The most commonly used treatment for grand mal seizures is anti-seizure medication such as valproic acid, carbamazepine, phenytoin and oxcarbazepine, according to the Mayo Clinic. Physicians work closely with patients to monitor the effectiveness of medications.
Anti-seizure medication is administered at a low dosage when seizures begin, and the dosage is gradually increased until seizures and conditions that cause seizures, such as epilepsy, are controlled, according to the Mayo Clinic. To control and prevent grand mal seizures, medication must be taken exactly as prescribed as the timing of medication contributes to the occurrence of seizures.
Mild side effects of anti-seizure medication may include dizziness, weight gain and fatigue, according to the Mayo Clinic. In extreme cases, patients may experience a loss of coordination, skin rashes, mood disruption, extreme fatigue or speech problems while taking prescribed medication to control grand mal seizures.
Patients often experience grand mal seizures in two stages, according to the Mayo Clinic. The tonic phase is when loss of consciousness occurs and the patient may fall as the muscles contract. The clonic phase occurs when a patient convulses when the muscles flex and relax. Some people may experience headaches, fatigue or confusion following a grand mal seizure.
