A low concentration is reached in breast milk. It is commercialized in several countries (not in Spain) together with Pyrimethamine (see the latter drug) as an anti-malarial drug: Fansidar: 20 parts of Sulphadoxine by 1 of Pyrimethamine. Manufacturers give a dosage for children weighing more than 5 kg.
