Modalert 200mg Tablets (Modafinil): Strong Wakefulness & Alertness UK Guide
Modalert 200mg Tablets contain 200mg of modafinil as the active ingredient. Modafinil is a centrally acting wakefulness-promoting medication used in adults to improve excessive daytime sleepiness associated with narcolepsy, with or without cataplexy. The 200mg strength corresponds to the recommended starting daily dose for adults when modafinil is prescribed for this indication.
Modafinil is intended to improve daytime wakefulness in people with a diagnosed sleep disorder and should not be regarded as a replacement for adequate sleep or appropriate clinical management. Treatment should be initiated and supervised by a doctor with appropriate knowledge of sleep disorders, with the continued need for treatment reviewed regularly.
What Is Modalert 200 mg Used For?
- Narcolepsy: Modafinil is indicated for adults with excessive daytime sleepiness associated with narcolepsy, with or without cataplexy.
- Excessive Daytime Sleepiness: Modafinil helps improve wakefulness in adults who experience an abnormal tendency to become sleepy or fall asleep during normal daytime activities as a result of narcolepsy.
- Maintaining Wakefulness: Treatment can help patients remain awake and alert during periods when excessive sleepiness would otherwise interfere with normal daily functioning.
- Clinically Diagnosed Sleep Disorder: Modafinil should be used following appropriate medical assessment of excessive daytime sleepiness. It is not intended as a general-purpose treatment for tiredness caused by insufficient sleep.
How Does Modalert Work?
Modalert contains modafinil, a centrally acting wakefulness-promoting medication. Its complete mechanism of action is not fully established, but modafinil inhibits dopamine reuptake and affects neurotransmitter systems involved in the regulation of wakefulness. These effects increase wakefulness and reduce excessive daytime sleepiness in appropriately diagnosed patients. Modafinil does not replace normal sleep and should be used alongside appropriate management of the underlying sleep disorder. Modafinil has a relatively long elimination half-life, generally around 15 hours. This contributes to its prolonged wakefulness-promoting activity during the daytime when taken according to the prescribed schedule.
How to Take Modalert 200 mg Tablets
- Follow Your Prescription: Take Modalert exactly as prescribed by your doctor or sleep specialist. Treatment should be initiated and supervised by a healthcare professional experienced in managing the relevant sleep disorder.
- Recommended Adult Dose: The recommended starting dose for adults with narcolepsy is 200mg per day. This may be taken as a single dose in the morning or as two divided doses, one in the morning and one at noon.
- Dose Adjustment: If the response to 200mg is insufficient, a doctor may consider increasing the daily dose to a maximum of 400mg, provided the treatment is tolerated and the higher dose is clinically appropriate.
- Morning Administration: Modafinil is generally taken in the morning to promote daytime wakefulness and reduce the risk of interfering with nighttime sleep. If divided dosing is prescribed, the second dose is generally taken around noon.
- With or Without Food: Modafinil can be taken with or without food. Swallow the tablets with water and follow the administration instructions provided by your prescriber.
- Liver Problems: Patients with severe hepatic impairment generally require a reduced dose. Tell your doctor about any liver condition before starting treatment.
- Regular Treatment Review: Continued treatment should be reviewed periodically to determine whether it remains necessary and beneficial. Long-term treatment should remain under appropriate medical supervision.

- Hormonal Contraception: Modafinil can reduce the effectiveness of steroidal hormonal contraceptives. Women who can become pregnant should discuss appropriate contraception with their healthcare professional during treatment and for two months after stopping modafinil.
- Liver Function: Patients with severe liver impairment may require a reduced dose. Any existing liver condition should be discussed with the prescribing clinician.
- Kidney Function: Tell your doctor if you have kidney problems so that your suitability for treatment can be assessed.
- Dependence and Misuse: Modafinil has potential for misuse, abuse and dependence. It should only be taken by the person for whom it has been prescribed and should not be shared with others.
- Driving and Alertness: Modafinil may improve wakefulness but does not necessarily eliminate excessive sleepiness. Patients should not assume that they are safe to drive simply because they are taking modafinil. Follow medical advice and avoid driving if you remain excessively sleepy or experience dizziness, visual disturbances or other impairing effects.
Stopping Modalert Treatment
Do not change or stop Modalert treatment without discussing it with your prescribing clinician. Modafinil is generally used as part of ongoing management of a diagnosed sleep disorder, and the continued need for treatment should be reviewed regularly.
