Methylprednisolone Levels and Effects while Breastfeeding

Summary of Use during Lactation

Limited information indicates that maternal doses of methylprednisolone up to 8 mg daily produce low levels in milk and would not be expected to cause any adverse effects in breastfed infants. With high maternal doses, especially intravenous doses as in multiple sclerosis relapse or monthly therap, avoiding breastfeeding during the infusion and for 4 to 48 hours after a dose is recommended by various sources.[1][2] However, this maneuver is not necessary for low doses. Local injections, such as for tendinitis, would not be expected to cause any adverse effects in breastfed infants, but might occasionally cause temporary loss of milk supply.

Drug Levels

Maternal Levels In one woman taking 6 mg daily of methylprednisolone by mouth, 2 peak milk levels occurred: one at 2 hours after the dose and another 8 hours after the dose. Peaks were about 7 mcg/L, while levels fell to about 2.5 mcg/L 6 hours after the dose and to about 1 mcg/L 10 hours after the dose.[3] Infant Levels. Relevant published information was not found as of the revision date.

Effects in Breastfed Infants

None reported with methylprednisolone or any other corticosteroid. None reported with methylprednisolone or any other corticosteroid. Three infants were breastfed from birth during maternal use of methylprednisolone 6 to 8 mg daily with no reported adverse effects up to 3 months.[3][4] In one of the papers, 2 infants had normal blood cell counts, no increase in infections and above average growth rates.[4]

Effects on Lactation and Breastmilk

A patient who was 6 weeks postpartum and predominantly breastfeeding her infant received 24 mg of depot methylprednisolone plus 15 mg of lidocaine intralesionally for tenosynovitis of the wrist. Thirty hours after the injection, lactation ceased. Her breasts were soft and not engorged at that time. Thirty-six hours later, lactation resumed slowly, reaching normal milk production 24 hours later. The author hypothesized that the suppression might have occurred because the injection was in a highly mobile joint, which might have caused rapid release of the corticosteroid.[5] A large dose of triamcinolone injected into the shoulder has also been reported to cause temporary cessation of lactation.[6]

A study of 46 women who delivered an infant before 34 weeks of gestation found that a course of another corticosteroid (betamethasone, 2 intramuscular injections of 11.4 mg of betamethasone 24 hours apart) given between 3 and 9 days before delivery resulted in delayed lactogenesis II and lower average milk volumes during the 10 days after delivery. Milk volume was not affected if the infant was delivered less than 3 days or more than 10 days after the mother received the corticosteroid.[7] An equivalent dosage regimen of methylprednisolone might have the same effect.

A study of 87 pregnant women found that betamethasone given as above during pregnancy caused a premature stimulation of lactose secretion during pregnancy. Although the increase was statistically significant, the clinical importance appears to be minimal.[8] An equivalent dosage regimen of methylprednisolone might have the same effect.
