Triticum (wheat fibre, ATC A06AC07) is a bulk‑forming laxative of plant origin that is considered compatible with breastfeeding when used in usual oral doses and with adequate fluid intake.medpedia.framar+2

Monograph title and ATC classification

Title: Triticum (wheat fibre) – bulk‑forming laxative (ATC A06AC07) in breastfeeding

Triticum (wheat fibre) is classified in the ATC system under A06A “Drugs for constipation”, subgroup A06AC “Bulk‑forming laxatives”, specific code A06AC07 “triticum (wheat fibre)”.atcddd.fhi+2
It is a medicinal product of plant origin, derived from the outer layers of wheat grain (wheat bran/fibre), and exerts a laxative effect through its high content of insoluble dietary fibre.pmc.ncbi.nlm.nih+3

Pharmacology and mechanism of action

Wheat fibre consists predominantly of insoluble polysaccharides (cellulose, hemicellulose, lignin) that resist digestion in the small intestine and reach the colon largely unchanged.webmd+2
By binding water and increasing stool bulk, it mechanically stimulates colonic motility, normalises transit time, and facilitates defecation in patients with constipation and difficult stool passage.rxlist+2

The onset of action is gradual (often within 24–72 hours) and depends on sufficient fluid intake and dietary habits.breastfeeding-and-medication+2
Systemic absorption of wheat fibre is negligible; it acts locally in the gastrointestinal tract and is not expected to reach clinically relevant plasma levels.breastfeedingnetwork+2

Therapeutic indications

According to the Bulgarian pharmacological description, triticum (wheat fibre) is indicated in patients with constipation and in those with difficult defecation.medpedia.framar
It is also used in conditions where soft stool consistency is desirable, such as haemorrhoids, anal fissures, and inflammatory diseases affecting the rectum.medpedia.framar

More broadly, wheat bran/fibre is used as a source of dietary fibre for prevention and treatment of mild constipation, for functional bowel disorders such as irritable bowel syndrome, and to improve stool regularity.webmd+1
In breastfeeding women, bulk‑forming laxatives (including wheat or oat bran) are recommended as first‑line pharmacological options when lifestyle and diet measures are insufficient.breastfeeding-and-medication+1

Dosage and administration

The ATC/DDD index assigns a defined daily dose (DDD) of 10 g for triticum (wheat fibre) as a bulk‑forming laxative in adults.atcddd.fhi
Clinical sources on wheat bran as medicine describe typical oral doses of about 20–30 g per day for constipation or functional bowel disorders, taken with plenty of water and titrated according to individual tolerance.rxlist+1

Doses should be started low and increased gradually to minimise flatulence and abdominal discomfort, while ensuring adequate fluid intake to avoid intestinal obstruction.breastfeeding-and-medication+2
In lactating women, the lowest effective dose is preferred, with reassessment if symptoms do not improve after several days or if adverse effects occur.breastfeedingnetwork+1

Contraindications and cautions

The local monograph states that triticum (wheat fibre) must not be used in patients with hypersensitivity to the product or its components.medpedia.framar
Additional contraindications for bulk fibre laxatives, though not listed on the Framar page, generally include: known or suspected intestinal obstruction, stenosis, and severe faecal impaction, where increased bulk may worsen blockage.breastfeedingnetwork+1

Patients with celiac disease or non‑celiac wheat allergy should avoid wheat‑derived fibre and use alternative bulk‑forming agents such as psyllium or methylcellulose.encyclopedia+2
As with all laxatives, persistent constipation, unexplained abdominal pain, rectal bleeding, or unintended weight loss warrant medical evaluation rather than prolonged self‑treatment.breastfeeding-and-medication+1

Interactions

The Framar interaction database lists moderate and minor clinically significant interactions for triticum (wheat fibre), with 2 moderate and 22 minor entries, without detail in the public summary.medpedia.framar
In general, bulk‑forming fibres can reduce the absorption of concomitantly administered oral medicines (for example, some cardiac glycosides and other narrow‑therapeutic‑index drugs) if taken at the same time.rxlist

