Modafinil 400mg Australia is a prescription drug that is used for promoting alertness in people who have certain sleep-related disorders. This drug can be used in the treatment of excessive daytime sleepiness that is associated with narcolepsy, obstructive sleep apnoea or shift work sleep disorder. Modafinil works through influencing several neurotransmitter systems responsible for wakefulness, including dopamine systems, but its exact mechanism of action is unknown.


The 400mg dose per day is a high dose and not everyone needs this dose. The dose will depend on the particular medical condition, how well the body responds, personal medical history, and other medications that one is using. Patients should never take a larger dose than recommended by their doctors.


Adverse effects that have been reported include headache, nausea, dizziness, nervousness, anxiety, dry mouth and trouble sleeping. Rare skin or allergic reactions are also possible and they need immediate medical attention. Modafinil can interact with other medications and decrease the efficiency of hormonal birth control methods.


Modafinil does not substitute sufficient sleep or treatment of sleep disorders. Anyone who thinks of using this medication needs to undergo a proper medical assessment first.
