when to assess depakote level after treatment initiation

Your valproate level should be drawn 12 hours after your nighttime dose. You should not vary this by more than 30 minutes either way, if possible. If you get your blood drawn after fewer than 11 hours have passed or after more than 13 hours after you take your nighttime dose the result is likely to be unhelpful.

In general, when taking divalproex-ER once daily in the morning, a blood sample collected at 21-24 h after OD dose of ER preparation is expected to have a concentration within 3% of the trough value. Conversely, blood sample 12-15 h after the last dosing will give a value that is 18-25% higher, than the actual trough value. The current study is undertaken with an aim to provide …

What is depakote used for?

Overview. Depakote (Valproic Acid) is a drug used for the treatment of petit mal, grand mal, mixed and akinetic-myoclonic seizures. Valproic acid is a prescription medication that has been proven effective in the treatment of epilepsy, chronic migraine headaches, and manic episodes associated with bipolar disorder, also known as manic depression. ...

Does Depakote interact with other drugs?

Drug Interactions. Depakote may interact with other drugs, including other antiepileptic drugs. Phenobarbital, Dilantin (Phenytoin), Tegretol (Carbamazepine) and Lamictal can decrease the Depakote blood level. The blood levels of other antiepileptic drugs can also be affected by Depakote.

What is the drug used for seizures?

Depakote (Valproic Acid) is a drug used for the treatment of petit mal, grand mal, mixed and akinetic-myoclonic seizures . Valproic acid is a prescription medication that has been proven effective in the treatment of epilepsy, chronic migraine headaches, and manic episodes associated with bipolar disorder, also known as manic depression. The valproic acid level in the blood must be maintained within a narrow therapeutic range. Dosage which is too low or too high can fail to alleviate or even worsen a person’s symptoms.

What is valproic acid?

Valproic acid is an 8-carbon 2-chain fatty acid that is metabolized by the liver and processed at a variable rate based on the patient’s liver function and age, in addition to patient’s other routine medications with which valproic acid may interact. At therapeutic concentrations, valproic acid mediates prolonged recovery of voltage-activated Na+ channels, thereby inhibiting repetitive firing induced by depolarization of cortical and spinal cord neurons. Its action is similar to that of other common anticonvulsants, such as phenytoin and carbamazepine.

What is the therapeutic range of Valproic acid?

Its action is similar to that of other common anticonvulsants, such as phenytoin and carbamazepine. The therapeutic range for valproic acid (total) is 50-125 µg/mL. The toxic level is greater than 150 µg/mL. The therapeutic range for valproic acid (free) is 6-22 µg/mL.

Is Valproic acid safe for seizures?

In general, if the valproic acid result is within the therapeutic range, the person is not having recurrent seizures, mood swings, or migraines, and is not experiencing significant side effects, then the dosage is considered adequate.

What are the side effects of a syringe?

These side effects may include some or a combination of the following: Gastrointestinal symptoms such as nausea, vomiting, diarrhea. Dizziness. Unusual weight gain or loss.

Is Depakote monotherapy or adjunctive?

Depakote is indicated as monotherapy and adjunctive therapy in the treatment of patients with complex partial seizures that occur either in isolation or in association with other types of seizures. Depakote is also indicated for use as sole and adjunctive therapy in the treatment of simple and complex absence seizures, and adjunctively in patients with multiple seizure types that include absence seizures.

Is Depakote contraindicated for UCD?

Depakote is contraindicated in patients with known urea cycle disorders (UCD). Hyperammonemic encephalopathy, sometimes fatal, has been reported following initiation of valproate therapy in patients with urea cycle disorders, a group of uncommon genetic abnormalities, particularly ornithine transcarbamylase deficiency. Prior to the initiation of Depakote therapy, evaluation for UCD should be considered in the following patients: 1) those with a history of unexplained encephalopathy or coma, encephalopathy associated with a protein load, pregnancy-related or postpartum encephalopathy, unexplained mental retardation, or history of elevated plasma ammonia or glutamine; 2) those with cyclical vomiting and lethargy, episodic extreme irritability, ataxia, low BUN, or protein avoidance; 3) those with a family history of UCD or a family history of unexplained infant deaths (particularly males); 4) those with other signs or symptoms of UCD. Patients who develop symptoms of unexplained hyperammonemic encephalopathy while receiving valproate therapy should receive prompt treatment (including discontinuation of valproate therapy) and be evaluated for underlying urea cycle disorders [see Contraindications (4) and Warnings and Precautions (5.9)].

What is the drug used for manic episodes?

Depakote (divalproex sodium) is a valproate and is indicated for the treatment of the manic episodes associated with bipolar disorder . A manic episode is a distinct period of abnormally and persistently elevated, expansive, or irritable mood. Typical symptoms of mania include pressure of speech, motor hyperactivity, reduced need for sleep, flight of ideas, grandiosity, poor judgment, aggressiveness, and possible hostility.

Is Depakote safe for migraines?

Depakote is indicated for prophylaxis of migraine headaches. There is no evidence that Depakote is useful in the acute treatment of migraine headaches. Because it may be a hazard to the fetus, Depakote should be considered for women of childbearing potential only after this risk has been thoroughly discussed with the patient and weighed against the potential benefits of treatment [see Warnings and Precautions (5.2) and Patient Counseling Information (17.3)].

Is Depakote a monotherapy?

Depakote tablets are administered orally. Depakote is indicated as monotherapy and adjunctive therapy in complex partial seizures in adults and pediatric patients down to the age of 10 years, and in simple and complex absence seizures. As the Depakote dosage is titrated upward, concentrations of clonazepam, diazepam, ethosuximide, lamotrigine, tolbutamide, phenobarbital, carbamazepine, and/or phenytoin may be affected [see Drug Interactions (7.2)].

Can you take Valproate while pregnant?

Because of the risk to the fetus of neural tube defects and other major congenital malformations, which may occur very early in pregnancy, valproate should not be administered to a woman of childbearing potential unless the drug is essential to the management of her medical condition. This is especially important when valproate use is considered for a condition not usually associated with permanent injury or death (e.g., migraine). Women should use effective contraception while using valproate. Women who are planning a pregnancy should be counseled regarding the relative risks and benefits of valproate use during pregnancy, and alternative therapeutic options should be considered for these patients [see Boxed Warning and Use in Specific Populations (8.1)].

Can valproate cause neural tube defects?

Pregnancy registry data show that maternal valproate use can cause neural tube defects and other structural abnormalities ( e.g., craniofacial defects, cardiovascular malformations and malformations involving various body systems). The rate of congenital malformations among babies born to mothers using valproate is about four times higher than the rate among babies born to epileptic mothers using other anti-seizure monotherapies. Evidence suggests that folic acid supplementation prior to conception and during the first trimester of pregnancy decreases the risk for congenital neural tube defects in the general population.
