HI THERE,
My son is also aggressive, extreme emotions and hard to settle down. He is also aggressive towards himself and others. Recently, We've started him on Cannabis liquid drops. Don't worry No THC & JUST CDC. Completely all natural. No side effects unless you misuse it and exceed the dosage. Anyway, at first, I couldn't really say if it worked or not UNTIL we went out. In all Honestly, it's costly $75 for a small bottle, but there is a difference. He does get anxious, but I AM ABLE to calm him down without removing him to the side. Makes things a lot easier. I have mentioned it to my dr. He is his first patient, but know it is becoming more known and a lot more positive results are coming out of it.

How old? My neuro tried to rx my daughter but we decided to do so as last resort. Biomedical treatment (first no gluten) with increased behavioral therapy is first.
I use the safe zone technique to curb meltdowns, works pretty well so far.
Also is it possible he knows he can get away with bad behavior at home?
Lastly, I don't know much about rx bc I'm trying other methods first.

Vitamin D helped our son with aggression problems. You need to get it checked by a doctor with a blood test to see how much is needed though. Dr. Cannell, a psychiatrist in California has had some success with vitamin D and people on the autism spectrum.

Ser tra line didn't work for us. Maybe Quillivant.

After doing my research and consulting with my physician it is completely safe for kids (smallest dosage) .my husband and I tried it a few days before giving it to him. Theres no difference we felt (using a largest dose). Also the person I ordered it from who i met at a convention started this. Her son has autism as well. & i had the pleasure of meeting the little fellow. I'm a strong believer of it but to each its own. Not much studies have been done on autism to support it but its well worth trying anything. I've never given my son prescription meds so I cant compare. Only diet change and that is also something that made differences in his behavior.
