(LifeWire) - The sleep deprivation common to new parenthood is legendary, so the thought of new mothers needing medicinal help for insomnia when they finally collapse into bed seems impossible. But it's not. A handful of over-the-counter (OTC) sleep aids are considered safe for breastfeeding mothers, but they need to balance their needs with the potential risks and side effects these drugs present to their babies.
It seems logical that nursing mothers, who either breastfeed or pump their milk every few hours around the clock, would easily shift into sleep mode once given the chance. Despite mounting sleep debt, however, their rest can easily be disrupted by anything from lingering childbirth discomfort to swollen breasts to anxiety over their new parenting role.
But nursing moms do have a built-in advantage for peaceful sleep compared to those who don't breastfeed. The hormone prolactin is released during nursing and promotes feelings of relaxation and calm in the mothers. Most new mothers do opt to breastfeed for some period of time, according to the US Centers for Disease Control and Prevention, with about 43% still nursing their babies at 6 months of age and 21% still nursing their 1 year olds.
Most OTC sleep aids contain antihistamines, typically used to combat cold and allergy symptoms, such as sneezing, itching and mucus production, but antihistamines also induce drowsiness, making them useful for insomnia. They work by suppressing histamine, a chemical messenger in the brain that fosters alertness.
For short periods, the two active ingredients found in most OTC antihistamines are probably safe for breastfeeding mothers. They are not well studied and do get into breast milk. So, if they are used, it should be limted and the infant should be monitored for drowsiness. Those active ingredients are chlorpheniramine found in Chlor-Trimeton and Aller-Chlor, and diphenhydramine found in Benadryl and Diphenhist. Diphenhydramine is the one most commonly used in sleep aids. Some drugs contain diphenhydramine alone, such as Nytol or Sominex, and others combine it with pain relievers, such as Tylenol PM (acetaminophen and diphenhydramine).
Lactating mothers, however, should not take combination products containing aspirin. Because of its blood-thinning abilities, aspirin sometimes causes rashes or bleeding abnormalities in breastfed babies. Some experts also advise against the use of Aleve (naproxen), particularly long-term, because the medication can gradually accumulate in a baby's body.
Using antihistamines to aid sleep for long periods while breastfeeding is inadvisable, according to the American Academy of Family Physicians, because their active ingredients can interfere with milk production. They can also result in side effects in the baby such as irritability, crying, sedation or sleep problems.
Significant side effects from OTC sleep aids can also result for adults. These problems include headaches, daytime drowsiness, fatigue, dizziness, constipation, vomiting, muscle weakness, nervousness or grogginess.
Consult with your doctor before taking any OTC medication while breastfeeding.
