Risperdal is prescribed for the treatment of psychotic disorders (schizophrenia).
Risperdal is prescribed in combination with lithium or valproate for the treatment of acute manic or mixed episodes associated with bipolar I disorder.
Risperdal is prescribed for the treatment of schizophrenia, a severe mental disorder that can cause delusions (false beliefs) and hallucinations. It is also prescribed for the short-term treatment of mania associated with bipolar disorder. Risperdal is thought to work by muting the impact of dopamine and serotonin, two of the brain's key chemical messengers.
Risperdal usually is begun as two small doses each day.
The doses often are increased every few days or each week until
the optimal dose is found. Patients who are elderly or have kidney
disease may need lower doses since the kidneys, which are partially responsible for removing Risperdal from the
blood, remove Risperdal more slowly, and this can lead to toxic levels of Risperdal in the
Similarly, patients with liver disease may need lower doses
since the liver also is partially responsible for removing Risperdal.
Doses of Risperdal can be taken once a day, or divided in half and taken twice daily. The usual dose on the first day is 2 mg or 2 ml of oral solution. On the second day, the dose increases to 4 mg or ml, and on the third day rises to 6 mg or ml. Further dosage adjustments can be made at intervals of 1 week. Over the long term, typical daily doses range from 2 to 8 mg or ml.
BIPOLAR MANIA (SHORT-TERM TREATMENT OF ACUTE EPISODES)
The recommended starting dose is 2 to 3 mg (or ml of oral solution) per day, given as a single dose. If needed, the doctor will adjust the dose by 1 mg at intervals of at least 24 hours. The effective dosage range is 1 to 6 mg a day.
The doctor may prescribe lower doses if you are weak, elderly, have liver or kidney disease, or have a high risk for low blood pressure. The usual starting dose is 0.5 mg (or 0.5 ml of oral solution) twice a day. The doctor may switch you to a once-a-day dosing schedule after the first 2 to 3 days of treatment.
If needed, each dose may be increased by increments of no more than 0.5 mg. Increases to dosages above 1.5 mg twice a day should generally me made at intervals of at least 1 week.
You may also need your Risperdal dose adjusted if you're taking certain medications, including Dilantin, Paxil, phenobarbital, Prozac, Rifadin, and Tegretol.
