Insufficient reliable information available; avoid using.
POSSIBLY SAFE ...when used orally and appropriately. Various proteolytic enzymes have been safely used orally in clinical research (716,964,965,968,969,6252,6253,10622,11457,18281,18284) (91104,91105,91106,91111,96449). Side effects are typically mild to moderate and most often include gastrointestinal effects. See specific monographs for more detailed information related to the safety of individual proteolytic enzymes. ...when used topically and appropriately. Various proteolytic enzymes have been safely used topically in clinical research (67835,67843,67845,91113). Some proteolytic enzymes might cause allergic reactions when used topically. See specific monographs for more detailed information related to the safety of individual proteolytic enzymes.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
POSSIBLY SAFE ...when used orally and appropriately, short-term. Uva ursi has been used with apparent safety in doses of up to 3600 mg daily for 3-5 days (101815).
POSSIBLY UNSAFE ...when used orally long-term or in high doses. There is concern about the safety of long-term or high-dose use because of the hydroquinone content of uva ursi. Hydroquinone is thought to have mutagenic and carcinogenic effects (7). At high doses (around 20 grams of dried herb) it can cause convulsions, cyanosis, delirium, shortness of breath, and collapse. At very high doses (30 grams of dried herb or more) it can be fatal (4).
CHILDREN: POSSIBLY UNSAFE
when used orally by children.
Uva ursi contains hydroquinone and high tannin levels, which can cause severe liver problems in children (4,18); avoid using.
PREGNANCY: LIKELY UNSAFE
when used orally.
Uva ursi can have oxytocic effects, increasing the speed of labor (4,7,19); avoid using.
LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally or intramuscularly and appropriately. Vitamin A, as pre-formed vitamin A (retinol or retinyl ester), is safe in adults when taken in doses below the tolerable upper intake level (UL) of 10,000 IU (3000 mcg) per day (7135). Higher doses increase the risk of side effects. There is also growing concern that taking high doses of antioxidants such as vitamin A might do more harm than good. In an analysis of studies, taking vitamin A supplements alone or in combination with other antioxidants is associated with an increased risk of mortality from all causes (15305,90775). Keep in mind that vitamin A is available in two different forms: pre-formed vitamin A (retinol or retinyl ester) and provitamin A (carotenoids). The safety concerns associated with high vitamin A intake occur with pre-formed vitamin A only. Some supplements contain vitamin A in both pre-formed and provitamin A forms. For these supplements, the amount of pre-formed vitamin A should be used to determine if the amount of vitamin A is safe.
POSSIBLY SAFE ...when used topically and appropriately, short-term. Retinol 0.5% has been used on the skin daily for up to 12 weeks with apparent safety. No serious adverse effects have been reported in clinical trials (103671,103680).
POSSIBLY UNSAFE ...when used orally in high doses. Doses higher than the UL of 10,000 IU (3000 mcg) per day of pre-formed vitamin A (retinol or retinyl ester) might increase the risk of side effects (7135). While vitamin A 25,000 IU (as retinyl palmitate) daily for 6 months followed by 10,000 IU daily for 6 months has been used with apparent safety in one clinical trial (95052), prolonged use of excessive doses of vitamin A can cause significant side effects such as hypervitaminosis A. The risk for developing hypervitaminosis A is related to total cumulative dose of vitamin A rather than a specific daily dose (1467,1469). There is also concern that taking high doses of antioxidants such as vitamin A might do more harm than good. In an analysis of studies, taking vitamin A supplements alone or in combination with other antioxidants is associated with an increased risk of mortality from all causes (15305,90775). There is insufficient reliable information available about the safety of using sublingual formulations of vitamin A.
CHILDREN: LIKELY SAFE
when used orally or intramuscularly and appropriately.
The amount of pre-formed vitamin A (retinol or retinyl ester) that is safe depends on age. For children up to 3 years of age, doses less than 2000 IU (600 mcg) per day seem to be safe. For children ages 4 to 8, doses less than 3000 IU (900 mcg) per day seem to be safe. For children ages 9 to 13, doses less than 5667 IU (1700 mcg) per day seem to be safe. For children 14 to 18, doses less than 9333 IU (2800 mcg) per day seem to be safe (7135). Keep in mind that vitamin A is available in two different forms: pre-formed vitamin A (retinol or retinyl ester) and provitamin A (carotenoids). The safety concerns associated with high vitamin A intake occur with pre-formed vitamin A only. Some supplements contain vitamin A in both pre-formed and provitamin A forms. For these supplements, the amount of pre-formed vitamin A should be used to determine if the amount of vitamin A is safe.
