 Medically reviewed by Austin Ulrich, PharmD

Key Takeaways

• Amphetamine-dextroamphetamine (Adderall) is a stimulant used primarily to treat Attention-deficit hyperactivity disorder (ADHD) and narcolepsy.
• While it can be an effective treatment, it can cause side effects ranging from dry mouth and insomnia to more serious heart or mental health concerns.
• Amphetamine-dextroamphetamine is also a controlled substance and carries risks of dependence and misuse.
• Prescription discount programs like the Super+ RX coupon can help you save money on amphetamine-dextroamphetamine and other prescriptions.

Understanding Amphetamine-Dextroamphetamine

While many people know this medication as Adderall, the active ingredients are a combination of amphetamine and dextroamphetamine salts. These two stimulants work together to affect chemicals in the brain and nerves that contribute to hyperactivity and impulse control.

How It Works

Amphetamine-dextroamphetamine works by increasing the levels of dopamine and norepinephrine in the brain.

• Dopamine is associated with reward, attention, and movement.
• Norepinephrine affects attention and responding actions (the “fight or flight” response).

For people with certain conditions, these neurotransmitters may not work as efficiently as they should. By boosting their levels, amphetamine-dextroamphetamine helps improve focus, concentration, and listening skills while reducing impulsivity.

Conditions Treated

Amphetamine-dextroamphetamine is FDA-approved for two specific conditions:

• Attention-Deficit Hyperactivity Disorder (ADHD): It is often part of a total treatment program that also includes psychological, educational, and social measures. It helps increase the ability to pay attention, stay focused on an activity, and control behavior problems.
• Narcolepsy: This is a chronic sleep disorder characterized by overwhelming daytime drowsiness and sudden attacks of sleep. The stimulant properties of the amphetamine-dextroamphetamine help you stay awake and alert during the day.

Immediate Release vs. Extended Release

You will typically encounter this medication in two forms:

• Immediate-release (IR) amphetamine-dextroamphetamine (generic Adderall): These tablets release the medication into your system all at once. They typically last 4 to 6 hours and may be taken multiple times a day.
• Extended-release (ER) amphetamine-dextroamphetamine (generic Adderall XR): These capsules are designed to release the medication slowly over the course of the day. They usually last about 12 hours and are taken once in the morning.

Usage and Dosage Guidelines

Taking amphetamine-dextroamphetamine and other stimulants requires strict adherence to the instructions provided by your healthcare professional. Because this medication is a Schedule II controlled substance, there are specific legal and health guidelines regarding how it is prescribed and dispensed.

Proper Administration

For the medication to work effectively and safely, consistency is key.

• Timing: It is generally recommended to take the first dose upon awakening. Taking it later in the afternoon can lead to insomnia or restless sleep at night, especially if you are prescribed the ER version.
• With or Without Food: You can take this medication with or without food. However, it is important to be consistent. If you always take it with breakfast, stick to that routine.
• Swallowing: IR tablets should be swallowed whole. ER capsules should also ideally be swallowed whole. However, if you or a child has trouble swallowing pills, some ER capsules can be opened and the beads sprinkled over a spoonful of applesauce. This mixture must be swallowed immediately without chewing. Be sure to check with your prescriber or pharmacist to ensure this is a safe way to administer the medication you are prescribed.

Missed Doses

If you miss a dose, take it as soon as you remember. However, if it is already late in the day, skip the missed dose. Taking a dose too late in the day will likely keep you awake. Never take two doses at the same time to make up for a missed one.

Storage and Safety

Store the medication at room temperature, away from moisture, heat, and light. Because amphetamine-dextroamphetamine is a medication with a high potential for abuse and dependency, keep it in a secure place where others cannot access it. It is illegal and dangerous to share this prescription with anyone else, even if they have similar symptoms.

Side Effects and Risks

Every medication comes with a list of potential reactions, and stimulants are no exception. Being aware of Adderall side effects helps you monitor your health and know when to seek help. Most people tolerate the medication well when taken as prescribed, but everyone responds differently.

Common Side Effects

These effects are frequently reported but may resolve as your body adjusts to the medication:

• Digestive Issues: Loss of appetite, weight loss, stomach pain, nausea, or dry mouth.
• Sleep and Energy: Trouble sleeping (insomnia), restlessness, or nervousness.
• Physical Sensations: Headache, dizziness, or a slightly faster heart rate.

Serious Side Effects

While less common, some side effects require immediate attention. If you notice any of the following, contact your healthcare professional right away:

• Circulation Problems: Numbness, pain, feeling cold, or color changes (pale, red, or blue) in fingers or toes. This condition is sometimes referred to as Raynaud’s phenomenon.
• Heart Issues: Pounding/fast/irregular heartbeat, chest pain, or shortness of breath.
• Mental/Mood Changes: Agitation, aggression, mood swings, depression, or hallucinations.
• Uncontrollable Movements: Muscle twitches (tics).

Serotonin Syndrome

Rarely, this medication can cause a serious condition called serotonin syndrome, especially if taken with other medications that increase serotonin (like certain antidepressants). Symptoms include fast heartbeat, loss of coordination, severe dizziness, severe nausea/vomiting/diarrhea, twitching muscles, unexplained fever, and unusual agitation/restlessness.

