Artvigil 150 mg

What Is Artvigil 150 mg

Artvigil 150 mg is a medication formulated to increase alertness and wakefulness. It helps in the reduction of excessive daytime sleepiness caused by disorders such as narcolepsy and obstructive sleep apnoea. It is also beneficial for those who are looking to boost their concentration because of work demands. It contains armodafinil, the R-enantiomer of modafinil. Armodafinil is a purified form of one of the two active components found in modafinil.

How Artvigil 150 mg Works?

Artvigil 150 mg helps promote wakefulness by affecting certain neurotransmitters in the brain. Its active ingredient, armodafinil, is believed to inhibit the dopamine transporter (DAT), increasing dopamine levels and helping improve alertness, concentration, and wakefulness. Although the exact mechanism of action is not fully understood, this effect helps reduce excessive daytime sleepiness associated with conditions such as narcolepsy, obstructive sleep apnoea, and shift work sleep disorder.

Uses

Armodafinil is used to improve wakefulness in people with certain sleep disorders, including:

• Narcolepsy
• Obstructive sleep apnoea
• Shift work sleep disorder

In some situations, your doctor may prescribe armodafinil for other conditions when they believe the potential benefits outweigh the risks. These are considered off-label uses.

Dosage

The advised dose as per the recommendations of medical experts is one tablet in 24 hours duration, and it should not be exceeded to avoid critical side effects. However, the exact dosage will be instructed by your doctor depending on the severity of your condition.

• For those suffering from a sleeping disorder such as narcolepsy, one tablet should be taken during the day.
• For people who need medications for their shift work disorder, a tablet should be taken one to two hours before the start of your job. This ensures that peak levels of the medication are achieved in the bloodstream before its action is required.

The effects of Artvigil generally last between 10 and 14 hours, although this can vary depending on factors such as age, metabolism, overall health, and individual response. You should consult a doctor before using these tablets if you suffer from any medical condition.

Missed Dosage

In case you miss a dose, take one as soon as you remember. However, if you do not need to stay awake for the next few hours, or plan on falling asleep, skip the dose entirely and resume the treatment the next day. You can consult your doctor for further assistance in such a case.

Note: Do not take two tablets to compensate for the missed dosage as it may result in serious side effects.

Overdose

Overdosing may result in serious health problems such as breathing difficulties, fluctuations in heart rate, hallucinations, etc, which may turn into life-threatening conditions. In case of any such accidents, seek immediate medical care.