CHILDREN: POSSIBLY UNSAFE
when pre-formed vitamin A (retinol or retinyl ester) is used orally in excessive doses.
For children up to 3 years of age, avoid doses greater than 2000 IU (600 mcg) per day. For children ages 4 to 8, avoid doses greater than 3000 IU (900 mcg) per day. For children ages 9 to 13, avoid doses greater than 5667 IU (1700 mcg) per day. For children ages 14 to 18, avoid doses greater than 9333 IU (2800 mcg) per day (7135). Higher doses of vitamin A supplementation have been associated with increased risk of side effects such as pneumonia, bone pain, and diarrhea (319,95051). Long-term supplementation with low to moderate doses on a regular basis can cause severe, but usually reversible, liver damage (11978).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally or intramuscularly and appropriately.
Vitamin A, as pre-formed vitamin A (retinol or retinyl ester), is safe during pregnancy and lactation when used in doses less than 10,000 IU (3000 mcg) per day (7135,16823,107293). Keep in mind that vitamin A is available in two different forms: pre-formed vitamin A (retinol or retinyl ester) and provitamin A (carotenoids). The safety concerns associated with high vitamin A intake occur with pre-formed vitamin A only. Some supplements contain vitamin A in both pre-formed and provitamin A forms. For these supplements, the amount of pre-formed vitamin A should be used to determine if the amount of vitamin A is safe.
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used orally or intramuscularly in excessive doses.
Daily intake of greater than 10,000 IU (3000 mcg) can cause fetal malformations (3066,7135). Excessive dietary intake of vitamin A has also been associated with teratogenicity (11978). The first trimester of pregnancy seems to be the critical period for susceptibility to vitamin A-associated birth defects such as craniofacial abnormalities and abnormalities of the central nervous system (7135). Pregnant patients should monitor their intake of pre-formed vitamin A (retinol or retinyl ester). This form of vitamin A is found in several foods including animal products, some fortified breakfast cereals, and dietary supplements (3066).

|
Theoretically, taking high doses of vitamin A in combination with other potentially hepatotoxic drugs might increase the risk of liver disease.
Details
|
Concomitant use of retinoids with vitamin A supplements might produce supratherapeutic vitamin A levels.
Details
Retinoids, which are vitamin A derivatives, could have additive toxic effects when taken with vitamin A supplements (3046).
|
Theoretically, taking tetracycline antibiotics with high doses of vitamin A can increase the risk of pseudotumor cerebri.
Details
Benign intracranial hypertension (pseudotumor cerebri) can occur with tetracyclines and with acute or chronic vitamin A toxicity. Case reports suggest that taking tetracyclines and vitamin A concurrently can increase the risk of this condition (10545,10546,10547). Avoid high doses of vitamin A in people taking tetracyclines chronically.
|
Theoretically, high doses of vitamin A could increase the risk of bleeding with warfarin.
Details
Vitamin A toxicity is associated with hemorrhage and hypoprothrombinemia, possibly due to vitamin K antagonism (505). Advise patients taking warfarin to avoid doses of vitamin A above the tolerable upper intake level of 10,000 IU/day for adults.

Orally: Gastrointestinal upset.
Serious Adverse Effects (Rare):
Topically: Allergic reactions.
Gastrointestinal ...Orally, some patients taking proteolytic enzymes may have gastrointestinal complaints (101517).
Immunologic ...Proteolytic enzymes are commonly found in laundry detergents and pre-spotter products. Rarely, protease specific IgE positive tests possibly related to these products have occurred. Exposure may be airborne or topical (102705). In addition, in case reports, occupational exposure to the airborne proteolytic enzyme pepsin has resulted in allergic rhinoconjunctivitis or asthma (102706,102707).
General
...Uva ursi is generally well tolerated in low doses, short-term.
Most Common Adverse Effects:
Orally: Diarrhea, nausea, stomach upset, and vomiting.
Serious Adverse Effects (Rare):
Orally: At high doses (20 grams of dried herb), uva ursi has been reported to cause collapse, convulsions, cyanosis, delirium, shortness of breath, and tinnitus. Very high doses of 30 grams or more may be fatal.
Gastrointestinal ...Orally, uva ursi may cause nausea, vomiting, diarrhea, and stomach upset (92148). It can also irritate the gastrointestinal tract (19).
Genitourinary ...Orally, uva ursi may cause the urine to be greenish-brown. It may also cause irritation and inflammation of the urinary tract mucous membranes (18).
