Summary
clozapine

Versacloz is a medicine used to treat severe schizophrenia when other medicines have not worked. It can also help lower the risk of suicidal behavior in people with schizophrenia or schizoaffective disorder.

repaglinide

Repaglinide (Prandin) helps control blood sugar in adults with type 2 diabetes. It works best when used with diet and exercise.

What It Treats
clozapine

Versacloz is used to treat schizophrenia in people who haven't responded well to other antipsychotic medicines. Schizophrenia is a mental illness that can cause hallucinations, delusions, and disorganized thinking. Versacloz can also help lower the risk of repeated suicidal behavior in people with schizophrenia or schizoaffective disorder who are at high risk.

repaglinide

Repaglinide is used to lower blood sugar in adults with type 2 diabetes. It should be used along with a healthy diet and regular exercise. This medicine is not for people with type 1 diabetes or diabetic ketoacidosis.

How It Works
clozapine

Versacloz works by affecting certain chemicals in the brain. These chemicals, like dopamine and serotonin, are involved in mood, behavior, and thinking. By changing the levels of these chemicals, Versacloz can help reduce symptoms of schizophrenia and lower the risk of suicidal behavior.

repaglinide

Repaglinide helps your pancreas release insulin after you eat. Insulin helps move sugar from your blood into your cells. This lowers your blood sugar levels.

Serious Warnings
clozapine

Versacloz can cause several serious side effects: * **Severe Neutropenia:** This means a dangerously low white blood cell count, which increases your risk of infection. You will need regular blood tests to check your white blood cell count. * **Orthostatic Hypotension, Bradycardia, and Syncope:** This means low blood pressure when standing up, slow heart rate, and fainting. These are most likely when you first start taking Versacloz or when the dose is increased. * **Seizures:** Versacloz can increase your risk of seizures, especially at higher doses. * **Myocarditis, Pericarditis, and Cardiomyopathy:** These are serious heart problems that can be fatal. Tell your doctor right away if you have chest pain, shortness of breath, or other heart-related symptoms. * **Increased Mortality in Elderly Patients with Dementia-Related Psychosis:** Elderly patients with dementia who take antipsychotic medicines like Versacloz have an increased risk of death.

repaglinide

Repaglinide can cause low blood sugar (hypoglycemia). If you skip a meal, skip your dose of repaglinide to avoid low blood sugar. Do not use repaglinide with NPH-insulin. There is no proof that repaglinide lowers your risk of heart problems.

Pregnancy
clozapine

Tell your doctor if you are pregnant or plan to become pregnant. Babies born to mothers who take Versacloz in the third trimester may have withdrawal symptoms or other problems after birth. There is a pregnancy registry for women who take atypical antipsychotics like Versacloz.

repaglinide

Tell your doctor if you are pregnant or plan to become pregnant. Poorly controlled diabetes during pregnancy can harm both the mother and the baby. Repaglinide is not recommended while breastfeeding due to the risk of low blood sugar in the baby.
