Below is general information about the safety of the known ingredients contained in the product Daily Psyllium Fiber. 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, short-term (12,272). Black psyllium has been used with apparent safety in doses of 15-30 grams daily for up to 6 months (19156,10091,93215,102826). 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 claim of reducing the risk of coronary heart disease (93217,93218).
LIKELY UNSAFE ...when black psyllium is used orally without adequate fluid intake due to the risk for choking and gastrointestinal obstruction (2,18,93218). ...when granular dosage forms containing black 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 (GRASE) as OTC laxatives due to an increased risk of choking and gastrointestinal obstruction (93219).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally with appropriate fluid intake (272).
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. For people age 14 and older with adequate iron stores, iron supplements are safe when used in doses below the tolerable upper intake level (UL) of 45 mg per day of elemental iron. The UL is not meant to apply to those who receive iron under medical supervision (7135,96621). To treat iron deficiency, most people can safely take up to 300 mg elemental iron per day (15). ...when used intravenously and appropriately. Ferric carboxymaltose 200 mg and iron sucrose 200 mg have been given intravenously for up to 10 doses with no reported serious adverse effects (91179). A meta-analysis of clinical studies of hemodialysis patients shows that administering high-dose intravenous (IV) iron does not increase the risk of hospitalization, infection, cardiovascular events, or death when compared with low-dose IV iron, oral iron, or no iron treatment (102861). A more recent meta-analysis of clinical studies of all patient populations shows that administering IV iron does not increase the risk of hospital length of stay or mortality, although the risk of infection is increased by 16% when compared with oral iron or no iron (110186). Despite these findings, there are rare reports of hypophosphatemia and/or osteomalacia (112603,112608,112609,112610).
LIKELY UNSAFE ...when used orally in excessive doses. Doses of 30 mg/kg are associated with acute toxicity. Long-term use of high doses of iron can cause hemosiderosis and multiple organ damage. The estimated lethal dose of iron is 180-300 mg/kg; however, doses as low as 60 mg/kg have also been lethal (15).
CHILDREN: LIKELY SAFE
when used orally and appropriately (7135,91183,112601).
CHILDREN: LIKELY UNSAFE
when used orally in excessive amounts.
Tell patients who are not iron-deficient not to use doses above the tolerable upper intake level (UL) of 40 mg per day of elemental iron for infants and children. Higher doses frequently cause gastrointestinal side effects such as constipation and nausea (7135,20097). Iron is the most common cause of pediatric poisoning deaths. Doses as low as 60 mg/kg can be fatal (15).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately.
Iron is safe during pregnancy and breast-feeding in patients with adequate iron stores when used in doses below the tolerable upper intake level (UL) of 45 mg daily of elemental iron (7135,96625,110180).
PREGNANCY AND LACTATION: LIKELY UNSAFE
when used orally in high doses.
Tell patients who are not iron deficient to avoid exceeding the tolerable upper intake level (UL) of 45 mg daily of elemental iron. Higher doses frequently cause gastrointestinal side effects such as nausea and vomiting (7135) and might increase the risk of preterm labor (100969). High hemoglobin concentrations at the time of delivery are associated with adverse pregnancy outcomes (7135,20109).
Below is general information about the interactions of the known ingredients contained in the product Daily Psyllium Fiber. 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, black psyllium might reduce the effects of carbamazepine and increase the risk for convulsions.
 Details
Theoretically, black psyllium might reduce carbamazepine absorption. A preliminary study using blond psyllium reported decreased carbamazepine bioavailability due to binding of the drug to psyllium, as well as reduction of available fluid in the gut for dissolution of the drug (539). This interaction may also occur with black psyllium.
|
Theoretically, taking black psyllium at the same time as digoxin might reduce digoxin absorption and decrease digoxin levels.
Details
|
Theoretically, taking black 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. This is unlikely to be clinically significant (12421).
|
Theoretically, taking black psyllium at the same time as lithium might reduce lithium absorption.
Details
The fiber in black psyllium might reduce lithium absorption and plasma levels. Some case reports describe a reduction in plasma lithium levels with concomitant administration of blond psyllium. This was reversed when psyllium was stopped (540,92194). This interaction may also occur with black psyllium.
|
Theoretically, black psyllium might increase the therapeutic and adverse effects of metformin.
