Theoretically, the antioxidant effects of alpha-lipoic acid might alter the effectiveness of alkylating agents.
 Details
The use of antioxidants like alpha-lipoic acid during chemotherapy is controversial. There are concerns that antioxidants could reduce the activity of chemotherapy drugs that generate free radicals (391). However, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that might interfere with apoptosis (cell death) of cancer cells (14012,14013). More evidence is needed to determine what effect, if any, antioxidants such as alpha-lipoic acid have on chemotherapy. Advise patients to consult their oncologist before using alpha-lipoic acid.

Theoretically, alpha-lipoic acid may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
In vitro, alpha-lipoic acid inhibits platelet aggregation (98682).
|
Theoretically, taking alpha-lipoic acid with antidiabetes drugs might increase the risk of hypoglycemia.
Details
Although some small clinical studies have suggested that alpha-lipoic acid can lower blood glucose levels (3545,3874,3875,3876,20490,20493,104650), larger clinical studies in patients with diabetes have shown no clinically meaningful effect (20494,20495,20496,90443,90445,110118). Additionally, co-administration of single doses of alpha-lipoic acid and glyburide or acarbose did not cause detectable drug interactions in healthy volunteers (3870).

Theoretically, alpha-lipoic acid might decrease the effects of thyroid hormone drugs.
Details
Animal research suggests that co-administration of thyroxine with alpha-lipoic acid reduces conversion into the active T3 form (8946).
|
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 Super R Lipoic Acid. 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
...Alpha-lipoic acid appears to be generally well tolerated when used orally, intravenously, or topically.
Most Common Adverse Effects:
Orally: Headache, heartburn, nausea, and vomiting.
Topically: Irritation and rash.
Intravenously: Nausea and vomiting.
Serious Adverse Effects (Rare):
Orally: Case reports have raised concerns about insulin autoimmune syndrome (IAS).
Cardiovascular ...Orally, hypotension has been reported rarely in a clinical trial (104650).
Dermatologic ...Orally, skin rash and itching have been reported after use of alpha-lipoic acid (16391,20490,21674,96233,104650). Topically, alpha-lipoic acid can cause local irritation, including burning, stinging, mild rash, or contact dermatitis (12021,30836,111701). In one case, an 86-year-old female developed allergic contact dermatitis with severe itching and oozing after applying alpha-lipoic acid 5% cream to her lower extremities. The patient had a positive skin patch test for alpha-lipoic acid, confirming the causative agent (111701). In another case, a 47-year-old female developed contact dermatitis characterized by a pruritic rash and labial adhesions hours after applying a 5% vulvar serum containing lipoic acid 0.9 grams, vitamin E, vitamin C, hyaluronic acid, and retinol palmitate to the vulva to treat vulvar lichen sclerosis. Testing confirmed that the causative agent was alpha-lipoic acid (111704). Intravenously, local allergic reactions have occurred at the injection site (1547).
Endocrine ...Orally, at least 50 published cases of insulin autoimmune syndrome (IAS) thought to be associated with use of alpha-lipoic acid have been reported (16392,104656,104657,104658,104659,107893,112941). Most reported cases have been associated with alpha-lipoic acid supplements or enriched foods; IAS has not been reported with intake of alpha-lipoic acid in food. IAS has been linked to compounds, such as alpha-lipoic acid, that contain sulfhydryl groups, but it is unclear if taking alpha-lipoic acid with other drugs known to trigger IAS increases the risk (107893,112941). IAS is characterized by very high serum insulin levels and high titers of autoantibodies against endogenous insulin. Sulfhydryl groups interact with disulfide bonds of insulin, increasing its immunogenicity (112941). Symptoms include severe spontaneous hypoglycemic episodes, as well as hunger and neuroglycopenic symptoms such as blurred vision, weakness, confusion, dizziness, sweating, and palpitations (104656,104657,107893,112941). Time to onset of IAS ranges from 1 week to 4 months (107893). Most cases of IAS have been reported in Japan and have occurred in individuals with the human leucocyte antigen (HLA)-DRB1*04:06 allele (16392,104656,107893). For patients of European decent, cases of IAS have mainly occurred in individuals with the HLA-DRB1*04:03 allele (104656,104658,104659,107893). This suggests that either of these alleles might produce a genetic predisposition to alpha-lipoic acid-associated IAS. Reported doses of alpha-lipoic acid have ranged from 200-800 mg daily, most commonly 600 mg daily (104656,104658,104659,107893). IAS-related hypoglycemic episodes have been treated with oral or intravenous glucose or sucrose, as well as prednisone. Episodes decline following discontinuation of alpha-lipoic acid, and insulin values normalize within 3-9 months (104656,104658,104659,107893).
Gastrointestinal ...Orally, heartburn, nausea, and vomiting have been reported after use of alpha-lipoic acid (3557,12106,16391,20475,30844,96225,101868,103327,103328,103333)(103335,104650,104654,104655). Higher doses (1200-1800 mg daily) seem to cause more severe effects than lower doses (600 mg daily) (3557,20475,30844,96225). Alpha-lipoic acid may also cause a burning sensation from the throat to the stomach, abdominal discomfort, or bitter taste when used orally (20478,20490,21664,96225). Intravenously, alpha-lipoic acid can cause gastrointestinal upset, including nausea and vomiting. Adverse effects are more common in patients receiving higher intravenous doses (3557) and may be more common in the elderly (96225).
Genitourinary ...Orally, alpha-lipoic acid may cause urinary disorders (20479). Oral alpha-lipoic acid has also been associated with a change in urine odor (96225,103327).
Neurologic/CNS
...Orally, alpha-lipoic acid may cause headache (21664,103328,104655) or dizziness (104650).
Intravenously, paresthesias have been reported to worsen temporarily at the beginning of therapy. Also, intravenous alpha-lipoic acid can cause headache. Adverse effects are more common in patients receiving higher intravenous doses (3557).
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).
