Maternal effects of regular salicylate ingestion in pregnancy.
6.6% of all Australian patients attending an antenatal clinic were found to be taking salicylate preparations regularly, most commonly in powder form and almost always as self-medication. In this group of salicylate takers there was an increased incidence of anaemia, anti-partum and post-partum haemorrhage, prolonged gestation, complicated deliveries, and perinatal mortality compared with non-takers. These findings suggest that regular salicylate consumption has detrimental effects in pregnancy. Routine antenatal urinary screening for salicylate in pregnancy is recommended.
