Safe Treatment Options for IBS in Breastfeeding Mothers
Soluble fiber, certain antispasmodics, and probiotics are the safest first-line treatments for IBS in breastfeeding mothers, while loperamide can be used cautiously for IBS with diarrhea. 1, 2
First-Line Treatments
Dietary and Lifestyle Modifications
- Regular exercise should be recommended to all breastfeeding mothers with IBS as it helps manage symptoms 1, 2
- First-line dietary advice should include soluble fiber supplementation, such as ispaghula (psyllium), starting at a low dose of 3-4g/day and gradually increasing to avoid bloating 1
- Insoluble fiber (e.g., wheat bran) should be avoided as it may exacerbate symptoms 1
- A low-FODMAP diet may be considered as a second-line dietary therapy but should be implemented under the supervision of a trained dietitian 1, 2
Medication Options
- Loperamide is considered safe during breastfeeding by the American Academy of Pediatrics (AAP) and may be used for IBS with diarrhea, but should be titrated carefully to avoid side effects like abdominal pain, bloating, and constipation 1, 3
- Certain antispasmodics may be effective for abdominal pain in IBS, though patients should be counseled about potential side effects such as dry mouth, visual disturbance, and dizziness 1
- Probiotics as a group may help with global symptoms and abdominal pain, though no specific strain can be recommended; a 12-week trial is reasonable 1, 2
Second-Line Treatments
For Persistent Symptoms
- Tricyclic antidepressants (TCAs) used as gut-brain neuromodulators can be considered for refractory symptoms, starting at a low dose (e.g., 10 mg amitriptyline once daily) and titrating slowly to a maximum of 30-50 mg once daily 1
- Selective serotonin reuptake inhibitors (SSRIs) may be an alternative to TCAs for global symptom management in breastfeeding mothers who cannot tolerate TCAs 1
Subtype-Specific Treatments
- For IBS with constipation: Soluble fiber supplementation is particularly beneficial 2
- For IBS with diarrhea: Loperamide may be used cautiously with careful dose titration 1, 3
Medications to Avoid During Breastfeeding
- Methotrexate is absolutely contraindicated during breastfeeding 4
- Ciprofloxacin and metronidazole should be avoided during breastfeeding if possible 4
- Eluxadoline, a mixed opioid receptor drug for IBS-D, has limited safety data in breastfeeding and should be avoided 5
- 5-HT3 receptor antagonists like alosetron have insufficient safety data for breastfeeding and should be avoided 6, 5
Monitoring and Follow-up
- Mental health screening should be performed with appropriate referral to support services, given the increased burden of mental health issues during pregnancy and postpartum 2
- Stool cultures should be obtained for enteroinvasive bacterial infections and Clostridioides difficile testing if symptoms worsen, to rule out other causes 7
- Careful review of travel and contact history should be taken, with appropriate testing for infectious causes in patients with worsening symptoms 2
Important Considerations
- Medicines that are low risk in pregnancy are generally also low risk in breastfeeding and can be continued 1
- Breastfeeding is the preferred method of feeding and does not affect the course of IBD or IBS 1, 8
- Most breastfeeding women with IBD discontinue medications due to safety concerns, but this is often unnecessary and may lead to disease flares 8
- Dedicated clinics can greatly support mothers during breastfeeding periods to enhance knowledge, optimize medication adherence, and improve outcomes 8
Remember that the goal of treatment is to manage symptoms while ensuring the safety of both mother and infant, with a focus on treatments that have established safety profiles during breastfeeding.
