If your child has a diagnosis of autism, you might have heard that there are different medications that may be able to ease some of your child’s symptoms. While therapy is the recommended route for children with autism, in some cases a doctor may prescribe medication that can help your child function. Dr. Lukas Propper, a prominent child psychiatrist, notes, “The use of medication is often necessary in patients with high-risk behaviours to decrease the severity of symptoms before any behavioural intervention can be undertaken.”
But while autism can be hard to navigate, prescription medication is a maze of its own. There is no medication that helps autism’s 3 characteristics: communication difficulties, repetitive behaviors, and executive functioning deficits. What medication can help with is some of the symptoms that come along with autism. Many medications prescribed for autism are off-label — the FDA approved them for other disorders and although they are used to alleviate autism-related symptoms that isn’t their official prescribed use.
Drugs used for autism will have different effects on different people, and not everything works for everyone. Sometimes, a medication’s effects wear off over time, and sometimes people develop a sensitivity to it over time. What’s more, most drugs have some negative side effects. If you go down the medication route, make sure it will work for your child.
Typically, these drugs would be prescribed by your child’s psychiatrist, developmental pediatrician, or pediatric neurologist. Always speak to your child’s doctors about medications and their side effects.
Common medications
While every case is different, there are certain medications that are more commonly described. To make things easier, we put together a partial autism medication list laying out the purpose, benefits, and cautions of common autism drugs.
This isn’t an all-encompassing list — it only lists the most common medications. This list discusses the most common uses and side effects, but it doesn’t discuss everything. For more information, speak to your child’s doctor.

Medications usually have side effects, and autism meds are no exception. Some side effects are mild, some are severe, and not everyone experiences them. Look into potential side effects before you start any medication and discuss any concerns with your child’s doctor.
There’s no way to know if a drug will work for your child without trying it out. Finding the right medication and the right dosage takes trial and error, and it can be a hard transition.
“Careful monitoring of any adverse effects is required,” says Dr. Plopper. When your child starts a new medicine or a new dosage, keep a close watch. Look out for any changes in behavior or overall health and report any concerns to their doctor right away.
In general, medications for autism are recommended as a supplement to therapies like ABA, OT, speech, or early intervention. If your child is not receiving therapy, look into that first as it is proven to bring about positive results without the risk of side effects.
It’s important to note that autism is not a disease that can be cured. Since autism is defined by developmental delays, it often comes together with other symptoms. These symptoms are what can be alleviated through therapy and sometimes medications. “Currently, there is no medication that can cure autism spectrum disorder (ASD) or all of its symptoms. But some medications can help treat certain symptoms associated with ASD, especially certain behaviors,” the National Health Institute explains on its website.
If you’re new to the world of autism, reach out to an expert for help. Doctors like a developmental pediatrician or child psychologist and therapists like BCBAs, OTs, PTs, and SLPs are all experienced with supporting children on the spectrum and can provide support along the way.

No. There is currently no medication that treats the core characteristics of autism—such as communication difficulties, repetitive behaviors, or executive functioning deficits. Medications are used to manage associated symptoms like irritability, anxiety, or sleep issues.
Who can prescribe autism medications for my child?
Autism-related medications are usually prescribed by a child psychiatrist, developmental pediatrician, or pediatric neurologist. Always consult these professionals before starting any medication.
Are medications for autism FDA-approved?
Some medications like Risperidone and Aripiprazole are FDA-approved for irritability in autism. Others are used off-label, meaning they are prescribed for autism-related symptoms but are officially approved for other conditions.
What are the most common medications for autism symptoms?
Common medications include Leucovorin, Risperidone, Aripiprazole, Melatonin, Guanfacine, Sertraline, and Fluoxetine. Each targets specific symptoms like irritability, sleep disruption, or anxiety and may have side effects.
Do autism medications have side effects?
Yes. Side effects vary by drug and individual. They can range from drowsiness and weight changes to more serious issues like mood swings or movement disorders. Always review potential side effects with your doctor.
Will the same medication work for every child?
No. Every child responds differently to medication. Effects can vary or diminish over time, and sensitivity may increase. Medication should be tailored to the child’s specific needs under professional guidance.
Should medication replace therapy for autism?
No. Medication is a supplement to therapy, not a replacement. Therapies like ABA, OT, speech, and early intervention are proven to help without the risks associated with medication side effects.
How do I know if a medication is helping my child?
Monitor behavior and health closely after starting a medication. Report any changes or concerns to your doctor. Finding the right medication and dosage often involves trial and error.
Can medications cure autism?
No. Autism is not a disease and cannot be cured. Medications help manage co-occurring symptoms, not the core diagnosis itself.
Where can I get help deciding on autism treatment options?
Reach out to a developmental pediatrician, child psychologist, or therapy professionals like BCBAs, OTs, PTs, or SLPs. The team at Circle Care Services is also available to support and guide families.
