Lullan • Japanese product information
A plan for clearer thinking that also pays attention to how treatment feels.

What it is used for
Perospirone treats schizophrenia in Japan. It can help with distressing experiences such as hearing voices or feeling unusually suspicious.
Your team should explain the symptoms you are treating and what improvement might look like.
How it works
It changes dopamine and serotonin signaling. The small diagram describes some drug actions, not a promise about your individual response.
These actions can also affect movement, alertness, and hormones. Tell your team about changes.
What to expect over time
EARLY ON
Some changes can begin in the first week. Side effects may appear before clear benefit.
OVER SEVERAL WEEKS
Thinking and day-to-day function may improve gradually. Do not judge success by sleepiness.
AT FOLLOW-UP
Review both benefits and problems. If agitation or troubling thoughts worsen, contact your team sooner.
Taking your medication
Take the prescribed dose after meals, usually three times daily, with water. Remove tablets from the blister; never swallow the packaging.
If you forget, take the dose after a meal or light snack when remembered, unless the next dose is nearly due. Then skip it; never double.
Do not change or stop treatment on your own. After a longer gap, ask your prescriber how to restart.
When to get help
Emergency: seizure, collapse, trouble breathing, sudden chest pain, or fever with severe stiffness, confusion, or trouble swallowing.
Urgent advice: severe belly pain/constipation, a painful swollen leg, fever/sore throat, new uncontrolled movements, or muscle pain with dark urine.
Hold the medicine and seek immediate advice for extreme thirst or frequent urination. Vomiting, deep breathing, or confusion needs emergency care.
Early side effects
Stiffness, tremor, an urge to keep moving, sleepiness, insomnia, dizziness, nausea, and constipation can occur. Stand slowly. Japanese guidance says not to drive or use dangerous machinery while taking it.
Other effects to discuss
Weight, blood sugar, cholesterol, and prolactin can change. Report missed periods, breast changes, milk discharge, or sexual problems. New involuntary movements need prompt assessment, even if they are not painful.
What to keep track of
Keep weight, blood-pressure, blood sugar/cholesterol, and movement checks. Other tests depend on your health. Track sleep, bowel habits, and daily function. If you cannot stay safe, seek emergency help.
Before you start
Tell your team about allergies, kidney/liver or heart disease, low blood pressure, seizures, diabetes, low blood counts, Parkinson disease, Lewy body dementia, swallowing/bowel problems, dehydration, pregnancy or nursing. Mention past suicidal thoughts or attempts. It is not approved for dementia-related behavior problems; antipsychotics raise death and stroke risks in those older adults.
Medicines & interactions
Other prescriptions and supplements
Some antibiotics, antifungals, and seizure medicines change drug levels. Ask a pharmacist before adding or stopping any medicine, including nonprescription products.
Alcohol and sedating medicines
Avoid alcohol. Sleeping pills, other sedatives, and some allergy medicines can add sleepiness and impaired alertness. Blood-pressure medicines may add dizziness.
Parkinson, nausea, or stomach medicines
Levodopa may work less well. Metoclopramide or domperidone can add movement or hormone problems; cimetidine also needs an interaction check.
Dental and emergency treatment
Tell the dentist or emergency team you take perospirone. Epinephrine needs special consideration, but it remains allowed for emergency anaphylaxis treatment. Do not delay emergency care.
Everyday tips
Link doses to regular meals and use reminders. If the three-dose schedule is difficult, ask for help rather than combining doses.
Discuss a plan for activity, food, sleep, and constipation. Side effects that interfere with life deserve a treatment review.
Avoid overheating and dehydration, while following any fluid limits. Do not drink excessive water to manage a new, intense thirst; get medical advice.
Keep appointments even when you feel better. Arrange refills early and ask the pharmacy about any change in tablet supply or strength.
Your questions, answered
Is restlessness just my illness?
Not always. An inner urge to pace or move can be a side effect. Tell your team so it can be assessed before the dose is changed.
Can I stop when I feel better?
Plan changes with your prescriber. Stopping suddenly may bring symptoms back. Serious warning symptoms are different: seek urgent help and follow the instructions on the “When to get help” section.
What if I become pregnant?
Contact your team without stopping on your own. Discuss treatment and relapse risks. Babies exposed late in pregnancy may need feeding, breathing, and movement monitoring.
Can I breastfeed?
Human safety information is limited. Discuss treatment and feeding options. If nursing continues, watch for unusual sleepiness, poor feeding, breathing problems, or abnormal movements.
Storage & safety
Store at room temperature, away from sunlight, moisture, children and pets. Do not share; ask a pharmacy about disposal. For an extra dose, contact a poison center or urgent medical service; collapse, seizure, or breathing trouble needs your local emergency number.
