Below is general information about the safety of the known ingredients contained in the product Buddy Bear Gentle Lax Natural Chocolate Cream Flavor. 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 the fresh or dried fruit is used orally in amounts commonly found in foods.
POSSIBLY SAFE ...when fig fruit paste is consumed orally in amounts of up to 300 grams daily for up to 8 weeks (99956).
POSSIBLY UNSAFE ...when fig leaf decoctions are used topically. Fig leaf contains psoralens (12579,12581). There have been reports of photodermatitis with burn-like lesions and rashes after fig decoctions were applied prior to sun exposure (49962,49968,49973,49975,49981). There is insufficient reliable information available about the safety of fig leaf when used orally.
PREGNANCY AND LACTATION: LIKELY SAFE
when the fresh or dried fruit is used orally in amounts commonly found in foods.
There is insufficient reliable information available about the safety of fig leaf or fruit used in medicinal amounts during pregnancy and lactation; avoid use.
LIKELY SAFE ...when used orally and appropriately. Oral magnesium is safe when used in doses below the tolerable upper intake level (UL) of 350 mg daily (7555). ...when used parenterally and appropriately. Parenteral magnesium sulfate is an FDA-approved prescription product (96484).
POSSIBLY UNSAFE ...when used orally in excessive doses. Doses greater than the tolerable upper intake level (UL) of 350 mg daily frequently cause loose stools and diarrhea (7555).
CHILDREN: LIKELY SAFE
when used orally and appropriately.
Magnesium is safe when used in doses below the tolerable upper intake level (UL) of 65 mg daily for children 1 to 3 years, 110 mg daily for children 4 to 8 years, and 350 mg daily for children older than 8 years (7555,89396). ...when used parenterally and appropriately (96483).
CHILDREN: LIKELY UNSAFE
when used orally in excessive doses.
Tell patients not to use doses above the tolerable upper intake level (UL). Higher doses can cause diarrhea and symptomatic hypermagnesemia including hypotension, nausea, vomiting, and bradycardia (7555,8095).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately.
Magnesium is safe for those pregnant and breast-feeding when used in doses below the tolerable upper intake level (UL) of 350 mg daily (7555).
PREGNANCY AND LACTATION: POSSIBLY SAFE
when prescription magnesium sulfate is given intramuscularly and intravenously prior to delivery for up to 5 days (12592,89397,99354,99355).
However, due to potential adverse effects associated with intravenous and intramuscular magnesium, use during pregnancy is limited to patients with specific conditions such as severe pre-eclampsia or eclampsia. There is some evidence that intravenous magnesium can increase fetal mortality and adversely affect neurological and skeletal development (12590,12593,60818,99354,99355). However, a more recent analysis of clinical research shows that increased risk of fetal mortality seems to occur only in the studies where antenatal magnesium is used for tocolysis and not for fetal neuroprotection or pre-eclampsia/eclampsia (102457). Furthermore, antenatal magnesium does not seem to be associated with increased risk of necrotizing enterocolitis in preterm infants (104396). There is also concern that magnesium increases the risk of maternal adverse events. A meta-analysis of clinical research shows that magnesium sulfate might increase the risk of maternal adverse events, especially in Hispanic mothers compared to other racial and ethnic groups (60971,99319).
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used orally in excessive doses.
Tell patients to avoid exceeding the tolerable upper intake level (UL) of 350 mg daily. Taking magnesium orally in higher doses can cause diarrhea (7555). ...when prescription magnesium sulfate is given intramuscularly and intravenously prior to delivery for longer than 5 days (12592,89397,99354,99355). Maternal exposure to magnesium for longer than 5-7 days is associated with an increase in neonatal bone abnormalities such as osteopenia and fractures. The U.S. Food and Drug Administration (FDA) recommends that magnesium injection not be given for longer than 5-7 days (12590,12593,60818,99354,99355).
LIKELY SAFE ...when used orally in the amounts typically found in food.
POSSIBLY SAFE ...when dried plums are used orally as a medicine. Dried plums have been used with apparent safety at doses of up to 100 grams daily for up to 12 months (95271,95272,95280,95281,95295). ...when plum juice or dried plum essence is used orally as a medicine. Plum juice has been consumed with apparent safety at a dose of up to 250 mL daily for up to 2 weeks (95293,95294). Dried plum essence has been consumed with apparent safety at a dose of up to 100 mL daily for up to 4 weeks (95274).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using amounts greater than those found in food.
