Modafinil's exact mechanism is not fully understood, but it is believed to work primarily by inhibiting the reuptake of dopamine in the brain — increasing dopamine availability in synapses. It also influences norepinephrine, serotonin, histamine, and orexin (hypocretin) systems that regulate wakefulness and sleep-wake cycles. Unlike amphetamines, Modafinil does not cause widespread dopamine release, which explains its lower addiction potential and milder side effect profile. It promotes wakefulness by activating the hypothalamic wake-promoting regions while not suppressing REM sleep in the same way as traditional stimulants.
Always follow your doctor's prescription. General clinical guidelines: Narcolepsy & Sleep Apnoea: - Standard dose: 200 mg once daily in the morning - Some patients may require 400 mg (split or single dose) Shift Work Sleep Disorder: - 200 mg taken approximately 1 hour before the start of the work shift Dose titration: - 50 mg or 100 mg may be used as starting doses to assess tolerance - Dose adjustments should only be made under medical supervision Important: - Take with or without food (food may delay onset by ~1 hour) - Avoid taking in the afternoon or evening to prevent insomnia - Do not crush or split unless advised by your doctor - Swallow whole with a full glass of water

Controlled substance: Modafinil is a Schedule IV controlled substance in the USA. It requires a valid prescription and should be stored securely. Cardiovascular conditions: Use with caution in patients with a history of heart disease, hypertension, arrhythmia, or left ventricular hypertrophy. Regular BP monitoring is recommended. Psychiatric history: Use with caution in patients with anxiety disorders, psychosis, bipolar disorder, or history of substance abuse. Pregnancy & Breastfeeding: Not recommended. Modafinil may reduce the effectiveness of hormonal contraceptives — use alternative or additional contraception during treatment and for 2 months after.

Drug interactions: May reduce effectiveness of oral contraceptives, cyclosporine, and certain HIV medications. May interact with CYP3A4 substrates. Inform your doctor of all medications. Dependence & Withdrawal: Although lower than amphetamines, psychological dependence is possible with prolonged high-dose use. Do not stop abruptly without medical guidance. Driving & machinery: Modafinil may improve wakefulness but underlying sleepiness may still impair driving. Follow your doctor's advice before driving.
Q: What is Modafinil used for?

A: Modafinil is prescribed for narcolepsy, obstructive sleep apnoea (where CPAP is also used), and shift work sleep disorder. It is used off-label by some individuals to improve focus and cognitive performance.

Q: Is Modafinil the same as Provigil?

A: Yes. Provigil is the original brand name for Modafinil. Generic Modafinil contains the same active ingredient at equivalent bioavailability.

Q: How long does Modafinil last?

A: The wakefulness-promoting effects typically last 12–15 hours after a single dose. The half-life is approximately 12–15 hours.

Q: Can I take Modafinil every day?

A: For approved conditions, daily use is prescribed. However, long-term daily use should be monitored by a physician. Tolerance may develop with continuous use.

Q: Does Modafinil cause addiction?

A: Modafinil has a significantly lower addiction potential than traditional stimulants. However, psychological dependence is possible. It is classified as Schedule IV in the USA, reflecting its controlled status.

Q: Will Modafinil affect my sleep?

A: If taken as directed (morning or before a shift), it should not significantly disrupt nighttime sleep. Avoid taking it in the afternoon or evening.

Q: Which dose should I choose?

A: 200 mg is the standard prescribed dose for most adults. 50 mg or 100 mg may be used for dose titration or in elderly/sensitive patients. 400 mg is reserved for cases where 200 mg is insufficient. Always follow your doctor's prescription.
