When a product is described as Modasmart 400mg, the 400mg figure refers to the stated amount of modafinil. This is a higher amount than a 200mg strength, but a higher strength should not automatically be interpreted as being more suitable or more effective for every person.



Modafinil is a prescription medicine used to promote wakefulness in certain medical conditions. Australian medicine information lists its use for excessive daytime sleepiness associated with narcolepsy, certain chronic shift work sleep disorder cases and as an adjunct to CPAP for obstructive sleep apnoea/hypopnoea syndrome.



When considering a higher strength, the medical reason for treatment is particularly important. A healthcare professional may consider the person's diagnosis, response to treatment, other medicines and overall health before deciding on an appropriate regimen.



It is also important to distinguish between general information about a 400mg modafinil dose and the regulatory status of a specific product marketed with the name Modasmart 400mg. The fact that a particular amount may be used in prescribing does not by itself confirm that every product sold under a particular brand name has the same Australian registration or supply status.



Australian consumers should remember that modafinil is Schedule 4 prescription-only medicine.
