Molindone
Oral tablets / formerly sold as Moban
An antipsychotic for schizophrenia. Review symptom relief and movement effects together.
Draft for review · Clinical content has not been revalidated for this website.
D2 has a supported role. The D3 action label still needs verification; alpha2 binding has no established separate clinical benefit.
What it is used for
Molindone is approved to treat schizophrenia. It may help hallucinations, suspicious beliefs, and disorganized thinking, but response varies from person to person.
It is not approved for dementia-related psychosis. Antipsychotics increase the risk of death in older adults with that condition; discuss alternatives with the team.
How it works
It blocks dopamine D2 receptors. This can reduce psychotic symptoms, but can also cause restlessness, stiffness, and hormone-related effects.
The whole treatment effect is not explained by one receptor. Other targets in the diagram do not prove extra benefits or predict how the medicine will feel.
What to expect over time
EARLY DAYS
Sleepiness or dizziness may begin early. Dose changes depend on symptoms and side effects. Do not increase the dose yourself.
OVER WEEKS
Some symptoms may improve within a week; fuller benefit takes several weeks. Track daily function, hallucinations, and suspiciousness.
EACH REVIEW
An urge to keep moving may be akathisia, a side effect, not worsening illness. Tell your team so the cause and treatment can be reviewed.
Taking your medication
Take the agreed divided doses consistently, usually three or four times daily. Use the schedule on your prescription; do not combine doses on your own.
Avoid alcohol and driving until effects are known. Rise slowly. Avoid overheating or dehydration, including during strenuous exercise.
Check before adding medicines, including sleep or allergy products. Do not stop abruptly. Plan refills early and call if tablets are unavailable.
When to get help
Stop and get emergency help: fever with severe muscle stiffness, confusion, sweating, or an unstable heartbeat may be neuroleptic malignant syndrome.
Emergency: trouble swallowing or breathing, throat/neck spasms, seizure, collapse, severe belly pain with vomiting, or a prolonged painful erection.
Call promptly: new mouth/tongue or other involuntary movements, fever/sore throat, jaundice, rash, severe restlessness, or inability to pass urine.
Early side effects
Drowsiness, dizziness, dry mouth, blurred vision, nausea, or constipation can occur. Report falls, persistent sleepiness, and bowel symptoms early.
Other effects to discuss
Discuss breast changes, milk production, menstrual or sexual changes. Weight effects may be less than with some drugs, but metabolic checks still matter.
What to keep track of
Keep movement, weight, blood pressure, blood sugar, and cholesterol checks. Prior low white cells need closer blood-count monitoring. Report fever or infection signs promptly. Tell your team about depression, suicidal thoughts, or major behavior changes; get emergency help if you cannot stay safe. Ask someone you trust to notice changes.
Before you start
Review prior movement problems, Parkinson disease, or Lewy body dementia, seizures, falls, heart disease, glaucoma, constipation, urinary difficulty, and low white blood cells. Discuss breast cancer history, kidney/liver disease, pregnancy, feeding, and all medicines. Severe nervous-system depression or coma rules out use. Children below 12 do not have established safe and effective dosing.
Medicines & interactions
Alcohol, opioids, and sedatives
Alcohol, opioid pain medicines, sleep aids, and other sedatives can worsen sleepiness and impairment. Check before combining; do not drive if affected.
Phenytoin and tetracyclines
Calcium sulfate in the tablets can reduce absorption of phenytoin sodium and tetracycline antibiotics. Ask your pharmacist about timing and monitoring; there is no universal spacing rule in the label.
Bowel, bladder, and movement drugs
Anticholinergic medicines can worsen constipation, urinary difficulty, confusion, and some persistent movements. Do not add them automatically for restlessness or stiffness.
Blood-pressure medicines and lithium
Blood-pressure medicines may add dizziness or fainting. Lithium combinations need monitoring for nervous-system toxicity. Report new marked tremor, confusion, or unsteadiness promptly.
Procedures and new medicines
Tell dental, anesthesia, and emergency teams that you take molindone. Carry a full medicine list, including nonprescription products and supplements; check changes with your pharmacist.
Everyday tips
Use reminders for each prescribed dose time.
Track one or two symptoms and daily activities.
Keep movement checks even when symptoms improve.
Pair treatment with support, therapy, and routine.
Your questions, answered
What if I miss a dose?
Take it when remembered unless the next dose is nearly due; then skip. Never double. If several doses are missed, contact your team before restarting at your previous dose.
Can I stop when I feel better?
Plan a gradual taper with your prescriber to reduce relapse and rebound symptoms. A serious reaction is different and may require stopping urgently. Do not change treatment without advice.
What do new movements mean?
They need assessment. Some persistent movements, called tardive dyskinesia, may not fully go away. Treatment options exist; tell your team early rather than hiding movements or adding another drug yourself.
Pregnancy or breastfeeding?
Discuss an individual plan. Pregnancy evidence is limited; late exposure can affect newborn movement, breathing, or feeding. Milk and infant-safety data are unavailable in the reviewed sources; discuss alternatives and feeding with a specialist.
Storage & safety
Store tightly closed at room temperature, protected from light and moisture, secure from children and pets. Never share. Suspected overdose: call Poison Help, 1-800-222-1222, immediately. Call 911 for collapse, seizure, breathing trouble, inability to wake, or imminent self-harm. U.S. crisis support is also available through 988.
