goldenboys,
Inquire again. I cannot IMAGINE an insurance company allowing only lovastatin as the single statin in their pharmacopeia? It's very weak.
Ask about Lipitor, Pravachol, Crestor.
Alas, lovastatin is very cheap compared to the others, and a crummy insurance company might choose only on that basis. I assume you are STUCK with that company because it's what your employer offers, take it or leave it?
PErhaps the Zocor is allowed under the new generic formulation, simvastatin.
Gastritis, nausea, and headache really aren't what people see with statins. Maybe it's something else that's causing it?
