People wuth autism often have comorbidities. These are the things that are medicated. So, there could be many different medications prescribed. They often have attention problems, so an ADHD med like Adderall or Guanafacine. Sometimes they have OCD that interferes with their ability to function, so maybe Prozac or Zoloft. They often have anxiety disorders that those kind of drugs would help also. Sometimes people on the spectrum need an antipsychotic like Risperdal or Abilify. Medications are for symptoms. Autism is different for everyone.

I was going to try hydroxyzine because it has low side effects and is an antihistamine that has a calming, sedative effect. My son is 4 years old so a bit young for any of the other options. He is still struggling with language/talking and we feel if he could focus on learning instead of getting distracted it might help.

@A MyAutismTeam Member Have you tried n acetylcysteine instead of Risperdal?

Risperidone is medicine that helps with symptoms of some mental health conditions such as:

schizophrenia (where you may see, hear or feel things that are not there or you believe things that are not true or you feel unusually suspicious or have muddled thoughts)
mania symptoms of bipolar disorder, where your mood changes between feeling highly excited (mania) and very low (depression)
aggressive or agitated behaviour in children (over 5 years) or young people with learning disabilities
aggressive or agitated behaviour in adults with Alzheimer's disease
It's an antipsychotic medicine. It does not cure your condition but it can help the symptoms.

Risperidone is only available on prescription.

It comes as tablets (including tablets that dissolve in your mouth) and a liquid that you drink.

It can also be given as an injection (for schizophrenia only).

2. Key facts
Risperidone works by affecting chemical messengers in the brain (neurotransmitters) like dopamine. It does not cure your condition but it helps to keep your symptoms under control.
Risperidone does not work straight away. It can take several days or even months for some symptoms to get better.
Common side effects include feeling sleepy, problems with your movement and headaches.
It can make you feel more hungry than usual, so you may put on weight.
It's best not to drink alcohol for the first few days of treatment until you see how the medicine affects you.
3. Who can and cannot take risperidone
Risperidone can be taken by most adults and children aged 5 years old and older.

have a heart problem (including arrhythmia)
have low blood pressure (hypotension)
have had a stroke or are at high risk of having a stroke
