A "smart pill" for narcolepsy is often a wake-promoting drug that also helps with concentration. Modvigil 200 mg, a generic version of modafinil, is a popular choice that improves alertness and lessens excessive daytime drowsiness. Additional drugs include armodafinil and, occasionally, sodium oxybate or stimulants. Because each person's efficacy and side effects are different, always use them under a doctor's supervision.
