What it is

Armodafinil, brand name Nuvigil, is the R-enantiomer of modafinil, marketed for narcolepsy, shift-work sleep disorder, and obstructive sleep apnea-related residual sleepiness.

Why the spread exists

Armodafinil came off patent in 2016 and several US generics exist, yet cash-pay prices remain elevated due to PBM rebate dynamics. International generic tablets, particularly Sun Pharma Waklert and HAB Pharma R-Modawake, trade at a fraction of US cash retail.

Brand vs generic

Bioequivalent generic armodafinil is widely available internationally. The molecule is identical. Brand pricing premium is preserved in the US by tier formulary and prior-authorization friction.

Regulatory status

Armodafinil is a Schedule IV controlled substance in the US. Personal importation considerations are stricter than for non-scheduled molecules. We surface the spread but make no claim about lawful import.
