What are Modafinil 100mg Tablets?

Modafinil 100mg Tablets contain 100 mg of modafinil, a prescription-only medicine authorised in the EU only for excessive daytime sleepiness in adults with narcolepsy (EMA: modafinil referral). The EU product information gives 200 mg a day as the usual dose and names 100 mg for older people and those with severe liver impairment; which dose suits you is a doctor's decision. Where zopiclone-type medicines sedate, modafinil acts on the brain's wake-promoting pathways. It complements, but never replaces, proper sleep — our sleep hygiene guide explains why.

How long do Modafinil 100mg Tablets take to work, and how long do they last?

Modafinil is absorbed over a few hours, and its half-life of around 12 to 15 hours applies at every strength, so even this lower dose remains active into the evening if taken late. The product information describes taking it in the morning, or split between morning and noon. Take no more than the dose your doctor has set in 24 hours, and read the patient information leaflet before your first tablet.

Modafinil 100mg Tablets vs Modafinil 200mg — what is the difference?

Only the amount of modafinil per tablet. Modafinil 200mg Tablets contain the usual daily dose in the EU product information for narcolepsy; 100 mg is the dose it names for older people and those with severe liver impairment. Headache, insomnia, anxiety and palpitations become more common as the dose rises, and any change of dose is your doctor's decision. Armodafinil is not authorised in the EU; our modafinil vs armodafinil guide compares them properly.

What should you know before taking Modafinil 100mg Tablets?

Read the leaflet before the first tablet, and take modafinil at the times your doctor sets — the product information describes morning dosing, or morning and noon. Do not take extra tablets within 24 hours. Caffeine can add to jitteriness or palpitations. Modafinil can make hormonal contraception less reliable, so ask a doctor about alternatives if relevant, and stop immediately and seek medical help if any rash appears. Anyone with heart, blood pressure or psychiatric conditions should get medical advice before taking modafinil at all.

Why buy Modafinil 100mg Tablets from Kam4eu?

Our Modafinil 100mg arrives as sealed manufacturer stock: blisters with the batch number and expiry date visible, an unopened carton, and the patient information leaflet inside. Packs start at €58.00 for 20 pills. Orders are dispatched within one working day of payment in plain, unbranded packaging, with tracking on every parcel; standard delivery takes 3–5 working days to most EU and EEA countries (2–7 by country) and is free over €110. Modafinil is a prescription-only medicine in the EU/EEA, authorised only for narcolepsy: get a doctor's assessment and a valid prescription first.

What are the side effects of Modafinil 100mg Tablets?

Headache is the most frequently reported side effect of Modafinil 100mg Tablets, alongside nausea, reduced appetite, dry mouth, mild anxiety and trouble sleeping when dosed too late in the day. Some users notice dizziness or a slightly elevated heart rate. Side effects become more likely as the dose rises. Rare but serious reactions require urgent care: a spreading or blistering skin rash or mouth ulcers (possible Stevens–Johnson syndrome), swelling of the face, lips or throat, chest pain, palpitations, or new depression, agitation or suicidal thinking — stop the tablets and seek medical help immediately.

Who should not take Modafinil 100mg Tablets?

Avoid Modafinil 100mg Tablets if you have previously reacted to modafinil or armodafinil with a rash or allergy, or if you have uncontrolled hypertension, significant arrhythmias, or heart problems linked to stimulant medicines. Even at this lower strength, caution is needed with anxiety, psychiatric conditions, and liver or kidney impairment — the EU product information names 100 mg for severe liver impairment. Key interactions: modafinil weakens hormonal contraception (use an extra barrier method during treatment and for two months after), and it alters blood levels of some antidepressants, anticonvulsants, ciclosporin and warfarin-type anticoagulants. Not recommended during pregnancy, breastfeeding, or for anyone under 18. Always confirm suitability with a doctor before starting.

How should you store Modafinil 100mg Tablets and check it's genuine?

Keep Modafinil 100mg Tablets in the original sealed blister, inside its carton, in a cool dry place below 25–30°C — away from window sills, radiators and humid bathrooms. Store it out of children's reach. Genuine packs are easy to verify: the blister foil should be uniformly sealed with no lifted corners, each pocket unbroken, and a printed batch number plus expiry date on the strip that matches the outer box. A manufacturer's information leaflet belongs in every carton. If tablets look crumbled or discoloured, or the packaging shows any sign of tampering in transit, photograph it and contact our support team before use.

What does Modafinil 100mg Tablets cost? Price per tablet explained

Current prices: 20 pills for €58.00 (€2.90 per pill), 30 pills for €86.00 (€2.87 per pill), 50 pills for €138.00 (€2.76 per pill) and 100 pills for €265.00 (€2.65 per pill). Buying 100 pills works out 9% cheaper per pill than the smallest pack. Buy only what your prescription covers before the printed expiry date.

About Modafinil

General information about the active ingredient in Modafinil 100mg Tablets.

See the full Modafinil guide & all Modafinil products

What is Modafinil?

Modafinil is a prescription-only medicine in the EU/EEA that promotes wakefulness. Since a 2010 European Medicines Agency review, its EU use is restricted to adults with excessive sleepiness caused by narcolepsy, with or without cataplexy; the EMA concluded it should no longer be used for obstructive sleep apnoea, shift-work sleep disorder or idiopathic hypersomnia.

How it works

Modafinil acts on the central nervous system to promote wakefulness and reduce excessive daytime sleepiness. Its exact mechanism is not fully understood, but it is thought to influence several chemical messengers in the brain involved in regulating the sleep-wake cycle, including dopamine. It helps you stay awake but does not replace a proper night's sleep.

