As with any medication in pregnancy, laxatives should be used with caution (Table 5).

Anthraquinone laxatives such as dantron are associated with congenital malformations.

41,42 Saline osmotic laxatives (magnesium citrate and sodium phosphate) can cause maternal sodium retention while castor oil can initiate premature uterine contractions.43 Mineral oils can theoretically affect maternal absorption of fat-soluble vitamins. In the case of Vitamin K this can lead to hypoprothrombinaemia and haemorrhage. 44 Some laxatives can even produce neonatal diarrhoea.43 Stimulant laxatives such as senna should be used with caution in pregnancy. Senna can be excreted in breast milk.45 In general, the short-term use of stimulant laxatives is considered safe in pregnancy.However, as with the general population, long-term use should be avoided.

Tegaserod is a 5HT4 agonist that has shown considerable promise as a treatment for

constipation-predominant IBS. The American Gastroenterology Association (AGA)

initially considered tegaserod to be low risk in pregnancy.46 However, recent evidence

of an increased incidence of ischemic cardiac and cerebral events in patients using this

medication has led to the United States Food and Drug Administration (FDA) to request

that sale of tegaserod be suspended. The AGA position statement also considers

polyethylene glycol (PEG) to be low-risk in pregnancy and the preferred treatment for

chronic constipation in pregnant women. PEG acts as an osmotic laxative by opposing

the dehydration of bowel contents that would ordinarily lead to increased stool bulk.

The increased retention of water in the colon lubricates and softens the stools. There

are data suggesting some absorption of PEG 3350 in humans.47 However, the small

amounts (1–4%) that are absorbed are excreted unchanged in the urine.