Details
Animal research shows that concurrent consumption of blond psyllium with metformin slows and increases the absorption of metformin (99433). This interaction may also occur with black psyllium. To avoid changes in absorption, take psyllium 30-60 minutes after metformin.
|
Theoretically, taking black psyllium at the same time as olanzapine might reduce olanzapine absorption.
Details
The fiber in black psyllium might decrease the absorption of olanzapine. A single case report describes a reduction in the effectiveness of olanzapine when it was concomitantly administered 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). 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). Although many of these studies evaluated blond psyllium, the fiber content in black psyllium may have similar effects.

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).
|
Iron reduces the absorption of bisphosphonates.
Details
Advise patients that doses of bisphosphonates should be separated by at least two hours from doses of all other medications, including supplements such as iron. Divalent cations, including iron, can decrease absorption of bisphosphonates by forming insoluble complexes in the gastrointestinal tract (15).
|
Theoretically, taking chloramphenicol with iron might reduce the response to iron therapy in iron deficiency anemia.
Details
|
Iron might decrease dolutegravir levels by reducing its absorption.
Details
Advise patients to take dolutegravir at least 2 hours before or 6 hours after taking iron. Pharmacokinetic research shows that iron can decrease the absorption of dolutegravir from the gastrointestinal tract through chelation (93578). When taken under fasting conditions, a single dose of ferrous fumarate 324 mg orally along with dolutegravir 50 mg reduces overall exposure to dolutegravir by 54% (94190).
|
Theoretically, taking iron along with integrase inhibitors might decrease the levels and clinical effects of these drugs.
Details
Iron is a divalent cation. There is concern that iron may decrease the absorption of integrase inhibitors from the gastrointestinal tract through chelation (93578). One pharmacokinetic study shows that iron can decrease blood levels of the specific integrase inhibitor dolutegravir through chelation (94190). Also, other pharmacokinetic research shows that other divalent cations such as calcium can decrease the absorption and levels of some integrase inhibitors through chelation (93578,93579).
|
Iron might decrease levodopa levels by reducing its absorption.
Details
Advise patients to separate doses of levodopa and iron as much as possible. There is some evidence in healthy people that iron forms chelates with levodopa, reducing the amount of levodopa absorbed by around 50% (9567). The clinical significance of this hasn't been determined.
|
Iron might decrease levothyroxine levels by reducing its absorption.
Details
Advise patients to separate levothyroxine and iron doses by at least 2 hours. Iron can decrease the absorption and efficacy of levothyroxine by forming insoluble complexes in the gastrointestinal tract (9568).
|
Iron might decrease methyldopa levels by reducing its absorption.
Details
|
Theoretically, iron might decrease mycophenolate mofetil levels by reducing its absorption.
Details
Advise patients to take iron 4-6 hours before, or 2 hours after, mycophenolate mofetil. It has been suggested that a decrease of absorption is possible, probably by forming nonabsorbable chelates. However, mycophenolate pharmacokinetics are not affected by iron supplementation in available clinical research (3046,20152,20153,20154,20155).
|
Iron might decrease penicillamine levels by reducing its absorption.
Details
Advise patients to separate penicillamine and iron doses by at least 2 hours. Oral iron supplements can reduce absorption of penicillamine by 30% to 70%, probably due to chelate formation. In people with Wilson's disease, this interaction has led to reduced efficacy of penicillamine (3046,3072,20156).
|
Iron might decrease levels of quinolone antibiotics by reducing their absorption.
Details
|
Iron might decrease levels of tetracycline antibiotics by reducing their absorption.
Details
Advise patients to take iron at least 2 hours before or 4 hours after tetracycline antibiotics. Concomitant use can decrease absorption of tetracycline antibiotics from the gastrointestinal tract by 50% to 90% (15).

Below is general information about the adverse effects of the known ingredients contained in the product Daily Psyllium Fiber. 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, black psyllium is generally well tolerated when taken with adequate fluids.
Most Common Adverse Effects:
Orally: Bloating, flatulence.
Serious Adverse Effects (Rare):
Orally: Bowel obstruction, esophageal obstruction.
