Hydrocortisone tablets in pregnancy

The NHS says

Hydrocortisone tablets can be taken while you're pregnant.

Your doctor will prescribe them only if the benefits of the medicine outweigh the risks.

If you take hydrocortisone tablets for Addison's disease, it's important to keep taking them all through pregnancy. Your dose may sometimes need to go up, and it's usual to be given higher doses of hydrocortisone by injection while you're giving birth.

8.1 Pregnancy Risk Summary Untreated adrenocortical insufficiency in pregnancy can result in a high rate of complications, including maternal mortality. The use of physiologic doses of hydrocortisone is not expected to cause major birth defects, miscarriage and adverse maternal and fetal outcomes. Available data from observational studies with hydrocortisone use in pregnancy have not identified a clear drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes (see Data ). The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2–4% and 15–20%, respectively.

Hydrocortisone tablets while breastfeeding

The NHS says

Hydrocortisone tablets can be taken while breastfeeding, provided your doctor or midwife is happy that your baby is healthy.

Breast milk naturally contains hydrocortisone, but it's not known how much gets into breast milk when you take hydrocortisone tablets. The amount is thought to be small, and it's unlikely to cause side effects in your baby.

If you're on a higher dose, or need to take it for a long time, your baby may need extra monitoring.

If you take hydrocortisone tablets for Addison's disease, it's important to keep taking them so you stay well. Breastfeeding also has benefits for both you and your baby.

If you have any worries about your baby, call 111 (in the UK) or get in touch promptly with your pharmacist, doctor, midwife or health visitor. This includes if your baby: is not feeding as well as they usually do; is not gaining weight as you'd expect; is vomiting or has diarrhoea; seems irritable or more tired than usual; or has skin reactions, such as rashes.

LactMed says

Hydrocortisone (cortisol) is a normal component of breastmilk, but it has not been studied in milk after exogenous administration in pharmacologic amounts. Although it is unlikely that dangerous amounts of hydrocortisone would reach the infant, a better studied corticosteroid might be preferred. Maternal use of hydrocortisone as an enema would not be expected to cause any adverse effects in breastfed infants. Local maternal injections, such as for tendinitis, would not be expected to cause any adverse effects in breastfed infants. Medium to large doses of corticosteroids given systemically or injected into joints or the breast have been reported to cause temporary reduction of lactation. See also Hydrocortisone, Topical.

Cortisol in breastmilk might have a role in intestinal maturation, the intestinal microbiome, growth, body composition or neurodevelopment, but adequate studies are lacking.[1] Concentrations follow a diurnal rhythm, with the highest concentrations in the morning at about 7:00 am and the lowest concentrations in the late afternoon and evening.[2,3] Cortisol concentration in milk increases with infant age and milk cortisol levels; it decreases with complementary feeding and infant illness.[4,5] Cortisol in milk may protect against later infant obesity, especially in girls;[6] however, in another study, milk glucocorticoid levels were positively associated with percent fat mass, adiposity and head circumference at 1 year of age.[7] Maternal stress can increase breastmilk cortisol levels, especially with preterm births.[8-11] Milk cortisol may mediate infant emotions and infant sleep, but not crying, is correlated with the levels of cortisone and cortisol in milk.[12,13] Some information indicates that maternal adverse childhood experiences may decrease cortisol concentration in their breastmilk.[14]

The US prescribing label says

8.2 Lactation Risk Summary Cortisol is present in human milk. The use of hydrocortisone at a physiologic dose for adrenocortical insufficiency is not expected to adversely affect the breastfed infant or milk production. There are no data on the presence of hydrocortisone in breast milk, the effect on the breastfed infant or on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for ALKINDI SPRINKLE and any potential adverse effects on the breastfed infant from ALKINDI SPRINKLE or from the underlying maternal condition.
