Switched from lorezepam to cirpalex and I'm experiencing side effects like nausea and shaking. Withdrawals from lorazepam or side effects from cipra?

See a doctor. Lorazepam withdrawal can be deadly. If a larger dose is stopped suddenly, it can lead to withdrawal and citalopram will not help that. There are also dangerous side effects from SSRIs like citalopram that can happen after first starting. Best advice is to seek medical care right away to avoid serious consequences.
