Below is general information about the safety of the known ingredients contained in the product Bronchial Clear. 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 or intravenously and appropriately. Calcium is safe when used in appropriate doses (7555,12928,12946,95817). However, excessive doses should be avoided. The Institute of Medicine sets the daily tolerable upper intake level (UL) for calcium according to age as follows: Age 0-6 months, 1000 mg; 6-12 months, 1500 mg; 1-8 years, 2500 mg; 9-18 years, 3000 mg; 19-50 years, 2500 mg; 51+ years, 2000 mg (17506). Doses over these levels can increase the risk of side effects such as kidney stone, hypercalciuria, hypercalcemia, and milk-alkali syndrome. There has also been concern that calcium intake may be associated with an increased risk of cardiovascular disease (CVD) and coronary heart disease (CHD), including myocardial infarction (MI). Some clinical research suggests that calcium intake, often in amounts over the recommended daily intake level of 1000-1300 mg daily for adults, is associated with an increased risk of CVD, CHD, and MI (16118,17482,91350,107233). However, these studies, particularly meta-analyses, have been criticized for excluding trials in which calcium was administered with vitamin D (94137). Many of these trials also only included postmenopausal females. Other analyses report conflicting results, and have not shown that calcium intake affects the risk of CVD, CHD, or MI (92994,93533,97308,107231). Advise patients not to consume more than the recommended daily intake of 1000-1200 mg per day and to consider total calcium intake from both dietary and supplemental sources (17484). Also, advise patients taking calcium supplements to take calcium along with vitamin D (93533).
POSSIBLY UNSAFE ...when used orally in excessive doses. The National Academy of Medicine sets the daily tolerable upper intake level (UL) for calcium according to age as follows: 19-50 years, 2500 mg; 51 years and older, 2000 mg (17506). Doses over these levels can increase the risk of side effects such as kidney stones, hypercalciuria, hypercalcemia, and milk-alkali syndrome. There has also been concern that calcium intake may be associated with an increased risk of cardiovascular disease (CVD) and coronary heart disease (CHD), including myocardial infarction (MI). Some clinical research suggests that calcium intake, often in amounts over the recommended daily intake level of 1000-1300 mg daily for adults, is associated with an increased risk of CVD, CHD, and MI (16118,17482,91350,107233).

Also, advise patients taking calcium supplements to take calcium along with vitamin D (93533).
CHILDREN: LIKELY SAFE
when used orally and appropriately.
Calcium is safe when used in appropriate doses (17506).
CHILDREN: POSSIBLY UNSAFE
when used orally in excessive doses.
The Institute of Medicine sets the daily tolerable upper intake level (UL) for calcium according to age as follows: 0-6 months, 1000 mg; 6-12 months, 1500 mg; 1-8 years, 2500 mg; 9-18 years, 3000 mg (17506). Doses over these levels can increase the risk of side effects such as kidney stones, hypercalciuria, hypercalcemia, and milk-alkali syndrome.
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately (945,1586,3263,3264,17506).
The World Health Organization (WHO) recommends prescribing oral calcium supplementation 1.5-2 grams daily during pregnancy to those with low dietary calcium intake to prevent pre-eclampsia (97347).
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used orally in excessive doses.
The Institute of Medicine sets the same daily tolerable upper intake level (UL) for calcium according to age independent of pregnancy status: 9-18 years, 3000 mg; 19-50 years, 2500 mg (17506). Doses over these amounts might increase the risk of neonatal hypocalcemia-induced seizures possibly caused by transient neonatal hypoparathyroidism in the setting of excessive calcium supplementation during pregnancy, especially during the third trimester. Neonatal hypocalcemia is a risk factor for neonatal seizures (97345).
POSSIBLY SAFE ...when the leaf extract is used orally and appropriately, short-term. Two specific products containing dried English ivy leaf extract 7 mg/mL (Prospan, PendoPharm; Prospanex, Engelhard Arzneimittel GmbH and Co. KG), taken in doses of 7.5 mL three times daily, have been used with apparent safety for up to 7 days (29903,106055). There is insufficient reliable information available about the safety of topical English ivy.
CHILDREN: POSSIBLY SAFE
when the leaf extract is used orally and appropriately, short-term.
Two specific products containing dried English ivy leaf extract 7 mg/mL (Prospan, PendoPharm; Prospanex, Engelhard Arzneimittel GmbH and Co. KG), taken in doses of 2.5-7.5 mL three times daily, has been used with apparent safety for up to 7 days in infants and children up to 18 years of age (29903,106055).
PREGNANCY:
Insufficient reliable information available; avoid using.
A small retrospective study suggests that taking English ivy leaf extract at an unknown dose or duration during pregnancy is not associated with changes in pregnancy duration, the rate of preterm birth, infant health complications, or infant deaths (110402). However, due to its small size, retrospective design, and insufficient information regarding dose and duration, further research is needed to determine the safety of English ivy during pregnancy.
LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used in amounts commonly found in foods. Thyme has Generally Recognized as Safe (GRAS) status in the US (4912).
POSSIBLY SAFE ...when thyme is used orally and appropriately in supplemental amounts. Orally, thyme, in combination with other herbs, has been used safely for up to 23 days (13557,49219,49223,78133). ...when diluted thyme oil is used topically, short-term. Diluted thyme oil has been used with apparent safety for up to 7 months (5177). There is insufficient reliable information available about the safety of thyme oil when used orally or when inhaled.
CHILDREN: LIKELY SAFE

Thyme has Generally Recognized as Safe (GRAS) status in the US (4912).
CHILDREN: POSSIBLY SAFE
when thyme is used orally in medicinal amounts in combination with English ivy.
Thyme has been used with apparent safety in combination with English ivy for up to 10 days (78181).
There is insufficient reliable information available about the safety of thyme oil when used orally or topically in children.
PREGNANCY AND LACTATION: LIKELY SAFE
when used in amounts commonly found in foods.
Thyme has Generally Recognized as Safe (GRAS) status in the US (4912). There is insufficient reliable information available about the safety of thyme when used in medicinal amounts during pregnancy and breast-feeding; avoid using.
Below is general information about the interactions of the known ingredients contained in the product Bronchial Clear. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Calcium citrate might increase aluminum absorption and toxicity. Other types of calcium do not increase aluminum absorption.
Details
Calcium citrate can increase the absorption of aluminum when taken with aluminum hydroxide. The increase in aluminum levels may become toxic, particularly in individuals with kidney disease (21631). However, the effect of calcium citrate on aluminum absorption is due to the citrate anion rather than calcium cation. Calcium acetate does not appear to increase aluminum absorption (93006).
|
Calcium reduces the absorption of bisphosphonates.
Details
Advise patients to take bisphosphonates at least 30 minutes before calcium, but preferably at a different time of day. Calcium supplements decrease absorption of bisphosphonates (12937).
|
Taking calcipotriene with calcium might increase the risk for hypercalcemia.
Details
Calcipotriene is a vitamin D analog used topically for psoriasis. It can be absorbed in sufficient amounts to cause systemic effects, including hypercalcemia (12938). Theoretically, combining calcipotriene with calcium supplements might increase the risk of hypercalcemia.
|
Intravenous calcium may decrease the effects of calcium channel blockers; oral calcium is unlikely to have this effect.
Details
Intravenous calcium is used to decrease the effects of calcium channel blockers in the management of overdose. Intravenous calcium gluconate has been used before intravenous verapamil (Isoptin) to prevent or reduce the hypotensive effects without affecting the antiarrhythmic effects (6124). But there is no evidence that dietary or supplemental calcium when taken orally interacts with calcium channel blockers (12939,12947).
|
Co-administration of intravenous calcium and ceftriaxone can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys.
Details
Avoid administering intravenous calcium in any form, such as parenteral nutrition or Lactated Ringers, within 48 hours of intravenous ceftriaxone. Case reports in neonates show that administering intravenous ceftriaxone and calcium can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys. In several cases, neonates have died as a result of this interaction (15794,21632). So far there are no reports in adults; however, there is still concern that this interaction might occur in adults.
|
Using intravenous calcium with digoxin might increase the risk of fatal cardiac arrhythmias.
Details
|
Theoretically, calcium may reduce the therapeutic effects of diltiazem.
Details
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation (10574). Theoretically, calcium might increase this risk of hypercalcemia and reduce the effectiveness of diltiazem.
|
Calcium seems to reduce levels of dolutegravir.
Details
Advise patients to take dolutegravir either 2 hours before or 6 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium carbonate 1200 mg concomitantly with dolutegravir 50 mg reduces plasma levels of dolutegravir by almost 40%. Calcium appears to decrease levels of dolutegravir through chelation (93578).
|
Calcium seems to reduce levels of elvitegravir.
Details
Advise patients to take elvitegravir either 2 hours before or 2 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium along with elvitegravir can reduce blood levels of elvitegravir through chelation (94166).
|
Calcium seems to reduce the absorption and effectiveness of levothyroxine.
Details
|
Theoretically, concomitant use of calcium and lithium may increase this risk of hypercalcemia.
Details
Clinical research suggests that long-term use of lithium may cause hypercalcemia in 10% to 60% of patients (38953). Theoretically, concomitant use of lithium and calcium supplements may further increase this risk.
|
Calcium seems to reduce the absorption of quinolone antibiotics.
Details
|
Calcium may reduce levels of raltegravir.
