Milsaperidone
Bysanti
Start with a clear dose schedule, and give your body time to adjust.
Draft for review · Clinical content has not been revalidated for this website.
Food is optional. Different conditions and medicine combinations require different starting schedules.
What it is used for
Treats schizophrenia in adults, and acute manic or mixed episodes in adults with bipolar I disorder.
It is not approved for bipolar depression or for children. Ask which symptoms you and your prescriber will use to judge progress.
How it works
It changes dopamine and serotonin signaling involved in symptoms. Your body also changes some of it into the related medicine iloperidone.
The small diagram is a simplified model, not a promise about each receptor's benefit. Do not swap medicines on your own.
What to expect over time
STARTING DAYS
The dose rises in steps to lower the chance of dizziness or fainting. Do not increase faster.
NEXT FEW WEEKS
Track sleep, thoughts, mood, and daily function. Sleepiness alone does not show that symptoms are improving.
ONGOING CARE
Keep visits and health checks. Tell your team about missed days, new medicines, or troublesome effects.
Taking your medication
Take the prescribed morning and evening doses, with or without food. Check the tablet strengths against your written schedule.
Your schedule may be lower because of other medicines, liver health, or how your body processes the drug. Do not copy someone else's schedule.
If you miss more than three days, call before restarting: the dose must be increased gradually again. Never double a dose.
When to get help
Emergency help: collapse, seizure, breathing trouble, facial/throat swelling, or fever with severe stiffness and confusion.
Urgent assessment: fainting, heart fluttering with dizziness, or a painful or prolonged erection. Do not wait for a routine visit.
Prompt advice: uncontrolled movements, fever/infection, marked thirst, or frequent urination. Seek emergency help if you cannot stay safe.
Early side effects
Dizziness, sleepiness, a faster pulse, dry mouth, stuffy nose, or tiredness can occur. Stand up slowly and report repeated lightheadedness. Wait to drive until you know how it affects you.
Other effects to discuss
Weight, blood sugar, cholesterol, and prolactin may rise. Report tremor, stiffness, restlessness, involuntary movements, sexual changes, missed periods, or milk discharge.
What to keep track of
Expect weight, blood pressure, pulse, blood sugar, cholesterol, and movement checks. Your risks may call for heart-tracing, electrolyte, liver, or blood-count tests. Bring your medicine list to every visit.
Before you start
Mention allergies, fainting, heart-rhythm problems, stroke, diabetes, low blood counts, seizures, swallowing trouble, liver/kidney disease, pregnancy and nursing. Tell your eye surgeon about current or past use before eye surgery. Antipsychotics raise death and stroke risks in older people with dementia-related psychosis; Bysanti is not approved for that condition.
Medicines & interactions
Some antidepressants and antifungals
Medicines such as fluoxetine, paroxetine, or ketoconazole can require a lower Bysanti dose. Ask before starting or stopping them.
Medicines that affect heart rhythm
Some combinations should be avoided. Check antibiotics, other psychiatric medicines, and every new prescription with your pharmacist.
Blood-pressure and prostate medicines
Alpha-blockers should be avoided with Bysanti. Other medicines that lower blood pressure may need adjustment.
Alcohol, sedatives, and supplements
Avoid alcohol. Check sleep aids, other sedatives, grapefruit, and supplements before use; they may change effects or drug levels.
Everyday tips
Keep the starting schedule where you take your medicine. Ask the pharmacist to explain any dose that needs more than one tablet.
Sit or lie down if dizzy. Avoid overheating and dehydration; follow any fluid restrictions from your clinician.
Ask before restarting after a break or changing another medicine. The same previous dose may no longer be the right starting dose.
Tell someone you trust what changes to watch for. Call if sleep, behavior, mood, or safety worsens between visits.
Your questions, answered
What if I miss a dose?
Do not double. Ask your pharmacist how to handle a missed dose, especially during the starting schedule. More than three missed days requires restarting titration.
Can I stop when I feel better?
Make a plan with your prescriber. Symptoms can return; troublesome side effects are a reason to call rather than manage alone.
What about pregnancy?
Contact your team if pregnant or planning pregnancy. Discuss illness and medicine risks, newborn monitoring, and the pregnancy registry; do not stop abruptly.
Can I breastfeed?
The label advises no breastfeeding during treatment, then a wait of six or eight days after the last dose, depending on metabolism. Ask your team which applies and arrange feeding support.
Storage & safety
Store at room temperature, protected from light and moisture and away from children/pets. Do not share. For an extra dose call Poison Control at 1-800-222-1222; call 911 for collapse, seizure, breathing trouble, or inability to wake.
