Q

Treatment for ADHD, side effects?

A

CNS stimulants (eg, methylphenidate, dextroamphetamine, amphetamine salts [dextroamphetamine and amphetamine combo]). ■ Adverse effects: Weight loss (↓ appetite), insomnia, anxiety, irritability, headache, tic exacerbation, and ↓ growth velocity (normalizes when medication is stopped). ■ Alternatives: Nonstimulants. ■ Atomoxetine (norepinephrine reuptake inhibitor): Can be tried first because of the negative side-effect profile of CNS stimulants.

Q

Treatment for Tourette syndrome

A

Antidopaminergic agents: ■ Dopamine-depleting agents (eg, tetrabenazine [VMAT-2 inhibitor; results in ↓ uptake of monoamines]): Preferred over dopamineblocking agents; does not cause tardive dyskinesia (TD). ■ Dopamine-blocking agents: Antipsychotics (eg, fluphenazine, risperidone, haloperidol, pimozide). ■ Severe, refractory tics: Treat with haloperidol or pimozide (typical antipsychotics). ■ α2-agonists (eg, clonidine, guanfacine): Less effective at tic reduction; more favorable side-effect profile.

Q

Treatment for schizophrenia

A

■ Antipsychotics (see Table 2.14-2); long-term follow-up. ■ Supportive psychotherapy, training in social skills, vocational rehabilitation, and illness education may help. ■ Negative symptoms may be more difficult to treat than positive symptoms; atypical antipsychotics are the drug of choice.
