The Side Effects of Adderall

What you need to know before taking Adderall for ADD or ADHD.

Adderall is an amphetamine that is mainly prescribed to treat the symptoms of ADHD, but it can also be used to treat depression and narcolepsy. Adderall is a Schedule II controlled substance, meaning it has a high potential for abuse and dependence. Despite this, it is one of the most commonly prescribed medications in the United States.

How Adderall Works

Adderall works by increasing the availability of dopamine and norepinephrine in the brain. These neurotransmitters play a key role in attention, focus, and impulse control — the very functions that are impaired in people with ADHD. By boosting these chemicals, Adderall helps the ADHD brain function more like a neurotypical brain.

Common Side Effects of Adderall

Like all medications, Adderall can cause side effects. The most common include:

  • Decreased appetite: One of the most common side effects, particularly in children. This can lead to weight loss and growth concerns with long-term use.
  • Insomnia: Adderall is a stimulant and can make it difficult to fall asleep, especially if taken too late in the day.
  • Increased heart rate and blood pressure: Adderall stimulates the cardiovascular system, which can be a concern for people with pre-existing heart conditions.
  • Dry mouth: A very common side effect that can usually be managed by staying well-hydrated.
  • Headaches: Some people experience headaches, particularly when the medication is wearing off.
  • Irritability or mood changes: Some people feel irritable, anxious, or emotionally flat while on Adderall, particularly as it wears off ("rebound" effect).
  • Stomach upset: Nausea, stomach pain, and digestive issues are common, especially when taking Adderall on an empty stomach.

Serious Side Effects

More serious side effects are less common but require immediate medical attention:

  • Chest pain or irregular heartbeat
  • Shortness of breath
  • Hallucinations or psychosis
  • Severe anxiety or panic attacks
  • Signs of circulation problems (numbness, pain, or color changes in fingers or toes)

Adderall and Dependency

Because Adderall is a stimulant with abuse potential, physical and psychological dependence can develop with prolonged use, particularly at higher doses. Tolerance — needing more medication to achieve the same effect — can also develop over time. It is important to take Adderall exactly as prescribed and to discuss any concerns about dependency with your prescribing physician.

Alternatives to Adderall

If Adderall's side effects are problematic, there are several alternatives worth discussing with your doctor:

  • Vyvanse — a prodrug that is converted to active amphetamine in the body, often with a smoother onset and offset
  • Concerta (methylphenidate) — a different class of stimulant
  • Ritalin — another methylphenidate formulation
  • Non-stimulant options such as Strattera (atomoxetine) or Intuniv (guanfacine)
