Breastfed infants exposed to lamotrigine faced a low risk of toxic effects.
Article in Acta paediatrica (Oslo, Norway : 1992), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimWe aimed to investigate plasma lamotrigine concentrations and clinical effects in infants exposed to lamotrigine through breastfeeding.
methodsThis was a retrospective study of mother-infant dyads in a clinical follow-up programme in Stockholm, Sweden. Data were collected from medical records.
resultsWe included 47 breastfed infants, born from 2011 to 2021, with a median gestational age of 39 + 6 weeks/days and a median birth weight of 3420 g. The median lamotrigine concentration in the infants' plasma was 2.5 (range 2.5-14.0) μmol/L. These concentrations correlated significantly with both the maternal plasma concentrations and the maternal doses (R = 0.79, p < 0.001 versus R = 0.54, p < 0.001). During the follow up, lamotrigine concentrations within the reference range for epilepsy treatment were detected in six (14%) infants and one had clinical symptoms that were probably related to lamotrigine exposure. Liver transaminases were elevated in three of 21 infants. All infants whose mothers had a dose of 150 mg or less had undetectable plasma concentrations and no symptoms during follow up.
conclusionInfants exposed to lamotrigine through breastfeeding had a low risk of toxic effects. All infants whose mothers had low lamotrigine doses had unmeasurable plasma concentrations and no symptoms of lamotrigine exposure. These low-risk infants might be offered a simplified follow up.
