DESCRIPTION
Modalert 200 mg Tablet is a drug that helps people who have sleep disorders like narcolepsy, shift work sleep disorder, and obstructive sleep apnea and who are too sleepy during the day. It helps keep you awake by affecting some of the brain’s natural chemicals that control sleep and alertness.
When lower doses aren’t enough, this stronger version is given. It helps with focus, alertness, and daytime functioning.
Mechanism of action
Modafinil promotes wakefulness and alertness by the following mechanisms:
- Dopamine Transporter (DAT) Inhibition – Modafinil is thought to bind to the dopamine transporter and reduce dopamine reuptake. This may increase dopamine signaling in the brain and support wakefulness and alertness.
- Orexin activation – Modafinil may influence orexin pathways which are involved in regulating the sleep-wake cycle and maintaining daytime alertness.
- GABA regulation – Modafinil may reduce GABA activity in some brain regions. Since GABA is associated with sleep and relaxation this effect may help prevent drowsiness.
SIDE EFFECTS
Like all medicines, Modalert 200 mg can cause side effects although not everyone experiences them. Common effects are usually mild but should still be discussed with the GP if they persist or become troublesome. Commonly reported side effects include Headache, Nausea or stomach upset, Dry mouth and Dizziness.
Stop Taking It and Get Medical Advice If…
Stop using Modalert 200 mg and seek urgent medical advice if you develop signs of a serious reaction, including:

- Severe anxiety, confusion, hallucinations, aggression, or suicidal thoughts

Serious skin and allergic reactions are uncommon, but they require prompt attention. Do not restart the medicine unless a healthcare professional specifically tells you to do so.
Interactions
Modalert 200 mg can interact with several prescription medicines, over-the-counter products and hormonal treatments. Always provide your GP with a complete list of medicines and supplements you use.
Clinically relevant interactions may be:
- Hormonal contraceptives – Modafinil may decrease the effectiveness of hormonal contraceptives. Talk to your GP about reliable non-hormonal or other contraceptive protection while you are being treated and for a time afterwards.
- Blood thinners – Medicines such as warfarin may require closer monitoring.
- Anti-seizure medicines – Drugs including phenytoin may be affected.
- Some antidepressants and antipsychotics – May require dose adjustment or other monitoring.
- Sedatives and sleeping pills – may interact with modafinil to produce different effects
- Medicines for fungal infections, HIV, tuberculosis or problems with your heart rhythm – these medicines can affect how modafinil works, or increase the risk of side effects.

Precautions & Warnings
- Modalert 200 mg should only be used for a confirmed medical indication. It is not intended as a study aid, weight-loss medicine or replacement for sleep.
- People with obstructive sleep apnea should continue using prescribed therapies such as CPAP unless their sleep specialist advises otherwise. Modafinil may help manage residual sleepiness but it does not correct airway obstruction during sleep.
- Use caution if you have cardiovascular disease or a history of mental health conditions. Your doctor may check blood pressure, heart rate, mood and sleep pattern during treatment.
- Pregnancy should be discussed with a clinician before starting modafinil. Effective contraception planning is particularly important because the medicine can make certain hormonal contraceptives less reliable.