LIKELY SAFE ...when the stalk is used in amounts commonly found in foods and when the root is used as a food flavoring. Rhubarb has Generally Recognized as Safe (GRAS) status in the US (4912).
POSSIBLY SAFE ...when the root or rhizome is used orally and appropriately in medicinal amounts for up to 2 years (92294,92295,92297). ...when the stalk is used orally and appropriately in medicinal amounts for up to 4 weeks (71351,71363,97920). ...when used topically and appropriately (10437,97919).
POSSIBLY UNSAFE ...when the leaf is used orally. Rhubarb leaf contains oxalic acid and soluble oxalate, which can cause abdominal pain, burning of the mouth and throat, diarrhea, nausea, vomiting, seizures, and death (17).
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used in medicinal amounts, rhubarb root is a stimulant laxative; avoid using (12).
Below is general information about the interactions of the known ingredients contained in the product Buddy Bear Gentle Lax Natural Chocolate Cream Flavor. 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, fig leaf might enhance the blood glucose lowering effects of hypoglycemic drugs.
 Details
A small clinical study in patients with type 1 diabetes shows that consuming a tea made from fig leaves modestly reduces postprandial glucose levels and insulin requirements (12578).

A small clinical study in patients with type 1 diabetes shows that consuming a tea made from fig leaves modestly reduces postprandial glucose levels and insulin requirements (12578).
|
Concomitant use of aminoglycoside antibiotics and magnesium can increase the risk for neuromuscular weakness.
Details
Both aminoglycosides and magnesium reduce presynaptic acetylcholine release, which can lead to neuromuscular blockade and possible paralysis. This is most likely to occur with high doses of magnesium given intravenously (13362).
|
Use of acid reducers may reduce the laxative effect of magnesium oxide.
Details
A retrospective analysis shows that, in the presence of H2 receptor antagonists (H2RAs) or proton pump inhibitors (PPIs), a higher dose of magnesium oxide is needed for a laxative effect (90033). This may also occur with antacids. Under acidic conditions, magnesium oxide is converted to magnesium chloride and then to magnesium bicarbonate, which has an osmotic laxative effect. By reducing acidity, antacids may reduce the conversion of magnesium oxide to the active bicarbonate salt.
|
Theoretically, magnesium may have antiplatelet effects, but the evidence is conflicting.
Details
In vitro evidence shows that magnesium sulfate inhibits platelet aggregation, even at low concentrations (20304,20305). Some preliminary clinical evidence shows that infusion of magnesium sulfate increases bleeding time by 48% and reduces platelet activity (20306). However, other clinical research shows that magnesium does not affect platelet aggregation, although inhibition of platelet-dependent thrombosis can occur (60759).
|
Magnesium can decrease absorption of bisphosphonates.
Details
Cations, including magnesium, can decrease bisphosphonate absorption. Advise patients to separate doses of magnesium and these drugs by at least 2 hours (13363).
|
Magnesium can have additive effects with calcium channel blockers, although evidence is conflicting.
Details
Magnesium inhibits calcium entry into smooth muscle cells and may therefore have additive effects with calcium channel blockers. Severe hypotension and neuromuscular blockades may occur when nifedipine is used with intravenous magnesium (3046,20264,20265,20266), although some contradictory evidence suggests that concurrent use of magnesium with nifedipine does not increase the risk of neuromuscular weakness (60831). High doses of magnesium could theoretically have additive effects with other calcium channel blockers.
|
Magnesium salts may reduce absorption of digoxin.
Details
|
Gabapentin absorption can be decreased by magnesium.
Details
Clinical research shows that giving magnesium oxide orally along with gabapentin decreases the maximum plasma concentration of gabapentin by 33%, time to maximum concentration by 36%, and area under the curve by 43% (90032). Advise patients to take gabapentin at least 2 hours before, or 4 to 6 hours after, magnesium supplements.
|
Magnesium might precipitate ketamine toxicity.
