Patient's Query

Hello doctor,

I was taking Pregabalin for a long time. I got my blood test done and B12 has come 1993 pg/ml although the LFT and RFT are normal. Should I stop the intake of Pregabalin immediately and wait for fifteen days to get the B12 test once again?

Hello,

Welcome to icliniq.com.

Pregabalin medication is used for neuropathic pain. It does not lead to the elevation of B12. So, you can continue with this medication.

For high B12 level, you have already ruled out liver and kidney disease by their subsequent reports. So, I suggest you investigate with CBC (complete blood count) and peripheral smear examination blood report for further work up.

B12 is a water-soluble vitamin and it can readily be excreted through the kidneys. So, do not worry about that and investigate with CBC and peripheral smear examination report as suggested.

Same symptoms don't mean you have the same problem. Consult a doctor now!
