Below is general information about the safety of the known ingredients contained in the product Psyllium Husks 500 mg. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY SAFE ...when used orally with appropriate fluid intake (93216). Blond psyllium preparations have been safely used in doses up to 20 grams per day for up to 6 months (1376,2324,2327,6261,6262,8060,8061,8066,8423,9422) (10095,13102,22961,22962,22963,22964,22966,54260,22968,22969) (22970,22972,22973,22976,22977,22978,22979,22980,22981,22986) (22987,22988,22989,22990,22992,22993,22994,22995,22996,22998) (23402,23403,23404,23405,92198,106859). The U.S. Food and Drug Administration (FDA) requires over-the-counter medicines that contain dry or incompletely hydrated psyllium to carry a warning that they should be taken with at a least a full glass of liquid to reduce the risk of choking. This labeling also applies to foods containing psyllium that are marketed with a health claim regarding coronary heart disease (93217,93218).
POSSIBLY SAFE ...when used in eye drops. Blond psyllium mucilage has been used with apparent safety in eye drops four times daily for 6 weeks (105274). There is insufficient reliable information available about the safety of blond psyllium when used topically.
LIKELY UNSAFE ...when used orally without adequate fluid intake due to the risk for choking and gastrointestinal obstruction (93218). ...when granular dosage forms containing blond psyllium are used as over the counter (OTC) laxatives. The U.S. Food and Drug Administration (FDA) states that these granular dosage forms are not generally recognized as safe and effective as OTC laxatives due to an increased risk of choking and gastrointestinal obstruction (93219).
CHILDREN: POSSIBLY SAFE
when used orally and appropriately, short-term.
Blond psyllium husk has been used with apparent safety in doses up to 12 grams daily for 4 weeks (110763).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately (272).
LIKELY SAFE ...when used orally and appropriately. Sodium is safe in amounts that do not exceed the Chronic Disease Risk Reduction (CDRR) intake level of 2.3 grams daily (100310). Higher doses can be safely used therapeutically with appropriate medical monitoring (26226,26227).
POSSIBLY UNSAFE ...when used orally in high doses. Tell patients to avoid exceeding the CDRR intake level of 2.3 grams daily (100310). Higher intake can cause hypertension and increase the risk of cardiovascular disease (26229,98176,98177,98178,98181,98183,98184,100310,109395,109396,109398,109399). There is insufficient reliable information available about the safety of sodium when used topically.
CHILDREN: LIKELY SAFE
when used orally and appropriately (26229,100310).
Sodium is safe in amounts that do not exceed the CDRR intake level of 1.2 grams daily for children 1 to 3 years, 1.5 grams daily for children 4 to 8 years, 1.8 grams daily for children 9 to 13 years, and 2.3 grams daily for adolescents (100310).
CHILDREN: POSSIBLY UNSAFE
when used orally in high doses.
Tell patients to avoid prolonged use of doses exceeding the CDRR intake level of 1.2 grams daily for children 1 to 3 years, 1.5 grams daily for children 4 to 8 years, 1.8 grams daily for children 9 to 13 years, and 2.3 grams daily for adolescents (100310). Higher intake can cause hypertension (26229).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately.
Sodium is safe in amounts that do not exceed the CDRR intake level of 2.3 grams daily (100310).
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used orally in higher doses.
Higher intake can cause hypertension (100310). Also, both the highest and the lowest pre-pregnancy sodium quintile intakes are associated with an increased risk of hypertensive disorders of pregnancy, including gestational hypertension and pre-eclampsia, and the delivery of small for gestational age (SGA) infants when compared to the middle intake quintile (106264).
Below is general information about the interactions of the known ingredients contained in the product Psyllium Husks 500 mg. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Theoretically, blond psyllium might reduce the effects of carbamazepine and increase the risk for convulsions.
Details
|
Theoretically, taking blond psyllium at the same time as digoxin might reduce digoxin absorption.
Details
|
Theoretically, taking blond psyllium at the same time as ethinyl estradiol might alter levels of estradiol.
Details
Concurrent use of blond psyllium with ethinyl estradiol results in a slight increase in the extent of ethinyl estradiol absorption and a slower rate of absorption. However, this is unlikely to be clinically significant (12421).
|
Theoretically, taking blond psyllium at the same time as lithium might reduce lithium absorption.
Details
|
Theoretically, blond psyllium might increase the therapeutic and adverse effects of metformin.
Details
Concurrent use of blond psyllium with metformin slows and increases metformin absorption (99433). To avoid changes in absorption, take psyllium 30-60 minutes after metformin.
|
Theoretically, taking blond psyllium at the same time as olanzapine might reduce olanzapine absorption.
Details
The fiber in blond psyllium might decrease the absorption of olanzapine. A single case report describes a reduction in the effectiveness of olanzapine when it was taken concomitantly with an unspecified type of psyllium 3 grams orally twice daily. This effect was reversed when psyllium was stopped (106858).
|
Theoretically, psyllium might increase, decrease, or have no effect on the absorption of oral drugs.