Details
Pharmacokinetic research shows that taking a single dose of calcium carbonate 3000 mg along with raltegravir 400 mg twice daily modestly decreases the mean area under the curve of raltegravir, but the decrease does not necessitate a dose adjustment of raltegravir (94164). However, a case of elevated HIV-1 RNA levels and documented resistance to raltegravir has been reported for a patient taking calcium carbonate 1 gram three times daily plus vitamin D3 (cholecalciferol) 400 IU three times daily in combination with raltegravir 400 mg twice daily for 11 months. It is thought that calcium reduced raltegravir levels by chelation, leading to treatment failure (94165).
|
Calcium seems to reduce the absorption of sotalol.
Details
Advise patients to separate doses by at least 2 hours before or 4-6 hours after calcium. Calcium appears to reduce the absorption of sotalol, probably by forming insoluble complexes (10018).
|
Calcium seems to reduce the absorption of tetracycline antibiotics.
Details
Advise patients to take oral tetracyclines at least 2 hours before, or 4-6 hours after calcium supplements. Taking calcium at the same time as oral tetracyclines can reduce tetracycline absorption. Calcium binds to tetracyclines in the gut (1843).
|
Taking calcium along with thiazides might increase the risk of hypercalcemia and renal failure.
Details
Thiazides reduce calcium excretion by the kidneys (1902). Using thiazides along with moderately large amounts of calcium carbonate increases the risk of milk-alkali syndrome (hypercalcemia, metabolic alkalosis, renal failure). Patients may need to have their serum calcium levels and/or parathyroid function monitored regularly.
|
Theoretically, calcium may reduce the therapeutic effects of verapamil.
Details
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation (10574). Theoretically, use of calcium supplements may increase this risk of hypercalcemia and reduce the effectiveness of verapamil.
|
Theoretically, English ivy might increase the levels of drugs metabolized by CYP2C19.
Details
In vitro research shows that English ivy inhibits CYP2C19 enzymes (96682). So far, this interaction has not been reported in humans.
|
Theoretically, English ivy might increase the levels of drugs metabolized by CYP2C8.
Details
In vitro research shows that English ivy inhibits CYP2C8 enzymes (96682). So far, this interaction has not been reported in humans.
|
Theoretically, English ivy might increase the levels of drugs metabolized by CYP2D6.
Details
In vitro research shows that English ivy inhibits CYP2D6 enzymes (96682). So far, this interaction has not been reported in humans.
|
Theoretically, concurrent use of anticholinergic drugs and thyme essential oil might reduce the effects of anticholinergic drugs.
Details
In vitro evidence suggests that thyme essential oil and specific essential oil constituents like thymohydroquinone and carvacrol can inhibit acetylcholinesterase (AChE) (78155). However, this effect has not been observed in humans.
|
Theoretically, thyme leaf extract might have additive effects with anticoagulant or antiplatelet drugs.
Details
|
Theoretically, concurrent use of cholinergic drugs and thyme essential oil might cause additive cholinergic effects.
Details
In vitro evidence suggests that thyme essential oil and specific essential oil constituents like thymohydroquinone and carvacrol can inhibit acetylcholinesterase (AChE) (78155). However, this effect has not been observed in humans.
|
Theoretically, thyme might competitively inhibit the effects of estrogen replacement therapy.
Details
In vitro research shows that thyme has estrogen receptor-binding activity and phytoestrogen content (3701). However, this effect has not been observed in humans.

Below is general information about the adverse effects of the known ingredients contained in the product Bronchial Clear. 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 and intravenously, calcium is well-tolerated when used appropriately.
Most Common Adverse Effects:
Orally: Belching, constipation, diarrhea, flatulence, and stomach upset.
Serious Adverse Effects (Rare):
Orally: Case reports have raised concerns about calciphylaxis and kidney stones.
Cardiovascular
...There has been concern that calcium intake may be associated with an increased risk of cardiovascular disease (CVD) and coronary heart disease (CHD), including myocardial infarction (MI).
Some clinical research suggests that calcium intake, often in amounts over the recommended daily intake level of 1000-1300 mg daily for adults, is associated with an increased risk of CVD, CHD, and MI (16118,17482,91350,107233). However, these results, particularly meta-analyses, have been criticized for excluding trials in which calcium was administered with vitamin D (94137). Many of these trials also only included postmenopausal females. Other analyses report conflicting results, and have not shown that calcium intake affects the risk of CVD, CHD, or MI (92994,93533,97308,107231). Reasons for these discrepancies are not entirely clear. It may relate to whether calcium is taken as monotherapy or in combination with vitamin D. When taken with vitamin D, which is commonly recommended, calcium supplementation does not appear to be associated with an increased risk of CVD, CHD, or MI (93533,107231). Also, the association between calcium supplementation and CVD, CHD, or MI risk may be influenced by the amount of calcium consumed as part of the diet. Supplementation with calcium may be associated with an increased risk of MI in people with dietary calcium intake above 805 mg daily, but not in those with dietary calcium intake below 805 mg daily (17482). To minimize the possible risk of CVD, CHD, or MI, advise patients not to consume more than the recommended daily intake of 1000-1200 mg and to consider total calcium intake from both dietary and supplemental sources (17484). While dietary intake of calcium is preferred over supplemental intake, advise patients who require calcium supplements to take calcium along with vitamin D, as this combination does not appear to be associated with an increased risk of MI (93533).
