Health Canada Endorsed Important Safety Information on LAMICTAL (lamotrigine): Important Safety Information Concerning Interactions of the Anti-epileptic Drug Lamictal
In September 2004, GlaxoSmithKline Inc. distributed a letter to Canadian healthcare professionals concerning the safety of the anti-epileptic drug, Lamictal. Women who combined Lamictal with their birth control pills have reported the following:
- unexpected pregnancies
- menstrual bleeding disorders (e.g. breakthrough bleeding)
Health Canada advised women to inform their doctors if they are taking birth control pills or other female hormonal treatments (e.g. hormone replacement therapy). Patients should never start or stop their medication without consulting a physician first.
