Treatment-resistant depression (ICD-10: F32.x, F33.x): Adjunct for augmentation in select cases

Administration: Once daily in the morning with or without food; high-fat meals may delay Tmax and increase exposure; do not crush/chew capsules; if unable to swallow, sprinkle entire contents on ≤1 tablespoon applesauce and swallow immediately
Missed Dose: Take next dose as scheduled; do not double dose
Discontinuation/Tapering: May discontinue abruptly after short-term use; taper if long-term (>4 weeks) or high-dose to minimize rebound symptoms

Common:
- Appetite/weight loss
- Insomnia, headache
- Abdominal pain, nausea, dry mouth
- Increased heart rate/blood pressure, anxiety/irritability
Serious:
- Black box warning: Drug abuse/dependence; assess risk prior to use
- Cardiovascular: Sudden death/myocardial infarction in patients with cardiac disease, priapism
- Psychiatric: Psychosis, mania, aggression, suicidal ideation
- Peripheral vasculopathy (e.g., Raynaud's): Digital ulceration
- Hypersensitivity: Rash, anaphylaxis

When to Call the Doctor:
- Severe mood changes, aggression, or suicidal thoughts.
- Chest pain, rapid heartbeat, shortness of breath (cardiovascular concerns).
- Uncontrolled movements, tics, or worsening anxiety.
- Numbness, coldness, or color changes in fingers or toes (circulatory issues).
- Unexplained weight loss or delayed growth in pediatric patients.
Safety Tips:
- Monitor blood pressure and heart rate, especially in patients with cardiovascular risk.
- Use caution in patients with anxiety, bipolar disorder, or psychosis, as symptoms may worsen.
- Avoid caffeine and other stimulants, which may amplify side effects.
- Ensure adequate hydration and nutrition, as appetite suppression is common.
- Tapering may be required if discontinuing after long-term use.
Parent Tips for Pediatric Patients:
- Encourage a nutrient-dense diet to counteract appetite suppression.
- Administer in the morning before school for optimal effect.
- Monitor school performance and behavioral changes.
- Observe for sleep disturbances; adjust timing if necessary.
- Communicate regularly with teachers and caregivers about medication effects.

- Glaucoma, severe hypertension, symptomatic cardiac disease
Pregnancy: Category C (older); limited human data—use if benefit outweighs risk; neonatal withdrawal possible
Lactation: Present in breast milk; weigh risks (irritability, reduced weight gain in infant)
Drug Interactions:
- MAOIs/serotonergics: Hypertensive crisis/serotonin syndrome
- CYP2D6 inhibitors (e.g., bupropion): Increased methylphenidate levels
- Acidifiers (e.g., vitamin C): Decreased absorption; alkalinizers (e.g., antacids): Increased absorption
- Pressors (e.g., alpha-agonists): Potentiated hypertension
