Hello, I can understand your concern for your daughter. Topamax may cause low concentration span and difficulties with memory which may make your daughter to constantly keep finding words. Other side effects include paresthesia, weight loss, change in taste perception and continuous feeling of tiredness. Lobazam causes dry mouth which can make speech difficult for your daughter. Other side effects of this drug are irritability, headache, nausea and constant feeling of drowsiness. Sugerless gum chewing, constant sipping of water can help with speech difficulties. The prescribing doctor may have found the advantages of these molecules weighing more than adverse reactions and so must have prescribed them. However, if the adverse reactions are too troublesome, you can talk to the doctor to change to a different molecule or adjust doses of the current medications to lessen the side effects. I hope this information helps. Thank you for choosing HealthcareMagic. I wish your daughter feels better soon! Let us know if you have any further queries. Best, Dr. Viraj Shah
