My daughter (18 at the time) has epilepsy and was switched to a new medication. By 9 days into taking the new med she was hearing things that weren’t there and hallucinating. She was hearing a clock ticking in the walls and voices were telling her to harm herself. Obviously I took her to the ER and she spent a long weekend in the psychiatric ward of the hospital. It was truly scary to watch her descend into madness and not know when/if she would come out of it. Thankfully, once the medication was stopped she returned to normal and has been fine ever since. But now whenever her medications are adjusted I get nervous and super vigilant to watch for any signs of negative side effects.