Details
In one case report, a 62-year-old hospice patient with terminal cancer who had been stabilized on sublingual ketamine 150 mg four times daily experienced severe ketamine toxicity lasting for 2 hours after taking a maintenance dose of ketamine following an infusion of magnesium sulfate 2 grams (105078). Since both magnesium and ketamine block the NMDA receptor, magnesium is thought to have potentiated the effects of ketamine.
|
Magnesium can reduce the bioavailability of levodopa/carbidopa.
Details
Clinical research in healthy volunteers shows that taking magnesium oxide 1000 mg with levodopa 100 mg/carbidopa 10 mg reduces the area under the curve (AUC) of levodopa by 35% and of carbidopa by 81%. In vitro and animal research shows that magnesium produces an alkaline environment in the digestive tract, which might lead to degradation and reduced bioavailability of levodopa/carbidopa (100265).
|
Potassium-sparing diuretics decrease excretion of magnesium, possibly increasing magnesium levels.
Details
Potassium-sparing diuretics also have magnesium-sparing properties, which can counteract the magnesium losses associated with loop and thiazide diuretics (9613,9614,9622). Theoretically, increased magnesium levels could result from concomitant use of potassium-sparing diuretics and magnesium supplements.
|
Magnesium decreases absorption of quinolones.
Details
Magnesium can form insoluble complexes with quinolones and decrease their absorption (3046). Advise patients to take these drugs at least 2 hours before, or 4 to 6 hours after, magnesium supplements.
|
Sevelamer may increase serum magnesium levels.
Details
In patients on hemodialysis, sevelamer use was associated with a 0.28 mg/dL increase in serum magnesium. The mechanism of this interaction remains unclear (96486).
|
Parenteral magnesium alters the pharmacokinetics of skeletal muscle relaxants, increasing their effects and accelerating the onset of effect.
Details
Parenteral magnesium shortens the time to onset of skeletal muscle relaxants by about 1 minute and prolongs the duration of action by about 2 minutes. Magnesium potentiates the effects of skeletal muscle relaxants by decreasing calcium-mediated release of acetylcholine from presynaptic nerve terminals, reducing postsynaptic sensitivity to acetylcholine, and having a direct effect on the membrane potential of myocytes (3046,97492,107364). Magnesium also has vasodilatory actions and increases cardiac output, allowing a greater amount of muscle relaxant to reach the motor end plate (107364). A clinical study found that low-dose rocuronium (0.45 mg/kg), when given after administration of magnesium 30 mg/kg over 10 minutes, has an accelerated onset of effect, which matches the onset of effect seen with a full-dose rocuronium regimen (0.6 mg/kg) (96485). In another clinical study, onset times for rocuronium doses of 0.3, 0.6, and 1.2 mg/kg were 86, 76, and 50 seconds, respectively, when given alone, but were reduced to 66, 44, and 38 seconds, respectively, when the doses were given after a 15-minute infusion of magnesium sulfate 60 mg/kg (107364).
|
Magnesium increases the systemic absorption of sulfonylureas, increasing their effects and side effects.
Details
Clinical research shows that administration of magnesium hydroxide with glyburide increases glyburide absorption, increases maximal insulin response by 35-fold, and increases the risk of hypoglycemia, when compared with glyburide alone (20307). A similar interaction occurs between magnesium hydroxide and glipizide (20308). The mechanism of this effect appears to be related to the elevation of gastrointestinal pH by magnesium-based antacids, increasing solubility and enhancing absorption of sulfonylureas (22364).
|
Magnesium decreases absorption of tetracyclines.
Details
Magnesium can form insoluble complexes with tetracyclines in the gut and decrease their absorption and antibacterial activity (12586). Advise patients to take these drugs 1 hour before or 2 hours after magnesium supplements.
|
Theoretically, plum juice might have antiplatelet effects.
Details
|
Theoretically, frequent and high doses of rhubarb might increase the risk of hypokalemia when taken with corticosteroids.
Details
|
Theoretically, taking rhubarb with cyclosporine might reduce cyclosporine levels.
