Methsuximide
Summary
Methsuximide is an anticonvulsant medication used to control absence seizures, also known as petit mal seizures, particularly when other treatments are ineffective.
Methsuximide works by decreasing abnormal electrical activity in the brain, which helps to control absence seizures. It suppresses the spike and wave activity associated with lapses of consciousness, reducing the frequency of epileptic attacks.
The usual starting dose for Methsuximide in adults is 300 mg per day. The dose may be increased weekly by 300 mg per day up to a maximum of 1.2 g per day depending on the patient's response and tolerance. For children, the dosage should be determined by a healthcare provider based on the child's weight and medical condition.
Common side effects of Methsuximide include drowsiness, dizziness, nausea, vomiting, and headaches. Serious adverse effects can include blood disorders, liver issues, and suicidal thoughts.
Important warnings for Methsuximide include the risk of suicidal thoughts or behavior, blood disorders, and liver issues. It should not be used by individuals allergic to succinimides. Patients should be monitored for mood changes and signs of infection, and liver function should be checked regularly.