Long-Term Effects and Dependency

Stimulants such as Adderall are controlled substances and can be habit-forming. Long-term misuse or taking higher doses than prescribed can lead to dependence. Signs of misuse include needing larger doses to feel the effects or experiencing withdrawal symptoms (such as severe tiredness, sleep problems, and mental/mood changes like depression) when stopping the drug abruptly.

If you have been taking this medication for a long time, do not stop taking it suddenly. Your healthcare professional may want to lower your dose gradually to prevent withdrawal symptoms.

Interactions, Precautions, and Contraindications

Before starting amphetamine-dextroamphetamine, a full review of your medical history is vital. This medication is not suitable for everyone, and certain substances can alter how it works.

Who Should Avoid This Medication

You should typically not take this medication if you have:

• Advanced or severe heart disease.
• Moderate to severe high blood pressure.
• Hyperthyroidism or glaucoma.
• A history of substance misuse.
• Allergic reactions to amphetamine.

Drug Interactions

This medication can interact with a wide range of other substances.

• Monoamine oxidase inhibitors (MAOIs): Taking linezolid, rasagiline, selegiline, or other MAOIs with this medication is dangerous. You need to stop taking MAOIs 14 days before starting Adderall.
• Antidepressants: As mentioned regarding serotonin syndrome, combining stimulants with antidepressants requires careful monitoring.
• Blood Pressure Medications: Since stimulants can raise blood pressure, they may counteract the effects of blood pressure medications.
• Vitamin C and other acidic substances: Acidic substances can reduce the absorption of Adderall, making it less effective.
• Antacids: Antacids like Tums or Rolaids can increase the absorption of Adderall, raising the risk of side effects.

Frequently Asked Questions (FAQ)

Is it okay to take Adderall every day? Yes, if that is how it was prescribed. For conditions like ADHD and narcolepsy, daily usage is common to manage symptoms effectively. However, some healthcare professionals may suggest “drug holidays” (taking a short break from the medication) to assess if the medication is still needed or to manage tolerance. This should only be done under professional guidance.

What is the difference between Adderall and dextroamphetamine? Adderall is a brand name for a mix of two salts: amphetamine and dextroamphetamine. “Dextroamphetamine” refers to just one of those components. While they are both stimulants and work similarly, the mixture in Adderall may affect people differently than dextroamphetamine (Dexedrine).

Will this medication (Adderall) help with anxiety? It depends. For some people, untreated ADHD causes anxiety; treating the ADHD can therefore reduce the anxiety. However, for others, the stimulant nature of the drug can physically mimic anxiety symptoms (increased heart rate, jitters) and make feelings of nervousness worse.

How does the medication (Adderall) feel? When working correctly for ADHD, you shouldn’t feel “high.” Instead, people might report feeling “normal” or “quiet.” The chaos in the brain settles down, allowing you to complete tasks without distraction. If you feel euphoric or overly energetic, the dose may be too high.

Are Adderall and generic amphetamine-dextroamphetamine the same thing? Yes, they are considered to be equally safe and effective. They contain the exact same chemical compounds in the same amounts. However, the “fillers” (inactive ingredients that hold the pill together) may differ, which can very rarely change how the pill affects you.

Can I take Adderall if I don’t have ADHD? It depends. Adderall is also used to treat narcolepsy, and could be used off-label to treat other conditions. As long as you have a valid prescription from a licensed healthcare professional, you can take Adderall. Taking prescription stimulants without a diagnosis and prescription is illegal and dangerous.

What is the closest substitute for Adderall? If Adderall isn’t working or is too expensive, a healthcare professional might suggest an alternative such as methylphenidate (Ritalin/Concerta) or dextroamphetamine (Dexedrine). These are also stimulants, but may have slightly different effects for you.

How to Save on Your Amphetamine-dextroamphetamine Prescription

Here are several practical ways you can save money if you need a prescription for amphetamine-dextroamphetamine — whether you have insurance or not:

• Use a prescription discount card or coupon like Super+ RX: The Super+ RX coupon uncovers discounts to help lower out-of-pocket costs for amphetamine-dextroamphetamine. Whether it’s amphetamine-dextroamphetamine or another medication, we want to help you save—because your well-being comes first.
• Check multiple pharmacies — cash prices can vary. Pharmacies in the same area sometimes charge different prices for the same medication. Comparing cash prices among pharmacies can help you find the cheapest option. Search for your prescription on Super.com/rx, compare prices across pharmacies, and find discounts near you.
• Consider asking for the generic form, not the brand-name form. The generic version of amphetamine-dextroamphetamine is often much cheaper than the brand-name version, Adderall, and works the same. Keep in mind that amphetamine-dextroamphetamine ER and the brand name Adderall XR are extended-release formulations of the medication, so they are not interchangeable with IR amphetamine-dextroamphetamine.

What you can do before you go to the pharmacy:

• Use a discount program like the Super+ RX coupon — print it or bring it on your phone — and ask the pharmacist or cashier to apply it to your prescription.
• Compare at least two or three pharmacies on Super.com/rx to see who offers the lowest price.
• If you are uninsured or if you have a high copay, ask your healthcare team about patient-assistance programs or reduced-cost clinics in your area.

We understand that managing chronic conditions often comes with concerns about the cost of medications. Whether you’re looking for amphetamine-dextroamphetamine 5 mg, amphetamine-dextroamphetamine 10 mg, or another dosage or a brand-name form, a few simple clicks can show you where to get your medication at a more affordable price.
