Depacon

Generic Name: valproate (val-PROE-ate)
Brand Name: Depacon

Liver failure and death from liver failure has occurred in patients taking Depacon. This has usually occurred within the first 6 months of treatment. Tell your doctor right away if you notice symptoms of liver problems (eg, a general feeling of discomfort, sluggishness, unusual tiredness or weakness, swelling of the face, loss of appetite, vomiting, stomach pain, dark urine, pale stools, or yellowing of the skin or eyes). In patients who have seizures, loss of seizure control may occur. You should have lab tests done before and during treatment to check for liver problems. Be sure to keep all doctor and lab appointments.

Children younger than 2 years old have an increased risk of fatal liver problems, especially if they take more than 1 seizure medicine or have a metabolic disorder, a severe seizure disorder along with mental retardation, or organic brain disease. Discuss any questions or concerns with your doctor.

There is an increased risk of liver failure and death from liver failure in patients who have a genetic liver problem caused by a mitochondrial disorder (eg, Alpers-Huttenlocher syndrome). You may need to have a special genetic test to check for this condition. Certain patients who have known or suspected mitochondrial disorders should not take Depacon. Talk with your doctor for more information.

Depacon can cause severe birth defects if it is used during pregnancy. It can also cause the child to have a lower IQ. Do not take Depacon to prevent migraine headaches if you are pregnant. If you are pregnant and take Depacon for seizures or bipolar disorder, talk to your doctor to decide if you will continue to take Depacon.

If you are able to become pregnant, you must use an effective form of birth control while you take Depacon. Contact your doctor right away if you become pregnant or think you may be pregnant while taking Depacon.

Depacon comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get Depacon refilled.
