There is no single “best” medication for tics. The right choice depends on how severe the tics are, what other conditions are present (especially ADHD), and how well someone tolerates side effects. Current guidelines from the American Academy of Neurology actually recommend behavioral therapy as a first-line treatment before medication, and for mild tics that aren’t causing problems, watchful waiting is considered perfectly acceptable.
That said, when tics are frequent or disruptive enough to need medication, there’s a clear hierarchy most clinicians follow. Here’s how the options compare.
Behavioral Therapy Comes First
Before reaching for a prescription, the American Academy of Neurology recommends a structured approach called Comprehensive Behavioral Intervention for Tics (CBIT). This is a form of therapy where you learn to recognize the urge that precedes a tic and practice a competing response, essentially training your brain to redirect the impulse. Guidelines specifically state that clinicians should offer CBIT before medication when it’s available. It works well enough that multiple medication classes and behavioral therapy must all be tried or ruled out before more invasive treatments like deep brain stimulation are even considered.
Alpha-2 Agonists: The Usual Starting Point
When medication is needed, most clinicians start with alpha-2 adrenergic agonists, specifically clonidine and guanfacine. These drugs were originally developed for blood pressure but have a calming effect on the neural circuits involved in tics. The AAN gives them a strong recommendation (Level B), meaning there’s moderate confidence they work.
These medications are especially useful when tics and ADHD occur together, which happens frequently. Both clonidine and guanfacine can improve attention and reduce tics simultaneously, making them a practical two-for-one option. The trade-off is that they tend to cause drowsiness, particularly clonidine, and their tic-reducing effect is generally more modest than what antipsychotics can achieve. They’re favored as a starting point because their side effect profile is far gentler.
Antipsychotics: Strongest Evidence, More Risk
Only three medications carry formal FDA approval for suppressing tics in Tourette syndrome: haloperidol, pimozide, and aripiprazole. Of these, aripiprazole has become the most widely used because it’s effective and better tolerated than the older two.
In a randomized, placebo-controlled trial, aripiprazole reduced tic severity scores by 56% over eight weeks, compared to 39% with placebo. About 86% of patients on aripiprazole showed meaningful improvement, versus 57% on placebo. A systematic review found even higher overall response rates: roughly 89% for aripiprazole, compared to 69% for clonidine and 63% for risperidone. The typical effective dose for tics is around 5 to 10 mg per day, which is lower than what’s used for other psychiatric conditions.
Haloperidol and pimozide are older antipsychotics that effectively suppress tics but carry a heavier burden of side effects, including muscle stiffness, restlessness, and a risk of involuntary movements with long-term use. Haloperidol is approved for children as young as 3, pimozide for ages 12 and up, and aripiprazole for ages 6 and up.
Risperidone, though not FDA-approved specifically for tics, is another antipsychotic commonly used off-label. Head-to-head studies suggest it works about as well as aripiprazole, though response rates in broader reviews are somewhat lower.
Metabolic Monitoring With Antipsychotics
All antipsychotics require metabolic monitoring because they can affect weight, blood sugar, and cholesterol. Aripiprazole and haloperidol are considered low risk for metabolic problems compared to other antipsychotics. Risperidone falls in the medium-risk category. Regardless of which one is prescribed, guidelines recommend checking weight, blood sugar, cholesterol, and blood pressure at baseline, then at regular intervals over the first year: roughly at one month, two months, three months, six months, and annually after that. Weight ideally gets checked even more often in the early weeks.
Topiramate: A Useful Alternative
Topiramate, an anti-seizure medication, has earned a surprisingly strong recommendation (Level B) from the AAN for tic treatment. It’s positioned as an alternative when alpha-2 agonists haven’t worked well enough or cause too many side effects. The mechanism isn’t entirely clear, but it seems to dampen overactive neural signaling involved in tic generation. Side effects can include mental fogginess, tingling in the hands or feet, dizziness, and headache, which limits its use in some people. Still, for those who want to avoid antipsychotics, it offers a meaningfully different approach.
Other Options Worth Knowing About
Baclofen, a muscle relaxant, has shown some promise in small studies. In a trial of children with Tourette syndrome, four weeks of baclofen improved overall functioning scores compared to placebo, though the reduction in tic severity itself only approached statistical significance. The benefit seemed to come more from reducing the distress and impairment associated with tics than from eliminating the tics outright. It’s not a first-line choice, but it may help selected patients.
Botulinum toxin injections are used for specific, bothersome motor tics that are concentrated in one area. The most commonly treated tics include eye blinking, head turning, and shoulder shrugging. Injections are typically repeated every three months, and in one registry study, patients continued treatment for an average of about 40 months, suggesting it provides sustained benefit for those who respond. This approach doesn’t help with generalized tics or vocal tics (no patients in the registry received injections for vocal tics).
Cannabis-based medications have a limited recommendation from the AAN, reserved only for adults with treatment-resistant tics who have already tried multiple medication classes and behavioral therapy without adequate relief. The evidence base is thin, and this option is restricted by regional legislation.
What About ADHD Medications and Tics?
If you or your child has both ADHD and tics, you may have heard that stimulant medications make tics worse. This is largely a myth that persists from older case reports. Large controlled studies tell a different story. In one year-long trial, new tics appeared in about 24% of children taking methylphenidate, but also in 22% of children on placebo, meaning the drug wasn’t the cause. Another study of 136 children with both Tourette syndrome and ADHD found that tics actually improved on methylphenidate, and the chance of tics worsening was identical (33%) whether kids took the medication or a sugar pill.
An even larger observational study found that new tic disorders were less common in children treated with stimulants, and tics that did occur resolved sooner. The amphetamine class of stimulants (like mixed amphetamine salts) hasn’t been studied as carefully for this question, and there’s some evidence that children with tics tolerate methylphenidate better than amphetamines.
That said, clonidine, guanfacine, and atomoxetine all treat ADHD without any concern about tic worsening, so many clinicians start there when both conditions are present. If those aren’t effective enough for the ADHD symptoms, methylphenidate remains a reasonable option without significant risk of making tics worse.
How Medications Are Typically Chosen
The practical sequence most clinicians follow looks like this:
- Mild tics without impairment: watchful waiting or CBIT alone
- Tics causing functional problems: CBIT first if available, then alpha-2 agonists (especially if ADHD is also present)
- Tics not responding to first-line treatment: aripiprazole or another antipsychotic, or topiramate as an alternative
- Localized, bothersome motor tics: botulinum toxin injections targeting the specific muscles involved
- Treatment-resistant tics in adults: cannabis-based medication may be considered where legal
No medication eliminates tics completely in most people. The realistic goal is reducing tic frequency and intensity enough that they stop interfering with daily life. Tics also tend to fluctuate naturally, peaking in late childhood and often improving substantially by early adulthood, which means the need for medication may change over time.
