Dextroamphetamine Sulfate: Uses, Side Warnings, & More

What Is Dextroamphetamine Sulfate?

Dextroamphetamine sulfate, classified as a stimulant, is a medication primarily used for ADHD medication for ages 6 to 17 years old and narcolepsy. It is the active ingredient in several brand-name medications including Dexedrine and Zenzedi. It works by enhancing certain brain chemicals to improve focus and control impulsivity in individuals with ADHD. It is known to have neurological effects such as increased alertness and attention. Common side effects encompass nausea, stomach upset, loss of appetite, headache, trouble sleeping, and restlessness. It’s important to note that dizziness, weight loss, and irritability are also possible reactions.¹  

How Does Dextroamphetamine Sulfate Work?

Dextroamphetamine sulfate works by affecting brain chemicals like dopamine and norepinephrine, which help with paying attention and controlling impulses.² This medication boosts the amount of these chemicals, making it easier for the brain to focus and be less hyperactive, which in turn helps reduce ADHD symptoms.

This better balance of brain chemicals can lead to improved concentration, less restlessness, and better control over impulses, all of which together make ADHD symptoms better.

What Is Dextroamphetamine Sulfate Used to Treat?

Dextroamphetamine sulfate is FDA-approved for treating attention-deficit hyperactivity disorder (ADHD), which means it’s been tested and proven safe and effective for this purpose. Dextroamphetamine sulfate can also be used for narcolepsy, a rare sleep disorder. While it’s not common in children under 12, if they have narcolepsy, doctors might consider using dextroamphetamine sulfate. Before starting treatment, it’s always best to consult your doctor.

Interactions With Dextroamphetamine Sulfate

When taking dextroamphetamine sulfate, it’s important to be aware of potentially harmful interactions with other medications, substances, and herbs that could affect its effectiveness and safety.

20 substances you should avoid while taking dextroamphetamine sulfate include:¹

• MAO inhibitors: Mixing MAOIs with dextroamphetamine sulfate can lead to severe high blood pressure, headaches, and even dangerous reactions in the nervous system.
• Serotonergic drugs: Using dextroamphetamine sulfate with drugs that affect serotonin levels, like certain antidepressants, can cause a condition called serotonin syndrome. This can result in agitation, confusion, and even life-threatening symptoms
• CYP2D6 inhibitors: When taken together, these inhibitors can increase the effects of dextroamphetamine sulfate and raise the risk of serotonin syndrome.
• Acidifying agents: Some medications that make the digestive system more acidic can reduce how well amphetamines are absorbed, making them less effective.
• Adrenergic blockers: These are medications that block the effects of adrenaline. When combined with amphetamines, their effectiveness can be reduced.
• Alkalinizing agents: These substances can make the digestive system having a higher pH and increase the absorption of amphetamines, potentially leading to stronger effects.
• Antidepressants, tricyclic: These medications, when mixed with amphetamines, can increase the concentration of amphetamines in the brain, potentially causing cardiovascular effects.
• Antihistamines: Antihistamines can reduce concentration and focus.
• Antihypertensives: Medications used to lower high blood pressure might have reduced effects when taken with amphetamines.
• Chlorpromazine: This medication, used to treat certain mental health conditions, can block the effects of amphetamines and is sometimes used to treat certain symptoms of amphetamine toxicity.
• Ethosuximide: Amphetamines can slow down the absorption of this medication used for seizures.
• Lithium carbonate: The stimulating effects of amphetamines may be lessened by lithium carbonate.
• Norepinephrine: Amphetamines can enhance the effects of norepinephrine, a hormone that affects various body functions.
• Phenobarbital: The absorption of phenobarbital, used for seizures, may be delayed when taken with amphetamines.
• Phenytoin: Similar to phenobarbital, the absorption of phenytoin can be slowed down by amphetamines.
• Propoxyphene: In cases of overdose, the stimulation caused by amphetamines can lead to dangerous convulsions.
• Veratrum alkaloids: Amphetamines can lessen the blood pressure-lowering effects of veratrum alkaloids.

Can You Become Addicted to Dextroamphetamine Sulfate?

Dextroamphetamine sulfate carries a risk of addiction due to its classification as a Schedule II controlled substance known for potential abuse and dependency. (FN3) Misuse of these amphetamines can result in higher required doses, psychological dependence, and disruptions in daily life.

Healthcare providers should carefully monitor, prescribe appropriate doses, and assess ongoing necessity, along with setting limits, scheduling follow-up visits, and maintaining open patient-provider dialogue to deter misuse.

If dependence emerges, supervised discontinuation or structured detoxification may be necessary for a safe transition, emphasizing collaboration with healthcare professionals to manage these risks effectively.