Details
Psyllium seems to have variable effects on drug absorption. To avoid changes in absorption, take psyllium 30-60 minutes after oral medications. Animal research shows that blond psyllium delays and increases the absorption of metformin and ethinyl estradiol (12421,99433). Conversely, case reports and animal research suggest that blond psyllium might reduce absorption of lithium, digoxin, olanzapine, and carbamazepine (12,18,272,93214,106858). Finally, some pharmacokinetic studies show that psyllium does not affect the absorption of levothyroxine or warfarin (12420,103940).
|
Theoretically, a high intake of dietary sodium might reduce the effectiveness of antihypertensive drugs.
Details
|
Concomitant use of mineralocorticoids and some glucocorticoids with sodium supplements might increase the risk of hypernatremia.
Details
Mineralocorticoids and some glucocorticoids (corticosteroids) cause sodium retention. This effect is dose-related and depends on mineralocorticoid potency. It is most common with hydrocortisone, cortisone, and fludrocortisone, followed by prednisone and prednisolone (4425).
|
Altering dietary intake of sodium might alter the levels and clinical effects of lithium.
Details
High sodium intake can reduce plasma concentrations of lithium by increasing lithium excretion (26225). Reducing sodium intake can significantly increase plasma concentrations of lithium and cause lithium toxicity in patients being treated with lithium carbonate (26224,26225). Stabilizing sodium intake is shown to reduce the percentage of patients with lithium level fluctuations above 0.8 mEq/L (112909). Patients taking lithium should avoid significant alterations in their dietary intake of sodium.
|
Concomitant use of sodium-containing drugs with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia and long-term sodium-related complications.
Details
The Chronic Disease Risk Reduction (CDRR) intake level of 2.3 grams of sodium daily indicates the intake at which it is believed that chronic disease risk increases for the apparently healthy population (100310). Some medications contain high quantities of sodium. When used in conjunction with sodium supplements or high-sodium diets, the CDRR may be exceeded. Additionally, concomitant use may increase the risk for hypernatremia; this risk is highest in the elderly and people with other risk factors for electrolyte disturbances.
|
Theoretically, concomitant use of tolvaptan with sodium might increase the risk of hypernatremia.
Details
Tolvaptan is a vasopressin receptor 2 antagonist that is used to increase sodium levels in patients with hyponatremia (29406). Patients taking tolvaptan should use caution with the use of sodium salts such as sodium chloride.

Below is general information about the adverse effects of the known ingredients contained in the product Psyllium Husks 500 mg. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally, blond psyllium is generally well tolerated.
When used as eye drops, blond psyllium seems to be well tolerated.
Most Common Adverse Effects:
Oral: Abdominal pain, constipation, diarrhea, dyspepsia, flatulence, and nausea.
Serious Adverse Effects (Rare):
Oral: Bowel obstruction, esophageal obstruction.
Gastrointestinal ...Orally, blond psyllium can cause transient flatulence, abdominal pain, diarrhea, constipation, dyspepsia, and nausea (1376). Starting with a low dose and slowly titrating to the desired dose can often minimize gastrointestinal side effects. There is some concern that blond psyllium can cause esophageal or bowel obstruction when consumed without water or in patients with swallowing disorders (604,8080,8081,110760). Tell patients to consume plenty of water when taking blond psyllium. Suggest at least 240 mL of fluid for every 3.5-5 grams of seed husk or 7 grams of seed (1376,8080,8081).
Musculoskeletal ...Orally, backache has been reported with the use of psyllium (1376).
Neurologic/CNS ...Orally, headache has been reported with the use of psyllium (1376).
Ocular/Otic ...Ophthalmically, blurred vision or burning haven been reported rarely in patients using eye drops containing blond psyllium mucilage (105274).
Pulmonary/Respiratory ...Orally, rhinitis, increased cough, and sinusitis have been reported with the use of psyllium (1376).
Other
...Some patients can have an allergic response to blond psyllium.
Allergy symptoms include allergic rhinitis, sneezing, conjunctivitis, urticarial rash, itching, flushing, and dyspnea. More serious symptoms include wheezing, facial and body swelling, chest congestion, chest and throat tightness, cough, diarrhea, hypotension, loss of consciousness, and anaphylactic shock. Occupational exposure or repeated ingestion of psyllium can cause sensitization, which can lead to serious allergic reactions (2328,2329,2330,8079,9246,92193). Severe allergic reactions may occur after eating a small quantity of cereal that contains blond psyllium. At least one cereal (Heartwise, Kellogg Co.) has increased the purity of the psyllium it contains, which has decreased the incidence of allergic reactions (9244). A warning of the potential for allergic reactions is on the label of all cereals that contain psyllium (9247). Patients hypersensitive to psyllium usually have marked eosinophilia and an elevated psyllium-specific IgE antibody serum level (2328,2329,92193).
There is concern that individuals allergic to pollen from English plantain weed (Plantain lanceolate) might also react to psyllium husk dust; however, it appears that there is little cross-allergenicity between these plants and is probably mild and of no clinical significance (8057,9244,92193).