Details
Animal research shows that co-administration of rhubarb decoction 0.25 or 1 gram/kg with cyclosporine 2.5 mg/kg, decreases cyclosporine maximum plasma concentration and overall exposure levels when compared with taking cyclosporine alone. The authors theorize that rhubarb might reduce cyclosporine bioavailability by inducing of P-glycoprotein and/or cytochrome P450 3A4 (92304). However, since rhubarb was administered as a single oral dose and enzyme induction usually occurs after multiple doses, it is possible that cyclosporine absorption was actually reduced via rhubarb's stimulant laxative effects (12). Also, the composition of the rhubarb decoction was not described.
|
Theoretically, overuse of rhubarb might increase the risk of adverse effects when taken with digoxin.
Details
|
Theoretically, frequent and high doses of rhubarb might increase the risk of hypokalemia.
Details
|
Theoretically, concomitant use of rhubarb with potentially hepatotoxic drugs might increase the risk of developing liver damage.
Details
|
Theoretically, long-term use of anthraquinones from rhubarb might increase the risk of nephrotoxicity when used with nephrotoxic drugs.
Details
The anthraquinone constituents of rhubarb have been shown to induce nephrotoxicity in animal research (71322). Additionally, in a case report, a 23-year old female presented with kidney failure after taking 6 tablets of a proprietary slimming agent (found to contain the anthraquinones emodin and aloe-emodin from rhubarb) daily for 6 weeks and then adding diclofenac 25 mg 4 times daily for 2 days. The authors postulate that the anthraquinone constituents of rhubarb contributed to the renal dysfunction, and the addition of diclofenac, a nephrotoxic drug, led to renal failure (15257). Until more is known, advise patients to avoid taking rhubarb if they are taking other potentially nephrotoxic drugs.
|
Theoretically, rhubarb might increase the risk for fluid and electrolyte loss when taken with other stimulant laxatives.
Details
|
Theoretically, excessive use of rhubarb might increase the risk of bleeding when taken with warfarin.

Below is general information about the adverse effects of the known ingredients contained in the product Buddy Bear Gentle Lax Natural Chocolate Cream Flavor. 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, the fresh or dried fig fruit is well tolerated in amounts commonly found in foods.
A thorough evaluation of safety outcomes has not been conducted when fig fruit is used orally as medicine.
Topically, fig leaf may cause photodermatitis. There is limited reliable information available about the safety of fig fruit or latex when applied topically.
Serious Adverse Effects (Rare):
Orally: Allergy and, in rare cases, anaphylaxis.
Topically: The fig leaf may cause photodermatitis.
Dermatologic
...Topically, fig leaf might cause photodermatitis.
The leaf contains psoralens (12579,12581). Many cases of photodermatitis from fig leaf have been reported (49962,49968,49973,49975,49981). In at least two cases, the burns were serious enough to require hospitalization. Severe anemia and sepsis developed in one patient (49962). Avoid excessive sunlight or ultraviolet light exposure while using products containing fig leaf.
Orally, fig fruit is unlikely to cause photodermatitis (12581).
Immunologic ...Orally, fig fruit can cause allergy and, in rare cases, anaphylaxis (8815,12580). Topically, exposure to fig fruit and leaves can cause contact dermatitis. In some cases, sun exposure can make contact dermatitis worse (12689,99961).
General
...Magnesium is generally well tolerated.
Some clinical research shows no differences in adverse effects between placebo and magnesium groups.
Most Common Adverse Effects:
Orally: Diarrhea, gastrointestinal irritation, nausea, and vomiting.
Intravenously: Bradycardia, dizziness, flushing sensation, hypotension, and localized pain and irritation. In pregnancy, may cause blurry vision, dizziness, lethargy, nausea, nystagmus, and perception of warmth.
Serious Adverse Effects (Rare):
All ROAs: With toxic doses, loss of reflexes and respiratory depression can occur. High doses in pregnancy can increase risk of neonatal mortality and neurological defects.
Cardiovascular
...Intravenously, magnesium can cause bradycardia, tachycardia, and hypotension (13356,60795,60838,60872,60960,60973,60982,61001,61031).
Magnesium sulfate may cause rapid heartbeat when administered antenatally (60915).
In one case report, a 99-year-old male who took oral magnesium oxide 3000 mg daily for chronic constipation was hospitalized with hypermagnesemia, hypotension, bradycardia, heart failure, cardiomegaly, second-degree sinoatrial block, and complete bundle branch block. The patient recovered after discontinuing the magnesium oxide (108966).
