Therapeutic doses and side effects
Therapeutic doses vary widely between patients, and depend on sex, other drugs, race and age. The manufacturers of Lamictal state that a mood lifting effect may be felt at a dose of 25-100 mg, while mood stabilising effects are expected at doses of 100-200 mg.
In contrast to the majority of antiepileptic drugs, women usually suffer from more side effects than men, and these side effects are more severe. The oral contraceptive pill reduces levels of Lamictal in the body, and so women on the oral contraceptive pill may find they require a higher dose than they would otherwise.
In general, white people require 25-33pc higher doses than non white people in order to feel a therapeutic effect. Rashes are a relatively common side effect of Lamictal, with about 10 percent of people experiencing a rash of some sort. In rare cases a rash may indicate a serious reaction, known as Stevens-Johnson Syndrome, and so it is advised that any rash is reported to a doctor immediately.
As with all medications you should consult your doctor first. This article is not intended to replace the medical advice of a professional physician.
