question: My dad (82) showed sudden temper flares, mood swings and aggressive behaviour. Psychiatrist prescribed oleanz rapitab 2.5 initially once a day. That did not change his behaviour. After 4 days he was taken to the doctor again. Dosage was increased to 5mg twice daily. Now after 5 more days of increased dosage, he is his usual calm and quiet self. How long should he take the medication? Will one month s treatment be enough? He doesn t have diabetes or hypertension. Will taking this drug increase the risk of diabetes or hypertension?
