The valproic acid test is used to measure and monitor the amount of valproic acid in the blood and determine whether the drug concentration is within the therapeutic range. Maintaining the right therapeutic level of Valproic Acid is vital for successful treatment. Dosage which is too low or too high can fail to alleviate or even worsen a person’s symptoms.
Valproic acid is used alone or with other medications to treat certain types of seizures. Valproic acid is also used to treat mania (episodes of frenzied, abnormally excited mood) in people with bipolar disorder (manic-depressive disorder; a disease that causes episodes of depression, episodes of mania, and other abnormal moods). It is also used to prevent migraine headaches, but not to relieve headaches that have already begun. Valproic acid is in a class of medications called anticonvulsants. It works by increasing the amount of a certain natural substance in the brain.
