Hello thanks for asking from HCM for your health related queries I can understand your concern, febrile seizures are common in a number of children. In most cases control of fever results in control of seizures, but now the seizures have progressed to generalised seizures. Keppra is LEVETIRACETAM and the drug is used commonly for seizures but the drug is not approved as mono therapy for generalised tonic clonic seizures (Grandmal seizures). Her drooling, clenching of teeth could be occurring due to seizures only. I would advise you to take her to a doctor again for reevaluation. She should be checked for serum calcium levels to rule out hypocalcemia (low calcium levels are commonly found in seizures in children). Also EEG should find out any seizure focus and to localise the seizures. Medicines like Sodium Valproate, Carbamazapine etc can be used to control her seizures. As she is less than 4 years old then drugs like Phenytoin can also help her. These medicines are broad spectrum anti-seizure drugs and will control her seizures. If she develops fever at any time try to give her cold sponging and paracetamol to control fever. Visit her doctor for prescription. Thanks, hope this helps you. Take care
