Dear F.,
These medications are very specific. I assume you are working with a good pediatrician? Your child's profile is also very specific. While it can be very challenging to find the best match between your child's needs and medication, please don't expect an instant fix. Sometimes side effects are very different for different people. Definitely check out websites like WebMD, the May Clinic, Stanford and Kaiser.
San Andreas Regional Center is in Campbell, right under the water tower in the old downtown section. It is a fantastic organization filled with wonderful, knowledgeable and sensitive people. The Center is an organization that supports the full gamut of children with all sorts of special needs, not only physical needs such as seizures, but also behavioral, emotional and mental needs. Please contact them at your earliest convenience.
Also contact Parents Helping Parents in Santa Clara, (on Olcott, parallel to Lawrence Expwy, just off 101). They are a resource agency started by parents of children with special needs over 30 years ago. They have classes, support groups and sibling programs. They will find parents who are in the same boat as your are, who will have many resources and tried and true strategies to support you and your family.
These agencies are there to serve you and your child, have loads of resources and support, and are very well funded!
