Treatment of Facial Tics
For facial tics, education and reassurance are sufficient for mild cases, while moderate-to-severe tics should be treated first with clonidine or guanfacine, reserving dopamine receptor blockers like risperidone for severe cases that fail first-line therapy. 1
Initial Assessment and Treatment Decision Algorithm
Before initiating pharmacologic therapy, determine tic severity and impact:
- Mild, infrequent tics that do not interfere with school, work, or daily activities require no medication—education and reassurance alone are sufficient. 1
- Moderate severity tics causing some functional impairment warrant first-line pharmacologic treatment with alpha-2 adrenergic agonists. 1, 2
- Severe, disabling tics that significantly impair function require second-line dopamine receptor blockers. 1, 2
Evaluate for comorbid conditions (ADHD, OCD, anxiety, depression) in all patients, as these occur in >50% of cases and may be more troubling than the tics themselves—treat the most bothersome symptom first. 1, 2
First-Line Pharmacologic Treatment: Alpha-2 Adrenergic Agonists
Clonidine is the preferred initial medication for moderate facial tics:
- Start with 0.05 mg at bedtime. 1
- Increase by 0.05 mg every 4–7 days as needed and tolerated. 1
- Maximum dosage: 0.3–0.4 mg/day divided 3–4 times daily. 1
Guanfacine is an alternative first-line option:
- Start with 0.5 mg at bedtime. 1
- Increase by 0.5 mg every week as needed and tolerated. 1
- Maximum dosage: 3–4 mg/day divided twice daily. 1
These agents have a reasonable safety profile and are particularly beneficial when ADHD coexists with tics. 1, 2
Second-Line Treatment: Dopamine Receptor Blockers
When first-line agents fail or tics are severe, dopamine receptor blockers are the most potent medications available. 1 Efficacy is proportionate to dopamine D2 receptor affinity. 1
Atypical antipsychotics are recommended before typical neuroleptics in most patients due to better tolerability:
Risperidone (first choice among atypical agents):
Aripiprazole is particularly beneficial when significant behavioral issues coexist. 2
Ziprasidone and olanzapine are reasonable alternatives. 1
Typical neuroleptics (haloperidol, pimozide, fluphenazine) are the most potent but commonly cause bothersome side effects—reserve for refractory cases. 1, 2
Non-Pharmacologic Treatment Options
Comprehensive Behavioral Intervention for Tics (CBIT) has emerging evidence of effectiveness:
- Requires a cooperative patient, presence of premonitory urge, and committed family. 2
- Habit reversal is the major component. 2
- Consider as adjunct or alternative to medication in motivated patients. 1, 2
Specialized Interventions for Refractory Cases
Botulinum toxin injections are effective when there are a few particularly disabling motor tics localized to specific facial muscles. 3, 4
Deep brain stimulation has been reported effective for the most severe cases but remains unproven and should only be considered after all other options have failed. 3
Critical Clinical Pitfalls
- Do not withhold treatment based solely on the expectation that tics will improve with age—functional impairment, psychosocial problems, and physical discomfort are clear indications for intervention. 2
- Avoid typical neuroleptics as first-line therapy due to high risk of bothersome side effects including tardive syndromes. 1, 5
- Screen for secondary causes and ensure proper diagnosis before initiating treatment—not all facial movements are primary tic disorders. 3
- Monotherapy is recommended—avoid polypharmacy when possible. 2
