I was taking Phenobarbital in Jr. High age 14. The side effects were very bad with me. I was always tired, and always acted out of it. It seems like my neurologist at the time even tried "Escabarb" for a short time also. It is a long lasting Phenobarbital type medicine. I couldn't stay on this very long. Maybe 6 to 8 months I was on it until an evaluation showed it was effecting my mental attitude. Be careful !!!
I was on it at the age of 16. Tegrital also. I was seizure free at 17. But remember we are all different.
A lot of meds can slow down our learning. That doesn’t make us dumb. We just have to work harder to understanding it.
And don't think that it makes you dumb some meds are even worse
I forgot to mention: phenobarbital also affects your bone density. It has been lowering my bone density for years. I now have osteoporosis in the hip.
