Dextroamphetamine is used for the treatment of attention deficit-hyperactivity disorder (ADHD). It can also be used to treat uncontrollable daytime sleepiness (narcolepsy). Some side effects of the medication include difficulty sleeping, restlessness, and loss of appetite (that might lead to possible weight loss).
Attention deficit-hyperactivity disorder (ADHD)
Narcolepsy (extreme daytime sleepiness)
Dextroamphetamine is a stimulant medication. It's not exactly known how dextroamphetamine helps to improve attention and focus. But it's thought to work by raising the levels of chemicals in your brain called norepinephrine, dopamine, and serotonin.
Dextroamphetamine can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: History of substance or alcohol use disorder | Taking more dextroamphetamine than prescribed | Long-term use | Suddenly stopping dextroamphetamine
Dextroamphetamine has a risk of misuse and dependence. Misuse is when a medication is used differently than how it's prescribed. Misusing dextroamphetamine raises your risk for serious and sometimes life-threatening side effects, such as high heart rate, high blood pressure, other heart problems, and changes in behavior. In addition, over time, you can become physically dependent on dextroamphetamine to function normally. And if you develop dependence, you might have bothersome withdrawal symptoms if you stop taking the medication suddenly after you've taken it for a long time. These symptoms include irritability, nightmares, and sleep problems. Because of these risks, it's important to take dextroamphetamine exactly as prescribed to you. Don't change the dose or how often you take it without talking to your provider first.
Risk factors: History of heart problems
There have been reports of sudden death, stroke, and heart attack in people with heart problems who took dextroamphetamine at usual doses. Dextroamphetamine can also raise your blood pressure and heart rate. Tell your healthcare provider if you have a history of heart problems before starting dextroamphetamine to make sure it's safe for you to take. Your provider will check for heart problems before starting treatment. Let your provider know if you experience unexplained fainting, chest pain with physical activity, or irregular heartbeat while you're taking dextroamphetamine.
Risk factors: History of psychotic episodes, bipolar disorder, or other mental health or mood-related conditions
Some people who've taken a stimulant like dextroamphetamine can have mental health problems, such as hallucinations (seeing things that aren't really there), aggressive behavior, unclear thinking, and mania. This medication can worsen mood-related problems that you already have, but these changes in behavior can also happen even if you haven't had these problems before. If you develop these mood-related symptoms while taking dextroamphetamine, talk to your healthcare provider right away because you might have to stop taking it.
In studies, children taking a similar stimulant medication for ADHD had a slowed growth rate (both in height and weight). It's not clear if dextroamphetamine can cause something similar to happen to your child. To be safe, your child's healthcare provider will check your child's growth progress closely. If they suspect slowed growth, they might pause or stop your child's dextroamphetamine treatment. Talk to your child's provider if you have any concerns.
Risk factors: History of seizures | High risk of seizures
Although rare, dextroamphetamine might make it easier for you to have seizures, especially if you've had seizures before. If a seizure happens while you're taking this medication, get medical help right away. You'll likely have to stop taking dextroamphetamine.
Using dextroamphetamine for ADHD might be linked to blood circulation problems, such as Raynaud's phenomenon, which can lower blood flow to your fingers and toes. This problem can cause your fingers or toes to change from a pale or blue to a red color and feel cold, numb, or painful. If this happens, it's usually mild and happens occasionally. But rarely, it can cause sores to form and damage your tissue. Let your healthcare provider know if you experience any of these symptoms. Usually, they get better when the dextroamphetamine dose is lowered or the medication is stopped.
Risk factors: Taking monoamine oxidase inhibitors (MAOI) 14 days before starting dextroamphetamine | Taking other medications that raise serotonin levels in your brain
Serotonin syndrome is a rare, but potentially life-threatening condition where there's too much serotonin in the brain. Serotonin is one of the chemicals in your brain responsible for your mood. Since dextroamphetamine might raise your serotonin levels in the brain, your risk for this condition goes up if you use dextroamphetamine with other medications that also affect serotonin levels. These medications can include antidepressants (e.g., sertraline (Zoloft), duloxetine (Cymbalta)), MAOIs (e.g., phenelzine (Nardil)), and certain migraine medications (e.g., sumatriptan (Imitrex)). Symptoms of serotonin syndrome include fast heart rate, sweating, muscle stiffness or spasms, high fever, changes in behavior, and confusion. Get medical help right away if you have any of these symptoms.
Dextroamphetamine can interact with a lot of commonly used medications. Dextroamphetamine counteracts (works against) the effects of many blood pressure medications, including prazosin (Minipress) and beta-blockers like propranolol (Inderal) and metoprolol (Lopressor). This means that the blood pressure medications might not work as well for you if you take them at the same time as dextroamphetamine.
Additionally, avoid taking dextroamphetamine with other medications that affect serotonin levels to lower the risk of serotonin syndrome. Also don't take dextroamphetamine with monoamine oxidase inhibitors (MAOIs) because of the risk of severely high blood pressure and serotonin syndrome. Make sure your healthcare provider and pharmacist know about all the medications you take (including over-the-counter medications and supplements) so they can check for any dangerous interactions. Don't start any new medications while taking dextroamphetamine without letting them know.

Has a risk of misuse and dependency
A controlled medication, so there are special requirements for getting the prescription filled
Can cause trouble sleeping if taken late in the day
Not the best option if you have heart problems
Avoid taking dextroamphetamine too late in the day. Otherwise, the medication can make it difficult for you to sleep at night.
Take dextroamphetamine with or without food. It's best to take it in the same way each day so the medication gets absorbed into your body consistently. Don't eat or drink too many acidic things (e.g., fruit juice, citrus fruits) because they can affect medication absorption into the body.
Avoid alcohol while taking dextroamphetamine because it can make your ADHD symptoms worse and make your medication work less well. This combination can also cause dangerous side effects, including alcohol poisoning and heart problems.
Avoid driving the first few days after you start dextroamphetamine and after dose changes until you know how this medication affects you. Dextroamphetamine might cause dizziness. It might also cause blurry vision, which can affect how well you see.
Stimulants like dextroamphetamine can lower appetite, which can potentially lead to some weight loss. If your child is taking dextroamphetamine, the medication might also affect their growth. Make sure to follow a healthy and balanced diet. If you notice that you're not eating enough or you're losing too much weight while taking dextroamphetamine, let a provider know.
Dextroamphetamine might worsen tics and Tourette syndrome. Talk to a provider if you have these problems so they can see if this medication is right for you.
Dextroamphetamine can interact with several medications. Make sure your provider knows all the medications you're taking before starting dextroamphetamine. Don't start any new medications while taking dextroamphetamine without talking to your provider or pharmacist first.
Take dextroamphetamine exactly as your provider told you to. Don't change your dose or suddenly stop taking the medication without talking to your provider first. Doing so can lead to bothersome withdrawal symptoms, such as tiredness, irritability, and trouble sleeping. If you want to stop dextroamphetamine, speak with your provider about how to do so safely.
For the dextroamphetamine extended-release capsules: Don't cut, crush, or chew the capsule because it'll affect how it releases medication into your body. Each extended-release capsule is specially made so that some medication is released into the body right away, while the rest gets slowly released throughout the day.
For the dextroamphetamine oral liquid: Make sure you know how much medication you need to measure out and take. Only use an oral syringe or dosing cup from the pharmacy to measure out your dose. Don't use household spoons because they aren't accurate and might cause you to take the wrong dose. Store the dextroamphetamine oral liquid at room temperature in the bottle you got from the pharmacy to protect it from light.