A practical recommendation is to administer other oral medicines at least 1–2 hours before or after wheat fibre preparations to minimise potential reduction in bioavailability.breastfeedingnetwork+2
Patients on multiple chronic medications should consult a healthcare professional to individualise timing and monitor for reduced efficacy of concurrent treatments.breastfeeding-and-medication+1

Adverse effects and toxicity

Wheat fibre is generally well tolerated; the most common adverse effects are gastrointestinal and include flatulence, bloating, and mild abdominal discomfort, particularly in the first days of therapy.webmd+1
Excessive intake without adequate fluid can increase the risk of intestinal or oesophageal obstruction, especially in patients with pre‑existing anatomical narrowing or impaired motility.breastfeedingnetwork+1

Systemic toxicity is not expected because the product is not absorbed and acts locally as a mechanical bulk‑forming agent.webmd+2
Long‑term use at high doses may cause dependence on laxatives or mask underlying pathology, so regular reassessment of the need for continued therapy is advisable.breastfeeding-and-medication+1

Allergic reactions to wheat components (cutaneous or respiratory symptoms, or exacerbation of celiac disease) are rare but possible and require discontinuation and alternative fibre sources.pmc.ncbi.nlm.nih+2
In overdose, symptoms are usually limited to pronounced bloating, abdominal cramps, and constipation or, paradoxically, impaction; management is supportive with hydration and, if needed, medical intervention.breastfeedingnetwork+1

Use during pregnancy and lactation

Authoritative consumer and supplement monographs state that wheat bran is likely safe when taken orally during pregnancy and breastfeeding, within usual dietary or medicinal doses.rxlist+1
Professional breastfeeding resources emphasise that bulk‑forming laxatives are minimally absorbed and can be used during breastfeeding, with osmotic or bulk agents preferred over stimulant laxatives when medication is required.breastfeeding-and-medication+1

Because triticum (wheat fibre) acts locally in the gut and is not systemically absorbed to a significant extent, transfer into breast milk is not expected, and clinically relevant exposure of the breastfed infant is unlikely.webmd+2
No specific adverse effects in breastfed infants have been reported in association with maternal intake of wheat bran or wheat fibre within recommended doses.rxlist+2

General dietary literature on breastfeeding recommends adequate intake of whole grains and high‑fibre foods as part of a healthy maternal diet, which indirectly supports regular bowel function without compromising lactation.edepot.wur+2
As with other laxatives in lactation, triticum (wheat fibre) should be used for the shortest effective duration, with preference for non‑pharmacological measures (diet, fluids, physical activity) as first‑line interventions.clevelandclinic+2

Lactation safety assessment

From a toxico‑lactological perspective, triticum (wheat fibre, A06AC07) can be classified as compatible with breastfeeding when used at therapeutic doses as a bulk‑forming laxative.webmd+3
The lack of systemic absorption, absence of evidence for transfer into milk, and long experience with wheat bran in pregnancy and lactation support a favourable safety profile for nursing mothers and infants.rxlist+2

Potential concerns relate mainly to maternal tolerability (gas, bloating) and to gluten or wheat allergy in the mother rather than direct toxic effects on the infant.encyclopedia+3
Routine monitoring of maternal symptoms and infant wellbeing (stool pattern, feeding, behaviour) is advisable, as with any maternal medication or supplement, but specific restrictions on breastfeeding are not required.breastfeedingnetwork+1

Practical lactation recommendations

·        Use the lowest effective oral dose, with sufficient water intake (at least one large glass of water with each dose).webmd+2

·        Avoid use in mothers with celiac disease or known wheat allergy; choose an alternative bulk‑forming agent in such cases.pmc.ncbi.nlm.nih+2

·        Separate administration of wheat fibre from critical oral medications by at least 1–2 hours.rxlist+2

·        Encourage concurrent non‑pharmacological measures: fibre‑rich diet, adequate fluids, and physical activity, tailored to the postpartum situation.clevelandclinic+2
