/absolute neutrophil count (ANC) or drug-induced leukopenia/neutropenia, perform a complete blood count frequently during the first few months of therapy. Consider discontinuing INVEGA TRINZA® and INVEGA SUSTENNA® at the first sign of a clinically significant decline in WBC in the absence of other causative factors. Monitor patients with clinically significant neutropenia for fever or other symptoms or signs of infection and treat promptly if such symptoms or signs occur. Discontinue INVEGA TRINZA® and INVEGA SUSTENNA® in patients with severe neutropenia (absolute neutrophil count <1000/mm3) and follow their WBC until recovery.
Hyperprolactinemia: As with other drugs that antagonize dopamine D2 receptors, INVEGA TRINZA® and INVEGA SUSTENNA® elevate prolactin levels, and the elevation persists during chronic administration. Paliperidone has a prolactin-elevating effect similar to risperidone, which is associated with higher levels of prolactin elevation than other antipsychotic agents.
Potential for Cognitive and Motor Impairment: Somnolence, sedation, and dizziness were reported as adverse reactions in subjects treated with INVEGA TRINZA® and INVEGA SUSTENNA®. INVEGA TRINZA® and INVEGA SUSTENNA® have the potential to impair judgment, thinking, or motor skills. Patients should be cautioned about performing activities that require mental alertness such as operating hazardous machinery, including motor vehicles, until they are reasonably certain that INVEGA TRINZA® and INVEGA SUSTENNA® do not adversely affect them.
Seizures: INVEGA TRINZA® and INVEGA SUSTENNA® should be used cautiously in patients with a history of seizures or with conditions that potentially lower seizure threshold. Conditions that lower seizure threshold may be more prevalent in patients 65 years or older.
Administration: For intramuscular injection only by a healthcare professional using only the needles provided in the INVEGA TRINZA® or INVEGA SUSTENNA® kits. Care should be taken to avoid inadvertent injection into a blood vessel.
Drug Interactions: Strong CYP3A4/P-glycoprotein (P-gp) inducers: Avoid using a strong inducer of CYP3A4 and/or P-gp (e.g., carbamazepine, rifampin, St John’s Wort) during a dosing interval for INVEGA TRINZA® or INVEGA SUSTENNA®. If administering a strong inducer is necessary, consider managing the patient using paliperidone extended-release tablets.
Pregnancy/Nursing: INVEGA TRINZA® and INVEGA SUSTENNA® may cause extrapyramidal and/or withdrawal symptoms in neonates with third trimester exposure. Advise patients to notify their healthcare professional if they become pregnant or intend to become pregnant during treatment with INVEGA TRINZA® or INVEGA SUSTENNA®. Patients should be advised that there is a pregnancy registry that monitors outcomes in women exposed to INVEGA TRINZA® or INVEGA SUSTENNA® during pregnancy. INVEGA TRINZA® and INVEGA SUSTENNA® can pass into human breast milk. The benefits of breastfeeding should be considered along with the mother’s clinical need for INVEGA TRINZA® or INVEGA SUSTENNA® and any potential adverse effect on the breastfed infant from INVEGA TRINZA® or INVEGA SUSTENNA® or the mother’s underlying condition.
Commonly Observed Adverse Reactions for INVEGA TRINZA®: The most common adverse reactions (incidence ≥ 5% and occurring at least twice as often as placebo) were injection site reaction, weight increased, headache, upper respiratory tract infection, akathisia and parkinsonism.
Commonly Observed Adverse Reactions for INVEGA SUSTENNA®: The most common adverse reactions in clinical trials in patients with schizophrenia (incidence ≥ 5% and occurring at least twice as often as placebo) were injection site reactions, somnolence/sedation, dizziness, akathisia and extrapyramidal disorder.