Blond psyllium has a tendency to plug feeding tubes. This can be avoided if blond psyllium is mixed with water and pushed through the feeding tube in less than 5 minutes (8423).
General
...Orally, sodium is well tolerated when used in moderation at intakes up to the Chronic Disease Risk Reduction (CDRR) intake level.
Topically, a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: Worsened cardiovascular disease, hypertension, kidney disease.
Cardiovascular
...Orally, intake of sodium above the CDRR intake level can exacerbate hypertension and hypertension-related cardiovascular disease (CVD) (26229,98176,100310,106263).
A meta-analysis of observational research has found a linear association between increased sodium intake and increased hypertension risk (109398). Observational research has also found an association between increased sodium salt intake and increased risk of CVD, mortality, and cardiovascular mortality (98177,98178,98181,98183,98184,109395,109396,109399). However, the existing research is unable to confirm a causal relationship between sodium intake and increased cardiovascular morbidity and mortality; high-quality, prospective research is needed to clarify this relationship (100312). As there is no known benefit with increased salt intake that would outweigh the potential increased risk of CVD, advise patients to limit salt intake to no more than the CDRR intake level (100310).
A reduction in sodium intake can lower systolic blood pressure by a small amount in most individuals, and diastolic blood pressure in patients with hypertension (100310,100311,106261). However, post hoc analysis of a small crossover clinical study in White patients suggests that 24-hour blood pressure variability is not affected by high-salt intake compared with low-salt intake (112910). Additionally, the available research is insufficient to confirm that a further reduction in sodium intake below the CDRR intake level will lower the risk for chronic disease (100310,100311). A meta-analysis of clinical research shows that reducing sodium intake increases levels of total cholesterol and triglycerides, but not low-density lipoprotein (LDL) cholesterol, by a small amount (106261).
It is unclear whether there are safety concerns when sodium is consumed in amounts lower than the adequate intake (AI) levels. Some observational research has found that the lowest levels of sodium intake might be associated with increased risk of death and cardiovascular events (98181,98183). However, this finding has been criticized because some of the studies used inaccurate measures of sodium intake, such as the Kawasaki formula (98177,98178,101259). Some observational research has found that sodium intake based on a single 24-hour urinary measurement is inversely correlated with all-cause mortality (106260). The National Academies Consensus Study Report states that there is insufficient evidence from observational studies to conclude that there are harmful effects from low sodium intake (100310).
Endocrine ...Orally, a meta-analysis of observational research has found that higher sodium intake is associated with an average increase in body mass index (BMI) of 1. 24 kg/m2 and an approximate 5 cm increase in waist circumference (98182). It has been hypothesized that the increase in BMI is related to an increased thirst, resulting in an increased intake of sugary beverages and/or consumption of foods that are high in salt and also high in fat and energy (98182). One large observational study has found that the highest sodium intake is not associated with overweight or obesity when compared to the lowest intake in adolescents aged 12-19 years when intake of energy and sugar-sweetened beverages are considered (106265). However, in children aged 6-11 years, usual sodium intake is positively associated with increased weight and central obesity independently of the intake of energy and/or sugar-sweetened beverages (106265).
Gastrointestinal ...In one case report, severe gastritis and a deep antral ulcer occurred in a patient who consumed 16 grams of sodium chloride in one sitting (25759). Chronic use of high to moderately high amounts of sodium chloride has been associated with an increased risk of gastric cancer (29405).
Musculoskeletal
...Observational research has found that low sodium levels can increase the risk for osteoporosis.
One study has found that low plasma sodium levels are associated with an increased risk for osteoporosis. Low levels, which are typically caused by certain disease states or chronic medications, are associated with a more than 2-fold increased odds for osteoporosis and bone fractures (101260).
Conversely, in healthy males on forced bed rest, a high intake of sodium chloride (7.7 mEq/kg daily) seems to exacerbate disuse-induced bone and muscle loss (25760,25761).
Oncologic ...Population research has found that high or moderately high intake of sodium chloride is associated with an increased risk of gastric cancer when compared with low sodium chloride intake (29405). Other population research in patients with gastric cancer has found that a high intake of sodium is associated with an approximate 65% increased risk of gastric cancer mortality when compared with a low intake. When zinc intake is taken into consideration, the increased risk of mortality only occurred in those with low zinc intake, but the risk was increased to approximately 2-fold in this sub-population (109400).
Pulmonary/Respiratory ...In patients with hypertension, population research has found that sodium excretion is modestly and positively associated with having moderate or severe obstructive sleep apnea. This association was not found in normotensive patients (106262).
Renal ...Increased sodium intake has been associated with impaired kidney function in healthy adults. This effect seems to be independent of blood pressure. Observational research has found that a high salt intake over approximately 5 years is associated with a 29% increased risk of developing impaired kidney function when compared with a lower salt intake. In this study, high salt intake was about 2-fold higher than low salt intake (101261).
