BBW warnings for stimulants:
- heart-related problems: increased BP and HR, stroke and heart attack in adults, sudden death in those who have existing heart problems/defects
- psychiatric problems: new or worse behavior and thought problems, bipolar illness, aggressive behavior or hostility
- Children and teens: new psychotic symptoms (hearing voices, believing this that are not real, suspicious)
Stimulants possible MoA
inhibit norepi and dopamine reuptake
Contraindications to stimulants use
glaucoma, history of tics, current MAOI use
Monitoring for stimulants
BP & HR (at least monthly), height/weight of children, symptom improvement, mood changes/worsening
Side effects of stimulants: GI, Eye, CV, Mood, etc
- nausea, loss of appetite (lose wt, anorexia), insomnia, dizzy, HA, lightheaded (if child faints, SOB, chest pain - call doctor), irritable, blurry vision, difficulty with visual accomodation
- Increase BP 2-4 mmHg, HR 3-8 bpm - monitor, caution in CV disease
- Worsening of mixed/mania episodes if bipolar disorder
- Withdrawal symptoms (hyper): must titrate UP and DOWN
- Risk of seizures - caution in seizure history
What is unique about lisdexamfetamine?
Prodrug. Needs first pass metabolism to dextroamphetamine. Thus, may have decreased risk of abuse because cannot be injected or snorted
If Vyvanse caps are too big to swallow, what can be done?

What is the indication for generic guanfacine? Brand name?
hypertension; Tenex
Strattera MoA
selective NE reuptake inhibitor
Intuniv SEs
guanfacine:
overall well-tolerated
somnolence, hypoTN, bradycardia, HA, fatigue, upper GI pain, nausea, increase lethargy, fainting
Intuniv DDI
3A4 substrate; avoid use with 3A4 inducers/inhibitors
Is Intuniv ok with food?
As long not taken with high-fat meal (will increase absorption)
Kapvay SEs
clonidine extended-rel:
somnolence (higher incidence than Intuniv), bradycardia, dry mouth, fatigue, lethargy, depression, psychotic reactions, nasal stuffiness, impotence, exacerbate Parkinson’s,
(IMP) rebound HTN (with sweating, anxiety, tremors) if stopped abruptly - do not become dehydrated
XR formulation supposed to have less SEs
MoA of Intuniv and Kapvay
central acting alpha2 adrenergic R agonists -> decrease sympathetic outflow from CNS -> decrease BP, HR, peripheral resistance
unknown MoA in ADHD
Provigil and Nuvigil require MedGuide due to..
risk of severe rash incl SJS/TEN (this is why Provigil was denied for use in ADHD in children). Stop use if rash occurs.
Provigil and Nuvigil SEs
