There may be a slightly increased risk of serious, possibly fatal side effects (such as heart failure, fast/irregular heartbeat, pneumonia) when this medication is used by older adults with dementia. This medication is not approved for the treatment of dementia-related behavior problems. Discuss the risks and benefits of this medication, as well as other effective and possibly safer treatments for dementia-related behavior problems, with the doctor.Who should not take molindone?
Molindone is used to treat certain mental/mood disorders (such as schizophrenia). This medicine helps you to think more clearly, feel less nervous, and take part in everyday life. It can reduce aggression and the desire to hurt yourself/others. It may also help to decrease hallucinations (such as hearing/seeing things that are not there). Molindone is a psychiatric medication (antipsychotic-type) that works by helping to restore the balance of certain natural substances (such as dopamine) in the brain.
Take this medication by mouth with or without food as directed by your doctor, usually 1 to 4 times daily.
The dosage is based on your medical condition and response to treatment. To reduce your risk of side effects such as drowsiness and shaking (tremor), your doctor may direct you to start this medication at a low dose and gradually increase your dose. Follow your doctor's directions carefully.
Molindone tablets contain a small amount of calcium, which can interfere with your body's ability to absorb certain drugs, especially if you take them around the same time. Examples of these drugs include quinolone antibiotics (such as ciprofloxacin, levofloxacin), tetracycline antibiotics (such as doxycycline, minocycline), levodopa, phenytoin, thyroid medications (such as levothyroxine), and drugs for osteoporosis (bisphosphonates such as alendronate). Ask your doctor or pharmacist how long to wait between doses and when you should take your medications.
Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day. Do not stop taking this medication without consulting your doctor. Your condition may become worse when this drug is suddenly stopped. Your doctor may reduce your dose gradually.
Although you may notice some improvement in your symptoms soon after starting this medication, it may take several weeks to months before you get the full benefit of this drug.
Tell your doctor if your condition does not get better or if it gets worse.

Drowsiness, dizziness, constipation, dry mouth, or blurred vision may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.
This drug may cause muscle/nervous system problems (extrapyramidal symptoms-EPS). Your doctor may prescribe a medication to decrease these side effects. Tell your doctor right away if you notice any of the following side effects: stiff muscles, severe muscle spasm/cramping (such as twisting neck, arching back, eyes rolling up), restlessness/constant need to move, shaking (tremor), slow/shuffling walk, drooling/trouble swallowing, mask-like expression of the face.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor right away if you have any serious side effects, including: depression/suicidal thoughts, fainting, difficulty urinating, signs of infection (such as sore throat that doesn't go away, fever), symptoms of liver disease (such as nausea/vomiting that doesn't stop, loss of appetite, yellowing eyes/skin), severe stomach/abdominal pain.
This medication may cause a condition called tardive dyskinesia. In some cases, this condition may be permanent. Tell your doctor right away if you develop any unusual uncontrolled movements (especially of the face, mouth, tongue, arms, or legs).
In rare cases, molindone may increase your level of a certain chemical made by the body (prolactin). For females, this increase in prolactin may result in unwanted breast milk, missed/stopped periods, or difficulty becoming pregnant. For males, it may result in decreased sexual ability, inability to produce sperm, or enlarged breasts. If you develop any of these symptoms, tell your doctor right away.
Rarely, males may have a painful or prolonged erection lasting 4 or more hours. If this occurs, stop using this drug and get medical help right away, or permanent problems could occur.
Get medical help right away if you have any very serious side effects, including: seizures.
