Gabapentin and Lyrica synergistic effects?

What are your opinions on using gabapentin AND pregabalin at the same time in select patients? Apparently there may be some synergistic effects? Just saw a patient from a different provider on the combo and they say they have been on them both for years... Never heard of it in my training and I was kinda shocked to see it.
