Side Effects and Safety Profile
Both modafinil and adrafinil can cause several side effects, which can be physical or mental. Additionally, they have some long-term health implications that users should be aware of.
Physical Side Effects
Common physical side effects for both modafinil and adrafinil include headache, nausea, and dry mouth. Users may also experience indigestion, diarrhea, and dizziness. Adrafinil, in particular, has been linked to liver toxicity due to its metabolic conversion to modafinil, which can strain the liver over time.
Some users report fever and gastralgia with adrafinil. Modafinil, though generally better tolerated, can still cause headaches, dry mouth, and indigestion. If physical side effects persist or worsen, individuals should consult a healthcare professional.
Mental Side Effects
Both drugs can impact mental states. Common mental side effects include anxiety, nervousness, and agitation. These can be mild or severe, depending on the individual’s sensitivity to the medication.
Modafinil users often report increased alertness and focus, but this can be accompanied by insomnia if taken too late in the day. Adrafinil can also cause anxiety and restlessness, though perhaps less intensely than modafinil due to its milder nature. Monitoring mental health symptoms is crucial for long-term use.
Long-Term Health Implications
Long-term use of adrafinil raises concerns about liver toxicity. Regular liver function tests are recommended for those using adrafinil chronically.
Modafinil, while considered safer, does require caution; long-term studies are still ongoing to fully understand its side effects. Both substances should be used under medical supervision to monitor their impact on liver function and overall health. Long-term use necessitates evaluating the benefits versus potential health risks, including dependency and tolerance.
Pharmacokinetics and Dosage
Modafinil and adrafinil have some differences in their pharmacokinetics and dosage.
Adrafinil is a prodrug, meaning it is converted in the body to modafinil. This conversion happens primarily in the liver. Adrafinil was originally developed by Lafon Laboratories. The onset of action for adrafinil takes longer because it needs to be metabolized first.
Modafinil is used directly and does not need conversion. This leads to a quicker onset of action.
Parameter | Modafinil | Adrafinil |
---|---|---|
Onset | 30-60 mins | 1-2 hours |
Peak Levels | 2-4 hours | 2-5 hours after conversion |
Half-Life | 12-15 hours | 5-10 hours (before conversion) |
Dosage | 200-400 mg/day | 300-600 mg/day |
Modafinil and adrafinil are both taken orally. Modafinil reaches its peak concentration in the blood within 2-4 hours and has a half-life of about 12-15 hours. The pharmacokinetics of modafinil are dose-independent between 200 and 600 mg/day.
Adrafinil is usually taken at a higher dose than modafinil, typically 300-600 mg/day, due to its conversion process.
Pharmacologically, modafinil and adrafinil work similarly once adrafinil is converted into modafinil. Both drugs promote wakefulness and alertness.

Regulations and Legal Status
Modafinil is a prescription medication in most countries. For instance, in South Africa, it is classified as a Schedule 6 drug. This classification means it is a prescription-only medication. Individuals need a doctor’s prescription to buy and use it legally.
In many countries, regulators strictly control its production and distribution. Importing modafinil without a valid prescription can lead to legal issues.
The World Anti-Doping Association (WADA) has also listed modafinil as a banned substance. Athletes must avoid it to prevent penalties or disqualification from competitions.
Adrafinil, by comparison, has a different legal status. It is not as heavily regulated as modafinil. In some places, it is legal to purchase without a prescription. This makes adrafinil easier to obtain for research purposes.
Additionally, adrafinil is a prodrug of modafinil. When taken, it converts to modafinil in the body, but the safety and legal structure can differ. Users should still exercise caution and consult medical professionals if side effects occur.
France is where adrafinil was originally developed. In France, it was once marketed as a prescription drug but is no longer available.
Safety, potential for abuse, and regulation are key issues influencing the legal status of these substances. Both have benefits and risks, so understanding the local laws and guidelines is crucial.
Comparative Costs
Modafinil, often sold under the brand name Provigil, can be expensive. With insurance, it might be more affordable, but the cost is still high. Generic modafinil brands like Modalert are cheaper. Prices can start at as low as $0.89 per 200mg pill.
Adrafinil is usually more affordable than modafinil. It can be bought without a prescription in some places, making it easier to purchase. This lower cost might make it an attractive option for many users.
Insurance often covers modafinil (Provigil) but not adrafinil. This coverage can significantly lower out-of-pocket costs for modafinil users. Conversely, people choosing adrafinil must pay the full price themselves.
A comparison of typical prices:
