A fourth of individuals in the United States taking prescription stimulants like Adderall reported misusing them in 2025. As many as 9% of people using prescription stimulants met the criteria for a stimulant use disorder.
Amphetamines like Adderall account for the majority of medications prescribed to treat ADHD. This might make Adderall seem safer to take than illicit substances, but misusing prescriptions can be just as devastating as any other substance use.
We’ve seen the impact of excessive Adderall use firsthand at Pacific Sands. It can harm relationships, careers, your health, and every area of life. The side effects of Adderall range from increased focus and insomnia to weight loss and high blood pressure, and Adderall misuse comes with its own physical, psychological, and behavioral symptoms. We’ll cover them all in this blog.
What Is Adderall, and How Does It Affect the Mind and Body?
Adderall is a central nervous system stimulant commonly used to treat ADHD and narcolepsy. Stimulants like Adderall increase your norepinephrine and dopamine levels – chemical messengers known as neurotransmitters. Norepinephrine contributes to focus, reaction time, and your “fight or flight” response. Dopamine is associated with motivation and your brain’s reward system.
When you consider this, it makes sense why Adderall would help individuals with ADHD: they have trouble regulating attention and initiating tasks.
Unfortunately, these effects can be appealing to people without ADHD, too. Adderall typically makes people more alert, better at concentrating, and can even suppress appetite. Adderall is most associated with students who take it to perform better in school and study more successfully, but some business professionals misuse it to boost their energy levels, too. Even athletes might misuse Adderall, believing it increases their performance in their sport of choice.
Adderall use disorder isn’t just limited to these demographics. Adderall can cause euphoria when taken in high enough doses, thanks to its influence on the parts of the brain related to pleasure. That feeling can be tempting to chase for anyone, especially individuals looking to escape from psychological pain.
Adderall Side Effects Over Time: From the Beginning to Long-Term
It’s important to note that taking Adderall isn’t inherently bad. It can be a helpful prescription for many people with ADHD and narcolepsy. However, it does have side effects, no matter what reason you take it. Some, you might feel right away. Others occur after using Adderall for a longer period of time. People with Adderall use disorder typically fall into the latter category. See our chart below for more information.
Common Short-Term Side Effects of Adderall Use
The side effects you might experience when taking Adderall depend on the dosage. Higher doses are associated with a greater risk of side effects.
Side effects of short-term Adderall use can include:
- Restlessness
- Trouble sleeping
- Constipation
- Headaches
- Sexual dysfunction
- Hallucinations
- Paranoia
- Worsening symptoms of other mental health conditions
Keep in mind that everyone’s experience with Adderall will be different. That means someone might have all of these symptoms, symptoms outside of this list, no symptoms at all, or anything in between. Unfortunately, it’s hard to predict how Adderall will affect you before you take it.
Long-Term Side Effects of Adderall Use
Adderall is generally safe to take long-term, so long as you’re following your doctor’s directions. Any Adderall use without the approval of a doctor is significantly more likely to harm your health, especially at higher doses.
The following effects are sometimes associated with Adderall long-term:
- Heart complications, especially in those with existing heart problems. Adderall can increase heart rate and blood pressure, which puts stress on the heart long-term.
- New or worsened mental health symptoms, such as psychosis, mania, or aggression, especially in children.
- Slower growth in children, causing a shorter height over time.
- Changes in sexual function, ranging from lower sex drive to longer-lasting erections.
- Tolerance, requiring higher doses of Adderall to achieve the same effect.
- A physical dependence, causing withdrawal symptoms after Adderall wears off.
Consider the impact of managing any short-term side effects you experience with Adderall over time, too. For example, if Adderall causes constipation, fewer bowel movements can cause additional digestive complications. Consistent restlessness and insomnia can deprive your body of the rest it needs to recover and function at its best every day. Any depression experienced after an Adderall “crash” can wear on someone long-term.
If you take Adderall long-term, you may develop a tolerance and require higher doses of the medication to feel the same as you did when you first started taking it. The higher the dose you take, the more likely you are to experience adverse effects, too.
Physical dependence occurs when someone’s brain becomes so used to a substance that it doesn’t function properly without it. This can happen with Adderall, whether you’re taking it as prescribed or not. A physical dependence is not the same as an Adderall use disorder, but they often go hand-in-hand. If you have a physical dependence on Adderall, you’ll experience painful withdrawal symptoms until you take another dose. This creates a vicious cycle – especially for people with an Adderall use disorder.
If you were prescribed Adderall and experience withdrawal or any other symptoms mentioned here, make sure to talk to your doctor. A medical professional will have advice tailored to your unique situation and medical history, which is always important when dealing with medication.
Adderall Misuse and the Risk of an Overdose
If you were prescribed Adderall and take it according to your doctor’s directions, Adderall is perfectly safe. The risk increases when you use Adderall outside of a doctor’s discretion, whether your Adderall was prescribed to you or not.
Overdose is more common at higher doses, but it’s possible at any dose, because Adderall impacts everyone differently. An Adderall overdose is significantly more likely if you use it in combination with other substances, especially opioids.
Symptoms of Adderall overdose may include:
- Confusion
- Paranoia
- Hallucinations
- High body temperature
- Faster breathing and heartbeat
- Very high blood pressure
- Chest pain
- Nausea and vomiting
- Seizures
When Adderall causes an overdose or other severe health complication, it’s typically heart-related, so keep an eye out for any other cardiovascular symptoms. If you suspect you or someone you know is experiencing an Adderall overdose, get medical help right away. It’s common to worry about legal repercussions for anyone misusing Adderall, but California’s Good Samaritan Law protects anyone offering help during an emergency, including an overdose.
How to Know if You or a Loved One Needs Help for an Adderall Use Disorder
Medical professionals use the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) to officially diagnose stimulant use disorders like Adderall addiction. You can look at the criteria yourself and see if it applies to you or your loved one. If it does, it’s a good idea to seek treatment.
There are additional signs of an Adderall use disorder that the DSM-5 doesn’t cover, too, and these might be more noticeable if you’re concerned about a loved one. Our chart below covers the behavioral, physical, and psychological signs of Adderall use disorder, and the DSM-5 criteria.
