When breastfeeding healthy, full-term infants, metronidazole at regular doses is deemed safe. There is no proven mutagenic or carcinogenic risk to infants breastfeeding from mothers getting standard short-course metronidazole treatment by any route, according to the balance of existing evidence and clinical experience, as well as the consensus of expert opinion.

Oral metronidazole at a low dose of 200-400 mg three times a day yields milk levels that are only slightly lower than those found in maternal plasma (76 to 99 percent). However, dosages up to 500 mg daily for around 8 days course can be regarded as good for breastfeeding mothers.

Single-dose oral metronidazole at a dose of 2 g results in much higher amounts of metronidazole in milk than low-dose oral treatment. The predicted total consumption, on the other hand, is still less than the daily baby dose administered directly. Breastfeeding is thought to be suitable with daily 2 g oral dosages administered for three days.

Although the data is limited, intravenous treatment provides identical maternal plasma and milk levels to corresponding oral doses. Breastfeeding is thought to be suitable with short-course IV metronidazole.

Premature breastfed newborns (t1/2 up to 74 hours) and infants with low birth weight or renal or hepatic impairment should avoid metronidazole exposure. Give the mother an alternative antibiotic if possible; otherwise, use heated donor milk (if available) or milk powder, and reject expressed milk throughout the metronidazole treatment.

Experts debate on whether or not it is safe to use metronidazole during longer-term medication while breastfeeding, however, some sources advise halting breastfeeding for 12 to 24 hours following a single-dose maternal treatment. For some of the illnesses that metronidazole is used to treat, other medicines are available. Although the seller of one vaginal product recommends against breastfeeding during treatment and for two days following the final dose, topical or vaginal metronidazole usage during breastfeeding is unlikely to be of issue.

Why Should I Wait to Breastfeed After Taking Metronidozole?

Metronidazole is found in substantial levels in breast milk. The amount found in breastmilk, however, is less than the level used to treat small infants who tolerated the medicine. With vaginal or topical use, the amounts in breast milk would be reduced. A nursing infant may develop loose stools if metronidazole is administered during breastfeeding, especially if the medicine is administered directly into a vein (intravenously) to the person who is breastfeeding. A yeast infection in some newborns is possible (diaper rash or thrush). Although there have also been reports of breastfed newborns who have had no adverse effects.

Oral

Metronidazole is excreted in breast milk when taken orally. If your doctor wishes to give this drug for oral administration, tell them you’re breastfeeding. It is not recommended due to negative effects observed in breastfeeding infants whose moms are taking this medication. If you need oral metronidazole and breastfeeding is your only choice, the Centers for Disease Control and Prevention (CDC) recommends that you discontinue breastfeeding for 24 hours. During this time, you’ll need to supplement your diet with formula. Your doctor may prescribe the medication in a single dose, after which you can begin nursing 24 hours later.

Intravenous

If you have a serious infection, your doctor may prescribe metronidazole intravenously. This will allow the drug to enter your bloodstream directly. Because of the amount that may enter into breast milk while on the IV form of this drug, breastfeeding is not recommended.

Vaginal Gel

If your doctor prescribes metronidazole vaginal gel, tell them you’re breastfeeding. According to research, the topical gel is not as well absorbed as the oral form. The majority of doctors and pharmacists believe that this method is safe. When deciding what to do, though, follow your doctor’s advice. Breastfeeding should also be stopped until 24 hours following your final dose of this drug, according to the literature. You will need to utilize supplemental formula during therapy if you choose this option.

For a variety of illnesses, including pelvic inflammatory disease, metronidazole tablets, liquid, and suppositories are recommended. The sort of infection, the dose, and the length of time you’ll need to take the medicine are all determined by the type of infection and its severity.

Some infections can be treated with just one pill, while others require a two-week course of antibiotics. When using metronidazole cream or gel while breastfeeding, use caution. Make sure you don’t get it on your breasts by accident. If this occurs, make sure to wash any cream or gel from your breasts before feeding your baby.
