A06AC55
Forms & Strengths
- Oral powder containing linseed combined with bulk-forming laxatives (e.g., psyllium, senna)
- Granules containing linseed combined with natural laxative ingredients
Adult Dosing
- 1 to 2 spoonfuls (approx. 5 to 10 g) of granules or powder mixed with adequate fluid (at least 150-250 mL water) 1 to 3 times daily
- Must be followed by an additional glass of fluid to prevent esophageal obstruction or fecal impaction
Pediatric Dosing
- Safety and efficacy in children under 12 years are not well established
- Use in pediatric populations generally not recommended without direct medical supervision
Indications
- Treatment of occasional constipation
- Softening of stools in conditions requiring easy defecation (e.g., anal fissures, hemorrhoids)
Mechanism of Action
- Contains high amounts of mucilage and dietary fiber that absorb water in the gastrointestinal tract
- Swells to increase stool volume and stretch the bowel wall, stimulating peristalsis
- Lubricates the intestinal contents to facilitate easier passage
Contraindications
- Hypersensitivity to linseed or combination ingredients
- Gastrointestinal obstruction or fecal impaction
- Sudden changes in bowel habits persisting for more than 2 weeks
- Undiagnosed abdominal pain, nausea, vomiting, or acute surgical abdomen
- Swallowing difficulties or esophageal narrowing
Adverse Reactions
- Abdominal distention, bloating, and flatulence, especially at the start of therapy
- Risk of intestinal or esophageal obstruction if taken with insufficient fluid
- Allergic reactions including rash, pruritus, and anaphylaxis in rare cases
Drug Interactions
- May delay or decrease the gastrointestinal absorption of concurrently administered oral medications (e.g., cardiac glycosides, coumarin anticoagulants, lithium, carbamazepine)
- Should be taken 30 to 60 minutes before or after other medications to minimize absorption interference
