Dose Optimization
Dose optimization of ASMs is also important — and for this to be accurate, it’s important to document an individual’s optimal ASM serum levels before pregnancy that can be used as a baseline target during pregnancy. However, Dr. Tomson noted, this information is not always available.
He pointed out that, with many ASMs, there can be a significant decline in serum concentration levels during pregnancy, which can increase seizure risk.
To address the uncertainty surrounding this issue, Dr. Tomson recommended that physicians consider future pregnancy when prescribing ASMs to women of childbearing age. He also advised discussing contraception with these patients, even if they indicate they are not currently planning to conceive.
The data clearly show the importance of planning a pregnancy so that the most appropriate and safest medications are prescribed, he said.