Dermatologic ...Intravenously, magnesium may cause flushing, sweating, and problems at the injection site (including burning pain) (60960,60982). In a case study, two patients who received intravenous magnesium sulfate for suppression of preterm labor developed a rapid and sudden onset of an urticarial eruption (a skin eruption of itching welts). The eruption cleared when magnesium sulfate was discontinued (61045). Orally, magnesium oxide may cause allergic skin rash, but this is rare. In one case report, a patient developed a rash after taking 600 mg magnesium oxide (Maglax) (98291).
Gastrointestinal
...Orally, magnesium can cause gastrointestinal irritation, nausea, vomiting, and diarrhea (1194,4891,10661,10663,18111,60951,61016,98290).
In rare cases, taking magnesium orally might cause a bezoar, an indigestible mass of material which gets lodged in the gastrointestinal tract. In a case report, a 75-year-old female with advanced rectal cancer taking magnesium 1500 mg daily presented with nausea and anorexia from magnesium oxide bezoars in her stomach (99314). Magnesium can cause nausea, vomiting, or dry mouth when administered intravenously or by nebulization (60818,60960,60982,104400). Antenatal magnesium sulfate may also cause nausea and vomiting (60915). Two case reports suggest that giving magnesium 50 grams orally for bowel preparation for colonoscopy in patients with colorectal cancer may lead to intestinal perforation and possibly death (90006).
Delayed meconium passage and obstruction have been reported rarely in neonates after intravenous magnesium sulfate was given to the mother during pregnancy (60818). In a retrospective study of 200 neonates born prematurely before 32 weeks of gestation, administration of prenatal IV magnesium sulfate, as a 4-gram loading dose and then 1-2 grams hourly, was not associated with the rate of meconium bowel obstruction when compared with neonates whose mothers had not received magnesium sulfate (108728).
Genitourinary ...Intravenously, magnesium sulfate may cause renal toxicity or acute urinary retention, although these events are rare (60818,61012). A case of slowed cervical dilation at delivery has been reported for a patient administered intravenous magnesium sulfate for eclampsia (12592). Intravenous magnesium might also cause solute diuresis. In a case report, a pregnant patient experienced polyuria and diuresis after having received intravenous magnesium sulfate in Ringer's lactate solution for preterm uterine contractions (98284).
Hematologic ...Intravenously, magnesium may cause increased blood loss at delivery when administered for eclampsia or pre-eclampsia (12592). However, research on the effect of intravenous magnesium on postpartum hemorrhage is mixed. Some research shows that it does not affect risk of postpartum hemorrhage (60982), while other research shows that intrapartum magnesium administration is associated with increased odds of postpartum hemorrhage, increased odds of uterine atony (a condition that increases the risk for postpartum hemorrhage) and increased need for red blood cell transfusions (97489).
Musculoskeletal
...Intravenously, magnesium may cause decreased skeletal muscle tone, muscle weakness, or hypocalcemic tetany (60818,60960,60973).
Although magnesium is important for normal bone structure and maintenance (272), there is concern that very high doses of magnesium may be detrimental. In a case series of 9 patients receiving long-term tocolysis for 11-97 days, resulting in cumulative magnesium sulfate doses of 168-3756 grams, a lower bone mass was noted in 4 cases receiving doses above 1000 grams. There was one case of pregnancy- and lactation-associated osteoporosis and one fracture (108731). The validity and clinical significance of this data is unclear.
Neurologic/CNS ...Intravenously, magnesium may cause slurred speech, dizziness, drowsiness, confusion, or headaches (60818,60960). With toxic doses, loss of reflexes, neurological defects, drowsiness, confusion, and coma can occur (8095,12589,12590).
Ocular/Otic ...Cases of visual impairment or nystagmus have been reported following magnesium supplementation, but these events are rare (18111,60818).
Psychiatric ...A case of delirium due to hypermagnesemia has been reported for a patient receiving intravenous magnesium sulfate for pre-eclampsia (60780).
Pulmonary/Respiratory ...Intravenously, magnesium may cause respiratory depression and tachypnea when used in toxic doses (12589,61028,61180).
Other ...Hypothermia from magnesium used as a tocolytic has been reported (60818).
