Product introduction

OleANZ 10mg Injection is generally administered by a doctor or a nurse, typically in a hospital or clinical setting. Make sure to follow all your doctor’s instructions. Get the injection in the dose and duration as advised by your doctor. This medication must not be stopped suddenly without talking to your doctor, as it may worsen your symptoms.

Some common side effects of this medicine include dryness in the mouth, increased appetite, sleepiness, hard or infrequent stools, and restlessness. Initially, this medicine may cause a sudden drop in blood pressure when you change positions, so it is better to rise slowly if you have been sitting or lying down. It also causes dizziness and sleepiness, so do not drive or do anything that requires mental focus until you know how this medicine affects you.

However, this medicine may increase your weight, blood sugar, and cholesterol levels, but modifying your lifestyle by having a healthy diet and exercising regularly can reduce these side effects. You should be cautious, as in rare cases it may cause serious side effects like very high blood sugar levels or seizures.

How OleANZ Injection works

OleANZ 10mg Injection is an atypical antipsychotic. It works by affecting the levels of chemical messengers (dopamine and serotonin) to improve mood, thoughts, and behavior. It blocks dopamine (D₂) and serotonin (5-HT₂A) receptors in the brain, helping to balance these chemicals and reduce symptoms of schizophrenia and mania. Additionally, it interacts with other receptors, such as histamine and adrenergic receptors, which may contribute to its sedative effects.
