It may also increase the risk of your kidneys not working as well as they should or cause high levels of potassium in your blood.

Can I take Pregabalin and Prozac together?
Taking pregabalin and Prozac (fluoxetine) together can increase the risk of side effects that affect your brain and nervous system. You may feel more drowsy, dizzy, or confused. It can also make it harder to concentrate or perform tasks that require alertness. In some cases, especially in older adults, it may lead to impaired thinking or coordination. There is also a small but serious risk of a rare condition called serotonin syndrome, which can cause shivering, sweating, and a fast heartbeat.
