Modalert 100mg (Modafinil Tablets)

Description

What Is Modalert 100mg?

Modalert 100mg is a branded modafinil tablet. Sun Pharmaceutical Industries’ official India product catalogue lists MODALERT 100 MG TABLET with modafinil, a strength of 100mg and tablet dosage form within its NEURO/CNS portfolio.

This catalogue evidence supports the association between the Modalert brand, modafinil, the 100mg strength and tablet dosage form. It does not by itself establish an Australian registration, Australian-approved indications or a particular manufacturing site.

The strength is important because modafinil products may be available in different strengths. However, a 100mg tablet strength should not be interpreted as meaning that 100mg is the standard or appropriate daily dose for every person.

Modafinil treatment requires assessment of the underlying cause of excessive sleepiness. An appropriately qualified healthcare professional should also consider medical history, other medicines and individual clinical circumstances.

Modalert 100mg vs Modafinil: What Is the Difference?

Modalert and modafinil describe related but different things.

Modalert 100mg is a branded finished tablet product listed by Sun Pharmaceutical Industries with modafinil at a strength of 100mg. Modafinil is the active pharmaceutical ingredient associated with the product’s pharmacological effects.

Other branded products may also be presented or labelled as containing modafinil. They should not automatically be considered identical to Modalert 100mg, as products can differ in strength, formulation, excipients, appearance, packaging and regulatory status.

For related educational context on the distinction between a branded finished product and its active ingredient, see Modvigil 200mg vs Modafinil.

This distinction is particularly important in Australia. Australian registration applies to the exact therapeutic good entered in the Australian Register of Therapeutic Goods (ARTG). The registration of another modafinil product does not establish that Modalert 100mg has the same Australian regulatory status.

What Is Modafinil Used For?

Modafinil is used in recognised medical settings involving excessive daytime sleepiness. Australian regulatory and clinical information concerning modafinil includes medical contexts such as narcolepsy, obstructive sleep apnoea/hypopnoea syndrome as part of broader management, and chronic shift work sleep disorder in appropriately selected patients.

For obstructive sleep apnoea, wakefulness-promoting treatment addresses excessive sleepiness rather than the underlying airway obstruction. Appropriate management of the underlying condition, including CPAP where prescribed or recommended, remains important.

These are ingredient-level and registered-product clinical contexts. They do not establish that Modalert 100mg itself has Australian-approved indications or ARTG registration.

For broader ingredient-level educational context, see Modvigil 200mg uses, benefits and side effects.

Recognised medical use of modafinil should also be distinguished from online claims concerning studying, gaming, general productivity or cognitive enhancement in healthy people. Evidence that modafinil promotes wakefulness in particular medical conditions does not establish those non-medical purposes as approved Australian indications for Modalert.

How Does Modafinil Promote Wakefulness?

The pharmacological effects relevant to Modalert 100mg relate to its listed active ingredient, modafinil.

Modafinil acts within the central nervous system, although its precise mechanism remains incompletely understood. Research indicates that modafinil affects several neural and neurotransmitter systems involved in wakefulness, including effects involving dopamine signalling.

Wakefulness promotion should not be interpreted as a guarantee of improved intelligence, memory, judgement, academic performance or workplace productivity. Modafinil does not replace adequate sleep or appropriate treatment of an underlying sleep disorder.

Understanding the 100mg Strength

Modalert 100mg is listed as a 100mg modafinil tablet, but tablet strength and an individual’s prescribed daily dose are different concepts.

The appropriate modafinil treatment regimen depends on clinical factors such as the diagnosed condition, individual response, medical history, liver function, age-related considerations and other medicines being used.

Australian prescribing information for specific registered modafinil products may contain product-specific dosing recommendations and dose-adjustment guidance. That information should not be treated as Modalert-specific prescribing instructions.

A healthcare professional should determine the appropriate dose and treatment schedule for the individual patient. The 100mg tablet strength should never be used on its own to select or modify a dose.

For readers comparing strengths within the same branded product family, see Modalert 200mg. The existence of 100mg and 200mg listings does not establish that the two products are interchangeable or that two 100mg tablets should automatically be substituted for one 200mg tablet.

How to Use Modalert 100mg

Modalert 100mg should be used according to the instructions provided by the prescribing healthcare professional and valid product-specific labelling supplied with the medicine.

The Sun Pharmaceutical Industries product catalogue confirms the product name, modafinil, 100mg strength and tablet dosage form but does not establish detailed administration instructions such as whether a tablet should be divided, crushed, taken with food or taken at a particular time.

Patients should therefore follow their individual medical instructions rather than relying on general modafinil guidance to determine how to take Modalert.

Buying Modalert 100mg Online: What Australian Readers Should Know

Searches for Modalert 100mg online often involve questions about prescription requirements and personal importation. In Australia, these issues are governed by medicine scheduling and import rules.

Modafinil is a Schedule 4 Prescription Only Medicine in Australia. This scheduling status relates to modafinil and does not itself establish ARTG registration for the Modalert finished product.

The TGA’s Personal Importation Scheme may allow individuals to import certain therapeutic goods that are not entered in the ARTG when all applicable conditions are met.

For a prescription-only medicine, current TGA guidance states that the importer must hold a valid Australian prescription or written authority at the time of importation. The written authority must meet the TGA’s requirements and correspond with the medicine being imported.

For prescription-only medicines, a single import must not exceed a three-month supply at the maximum prescribed dose. The total quantity imported within any 12-month period must not exceed a 15-month supply.

Current TGA guidance also advises ordering only what has been prescribed and providing the overseas seller with a copy of the written authority for inclusion with the package. Other documentation may also be required.

