What is Caplyta?

Caplyta capsules contain lumateperone, an antipsychotic medicine.

Caplyta is a once-daily capsule used to control the symptoms of schizophrenia in adults.

Although the physical cause of schizophrenia is unknown, it is believed that imbalances between chemicals, such as dopamine, serotonin, and glutamate, in the brain is the probable cause. The exact way Caplyta works is unknown but it is thought to affect the balance of these brain-signaling chemicals to help control schizophrenia symptoms.

Warnings

Popular FAQ

Does Caplyta cause weight gain?

Caplyta treatment does not appear to be associated with the weight gain that some other antipsychotic drugs cause. 

Results from a number of trials combined together showed that the weight gain observed in patients treated with Caplyta was similar to the weight gain observed in patients who received placebo.

Positive results were also reported by a study that followed patients for one year after they switched from standard of care to Caplyta. Significant improvements in mean body weight were observed during the year of treatment with Caplyta (-2.1  kg, P <0.001) and significant reductions in body mass index (BMI) and waist circumference were also observed.

When should I take Caplyta?

Caplyta should be taken once a day with food. The recommended dosage of Caplyta is one 42mg capsule a day. Caplyta can cause somnolence and sedation, but these side effects are reported less frequently when Caplyta is taken in the evening.

How long does it take Caplyta to work?

After one week of treatment with Caplyta, patients enrolled in a phase III trial started to show improved Positive and Negative Syndrome Scale (PANSS) total scores. PANSS is a scale used to measure the severity of schizophrenia symptoms. Symptoms continue to improve the longer you take the drug.

While there may be some signs of improvement during the initial weeks of treatment, it can take up to 2-3 months for the full effects of Caplyta to be felt.

In the first 1-2 weeks, hallucinations, disorganized thinking and delusions may improve, although sometimes they won’t go away altogether. It can also take at least 1-2 weeks for motivation and the desire to be around other people to improve.
