Breastfeeding & OTC Medication: Safety Tips That You Need To Know

Medically reviewed on Aug 08, 2016 by L. Anderson, PharmD

New Mother? Breastfeeding is Best.

Did you recently have a new bundle of joy? Congratulations! If you are like many new moms, you may be new to nursing, too. You know that breastfeeding is the best way to feed your baby. But let's face it: headaches and sore muscles will still happen, coughs and colds will come and go, and you may need to take any myriad of meds, even while you're nursing.

Although many over-the-counter (OTC) drugs are safe to use while breastfeeding, some will get into your milk to a degree and may even affect your milk supply. Here are a few answers about common OTC medicines and breastfeeding to help keep you and your baby on the right track.

What Are the Important Questions?

There are many issues to consider for medication use during breastfeeding. Questions you may want to address with your doctor include: How helpful will the drug be to you and your illness? Is there a risk the baby will stop nursing, even temporarily? How safe is the medicine if consumed by the baby through breast milk?

When you are sick or in need of medication, you may not feel like talking to your doctor for any length of time. So it may be wise to ask questions about common OTC medicines you might take - acetaminophen, ibuprofen, allergy medicines, OTC cold products, and medicines for constipation - before illness strikes.

Is There a Best Time to Take A Medication?

If possible, take medications that are given only once a day right after a feeding when your baby will have the longest period without nursing; for many women this is the last feeding of the night before the infant's bedtime. Your doctor and pediatrician are always the best resource for questions regarding timing of drug use during breastfeeding.

Search or browse the Drugs.com database for guidelines on taking individual medicines while breastfeeding. Answers for many common drugs are posted here, too.

What About OTC Meds: Ibuprofen

Ibuprofen (Motrin, Advil) is a common medicine for many new moms, with headaches, backaches, and muscle soreness happening almost daily. Because of its extremely low levels in breast milk, short half-life and use in infants in doses much higher than those excreted in breast milk, ibuprofen is one preferred choice as an analgesic or anti-inflammatory agent in nursing mothers.

According to the LactMed database from the National Library of Medicine, at least 23 cases are reported in the literature in which infants (ages not stated) were breastfed during maternal ibuprofen use with no adverse effects reported.

The Go-To Med: Acetaminophen

While acetaminophen may not work as well as ibuprofen for pain due to inflammation, acetaminophen is probably the OTC of choice - especially when you have a pounding headache, non-inflammatory pain or need to quiet a fever.

Plus, acetaminophen is given to infants as a fever and pain reliever, too, so there's a good level of comfort with using it during breastfeeding. Amounts in milk are much less than doses usually given to infants. Adverse effects in breastfed infants appear to be rare. Reports that acetaminophen can cause asthma in infants is not backed up by reliable data.

Avoid Aspirin in Most Cases

For headaches and minor pains, acetaminophen or ibuprofen are usually the first choice while nursing. Experts state that aspirin is best avoided during breastfeeding; however, some opinion indicates that low-dose (75 to 162 mg daily) aspirin may be considered as a blood-thinning agent for use in breastfeeding women if required. It is recommended to avoid high-dose aspirin.

Check with your doctor before taking any aspirin while nursing. If low-dose aspirin is recommended by your doctor, avoid breastfeeding for 1 to 2 hours after a dose to minimize blood-thinning effects in the infant. An alternate drug is preferred over continuous high-dose, aspirin therapy.

Non-Drowsy Antihistamines

Spring can wreak havoc for new moms with allergies, and there simply is no time for stuffiness and antihistamine drowsiness with a new baby. Loratadine (Claritin) or fexofenadine (Allegra) are non-drowsy OTC antihistamines used to relieve symptoms of sneezing, itching, watery eyes, and runny nose.

Because of low (or no) sedation and low milk levels, using the lowest dose possible of loratadine or fexofenadine for allergy symptoms would not be expected to cause side effects in infants. You may want to avoid Allegra-D or Claritin-D, as the combination with the decongestant pseudoephedrine might slow down milk production.