Gastrointestinal ...Black psyllium can cause flatulence and bloating. These effects are generally transient and can be reduced by increasing the daily dose gradually (93214). Taking black psyllium with too little fluid can lead to esophageal or intestinal obstruction (18,93217,93218).
Immunologic ...Several psyllium species have been associated with sensitization and allergic reactions, especially in people exposed to airborne psyllium dust, such as nurses preparing doses of psyllium powder, and workers in psyllium processing plants (93214). Symptoms of occupational exposure include rhinitis, conjunctivitis, wheezing, asthma, and urticarial rashes (18,93214). Severe anaphylactic reactions have been reported in individuals with occupational exposure who then ingest psyllium products (2329,8079,9246).
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 or intravenously, iron is generally well tolerated when used appropriately.
Most Common Adverse Effects:
Orally: Abdominal pain, constipation, diarrhea, gastrointestinal irritation, nausea, and vomiting.
Serious Adverse Effects (Rare):
Orally: Case reports have raised concerns about oral or gastric ulcerations.
Intravenously: Case reports have raised concerns about hypophosphatemia and osteomalacia.
Cardiovascular
...There is debate regarding the association between coronary heart disease (CHD) or myocardial infarction (MI) and high iron intake or high body iron stores.
Some observational studies have reported that high body iron stores are associated with increased risk of MI and CHD (1492,9542,9544,9545,15175). Some observational studies reported that only high heme iron intake from dietary sources such as red meat are associated with increased risk of MI and CHD (1492,9546,15174,15205,15206,91180). However, the majority of research has found no association between serum iron levels and cardiovascular disease (1097,1099,9543,9547,9548,9549,9550,56469,56683).
There is one case of Kounis syndrome, also referred to as allergic angina or allergic myocardial infarction, in a 39-year-old female patient without previous coronary artery disease given intravenous ferric carboxymaltose. The patient experienced anaphylactic symptoms, including headache, abdominal pain, and breathing difficulties, 3 minutes after starting the infusion. She was further diagnosed with non-ST-elevation myocardial infarction (112607).
Dermatologic ...Cutaneous hemosiderosis, or skin staining, has been reported following intravenous iron infusion in various case reports. Most of these cases are due to extravasation following iron infusion (112605,112611). In one case, extravasation has occurred following iron derisomaltose infusion in a 41-year-old female with chronic kidney disease (112605). Rarely, diffuse cutaneous hermosiderosis has occurred. In one case, a 31-year-old female with excessive sweating developed cutaneous hemosiderosis in the armpits following an intravenous iron polymaltose infusion (112611).
Endocrine ...Population research in females shows that higher ferritin levels are associated with an approximately 1. 5-fold higher odds of developing gestational diabetes. Increased dietary intake of heme-iron, but not non-heme iron, is also associated with an increased risk for gestational diabetes. The effects of iron supplementation could not be determined from the evaluated research (96618). However, in a sub-analysis of a large clinical trial in pregnant adults, daily supplementation with iron 100 mg from 14 weeks gestation until delivery did not affect the frequency or severity of glucose intolerance or gestational weight gain (96619).
Gastrointestinal
...Orally, iron can cause dry mouth, gastrointestinal irritation, heartburn, abdominal pain, constipation, diarrhea, nausea, or vomiting (96621,102864,104680,104684,110179,110185,110188,110189,110192).
These adverse effects are uncommon at doses below the tolerable upper intake level (UL) of 45 mg per day of elemental iron in adults with normal iron stores (7135). Higher doses can be taken safely in adults with iron deficiency, but gastrointestinal side effects may occur (1095,20118,20119,56698,102864). Taking iron supplements with food seems to reduce gastrointestinal side effects (7135). However, food can also significantly reduce iron absorption. Iron should be taken on an empty stomach, unless it cannot be tolerated.
There are several formulations of iron products such as ferrous sulfate, ferrous gluconate, ferrous fumarate, and others. Manufacturers of some formulations, such as polysaccharide-iron complex products (Niferex-150, etc), claim to be better tolerated than other formulations; however, there is no reliable evidence to support this claim. Gastrointestinal tolerability relates mostly to the elemental iron dose rather than the formulation (17500).
