Valproate

an antiepileptic drug

Valproate or VPA is a drug with the different forms, valproic acid, Sodium Valproate and Valproate semisodium. It is mostly used to treat epilepsy and bipolar disorder. It is also used to prevent migraines.[1] It is useful to prevent some kinds of seizures. It can be given intravenously or by mouth.

Common side effects of this medication are sleepiness, dry mouth, weakness, vomiting and nausea. Serious side effects can include liver problems, pancreatitis and an increased suicide risk. Valproate is known to cause birth defects and miscarriages in pregnant women who use the medicine,so it is not recommended for women who are pregnant or able to become pregnant to take Valproate.

Overdose and poisoningEdit

Too much valproic acid can result in sleepiness, shaking, near unconsciousness, shallow breathing, coma, metabolic acidosis, and death. Normal plasma valproic acid levels are in a range of 20–100 mg/l during managed treatment, but may reach 150–1500 mg/l after serious poisoning.[2]