Liquid Antacids

Heartburn (dyspepsia) can be a common problem for new moms. Lack of sleep, a hurried eating schedule, coupled with a baby on your belly, can often be to blame. But in usual doses, most antacids are safe while nursing.

Minerals used in antacids, like calcium, magnesium, and aluminum, are also found in human milk. Plus, oral absorption of magnesium and aluminum are poor. Common products include Tums, Maalox, Mylanta, Gaviscon, Mylicon, or their generics.

Antacids may also contain alginic acid or simethicone (for gas), but these are not absorbed orally. Experts generally consider antacid use at normal doses during breastfeeding to be acceptable with no special precautions.

OTC Oral Tablets for Heartburn

Sometimes the heartburn for a new mom needs a little more than an antacid. Many women use oral tablets like over-the-counter (OTC) famotidine (Pepcid AC) or ranitidine (Zantac 150) before pregnancy. For acid indigestion, these agents appear to also be safe while nursing.

The doses of famotidine or ranitidine in breast milk is less than the dose used in newborn infants. The usual dose of famotidine or ranitidine that the mother would take would not be expected to cause any side effects in the breastfed baby. No special precautions are required with these drugs, although follow dosing recommendations.

Caffeine (please)

A Cup 'O Joe may be needed for many new moms, but caffeine is a stimulant to the newborn, too. There's no way to get around it. Caffeine appears in breast milk rapidly after the mom consumes it. Fussiness, jitteriness and poor sleep patterns have been reported in the infants of mothers with very high caffeine intakes equivalent to about 10 or more cups of coffee daily.

Experts suggest no more than 300 mg per day (roughly 2 to 3 eight ounce cups of coffee). It's best to avoid highly concentrated energy drinks, multiple espressos, or caffeine tablets. Mothers of preterm babies should avoid caffeine or consume lower levels. Find more information about caffeine content levels here.

Decongestant Nasal Sprays

A clogged-up nose is no fun when you are trying to cuddle your new baby. Over-the-counter (OTC) nasal spray decongestants used to treat stuffy noses are recommended over oral decongestants like pseudoephedrine or phenylephrine, which can decrease milk production.

The spray products, which may contain nasal oxymetazoline or phenylephrine (Afrin, Neo-Synephrine, Dristan) have limited absorption into the blood stream, as they act locally on the nose. Use nasal decongestant sprays only for 3 days on and then 3 days off, as you can develop rebound congestion. A nasal saline spray or a Neti Pot is safe if you prefer.

Laxatives for Constipation

Most new moms will tell you that constipation is a common occurrence after pregnancy. Dehydration may contribute to this problem, as well as higher levels of the hormone progesterone, a slowed digestive tract, or use of constipating pain relievers.

In the days right after having a baby, get back to a normal diet, keep moving around, drink lots of water and eat high-fiber foods to keep your bowels moving. If needed, and as directed by your doctor, bulk-forming and stool softener laxatives like psyllium (Metamucil) or docusate (Colace) may be the preferred stool softeners of choice.

Yeast Infections

Yeast infections that occur on the breasts lead to sore breasts and swollen nipples. Breasts may turn pink or shiny and itch. The baby can develop diaper rash or thrush in the mouth, too, that may appear as white spots. The yeast infection feeds on the milk left on the breast.

Miconazole cream, an antifungal, does not absorb into the bloodstream very well and is unlikely to cause problems in the breastfed infant. However, you should visit your doctor to determine if a breast yeast infection is present, as miconazole may not be needed. Only use water-soluble creams or gels products on the breast; ointments may expose the infant to paraffins.

Where Else Can I Find Reliable Information?

Other accurate sources of information to aid you and your doctor about medications in breastfeeding are the online LactMed Database, a free and searchable database of drugs and other chemicals to which nursing mothers may be exposed. It includes both OTC and prescription drugs.

The levels of substances in breast milk and infant blood, and the possible adverse effects in the nursing infant are also outlined, if known. Suggested therapeutic alternatives to those drugs are provided, where appropriate. All data are derived from the scientific literature.
