Activated charcoal has such great absorbtion qualities but that can cause problems when mixed with medications. I urged my adult son used it for his diarrea and I think it absorbed too much of his seizure medication and he began to have tiny petit mal seizures within a while. Just be careful that you don't absorb a life saving medicine to cure diarrhea.
It is true you are not supposed to take this medicine within a few hours of taking other medicines. I too have seizures and I make sure to take charcoal many hours before I take other medicines.
