DS aged 8 ASD has recently been prescribed Rubifen to help his concentration. He started taking it a few days ago and it seems to be having a positive effect unlike the Concerta 18 which he tried before. However, on one hand the medication is proving beneficial for everyone but on the other hand, I don't like the idea of him taking medication long-term. Just wondering if anyone has any experience of Rubifen and any possibly adverse long-term side-effects. Thanks.
