If you are a new mom suffering from infections such as a urinary tract infection or an uncomfortable condition such as constant diarrhea while breastfeeding, you may be quite uneasy. In such scenarios, you may consider taking medications such as Bactrim while breastfeeding. However, you need to talk to your provider before popping a pill during this crucial phase to avoid causing any potential side effects in your breastfeeding baby.

Read on as we tell you the recommended doses, safety aspects, and possible side effects of using Bactrim while breastfeeding.

What Is Bactrim?

Bactrim is an effective medication and combination of antibiotics, namely trimethoprim and sulfamethoxazole, that treat several different kinds of infections that occur due to bacteria. The drug is a combination of one part of a synthetic drug popular as trimethoprim and five parts of sulfonamide drug popular as sulfamethoxazole. The unique combination of antibiotics curbs bacterial growth and cures your bacterial infection (1).

Is It Safe To Take Bactrim While Breastfeeding?

Bactrim easily passes into the breast milk, so you need to exercise caution while using it. When you take the drug, the levels of sulfamethoxazole and trimethoprim in your breast milk increase to approximately 2% to 5 % of the daily recommended dose for infants. So, consult your doctor while going for Bactrim if you are breastfeeding. If your baby has jaundice, is stressed, is ill, or is premature, he is at a high risk of kernicterus and bilirubin displacement. So, avoid taking Bactrim while you are nursing.

Also, you should not take Bactrim if you are suffering from critical kidney or liver ailment, a history of low blood platelets due to trimethoprim, and anemia due to folic acid deficiency. Consult your doctor before you go for the drug while breastfeeding (1).

Nursing mothers should ensure adequate fluid intake and urinary output to prevent the risk of crystalluria while taking Bactrim to treat a UTI.

2. Ear infections

Bactrim helps treat ear infections due to bacteria, such as Haemophilus influenzae and Streptococcus pneumonia. However, lactating mothers should consult the doctor before taking the medication to cure any ear infection (2).

3. Chronic bronchitis

Chronic bronchitis is a bad condition, which only gets worse when it is due to Haemophilus influenzae or Streptococcus pneumonia. However, having an appropriate dose of Bactrim helps you cure this ailment effectively (3).

4. Diarrhea

Bactrim provides nursing moms relief from diarrhea and dysentery due to Shigella sonnei infections, Shigella flexneri, enterotoxigenic E. coli, and traveler’s diarrhea.

5. Pneumonia

Bactrim cures pneumonia that occurs due to Pneumocystis jiroveci. The medication also boosts your immunity considerably.

Side Effects Of Bactrim While Breastfeeding

Even though there are many benefits of having Bactrim, there is always a possibility that you may experience some side-effects of the drug. Here are some common side-effects of the medication.

  • Nausea
  • Vomiting
  • Anorexia or loss of appetite
  • Stomach ache
  • Rash
  • Hives

If you experience any of these side-effects while breastfeeding your infant, stop taking the medication and check with your doctor as soon as possible.

The medication Bactrim is an antibiotic used to treat several bacterial infections. However, a few studies state that the medication might pass through breast milk. Therefore, medical professionals may or may not advise Bactrim while breastfeeding. Consult your doctor if you show any signs of any infections rather than taking the medication by yourself. Follow the doctor’s advice on taking the medications. If you notice any side effects or doubt it affects your nursing, stop its intake and consult your doctor for an alternative medication.
