Women who could become pregnant
Before you start taking Depakote 500mg Tablets, your doctor should discuss with you the possible problems when it is taken in pregnancy.

■ You should use an effective method of contraception and talk to your doctor before planning pregnancy.

Well before you become pregnant it is important to discuss pregnancy with your doctor and, if you have one, your specialist. This is to make sure that you and your doctor agree that you should have Depakote 500mg Tablets if you become pregnant. Women taking Depakote 500mg Tablets during pregnancy have a higher risk than other women of having a child with an abnormality. The chance of abnormalities is increased if you are also taking other medicines for epilepsy at the same time.

Women who take Depakote 500mg Tablets during pregnancy may be more likely to have a baby with spina bifida. Taking folic acid 5mg each day as soon as you stop contraception may lower the risk of having a baby with spina bifida.
There is also an increased risk of other birth defects. These other defects can usually be detected in the first 3 months of the pregnancy using routine antenatal screening, blood tests and ultrasound scans.
Pregnant mothers who take Depakote 500mg Tablets may have babies with:
■ blood clotting problems (such as blood not clotting or not clotting very well).This may appear as bruising or bleeding which takes a long time to stop.
