What is Modafinil?

Modafinil (or Provigil Modafinil) is a eugeroic drug used to treat narcolepsy, shift work sleep disorder and other long-term sleeping problems. There is no cure for narcolepsy, but Modafinil can help successfully manage your symptoms.

It’s possible to buy Modafinil online from online pharmacies, but you must first obtain a prescription from your doctor. Generic Modafinil is sometimes also called Modalert and Modvigil. You can also buy Modafinil under the brand name Provigil.

There are other, similar drugs available to treat sleep disorders, such as Armodafinil or Waklert, which you can buy from a pharmacy or other Modafinil vendor.

For more information on Modafinil, please read the patient information leaflet.

How it works

How Modafinil works isn’t fully understood, but it is understood that it acts like a stimulant to promote wakefulness. Some studies suggest that Modafinil increases the production of histamine, which increases your alertness. New studies suggest that Modafinil increases dopamine production in the brain, keeping you more awake.

Modafinil isn’t intended to treat sleep apnea.

Modafinil has been dubbed the “first safe smart drug in the world,” as it can act in the same way as nootropics do. This means it is theorised to promote high quality cognitive function. Buying Modafinil or Provigil online, or any other “smart drugs” for this purpose may be unsafe.

You should not order Provigil online for any other purpose than for which it has been prescribed to you, and it is not medically approved to improve cognitive function.

Before you take it

Modafinil may be addictive. Some studies have suggested that it affects dopamine transporters in the brain in a similar way to highly addictive stimulants such as cocaine and methamphetamine.

If you take too much Modafinil, it may make it difficult for you to fall asleep. Staying awake for too long can cause adverse health effects.

If you have narcolepsy, it can be dangerous for you to drive or operate heavy machinery. You are required to inform the DVLA if you have been diagnosed with narcolepsy. It may be possible for you to drive again if your symptoms are well controlled with Modafinil, but cannot do this without regular review. Modafinil can affect your reaction times, so you should avoid driving while taking Modafinil.

Modafinil should never replace a good sleep routine. You should not use Modafinil as a stimulant to stay awake for longer than you normally would. It is still important for you to get a full 7-8 hours sleep per night.

Modafinil has been known to affect hormonal contraception and to make it less effective. This includes intrauterine devices, contraceptive pills, contraceptive patches and implants. There is no guarantee that hormonal contraception will work effectively while taking Modafinil, and it’s best to speak to your doctor to discuss alternatives.

Our ordering limit for Modafinil is 60 tablets per month. If you order again before one month has passed, we will hold your order until a month has passed until your previous order.

Modafinil use is not recommended for women who are pregnant or trying to get pregnant. You must ensure that you use effective contraception while you are taking Modafinil. If you become pregnant while you’re taking Modafinil, you must consult your doctor to discuss effective management.

You should not consume alcohol while also taking Modafinil, as alcohol can make any side effects associated with Modafinil even worse.

If you are receiving any type of medical treatment, you must inform your doctor, who will be able to give you further advice. It’s safe to take Modafinil with painkilling drugs, including Paracetamol and Ibuprofen.

Dosage Instructions

You should take Modafinil exactly as prescribed by your doctor or consultant. You can take Modafinil before or after eating. Take your tablets with plenty of water.

Modafinil pills come in two different strengths - 100mg and 200mg per pill. Take 200mg daily, either as one dose in the morning or divided into two doses (100 mg in the morning and 100 mg at midday)

You must swallow a Modafinil 200 mg or 100 mg pill whole - do not crush, chew or suck it.

You may be prescribed a smaller dose, to check how your body reacts to Modafinil and how effective it is. If this is the case, follow the dosage instructions given to you by your doctor or pharmacist.

If you are elderly, your dose may need to be reduced. A typical daily dose for elderly patients is 100mg daily.

Common Side Effects of Modafinil

Frequently Asked Questions (FAQs)

What happens if I miss a dose?

If you have not taken your regular dose of Modafinil, treat it as a missed dose and take your next dose as scheduled. Do not take the dose at any other time, and do not double up to make up for a missed dose.
