Antiepileptic (sodium channel blocker)
Lamotrigine when planning pregnancy
For couples trying to conceive, every chronic medication deserves a careful pre-pregnancy review. Lamotrigine (Lamotrigine) at 25mg, 50mg, 100mg, 200mg may need to be continued, switched, or stopped before conception, depending on the active ingredient Lamotrigine and the indication. The right answer is rarely the same for everyone and rarely "just stop the medication."
Pre-conception review of Lamotrigine
According to the prescribing information for Lamotrigine, the pre-conception decision balances the risk of the medication during pregnancy against the consequences of leaving the underlying condition untreated. Some Antiepileptic (sodium channel blocker) medications are continued safely through pregnancy; others are switched to safer alternatives before conception or in early pregnancy. Lamotrigine is a phenyltriazine that selectively blocks voltage-gated sodium channels, stabilising neuronal membranes and reducing the release of excitatory neurotransmitters, particularly glutamate.
Effect on fertility itself
Some medications affect fertility directly — by altering ovulation, sperm parameters, hormonal balance or libido. Whether Lamotrigine has any documented effect on fertility depends on Lamotrigine; the prescribing information notes any data. Anyone trying to conceive should discuss Lamotrigine with the prescriber and a fertility specialist if conception is taking longer than expected.
