HHS Vulnerability Disclosure, Help However, available data also suggest that seizures and epileptic discharges, especially temporal lobe epilepsy, may negatively affect ovarian function and ovulation via disturbances in the hypothalamicpituitary axis.2527, It is well established that enzyme-inducing AEDs may increase sex hormone-binding globulin and induce the metabolism of sex steroid hormones, thus reducing the serum concentration of free and total sex hormones.28,29, Valproate, one of the most frequently used AEDs, can induce polycystic ovary syndrome.30 This syndrome consists of polycystic ovaries, hyperandrogenism, menstrual disturbances, and anovulatory cycles. Lamotrigine (Lamictal) has been associated with a rare, but serious and life-threatening adverse reaction called hemophagocytic lymphohistiocytosis (HLH), which can lead to multi-organ failure .

First, lamotrigine concentrations fall by 50%60% and seizure aggravation may occur when EE is added.5153 This usually requires a considerable increase, and often a doubling, of the lamotrigine dose, in order to avoid seizure breakthrough.

Most importantly, the effects of HC (especially DMPA) and enzyme-inducing AEDs on bone mineral density may add up, which is another reason to avoid this problematic combination. Until then, HC should be regarded as non-safe when combined with enzyme-inducing AEDs, and additional contraceptive methods (barrier methods) be employed.

Moreover, many WWE use enzyme-inducing AEDs that may impair the efficacy of highly effective HC.8, It might be speculated whether better education of WWE could reduce the proportion of unplanned pregnancies. lamotrigine oral brand names and other generic formulations include: Lamictal ODT Oral, Lamictal ODT Starter (Blue) Oral, Lamictal ODT Starter (Green) Oral, Lamictal ODT Starter (Orange) Oral, Lamictal Oral, Lamictal Starter (Blue) Kit Oral, Lamictal Starter (Green) Kit Oral, Lamictal Starter (Orange) Kit Oral, Lamictal XR Oral, Lamictal XR Starter (Blue) Oral, Lamictal XR Starter (Green) Oral, Lamictal XR Starter (Orange) Oral.

Banerjee PN, Filippi D, Allen Hauser W. The descriptive epidemiology of epilepsy-a review. Indeed, modern oral HC preparations typically contain 1.52 times the ovulation-inhibiting progestin dose.43 However, as enzyme induction affects not only EE but also progestins,45 even the contraceptive effect of a high progestin dose may be impaired by enzyme-inducing AEDs, and clinical evidence for the high progestin concept is lacking.

You should avoid or limit the use of alcohol while being treated with lamoTRIgine. Given the serious and potentially fatal consequences of uncontrolled epilepsy for both the mother and the unborn child, as well as the significant risk of harmful pre- and postnatal effects that several AEDs may have on the child, unplanned pregnancy in WWE should be avoided and adherence be improved.
