Is Modafinil Good for Sleep Apnea?
Yes, modafinil for sleep apnea is indeed the best therapy since it’s approved to treat the condition. Consider that in OSA, the modafinil tab isn’t a cure for the underlying obstruction. Also, if diagnosed with severe hepatic impairment, the modafinil dose should be lessened by half.
Based on research, the modafinil tab significantly enhanced subjective sleepiness in patients diagnosed with untreated mild to moderate OSA . It remarkably lessens residual excessive daytime sleepiness (EDS) in patients with OSA treated with continuous positive airway pressure (CPAP). Thus, modafinil is indeed suggested to patients with OSA, specifically those with EDS.

Modafinil is available in doses of 100 & 200 mg. The 200 mg is the normal dosage indicated to ameliorate wakefulness in adults (17+ years) with excessive sleepiness linked with OSA. However, modafinil sleep apnea dosage of up to 400 mg/day, administered as a single dose, is also safe & well-tolerated in some individuals, but there is no consistent proof that the 400 mg dose offers added benefit exceeding that of the 200 mg/day dose .
