Uses of Modafinil 200 Mg Tablet

Modafinil 200 mg tablet has been approved by the TGA for use in cases of –

• Narcolepsy patients (patients who suffer from extreme sleepiness during the day)
• Shift worker sleep disorder (patients who face difficulty with sleep during abrupt shifts)

However, the same is also prescribed by many doctors (with or without any other drug) for the treatment of OSA (obstructive sleep apnea) caused by the stoppage of breath during sleep.

How Does Modafinil 200 Work?

Modafinil affects brain neurotransmitters such as dopamine, helping regulate the sleep–wake cycle. It keeps you alert and mentally sharp without causing intense stimulation or crashes.

Modafinil targets the areas of the brain that work for regulating the cycle of sleep-wake. Along with that, the drug stimulates the levels of dopamine and norepinephrine (alertness stimulators in the brain).

With the increase of dopamine, mood of the patient is regulated by Modafinil. On the other hand, norepinephrine increases alertness and mindfulness in the patient. Hence, both of them work to increase the attention and focus of the patient, associated with the control over the sleep-wake cycle.

Is Generic Modafinil Effective?

Different clinical and lab tests suggested that Modafinil 200 mg remains active and keeps a patient active for 10-12 hours abruptly. However, the timing might differ with some other conditions.

Modafinil 200 is well well-tolerated drug with minimal adverse effects. Within these 10-12 hours, a patient remains fully focused, balanced, and active.

Thus, keeping in view the lab test results, it can be declared that Modafinil is not only effective, but also highly effective. Shift workers especially have a great report for modafinil.