How to take it

Take modafinil exactly as prescribed and follow the patient information leaflet. The EU product information says the daily dose is taken either once in the morning or split between the morning and noon, and that treatment is started by, or under the supervision of, a doctor with appropriate knowledge of narcolepsy. To avoid difficulty sleeping, do not take it late in the day, and keep good sleep habits: modafinil is not a replacement for sleep.

Side effects

Common (usually mild and temporary):

  • Headache
  • Difficulty sleeping (insomnia), especially if taken late in the day
  • Nausea or other stomach upset
  • Nervousness, anxiety or feeling jittery
  • Dizziness
  • Dry mouth

Stop and seek medical help if you experience:

  • A serious skin or hypersensitivity reaction (rash, blistering, peeling skin, mouth sores or facial swelling) — stop taking it and seek urgent medical attention
  • Chest pain, or a fast, pounding or irregular heartbeat
  • New or worsening mental-health symptoms such as anxiety, depression, hallucinations, agitation or thoughts of self-harm
  • Signs of a severe allergic reaction, including difficulty breathing or swelling of the throat
  • Yellowing of the skin or eyes, or other signs of liver problems

Safety & who should not take it

  • Modafinil can reduce the effectiveness of hormonal contraception (pill, patch, implant and some intrauterine systems); use an additional or alternative non-hormonal method during treatment and for up to two months after stopping.
  • Must not be used with uncontrolled moderate-to-severe high blood pressure or heart-rhythm problems; the EU product information recommends an ECG before starting and regular blood-pressure and heart-rate checks during treatment.
  • Stop taking modafinil and seek urgent medical help if you develop a rash or any signs of a skin or allergic reaction, which can rarely be serious.
  • Tell your doctor about all other medicines, as modafinil interacts with many drugs, including some for blood pressure, mood, epilepsy and blood clotting.
  • Avoid or limit caffeine and other stimulants, which may add to nervousness, a fast heartbeat and difficulty sleeping.
  • Tell your doctor about any history of mental-health problems, liver or kidney disease, or alcohol or drug misuse before starting.
  • Not for anyone under 18. Should not be used during pregnancy (the EU product information was updated after a 2019 EMA PRAC review of possible birth defects); women who could become pregnant need effective contraception during treatment and for two months after stopping. Should not be used while breastfeeding.

Storage

Store in the original packaging at room temperature, below 25°C, away from moisture and direct light, out of the sight and reach of children. Return unused tablets to a pharmacy for safe disposal.

Frequently asked questions

Does modafinil affect the contraceptive pill?+

Yes. Modafinil can reduce the effectiveness of hormonal contraceptives, increasing the risk of unintended pregnancy. Use an additional or alternative non-hormonal method during treatment and for up to two months after stopping, and discuss this with your doctor.

Will modafinil replace the need for sleep?+

No. It reduces excessive sleepiness and promotes wakefulness but does not remove your body's need for sleep or treat the underlying cause of tiredness. Continue any other treatment your doctor has recommended.

Why might modafinil keep me awake at night?+

Because it promotes wakefulness, taking it too late in the day can make it hard to fall asleep. It is usually taken in the morning to lower this risk. If insomnia is a problem, speak to your doctor rather than changing the timing yourself.

Is Modafinil 100mg Tablets discreetly packaged?+

Yes. Every order ships in plain, unbranded outer packaging — nothing on the outside indicates the contents or the pharmacy.

Is Modafinil 100mg a recognised dose?+

Yes. The EU product information gives 200 mg a day as the usual dose for narcolepsy and names 100 mg for older people and those with severe liver impairment. Which dose suits you is your doctor's decision.

Is Modafinil 100mg or 200mg the right dose for me?+

That is your doctor's decision. Side effects like headache, insomnia and anxiety increase with dose, and the EU product information gives 200 mg a day as the usual dose for narcolepsy, with 100 mg for some patients.

What time of day should I take Modafinil 100mg?+

The EU product information describes taking modafinil in the morning, or split between morning and noon, because it stays active for most of the day. Afternoon or evening doses commonly cause insomnia. Follow the times your doctor sets.

Does Modafinil 100mg affect the contraceptive pill?+

It can. Modafinil speeds up the breakdown of hormonal contraceptives, which may make pills, patches, and some implants less reliable during use and for a period after stopping. If you rely on hormonal contraception, talk to your doctor about additional or alternative methods before starting modafinil at any strength.

Are there side effects at the 100mg modafinil dose?+

Yes — headache is the most common, along with nausea, reduced appetite, anxiety and trouble sleeping if taken late. Rarely, modafinil causes serious skin reactions: stop immediately and seek medical help if any rash develops. The patient leaflet lists everything in full.

Can I take Modafinil 100mg with food?+

Modafinil can be taken with or without food; food may slightly delay its effect. Your doctor and the package leaflet set when to take it.

How long does Modafinil 100mg stay in your system?+

With a half-life of about 12–15 hours, a morning dose is substantially cleared overnight. Traces remain detectable for two to three days. A late dose can disturb that night's sleep.

Who is the 100 mg modafinil dose used for?+

The EU product information names 100 mg for older people and for those with severe liver impairment, within its narcolepsy-only use. Whether it is the right dose for you is your doctor's decision; don't change the dose yourself.

Does Modafinil 100mg interact with the contraceptive pill?+

Yes, even at 100mg. Modafinil accelerates the breakdown of hormonal contraceptives, reducing their reliability — this applies to pills, patches, rings and implants. Use an additional barrier method throughout treatment and for two months after stopping, and talk to your doctor about alternatives if you use modafinil regularly.

Does Modafinil 100mg expire?+

Yes — check the expiry date printed on both the blister strip and the carton. Do not take expired tablets, and keep them sealed in the blister, below 25–30°C and dry, until then.
