Anticonvulsants (antiepileptic) drugs are commonly used for people with bipolar disorder and are one of several classes of medications considered to be mood stabilizers (along with lithium, calcium channel blockers, and benzodiazepines).
While these drugs were devised for controlling seizures, they are often very effective in stabilizing mood and have been called mood stabilizers for this reason.
While these medications can be very effective, there are important drug interactions you will need to be aware of that could both increase your risk of pregnancy and increase the risks of pregnancy if you were to become pregnant.
