There are several kinds of medication than can help kids with Tourette’s or another tic disorder. But it’s important to note that not all kids who develop tics need treatment. Tics are very common. They often go away on their own, and they tend to bother parents more than they do the children experiencing them. Drawing attention to them can make them worse. So doing nothing can be the best strategy — at least initially.
Treatment comes into play if tics are upsetting your child, giving them pain, or making it hard for them to function in everyday life — say they’re disrupting class or getting bullied because of their tics.
The first recommended step in treatment is a specialized form of therapy called comprehensive behavioral intervention for tics (CBIT). CBIT is centered on habit reversal training, in which the child learns to recognize when they have an urge to tic and substitute a competing response — an easier, more comfortable, or less noticeable action or behavior that makes the tic impossible. For instance, if a child’s tic is jerking their head to the side, the strategy might be to put their chin down instead.
But if therapy isn’t effective in reducing a child’s tics, medication can help.
Guanfacine and clonidine for tics
First-line medications for Tourette’s and other tic disorders are a class of drugs called alpha-2 agonists, explains Paul Mitrani, MD, PhD, a child and adolescent psychiatrist at the Child Mind Institute. Alpha agonists decrease the release of a neurotransmitter called norepinephrine, which stimulates the nervous system. Alpha agonists serve as a kind of dimmer switch — by calming down the system, they make the urge to tic less frequent, less intense, and by extension, easier to control.
The two alpha-2 agonists usually prescribed for tics are guanfacine and clonidine. Dr. Mitrani reports that he usually starts by prescribing guanfacine because it comes in a longer-acting form (Intuniv), which reduces symptoms for a full 24 hours. Clonidine’s long-acting form (Kapvay) is effective for 12 hours.
Dr. Mitrani adds that there is a new liquid form of clonidine called Onyda XR that lasts 24 hours, but there isn’t yet a strong body of evidence regarding its effectiveness for tics. Onyda XR is FDA-approved for ADHD, as are Kapvay and Intuniv.
While no alpha agonist medications are FDA-approved specifically for tics, Kapvay and Intuniv are frequently used off-label for them. There is ample research on their effectiveness for tics, and they are recommended by clinical practice guidelines.
Some children respond better to several doses of short-acting guanfacine or clonidine, Dr. Mitrani notes, rather than a smoother dose of a long-acting medication. This may be because medication can be timed to peak at times when kids need tic suppression most, such as at school.
Alpha agonists are the preferred first line medications for tic disorders because their side-effects, including drowsiness and low blood pressure, are relatively mild.
Antipsychotics for tics
If alpha agonists aren’t helping, the next step would be to try an antipsychotic medication, which can be more effective for treating tics, Dr. Mitrani notes, but their side effects are potentially more difficult to tolerate.
Aripiprazole (Abilify), which is FDA-approved for tics, is often Dr. Mitrani’s first choice among the antipsychotic medications. Abilify is a second-generation, or atypical, antipsychotic, a group of medications that have fewer side effects than older antipsychotics. Side effects of Abilify can include restlessness, agitation and weight gain.
Haloperidol (Haldol) is also effective for tics, but it’s an older antipsychotic with more side effect concerns, Dr. Mitrani notes. “I’ve only had one patient ever on Haldol, and he tolerated it well and it really helped with his tics when other things did not.”
Risperidone (Risperdal) is another atypical antipsychotic that can help, but its side effects tend to be worse than Abilify. Risperidone can cause more concerning weight gain and metabolic, neurological, and hormonal changes that can be harmful. Sometimes other medications are used to manage the weight gain from antipsychotics.
When kids with tics also have ADHD
More than three-quarters of kids diagnosed with a tic disorder also have another disorder. When a child has multiple disorders, a clinician will want to evaluate which is causing the child the most difficulty and prioritize treating that.
The most common co-occurring disorder with tics is ADHD. “If tics are the bigger problem, we would start with treating them,” says Dr. Mitrani. “If the ADHD is the bigger problem, which it typically is, we usually treat that first.”
In the past, it was recommended that children with tics and ADHD avoid stimulant medication, based on research that showed it made tics worse. But newer studies counter that finding, Dr. Mitrani notes, concluding that the old research was based on very high doses of amphetamine-based medications. To lower the risk of exacerbating tics, he recommends starting kids with ADHD and tics on methylphenidate-based medication.
“If your child is starting a stimulant,” he adds, “and you see worsening of tics — and it’s clearly related to when the stimulant is in their system — the best approach might be a lower dose of stimulant combined with guanfacine or clonidine.”
One advantage to that combination, he notes, is that kids with ADHD who have behavior problems can benefit from the guanfacine or clonidine being active in the mornings before the stimulant starts working and in the evenings when it’s out of their system.
Kids with other co-occurring disorders
When children with tics have other co-occurring disorders, such as anxiety, OCD, or depression, treating them with medication needs to be done very carefully, Dr. Mitrani says. Since children are typically not bothered by the tics themselves, it’s almost always the other disorder that is more problematic for them. And, he adds, when the other problems cause distress, it can make the tics worse.
For anxiety, OCD, and depression, the first-line medication treatment is an antidepressant. Antidepressants can actually help alleviate tics indirectly, since they reduce anxiety. “Stress increases tics, so if there is significant anxiety and you treat the anxiety, the tics may get better,” Dr. Mitrani says. “And then maybe you don’t need the guanfacine or clonidine. But again, it depends on what the co-occurring disorders are and what’s the bigger problem for the child.”
Monitoring medication for tics
Due to the waxing and waning nature of tics, it can be challenging to see the full effect of medication and other interventions. It is important to give medication enough time to work, Dr. Mitrani notes, typically a few weeks, to see if the overall pattern, frequency, and severity of tics has improved. And children who are being treated should continue to be monitored regularly for any changes, as tics can recur or worsen, especially when a child is excited, tired, or experiencing more stress.
Most children with tics see a natural improvement or even resolution of tics as they progress through adolescence. If there seems to be a long-standing improvement, it is appropriate to consider reducing or stopping medication, especially if the child is experiencing side effects, Dr. Mitrani notes. If tics continue and are causing distress, it is important to keep treating them.
A child going off any of these medications — alpha agonists or antipsychotics — should do so gradually, by having their dose reduced over weeks or even longer, to avoid unpleasant or dangerous side effects of sudden withdrawal.