All Personal Importation Scheme conditions must be satisfied. Goods may also be subject to Australian Border Force, Customs, quarantine or controlled-substance restrictions, so eligibility under the scheme is not a blanket guarantee that every product or shipment can lawfully enter Australia.

For a related product-verification framework, see what to check before ordering Modvigil 200mg online.

When assessing an overseas product, check the product name, listed ingredient, strength, dosage form, labelling, expiry information and applicable prescription and import requirements. Packaging and visual consistency can help identify a product but do not independently prove authenticity, composition, pharmaceutical quality or regulatory approval.

The TGA advises that products imported under the Personal Importation Scheme are not evaluated by the TGA, meaning their safety, quality and efficacy cannot be guaranteed and they may not meet Australian standards. This is a general warning about personally imported therapeutic goods and should not be interpreted as a finding that Modalert itself is counterfeit or substandard.

Counterfeit therapeutic goods are prohibited from importation under the scheme, including where the importer holds a prescription or was unaware that the goods were counterfeit.

Possible Side Effects

Common Side Effects

Modafinil can cause side effects. Reported effects include headache, nausea, nervousness or anxiety, difficulty sleeping, dizziness and gastrointestinal symptoms.

Not everyone experiences these effects, and their type and severity can vary between individuals.

For broader ingredient-level safety information, see Modvigil 200mg side effects.

Serious Side Effects

Serious reactions have been reported with modafinil, including severe skin reactions, hypersensitivity reactions, significant psychiatric symptoms and cardiovascular problems.

Seek prompt medical attention for serious or unexpected symptoms, particularly a severe or spreading rash, facial or throat swelling, difficulty breathing, chest pain, marked changes in mood or behaviour, hallucinations or suicidal thoughts.

These warnings relate to modafinil safety information and should not be interpreted as independent Modalert-specific pharmacovigilance data.

Important Precautions

Before modafinil treatment begins, a healthcare professional should know about relevant medical conditions and all prescription, non-prescription and complementary medicines being used.

Heart and Blood Pressure

Cardiovascular history, including high blood pressure or other heart-related conditions, should be discussed before modafinil treatment. A healthcare professional can determine whether assessment or monitoring is required.

Mental Health

A history of depression, mania, psychosis, significant anxiety, substance misuse or other important psychiatric conditions should also be discussed before treatment.

Allergic and Skin Reactions

Serious skin and hypersensitivity reactions have been reported with modafinil. A new or spreading rash, particularly when accompanied by fever, facial swelling, breathing difficulty or other systemic symptoms, requires prompt medical assessment.

Pregnancy

Australian regulatory information for the registered modafinil product MODAVIGIL was updated in 2025 to include pregnancy in its contraindications and to strengthen information concerning fetal harm, congenital malformations and spontaneous abortion. The TGA provides updated pregnancy safety information for modafinil.

This MODAVIGIL regulatory update should not be interpreted as Modalert Product Information. However, anyone who is pregnant, planning pregnancy or becomes pregnant while receiving modafinil should seek medical advice promptly.

Breastfeeding

People who are breastfeeding or planning to breastfeed should discuss modafinil treatment with their healthcare professional. Pregnancy safety information should not automatically be assumed to provide identical breastfeeding guidance.

Driving and Operating Machinery

An underlying sleep disorder can itself impair alertness, and individual responses to modafinil treatment vary. Patients should understand how both their condition and treatment affect them before driving, operating machinery or performing other safety-sensitive tasks.

Drug and Medicine Interactions

Modafinil may affect the metabolism or effects of other medicines. Potentially relevant interactions include medicines such as warfarin, certain anti-epileptic medicines, some antidepressants, diazepam, cyclosporin and other medicines affected by liver-enzyme pathways.

The clinical significance of an interaction depends on the medicines involved and the individual’s circumstances. Patients should provide their doctor or pharmacist with a complete list of prescription medicines, over-the-counter medicines, vitamins, supplements and herbal products.

Hormonal Contraception

Modafinil can interact with hormonal contraception and may reduce the effectiveness of some hormonal contraceptive methods.

People using hormonal contraception should discuss appropriate contraceptive advice, including whether an alternative or additional method is required and how long precautions should continue after modafinil is stopped, with their healthcare professional.

This approach avoids applying product-specific MODAVIGIL prescribing instructions to Modalert without verified Modalert-specific information.

Storage Instructions

• Follow the storage instructions supplied on the Modalert product packaging or label.
• Keep the medicine in its supplied packaging where appropriate.
• Keep medicines out of sight and reach of children.
• Do not use the product after the expiry date shown on the packaging.

Exact Modalert-specific storage conditions should be taken from valid product information rather than inferred from general medicine-storage guidance.

Modalert 100mg in Australia

It is important to distinguish the Australian regulatory status of modafinil from the status of Modalert 100mg as a specific branded product.

Modafinil is a Schedule 4 Prescription Only Medicine in Australia. Australian-registered modafinil therapeutic goods also exist, but registration applies to each exact product entered in the ARTG.

The registration or Product Information of another modafinil medicine, including MODAVIGIL, does not establish ARTG registration, Australian-approved indications or Australian Product Information for Modalert 100mg.

Australians considering an overseas Modalert product should check current regulatory and import requirements and obtain appropriate professional advice before arranging access.

Responsible Use

Modafinil treatment should follow appropriate medical assessment and professional guidance. Patients should use Modalert 100mg according to their prescriber’s instructions and valid product-specific information, avoid independently changing the dose or treatment schedule, and never share prescription medicines with another person.

Adequate sleep and appropriate management of an underlying sleep disorder remain important. Persistent or worsening sleepiness should be reviewed by a healthcare professional, particularly where it may affect driving, work or other safety-sensitive activities.
