Hi, different meds work for different children despite them being the same drug.
My son took ritalin 10mg and had fantastic instant results when he was age 9, the paeds then wanted to try him on long acting ritalin - this made him depressed with a very low mood, after 1 week. We reverted to ritalin, all good again. Then they tried Equasim - disrupted his sleep and gave him stomach ache, after a week the doctors took him off it again (as side effects should become minimal after 3 days we were told). Returned to ritalin.
Two years later the ritalin not working as well (this followed a huge growth spurt) so increased to 20 mg, twice daily (to help with homework and after school activities) worked well for over a year.
Then this year in preparation for going to secondary school, they decided to try him on Concerta, this made his appetite non-existent while active in his system all day, and then he could not sleep as well at night, and was ravenous in the early hours of the morning..... and no help at all with his concentration and ADHD!
So we are back with ritalin, now 30mg morning and 20mg afternoon. It is working fine again. He is growing very tall, so not affecting his growth etc.
But each of these short-acting ritalin, concerta, long-acting ritalin and equasim, are all exactly the same drug, only the release of the drug is different. So please don't spend a long time on a drug if it is not working, try different dosage or different type. Don't put up with side effects that don't help.
For our boy the short-acting ritalin does everything to help with concentration and distractability, and no bad side effects. It gives him what he needs, and it works really well. There is a huge difference between when he has it and when he doesn't.
I hope you find the right thing that works for you soon.
