Unlike other medications, Vyvanse (Lisdexamfetamine) is one of the most prescribed medications for Attention Deficit Disorder (ADD), Hyperactivity Disorder (ADHD) and binge eating disorder (BED). Due to the fact that it has a once-a-day dosing and gentler onset it is preferred by a lot of doctors and patients. But as with all medications it does carry potential side effects.

All You Should Know About This Commonly Prescribed Medication for ADHD

In this article, patients and healthcare professionals will learn about the secondary effects of lisdexamfetamine, the reasons for their occurrence, and what to monitor in the patients.

What Is Lisdexamfetamine?

Lisdexamfetamine is a prodrug of dextroamphetamine which means it becomes effective only after the body metabolizes it. This structure aids in lower potential of misuse and provides long lasting symptom control.

It increases the levels of dopamine and norepinephrine in the brain which is often found to be imbalanced for patients with ADHD.

Common Side Effects: Explained

Loss of Appetite & Weight Loss

  1. This is most common side effect in children and adolescents.
  2. The stimulant effect of Vyvanse leads to suppressed appetite.
  3. Because lisdexamfetamine is commonly prescribed to adolescents and children it is advisable to carefully track their weight over time.

Insomnia

It relates to sleep issues, particularly with some medications taken in the afternoon or evening.

Tip: Following proper sleep hygiene practices and taking medications, if any, in the morning may resolve these issues.

Increased Heart Rate and Blood Pressure

As a stimulant, lisdexamfetamine can cause a mild increase in heart rate and blood pressure.

Who’s at risk: This patients group requires special care when integrated with heart diseases.

Advice: Regular monitoring of heart rate and blood pressure is advised.

Dry Mouth (Xerostomia)

It slowly aggravates the chances of dental cavities and infections of the mouth.

Relief: Drinking sufficient amounts of water and using sugar-free lozenges lessens the symptoms of xerostomia.

Irritability or Mood Swings

For some, this makes them more sensitive to perturbation or emotional hypersensitivity.

Why it matters: It could indicate either over medication or rebound phenomena as the drug effects wane.

What to do: It might be necessary to alter timings or dosages.

Tics or Muscle Twitches

Some individuals are more vulnerable to develop tics or have them worsened by stimulants.

Clinical note: While this does not qualify as a contraindication, it requires observation.

Mental Health Considerations

In some instances, particularly those involving individuals with a psychiatric history, lisdexamfetamine may exacerbate underlying anxiety and mood symptoms. Psychotic symptoms may occur infrequently and primarily with high dosing.

When to Call a Doctor

Although a number of the lisdexamfetamine associated side effects can be managed, patients require immediate medical attention if they experience:

  1. Chest pain
  2. Hallucinations
  3. Uncontrollable aggression
  4. Shortness of breath
  5. Seizures

Balancing Benefits and Risks

From a practical perspective, it is potentially life changing for individuals with ADHD and BED. However, it is important to highlight that lisdexamfetamine does have side effects like other medications. Like with any form of treatment, well-informed use alongside automated safety measures tends to yield the greatest positive results in tandem with two-way communication between patients and healthcare practitioners.

The prescribing clinician’s dosaging should initially start from a baseline and gradually build up towards an optimal clinically relevant dosage considering the patient’s age, pre-existing health conditions, social living circumstances, and other relevant factors.

Closing remarks

The primary treatment prescribed for ADHD is lisdexamfetamine; however, such medications require a physician’s guidance due to their sheer power.