Rarely, calcium intake can increase the risk of calciphylaxis, which usually occurs in patients with kidney failure. Calciphylaxis is the deposition of calcium phosphate in arterioles, which causes skin ulcers and skin necrosis. In a case report, a 64-year-old female with a history of neck fracture, sepsis, and ischemic colitis presented with painful leg ulcers due to calciphylaxis. She discontinued calcium and vitamin D supplementation and was treated with sodium thiosulfate and supportive care (95816).
Gastrointestinal ...Orally, calcium can cause belching, flatulence, nausea, gastrointestinal discomfort, and diarrhea (1824,1843,12950,38803). Although constipation is frequently cited as an adverse effect of calcium, there is no scientific substantiation of this side effect (1824,1843,1844,1845,12950,38978). Calcium carbonate has been reported to cause acid rebound, but this is controversial (12935,12936).
Oncologic ...There is some concern that very high doses of calcium might increase the risk of prostate cancer. Some epidemiological evidence suggests that consuming over 2000 mg/day of dietary calcium might increase the risk for prostate cancer (4825,12949). Additional research suggests that calcium intake over 1500 mg/day might increase the risk of advanced prostate cancer and prostate cancer mortality (14132). Consumption of dairy products has also been weakly linked to a small increase in prostate cancer risk (98894). However, contradictory research suggests no association between dietary intake of calcium and overall prostate cancer risk (14131,14132,104630). More evidence is needed to determine the effect of calcium, if any, on prostate cancer risk.
Renal ...Kidney stones have been reported in individuals taking calcium carbonate 1500 mg daily in combination with vitamin D 2000 IU daily for 4 years (93943).
General
...Orally and topically, English ivy leaf extract seems to be generally well tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain, diarrhea, nausea, skin irritation, vomiting.
Topically: Allergic reactions, contact dermatitis.
Dermatologic
...Orally, English ivy and fresh English ivy leaves can cause skin irritation (7,29903).
Topically, fresh English ivy leaves can cause contact dermatitis and rash, with frequent exposure increasing the risk of sensitization (29910,29912,29913,29914,91301,96620,96636,96681). Occupational airborne exposure to English ivy can also cause contact dermatitis (96600).
Gastrointestinal ...Orally, English ivy can cause abdominal pain, diarrhea, nausea, and vomiting (29903,106055). The saponin constituents of English ivy can produce an acrid and/or bitter taste (7).
General
...Orally, thyme is well tolerated when used in food and seems to be well tolerated when used medicinally.
Topically, thyme seems to be generally well tolerated.
Most Common Adverse Effects:
Orally: Allergic reactions, diarrhea, dizziness, headache, heartburn, nausea, or vomiting.
Topically: Contact dermatitis and skin irritation.
Dermatologic ...Topically, thyme, thyme oil, or the constituent thymol can cause contact dermatitis and skin irritation (13463,78252,78362,78384,77982,78154,78310,78313,78384). In one study of 100 patients with contact allergies, 5% were attributed to thyme oil as an allergen contained in wound dressings (78362). Toothpastes containing thymol have been associated with cheilitis and glossitis (13463).
Gastrointestinal
...Orally, thyme and thyme oil may cause heartburn, nausea, vomiting, stomach upset, or diarrhea (13557,94033).
In a clinical study, two patients using extracts of thyme herb and ivy leaves experienced temporary stomach ache and mild nausea (78181).
Intravaginally, cream containing thyme and garlic has been associated with reports of nausea and vomiting in one clinical study (88387). It is not clear if these adverse effects were associated with thyme, garlic, or the combination.
Genitourinary ...Intravaginally, cream containing thyme and garlic has been associated with reports of vaginal dryness and vaginal irritation in one clinical study (88387). It is not clear if these adverse effects were associated with thyme, garlic, or the combination.
Immunologic ...Orally, thyme can cause allergic reactions; however, this is uncommon (13463). Allergic reactions to thyme might be more common in people who are also allergic to oregano and other Lamiaceae species (3808).
Neurologic/CNS ...Orally, thyme may case headache or dizziness (94033).
Pulmonary/Respiratory ...By inhalation, occupational exposure to thyme dust can cause acute airway obstruction (783,13463,13464,77982,78098).
