Modafinil, armodafinil, solriamfetol, and pitolisant are common medical medicines used to increase alertness in conditions like narcolepsy or shift-work sleep disorder. Treating underlying issues like sleep apnea or bad sleeping patterns is sometimes just as crucial. Modafinil-containing products like modvigil 200 may improve alertness, but they should only be taken under a doctor's supervision to guarantee safety and the right dosage for each patient.
