Insurance Coverage
Typical coverage: Tier 2 generic — anticonvulsant related to carbamazepine but with fewer drug interactions
Most insurance plans use a tiered formulary: Tier 1 (generic) $0-$15 copay, Tier 2 (preferred brand) $25-$75, Tier 3 (non-preferred brand) $50-$150, Tier 4 (specialty) $100-$500+. Prior authorization may be required for certain medications. Step therapy may require trying cheaper alternatives first.
