Lisdexamfetamine 10mg Capsules
Overview
What is this medicine?
How to Use This Medicine
To get the most benefit from your medication, follow your doctor's instructions carefully. Read all the information provided with your prescription and follow the instructions closely. Take your medication at the same time every day, with or without food. To minimize the risk of sleep disturbances, avoid taking your medication late in the day.
When taking your medication, swallow the capsule whole without chewing, breaking, or crushing it. However, if you need to, you can open the capsule and mix the powder with water, orange juice, or yogurt. If the powder clumps together, you can use a spoon to gently break it apart. Mix the powder well and swallow the mixture immediately. Do not store the mixed medication for later use.
Storing and Disposing of Your Medication
Store your medication at room temperature, protected from light and moisture. Keep it in a dry place, away from the bathroom. To ensure safety, store your medication in a secure location where children and pets cannot access it, and where others cannot easily find it. Consider using a locked box or area to store your medication.
When disposing of your medication, do not flush it down the toilet or pour it down the drain unless instructed to do so by your pharmacist. Instead, check with your pharmacist for guidance on the best way to dispose of unused or expired medication. You may also want to explore local drug take-back programs.
What to Do If You Miss a Dose
If you miss a dose, take it as soon as you remember. However, if it's close to the time for your next scheduled dose, skip the missed dose and resume your regular dosing schedule. Do not take two doses at the same time or take extra doses to make up for the missed one.
Lifestyle & Tips
- Take exactly as prescribed, usually once daily in the morning. Taking it in the afternoon or evening may cause sleep problems.

Caution with Daily Activities
Until you know how this medication affects you, avoid driving and engaging in activities that require alertness or clear vision.
Tolerance and Dependence
Long-term or high-dose use of this medication can lead to tolerance, where the drug may not work as well, and you may need higher doses to achieve the same effect. If you experience a decrease in the medication's effectiveness, contact your doctor. Do not take more than the prescribed dose. Additionally, regular use of this medication can cause dependence, and suddenly stopping it may lead to withdrawal symptoms. Consult your doctor before reducing the dose or stopping the medication, and follow their instructions carefully.
Heart-Related Precautions

This medication may cause high blood pressure, so it is crucial to follow your doctor's instructions for monitoring your blood pressure and heart rate.
Interactions with Other Medications and Lab Tests
Inform all your healthcare providers and lab workers that you are taking this medication, as it may affect certain lab tests. Before using over-the-counter (OTC) products that may increase blood pressure, such as cough or cold medications, diet pills, stimulants, non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen, or certain natural products or aids, consult your doctor.

Drug Interactions
Contraindicated Interactions
- Monoamine Oxidase Inhibitors (MAOIs) - concurrent use or within 14 days of MAOI use (risk of hypertensive crisis, serotonin syndrome)
Major Interactions
- Serotonergic drugs (e.g., SSRIs, SNRIs, TCAs, triptans, fentanyl, lithium, tramadol, St. John's Wort) - risk of serotonin syndrome
- Alkalinizing agents (e.g., sodium bicarbonate, acetazolamide, some antacids) - increase plasma levels and prolong half-life of dextroamphetamine
- Acidifying agents (e.g., ascorbic acid, ammonium chloride, fruit juices) - decrease plasma levels and shorten half-life of dextroamphetamine
- Antihypertensives - may reduce the hypotensive effect of these drugs
Moderate Interactions
- Tricyclic Antidepressants (TCAs) - increased cardiovascular effects of amphetamines
- Antipsychotics (e.g., phenothiazines, haloperidol) - may antagonize the stimulant effects of amphetamines
- Alcohol - may increase risk of adverse cardiovascular events
Minor Interactions
- Not available
Monitoring
Baseline Monitoring
Rationale: CNS stimulants can cause increases in BP and HR.
Timing: Prior to initiation of therapy.
Rationale: Monitor for growth suppression in pediatric patients.
Timing: Prior to initiation of therapy.
Rationale: Stimulants can exacerbate pre-existing psychiatric conditions or induce new psychotic/manic symptoms.
Timing: Prior to initiation of therapy.
Rationale: Risk of sudden death in patients with pre-existing serious structural cardiac abnormalities or other serious heart problems.
Timing: Prior to initiation of therapy; consider ECG if indicated.
Routine Monitoring
Frequency: Regularly (e.g., at each visit or every 3-6 months)
Target: Within normal limits for age/individual
Action Threshold: Persistent elevation requiring intervention or discontinuation.
Frequency: Regularly (e.g., every 3-6 months for children, annually for adults)
Target: Normal growth trajectory for children; stable weight for adults
Action Threshold: Significant growth deceleration or weight loss.
Frequency: At each visit
Target: Absence of new or worsening symptoms
Action Threshold: Emergence or worsening of symptoms requiring dose adjustment or discontinuation.
Frequency: At each visit

Action Threshold: Lack of efficacy or intolerable side effects.
Symptom Monitoring

Special Patient Groups
Pregnancy
Use during pregnancy should be considered only if the potential benefit justifies the potential risk to the fetus. Amphetamines may cause adverse pregnancy outcomes, including premature delivery and low birth weight. Neonates exposed to amphetamines during pregnancy may experience withdrawal symptoms.
Trimester-Specific Risks:
Lactation
Dextroamphetamine is excreted into human milk. Breastfeeding is not recommended during treatment with lisdexamfetamine due to the potential for serious adverse reactions in the breastfed infant (e.g., irritability, poor feeding, sleep disturbances, weight loss). If breastfeeding is chosen, monitor the infant closely.
Pediatric Use
Approved for ADHD in children 6 years and older. Monitor growth (height and weight) carefully, as stimulants can cause growth suppression. Monitor for emergence or worsening of psychiatric symptoms.
Geriatric Use
Clinical studies did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Clinical Information
Clinical Pearls
- Lisdexamfetamine is a prodrug that requires enzymatic hydrolysis in the blood to become active dextroamphetamine, which contributes to its smoother, longer-lasting effect and potentially lower abuse liability compared to immediate-release amphetamines.
- The 10mg capsule strength is typically used for dose titration or for patients who require a very low maintenance dose, rather than as a standard starting dose.
- Patients should be advised to take the medication in the morning to avoid sleep disturbances.
- The medication can be taken with or without food. The capsule can be swallowed whole, or opened and the entire contents mixed with water, yogurt, or orange juice and consumed immediately.
- Careful cardiovascular and psychiatric screening is essential before initiating therapy and throughout treatment.
Alternative Therapies
- Other CNS Stimulants (e.g., Methylphenidate, Mixed Amphetamine Salts, Dextroamphetamine)
- Non-stimulants (e.g., Atomoxetine, Guanfacine extended-release, Clonidine extended-release)
- Behavioral therapy (for ADHD)
- Cognitive Behavioral Therapy (CBT) (for BED)
