How to use
Take it exactly as your doctor prescribed, at the same time each day. Swallow the tablet with water, with or without food. Your doctor may start with a low dose and increase it slowly.
How it works
It blocks dopamine and serotonin receptors in the brain. This helps rebalance these chemical messengers, which are involved in thinking, mood and perception.
