Modafinil Vs Adderall

Modafinil and Adderall are common stimulants used in the treatment of narcolepsy and covertly. Even though Modafinil is not classified as a stimulant, they both have stimulant effects. But, their structure is different, and this translates to massive differences in their addiction potential as well as side effects.

These drugs increase wakefulness, alertness, and motivation in people with hyperactivity disorder (ADHD), narcolepsy, and other disorders. While Adderall has been approved by FDA, Modafinil is prescribed off label (using drugs that aren’t FDA labeled or inserted) by psychiatrists.

Both drugs attract interest from people who need them for their health and other reasons. Here is a guide on their side effects, dosage and withdrawals so that users can distinguish the differences.

Modafinil vs. Adderall Overview

Adderall works by targeting one’s central nervous system. As it has both amphetamine and dextroamphetamine, it boosts dopamine levels that lift users’ moods. Studies say that it’s a commonly misused and abused drug among high school and college students. It increases one’s energy levels, alertness, and concentration. As such, many individuals use this stimulant for achieving high academic performance. Others also use it for staying awake for longer hours. But although Adderall is used for all these reasons, it shouldn’t be taken lightly. It’s highly addictive and can lead to severe withdrawal symptoms.

Modafinil (Provigil) treats excessive sleep, which results from narcolepsy. It’s mostly sold in Canada and the US as scheduled IV controlled substance. Individuals mostly use it because of its cognitive enhancing benefits such as boosting mental acuity and focus in people with attention disorders.

Components and Mechanism of Actions

Modafinil contains variants of 2-[(diphenylmethyl)sulfinyl] acetamide in equal proportions. These two molecules have different properties. Experts aren’t sure of how Provigil works but studies claim, it blocks dopamine transporter hence preventing dopamine uptake in an individual’s brain, therefore increases availability. Also, by partially activating dopamine D1 and D2 receptors, this drug increases dopamine levels, thereby promoting wakefulness, motivation, cognitive thinking, and even confidence.

Adderall has four amphetamine salts in equal proportions: dextroamphetamine (d-amphetamine) saccharate, D-amphetamine sulfate, Levoamphetamine (l-amphetamine) sulfate and L-amphetamine aspartate.

It’s said that this stimulant triggers the release of neurotransmitters including norepinephrine, adrenaline, and dopamine. It also prevents these neurotransmitters from being taken up, broken down, and stored inside nerve cells. Additionally, Adderall prevents dopamine from being stored into cell compartments. These processes, therefore, boosts users’ energy and concentration.

Which Has the Most Side Effects?

Modafinil doesn’t cause severe side effects as compared to those reported by Adderall users. Provigil can significantly increase heart rate and blood pressure. Therefore, individuals with a history of any heart or heart valve conditions such as ventricular hypertrophy shouldn’t take it.

Approximately, 1/3 of people who use Modafinil report headaches and 11% report nausea. Other adverse effects include gastrointestinal problems such as diarrhea, nervousness, anxiety, rhinitis, and back pain.

Again, this drug can make hormonal contraceptives with progestogen and estrogen less effective as it interferes with the enzymes converting these hormones into their active form. Some people also report life-threatening rushes such as Stevens – Johnson syndrome and Drug-Induced Hypersensitivity Syndrome.

Despite Provigil being around for many years, experts remain uncertain of its long term effects on one’s brain. But some people argue that it can cause chronic sleep deprivation and increased anti-socialness as it does suppress emotions.

Adderall, on the other hand, has many side effects. Note that these effects may be more severe in different people. 36% of users report loss of appetite while 35% report dry mouth and short-lived blood pressure elevations. Other side effects include insomnia, abdominal pain, and increased heart rate, slow growth among children, nervousness, and even disturbances in how someone functions sexually.

Individuals who’re highly sensitive to stimulants might develop confused thoughts even if they take small dosages. Side effects that have been reported by psychiatrists include suspicious for no particular reason, hearing voices and becoming manic.

Also, patients with glaucoma, overactive thyroid, heart disease, blood pressure, and a history of drug addiction should not use this stimulant. One of the main concerns is that Adderall can cause dependence and tolerance, and if suddenly stopped, it can cause severe withdrawal symptoms.

Also, note that neither of these two drugs should be mixed with alcohol. Even though alcohol is a depressant and the drugs are stimulating, that doesn’t mean that they’ll cancel each other’s effects. Instead, they’ll send mixed signals to your brain and can thus cause blackouts and certain heart complications such as arrhythmias.
