Drug Interactions between lanthanum carbonate and Valproate Sodium

Alcohol can increase the nervous system side effects of valproic acid such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with valproic acid. Do not use more than the recommended dose of valproic acid, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.

Take lanthanum carbonate tablets with food or immediately after a meal to increase absorption by the body. Lanthanum carbonate tablets cannot be dissolved in water and therefore should not be given through feeding tubes because the tube may become clogged. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
