What is Modafinil and what does it do?

Modafinil may be prescribed to adults who suffer from narcolepsy to help them stay awake. Modafinil is a wakefulness-promoting agent that acts on the central nervous system.

Narcolepsy is a neurological disease which affects how the brain regulates sleep and alertness. Narcolepsy can cause excessive daytime sleepiness and sudden, inappropriate sleep attacks throughout the day.

When is Modafinil prescribed?

Modafinil is indicated for the treatment of narcolepsy. There is no cure for narcolepsy, but modafinil may help to relieve the symptoms.

Narcolepsy is a rare long term disorder that can affect both men and women. Symptoms usually develop during adolescence, but can also develop later on in life.

Common symptoms of narcolepsy include:

  • Excessive daytime sleepiness.
  • Sleep attacks, often associated with sedate or repetitive activities.
  • Cataplexy (sudden, temporary muscle weakness or loss of muscle control).
  • Sleep paralysis (temporary inability to move or speak upon wakening).

A number of other symptoms are also associated with narcolepsy, such as hallucinations, headaches, restless sleep, memory problems and depression.

Is Modafinil suitable for my condition?

This depends on your medical history and whether you are taking any other medication. Some conditions and medicines can affect the suitability of modafinil and may lead to an increased risk of side effects.

Modafinil may not be prescribed if any of the following applies to you:

  • If you are allergic to modafinil or any of the other ingredients listed in the patient information leaflet.
  • If you have an irregular heartbeat.
  • If you have uncontrolled, moderate or high blood pressure.
  • If you have depression, low mood, anxiety, psychosis, mania or bipolar disorder. Modafinil may make these conditions worse.

Modafinil and hormonal contraceptives

Modafinil reduces the effectiveness of hormonal contraceptives, such as the contraceptive pill (‘the pill’), implants, IUDs (‘coil’) and patches. You will need to consider other birth control methods while taking modafinil and up to two months after stopping the treatment.

What is the recommended dosage of Modafinil?

You should follow the doctor’s instructions on how to take this medicine. The doses outlined below is for your reference only. Swallow the tablets whole with water.

Never exceed the stated dose.

Modafinil doses for adults

The usual dose is 200mg per day. This dose can be taken once in the morning, or divided into two 100mg doses morning and midday.

Modafinil doses for elderly (aged over 65)

The usual dose is 100mg per day. This dose can be taken once in the morning, or divided into two 50mg doses morning and midday.

Does Modafinil cause any side effects?

  • Headache
  • Dizziness.
  • Sleepiness, extreme tiredness or difficulty sleeping (insomnia).
  • Chest pain.
  • Flushing.
  • Loss of appetite, feeling sick, stomach pain, indigestion or constipation.
  • Numbness or tingling of the hands or feet.

Contact your doctor or GP immediately if you experience any symptoms that could indicate an allergic reaction, such as difficulty breathing, swelling of face, mouth or throat, skin rash or itching.

Can I reduce the risk of getting side effects?

Yes. You should always read the patient information leaflet thoroughly before use as this can help reduce the risk of side effects and interactions between medicines. Below are a few things you can do:
