Modafinil 400mg Australia is a strong dosage of modafinil, which is an FDA approved drug prescribed to improve wakefulness in patients. Modafinil is used to treat sleep disorders such as narcolepsy, obstructive sleep apnea syndrome and shift work sleep disorder. Modafinil affects various brain neurotransmitter systems that regulate alertness, although the exact way it functions is not clear.

It is important to consult your doctor regarding the dosage of 400mg because the right amount depends on the underlying condition, how you respond to treatment and other medications you take. In most of the indications for which it is prescribed, the standard prescribing information suggests taking a smaller dose each day since there is no additional effect with high doses. Therefore, it should never be taken without medical advice.

Headache, nausea, nervousness, dizziness and insomnia are common side effects associated with modafinil. Others include anxiety, dry mouth and loss of appetite. Serious but rare side effects include severe skin or allergic reactions. Thus, it is important to seek medical help in case of symptoms like blisters on the skin, swelling, trouble breathing and widespread rashes.

Modafinil can cause drug interactions. Modafinil can decrease the efficiency of oral hormonal contraception and some drugs metabolized through the P450 liver enzymes. Patients must inform the doctor about any prescribed drugs, nutritional supplements, and underlying illnesses before receiving the medication.

Modafinil is not a replacement for getting enough sleep and can only be used for the medical purpose intended. Modafinil must always be taken according to the instructions of a health professional.