Enteric-coated or controlled-release iron formulations might reduce nausea for some patients, however, these products also have lower absorption rates (17500).
Liquid oral preparations can blacken and stain teeth (20118).
Iron can also cause oral ulcerations and ulcerations of the gastric mucosa (56684,91182,96622,110179). In one case report, an 87-year-old female with Alzheimer disease experienced a mucosal ulceration, possibly due to holding a crushed ferrous sulfate 80 mg tablet in the mouth for too long prior to swallowing (91182). The ulceration was resolved after discontinuing iron supplementation. In another case report, a 76-year old male suffered gastric mucosal injury after taking a ferrous sulfate tablet daily for 4 years (56684). In a third case report, a 14-year-old female developed gastritis involving symptoms of upper digestive hemorrhage, nausea, melena, and stomach pain. The hemorrhage was attributed to supplementation with ferrous sulfate 2 hours after meals for the prior 2 weeks (96622). In one case report, a 43-year old female developed atrophic gastritis with non-bleeding ulcerations five days after starting oral ferrous sulfate 325 mg twice daily (110179).
Intravenously, iron can cause gastrointestinal symptoms sch as nausea (104684,110192).
Immunologic
...Although there is some clinical research associating iron supplementation with an increased rate of malaria infection (56796,95432), the strongest evidence to date does not support this association, at least for areas where antimalarial treatment is available (95433,96623).
In an analysis of 14 trials, iron supplementation was not associated with an increased risk of malaria (96623). In a sub-analysis of 7 preliminary clinical studies, the effect of iron supplementation was dependent upon the access to services for antimalarial treatment. In areas where anemia is common and services are available, iron supplementation is associated with a 9% reduced risk of clinical malaria. In an area where services are unavailable, iron supplementation was associated with a 16% increased risk in malaria incidence (96623). The difference in these findings is likely associated with the use of malaria prevention methods.
A meta-analysis of clinical studies of all patient populations shows that administering IV iron, usually iron sucrose and ferric carboxymaltose, increases the risk of infection by 16% when compared with oral iron or no iron. However, sub-analyses suggest this increased risk is limited to patients with inflammatory bowel disease (IBD) (110186).
Intravenously, iron has rarely resulted in allergic reactions, including anaphylactoid reactions (110185,110192,112606,112607). There is one case of Kounis syndrome, also referred to as allergic angina or allergic myocardial infarction, in a 39-year-old female patient without previous coronary artery disease given intravenous ferric carboxymaltose. The patient experienced anaphylactic symptoms, including headache, abdominal pain, and breathing difficulties, 3 minutes after starting the infusion. She was further diagnosed with non-ST-elevation myocardial infarction (112607).
Musculoskeletal ...Intravenously, iron rarely results in osteomalacia related to hypophosphatemia (112609). At least 2 cases exist of hypophosphatemic osteomalacia. In one case, a 70-year-old male with a genetic hemorrhagic disorder infused with ferric carboxymaltose developed lower limb pain with hypophosphatemia and diffuse bone demineralization in the feet (112609). In a second case, a 61-year-old male developed femoral neck insufficiency fractures following repeated ferric carboxymaltose transfusions for anemia related to vascular malformation in the bowel (112603). Severe hypophosphatemia requiring intravenous phosphate in the absence of osteomalacia has also occurred following intravenous ferric carboxymaltose (112608,112610).
Oncologic
...There is a debate regarding the association between high levels of iron stores and cancer.
Data are conflicting and inconclusive (1098,1099,1100,1102). Epidemiological studies suggest that increased body iron stores may increase the risk of cancer or general mortality (56703).
Occupational exposure to iron may be carcinogenic (56691). Oral exposure to iron may also be carcinogenic. Pooled analyses of population studies suggest that increasing the intake of heme iron increases the risk of colorectal cancer. For example, increasing heme iron intake by 1 mg/day is associated with an 11% increase in risk (56699,91185).
Other ...Intravenously, sodium ferric gluconate complex (SFGC) caused drug intolerance reactions in 0. 4% of hemodialysis patients including 2 patients with pruritus and one patient each with anaphylactoid reaction, hypotension, chills, back pain, dyspnea/chest pain, facial flushing, rash and cutaneous symptoms of porphyria (56527).
