I take phenobarbitol and phenytoin sodium. effect on pregnancy ?

A doctor has provided 1 answer

These meds a problem: Both meds are listed as category "d", known to have adverse effects on the fetus.(iugr, bone changes, small head, mental retardation) the phentoin is regarded as the worse of the two. Most ob's would chose to have you on one of the newer meds with less risks.

A member asked:

I'm currently taking 300 mg of phenytoin daily for epilepsy. I'm also taking a calcium and vitamin d3 supplement. The D3 is a fairly high dosage due to the phenytoin. Should I take magnesium? If so how much and with the D3 or not?
