Not true: Side effects of prilosec are very rare and tend to occur in sick and hospitalized patients. If pepcid (famotidine) doesn't work and prilosec does work then stick with prilosec. You can have you magnesium check every few years for reassurance.

A recent metaanalysis revealed only 36 reported cases of symptomatic magnesium deficiency in the literature, which responded quickly to stoping the PPI.
