Annie,

My B12 was normal in a very recent test (pernicious anemia runs in my family so I have maintained my B12 supplements over the past 5-8 years including at times patches). I am on Mestonin 60 mg 3 times a day and on Ventolin for my asthma. I currently live in the Orlando area, but will be moving closer to my elderly parents on the East coast, so St. Pete is about a 3 hour drive from that area. I researched conflicting meds with Mestonin before I started taking it and Neurontin wasn't on the list. Does it counteract the effects of the Mestonin?
