Inhalation of psyllium dust may cause sensitivity to psyllium (eg, runny nose, watery eyes, wheezing). Drink at least 8 ounces of liquid with each dose. Powder must be mixed in a glass of water or juice. Capsules should be swallowed one at a time. When more than one dose is required, they should be divided throughout the day. Separate dose by at least 2 hours from other drug therapies.
Diabetes mellitus, type 2 (adjunctive therapy) (off-label use): Administer just prior to meals (Abutair 2016; Feinglos 2013).
Irritable bowel syndrome (off-label use): Administer with meals by mixing with food, preferably yogurt (Bijkerk 2009).
Oral: Granules and powder must be mixed in an 8 ounce glass of water or juice; drink an 8 ounce glass of liquid with each dose of wafers or capsules; capsules should be swallowed one at a time. When more than one dose is required, divide throughout the day. Separate dose by at least 2 hours from other drug therapies. Inhalation of psyllium dust may cause sensitivity to psyllium (eg, runny nose, watery eyes, wheezing).
Constipation: Treatment of occasional constipation
Reduce risk of coronary heart disease: To reduce risk of coronary heart disease (CHD)

Hypersensitivity to psyllium or any component of the formulation; fecal impaction; GI obstruction
Concerns related to adverse effects:
• Hypersensitivity reactions: Hypersensitivity reactions have been reported with ingestion or inhalation of psyllium in susceptible individuals.
Disease-related concerns:
• Coronary heart disease (CHD): To reduce the risk of CHD, the soluble fiber from psyllium should be used in conjunction with a diet low in saturated fat and cholesterol.
• Gastrointestinal disease: Use with caution in patients with esophageal strictures, ulcers, stenosis, or intestinal adhesions or difficulty swallowing
Special populations:
• Elderly: Use with caution in the elderly; may have insufficient fluid intake which may predispose them to fecal impaction and bowel obstruction.
Dosage form specific issues:
• Calcium: Some products may contain calcium.
• Phenylalanine: Some products may contain phenylalanine.
• Potassium: Some products may contain potassium.
• Sodium: Some products may contain sodium.
• Soy lecithin: Some products may contain soy lecithin.
Other warnings/precautions:
• Administration: Products must be taken with at least 8 ounces of fluid in order to prevent choking.
• Self-medication (OTC use): When used for self-medication (OTC), do not use in the presence of abdominal pain, nausea, or vomiting. Notify healthcare provider in case of sudden changes of bowel habits which last >2 weeks or in case of rectal bleeding. Not for self-treatment of constipation lasting >1 week.

Psyllium is not absorbed systemically. When administered with adequate fluids, use is considered safe for the treatment of occasional constipation during pregnancy (Wald, 2003).
Products should be taken with at least 8 ounces of fluids. Some products may contain phenylalanine, potassium, sodium, as well as additional ingredients. Check individual product information for caloric and nutritional value.
When used to reduce the risk of CHD, the amount of soluble fiber from psyllium should be ≥7 g/day and it should be used in conjunction with a diet low in saturated fat and cholesterol.
Adequate intake for total fiber: Note: The definition of “fiber” varies; however, the soluble fiber in psyllium is only one type of fiber which makes up the daily recommended intake of total fiber.
1 to 3 years: 19 g/day

Psyllium is a soluble fiber. It absorbs water in the intestine to form a viscous liquid which promotes peristalsis and reduces transit time.
Onset of action: Relief of constipation: 12-72 hours
Absorption: None; small amounts of grain extracts present in the preparation have been reportedly absorbed following colonic hydrolysis
