Pregabalin is a safe medication and most people respond to a dose of 150-300 mg per day. However, doses unto 600 mg per day may be safe. Please watch for side effects such as dizziness, sleepiness, etc. which are common with over dosage of pregabalin. I hope it helps. Please get back if you require any additional information. Wishing you good health, Chat Doctor. Ly/ </s>
