My 16 year old daughter just started to take zonisamide for uncontrolled Epileptic seizures. She took 25mg for one week and now started taking 50mg, two days ago. She is complaining of severe back pain, and just said that she was dizzy and felt that she was going to pass out. She is in bed resting. Any advise?
Make sure she is Chat Doctor.  U need to take her to the hospital and have a blood work done to rule out metabolic acidosis. Make sure she does not have a fever. The dizziness could be due to zonisamide overdose, and you should get in touch with the prescribing doctor immediately
