| drug name | Bulk-forming Laxatives |
| classification | Laxatives (Stimulant-Free) |
| pharmacokinetics | Bulk-forming laxatives work by increasing the volume of stool in the intestines. They absorb water, creating a larger, softer stool that's easier to pass. The exact absorption and excretion pathways vary depending on the specific fiber type (e.g., psyllium, methylcellulose). There is no significant first-pass metabolism. Excretion is primarily via the feces. |
| suggested dosage | Dosage varies significantly based on the specific product and the patient's needs. Consult the product label and a healthcare professional for appropriate dosage recommendations. Common starting ranges typically fall between 1-2 teaspoons (5-10 grams) of powder or 1-2 tablets mixed with 8-12 oz of liquid daily. |
| indications | Bulk-forming laxatives are primarily used for the relief of occasional constipation, preventing constipation, and for managing conditions like irritable bowel syndrome (IBS) with constipation. They are often preferred over stimulant laxatives for long-term use due to a generally milder effect and lower risk of side effects. |
| safety in pregnancy | Generally considered safe during pregnancy when used as directed by a healthcare provider. However, consult with a doctor before using any laxative during pregnancy. Do not self-treat. |
| safety in breastfeeding | Generally considered safe for use during breastfeeding when used as directed by a healthcare provider. However, consult with a doctor before using any laxative during breastfeeding. |

| interactions | | 1 | Certain medications, like some calcium supplements, can decrease the effectiveness of bulk-forming laxatives.

Avoid taking concurrently with medications that decrease gastric motility |
|