General
...Orally, plum seems to be well tolerated.
Most Common Adverse Effects:
Orally: Gastrointestinal effects, including flatulence and diarrhea.
Serious Adverse Effects (Rare):
Orally: Allergic reactions. Consumption of dried plums or plum pits has been reported to cause bowel obstruction and esophageal perforation.
Gastrointestinal
...Orally, plum has been reported to cause gastrointestinal issues (95272,95276,95285), including flatulence (95293) and diarrhea (95300).
In one case report, small bowel obstruction with impaction in the terminal ileum occurred in a 10-month old infant who consumed a dried plum. This was likely due to the infant being unable to properly chew the plum (95296).
Consumption of plum pits has also caused serious gastrointestinal adverse effects. Ileal obstruction occurred in a 71-year-old female who swallowed a plum pit (101250). In a young male, ileostomy obstruction due to plum pits has occurred (95298). Swallowing a plum pit has also caused an esophageal perforation in a 75-year-old male (95285).
Immunologic ...Orally, plum has been reported to cause allergic reaction in sensitive individuals (95286,95297).
General
...Orally, rhubarb root and stalk are well tolerated when used in food amounts and seem to be well tolerated when used in medicinal amounts.
Rhubarb leaf contains oxalic acid and can be toxic. Topically, rhubarb seems to be well tolerated.
Most Common Adverse Effects:
Orally: Cramps, diarrhea, gastrointestinal discomfort, nausea, vomiting.
Topically: Rash.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis.
Cardiovascular ...Orally, chronic use or abuse of rhubarb can cause arrhythmias (12).
Dermatologic ...Orally, rhubarb taken alone or in combination with other ingredients has been reported to cause rash (71315,71342). Topically, short term application of a specific product (Pyralvex) containing rhubarb, salicylic acid, and ethanol to the gums has been reported to cause slight burning and dark discoloration of the gums in approximately 1% of patients (71369). It is unclear if this effect is due to rhubarb, other ingredients, or the combination.
Endocrine ...Orally, chronic use or abuse of rhubarb can cause electrolyte loss (especially potassium), hyperaldosteronism, albuminuria, and edema (12).
Gastrointestinal
...Orally, rhubarb can cause cramp-like or spasmodic gastrointestinal discomfort, watery diarrhea, and uterine contractions (18).
Rhubarb, alone or in combination with other ingredients, has also been reported to cause bloating, nausea, diarrhea, vomiting, and stomach upset or pain in clinical studies. Diarrhea is more common with a starting dose of at least 3 grams of extract (71315,71329,71339,71340,71341,71342,71373,92300). Chronic use or abuse of rhubarb can cause inhibition of gastric motility and pseudomelanosis coli (pigment spots in the intestinal mucosa) (12,6138).
Although some research suggests that rhubarb and other anthranoid laxatives might increase the risk of colorectal cancer due to pseudomelanosis coli (30743), more recent research suggests that this condition is harmless, typically reversed with rhubarb discontinuation, and not associated with an increased risk for colorectal adenoma or carcinoma (6138).
Hematologic ...Orally, chronic use or abuse of rhubarb can cause hematuria (12).
Hepatic ...Orally, chronic use of anthraquinone-containing products, such as rhubarb, has been associated with hepatotoxicity (15257). Use of rhubarb specifically has been linked to at least 24 reports of liver injury, although details on the dose of rhubarb and duration of use in these cases are not clear (100963). In one clinical study, rhubarb, taken in combination with other ingredients, has been reported to cause mild to moderate elevations of serum alanine aminotransferase (71315).
Immunologic ...Orally, rhubarb has rarely been reported to cause anaphylaxis (18).
Musculoskeletal ...Orally, chronic use or abuse of rhubarb can cause accelerated bone deterioration and muscular weakness (12).
Renal ...Orally, chronic use or abuse of rhubarb can cause electrolyte loss (especially potassium), albuminuria, hematuria, dehydration, and nephropathies (12). There is one case report of renal failure in a patient who took a product containing rhubarb for six weeks. The patient presented with renal failure two days after starting diclofenac, which is known to have nephrotoxic effects. It is hypothesized that the combination of diclofenac with the anthraquinone constituents of rhubarb precipitated renal dysfunction (15257).
