Examgoals

Studies involving risperidone suggest an increased risk of hyperglycemia-related adverse reactions as seen in people with diabetes. Although there is no clear link between risperidone and diabetes, patients should be tested during treatment for elevated blood sugars. Additionally, persons with risk factors for diabetes, including obesity or a family history of diabetes, should have their fasting levels of blood sugar tested before starting treatment and periodically throughout treatment to detect the onset of diabetes.

Dosage for acute manic or mixed bipolar I disorder episodes

Test risperidone tolerability by trial with oral risperidone before initiating injection therapy. Due to the delayed onset of action, the first injection should be overlapped with an oral antipsychotic drug at an effective dose for the first week (Rykindo) or the first 3 weeks (Risperdal Consta). The long-acting risperidone injection has received FDA approval as a treatment for schizophrenia and maintenance of bipolar disorder (as monotherapy or adjunctive to valproate or lithium) in adults. Many other medicines may alter the blood levels of risperidone. Tell your health care provider about all medicines that you take or have recently taken.

RISPERDAL M-TAB Orally Disintegrating Tablets 0.5 mg, 1 mg, and 2 mg are supplied in blister packs of 4 tablets each. Patients experiencing persistent somnolence may benefit from a once-daily dose administered at bedtime or administering half the daily dose twice daily, or a reduction of the dose. Although there are no data to specifically address reinitiation of treatment, it is recommended that after an interval off RISPERDAL, the initial titration schedule should be followed. Patients experiencing persistent somnolence may benefit from administering half the daily dose twice daily. There are other drugs available to treat your condition.

It can lower the response of your body to cold temperatures. If you have trouble controlling your body temperature, call your care team right away. Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use Risperdal only for the indication prescribed. Aristada (aripiprazole) is an antipsychotic medication.

Symptoms

The most common side effects of Uzedy are listed below. Tell your healthcare provider if you have any of these side effects that bother you. Uzedy belongs to a group of medicines called second-generation (atypical) antipsychotics.

• RISPERDAL (0.25 mg twice daily) did not show a clinically relevant effect on the pharmacokinetics of digoxin.
• If you miss an appointment to get your injectable risperidone dose, call to make another appointment as soon as possible.
• Psychiatry consultation is required if the overdose is intentional.
• The use of alcohol or other medicines that affect the CNS with risperidone may worsen the side effects of this medicine, such as dizziness, poor concentration, drowsiness, unusual dreams, and trouble with sleeping.
• This medication can cause problems with controlling your body temperature.

Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function see DOSAGE AND ADMINISTRATION. Tissue culture experiments indicate that approximately one-third of human breast cancers are prolactin dependent in vitro, a factor of potential importance if the prescription of these drugs is contemplated in a patient with previously detected breast cancer. An increase in pituitary gland, mammary gland, and pancreatic islet cell neoplasia (mammary adenocarcinomas, pituitary and pancreatic adenomas) was observed in the risperidone carcinogenicity studies conducted in mice and rats see Nonclinical Toxicology. Published epidemiologic studies have shown inconsistent results when exploring the potential association between hyperprolactinemia and breast cancer. Another important side effect which may also occur include extrapyramidal effects (sudden, often jerky, involuntary motions of the head, neck, arms, body, or eyes) also occur. Risperidone may cause a condition called orthostatic hypotension during the early phase of treatment (the first week or two).

The percentage of users suffering from these side effects is not known. Let your doctor know if you begin to suffer from any of these side effects so you can receive any necessary treatment. Elderly patients should be restricted to 25 mg every two weeks, but they may need to limit their usage to 25 mg every 3 weeks if the drug is not clearing properly. There are no adequate studies of Risperdal in pregnant women.

Fetal/neonatal adverse reactions

In a long-term, open-label extension study in adolescent patients with schizophrenia, weight increase was reported as a treatment-emergent adverse event in 14% of patients. In 103 adolescent patients with schizophrenia, a mean increase of 9.0 kg was observed after 8 months of RISPERDAL treatment. The majority of that increase was observed within the first 6 months.

Dosages of Risperidone

In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are receiving this medicine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive. This dose produced plasma AUC of risperidone plus paliperidone about half the exposure observed in humans at the MRHD. In clinical trials in 1885 children and adolescents, galactorrhea was reported in 0.8% of RISPERDAL-treated patients and gynecomastia was reported in 2.3% of RISPERDAL-treated patients. Advise patients to inform their healthcare providers if they are taking, or plan to take any prescription or over-the-counter drugs, as there is a potential for interactions see DRUG INTERACTIONS.

usual dosage range

Clinical monitoring of weight is recommended during treatment. Possible risk factors for leukopenia/neutropenia include pre-existing low white blood cell count (WBC) and history of drug-induced leukopenia/neutropenia. When treating pediatric patients with RISPERDAL for any indication, weight gain should be assessed against that expected with normal growth. Weight gain has been observed with atypical antipsychotic use. Tardive dyskinesia may remit, partially or completely, if antipsychotic treatment is discontinued.

• Do not share risperidone with other people, even if they have the same condition as you.
• The exact mechanism of action of Risperdal is unknown, but like other anti-psychotics, it affects the way the brain works by interfering with communication among the brain’s nerves.
• These doses are equivalent to approximately 0.2, 0.75, and 3 times (mice) and 0.4, 1.5, and 6 times (rats) the MRHD of 16 mg/day, based on mg/m² body surface area.
• Consequently, patients should be evaluated carefully for a history of drug abuse, and such patients should be observed closely for signs of RISPERDAL misuse or abuse (e.g., development of tolerance, increases in dose, drug-seeking behavior).
• Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature.

Risperidone may interact with other medicines and supplements. risperidone risperdal: uses, interactions and side effects Before using risperidone, tell your health care provider about any prescription or over-the-counter (OTC) medicines, vitamins/minerals, herbal products, and other supplements you are using. People who are 65 or older can be at greater risk for some side effects from risperidone.

Talk to your health care provider about your risks if you are in this age group. Risperidone can affect your ability to regulate your body temperature. This could make you very hot, especially in hot weather or after exercising a lot.

Although there are no mandatory requirements for therapeutic drug monitoring with risperidone, monitoring plasma concentrations for this medication is strongly recommended by European guidelines because of data showing interdependent variability. Therapeutic monitoring can benefit from assessing compliance and identifying low drug concentrations that may be low, resulting in therapeutic failure. Also, monitoring the drug level can aid in evaluating potential drug interactions and adverse effects. Although these adverse effects are thought to be reversible, the duration of Parkinsonian features after discontinuation of the medication can vary. Tardive dyskinesia, however, will likely persist after the medication is discontinued and may be permanent. In addition to discontinuation of the antipsychotic, pharmacologic treatments are available that may help with certain extrapyramidal symptoms.1718 One potential adverse effect of risperidone is orthostatic hypotension.