Hepatic ...Uva ursi may be hepatotoxic. Theoretically, chronic use, especially in children, can cause liver impairment due its hydroquinone and high tannin content (4,18).
Neurologic/CNS ...Orally, around 20 grams of uva ursi is reported to supply up to one gram of hydroquinone, which can theoretically cause convulsions and delirium (4).
Ocular/Otic
...Orally, uva ursi may potentially cause retinal toxicity due to its hydroquinone content, which reduces melanin synthesis.
A 56-year-old female developed bilateral bull's-eye maculopathy, paracentral scotomas, and retinal thinning after 3 years of uva ursi tea ingestion (16900).
Taking around 20 grams of uva ursi orally is reported to supply up to one gram of hydroquinone, which can theoretically cause tinnitus (4).
Pulmonary/Respiratory ...Orally, around 20 grams of uva ursi is reported to supply up to one gram of hydroquinone, which can theoretically cause shortness of breath and cyanosis (4).
General
...Orally, vitamin A is generally well-tolerated at doses below the tolerable upper intake level (UL).
Serious Adverse Effects (Rare):
Orally: In very high doses, vitamin A can cause pseudotumor cerebri, pain, liver toxicity, coma, and even death.
Dermatologic ...Chronic oral use of large amounts of vitamin A causes symptoms of vitamin A toxicity including dry skin and lips; cracking, scaling, and itchy skin; skin redness and rash; hyperpigmentation; shiny skin, and massive skin peeling (7135,95051). Hypervitaminosis A can cause brittle nails, cheilitis, gingivitis, and hair loss (15,95051). Adverse effects from a single ingestion of a large dose of vitamin A is more common in young children than adults (15). In children, approximately 25,000 IU/kg can cause skin redness and generalized peeling of the skin a few days later and may last for several weeks (15).
Gastrointestinal ...There is some evidence that oral vitamin A supplementation might increase the risk of diarrhea in children. Although vitamin A can prevent diarrhea and reduce mortality in malnourished children, doses as low as 10,000 IU weekly for 40 weeks have been associated with diarrhea in well-nourished children (319). Diarrhea (82326,82389), nausea (7135,100329), abdominal pain (95051), abdominal fullness (100329), and vomiting (7135,82559,95051,95055,109755) have been reported following use of large doses of oral vitamin A. Adverse effects from a single ingestion of a large dose of vitamin A is more common in young children than adults (15). In children, approximately 25,000 IU/kg can cause vomiting and diarrhea (15). Chronic use of large amounts of vitamin A causes symptoms of vitamin A toxicity including anorexia, abdominal discomfort, and nausea and vomiting (7135).
Genitourinary ...Hypervitaminosis A can cause reduced menstrual flow (15). Intravaginally, all-trans retinoic acid can cause vaginal discharge, itching, irritation, and burning (9199).
Hematologic ...Hypervitaminosis A can cause spider angiomas, anemia, leukopenia, leukocytosis, and thrombocytopenia (15,95051).
Hepatic ...Since the liver is the main storage site for vitamin A, hypervitaminosis A can cause hepatotoxicity, with elevated liver enzymes such as alanine aminotransferase (ALT, formerly SGPT) and aspartate aminotransferase (AST, formerly SGOT), as well as fibrosis, cirrhosis, hepatomegaly, portal hypertension, and death (6377,7135,95051).
Musculoskeletal
...Vitamin A can increase the risk for osteoporosis and fractures.
Observational research has found that chronic, high intake of vitamin A 10,000 IU or more per day is associated with an increased risk of osteoporosis and hip fracture in postmenopausal adults, as well as overall risk of fracture in middle-aged males (7712,7713,9190). A meta-analysis of these and other large observational studies shows that high dietary intake of vitamin A or retinol is associated with a 23% to 29% greater risk of hip fracture when compared with low dietary intake (107294). High serum levels of vitamin A as retinol also increase the risk of fracture in males. Males with high serum retinol levels are seven times more likely to fracture a hip than those with lower serum retinol levels (9190). Vitamin A damage to bone can occur subclinically, without signs or symptoms of hypervitaminosis A. Some researchers are concerned that consumption of vitamin A fortified foods such as margarine and low-fat dairy products in addition to vitamin A or multivitamin supplements might cause excessive serum retinol levels. Older people have higher levels of vitamin A and might be at increased risk for vitamin A-induced osteoporosis.
Vitamin A's effects on bone resorption could lead to hypercalcemia (95051).
Hypervitaminosis can cause slow growth, premature epiphyseal closure, painful hyperostosis of the long bones, general joint pain, osteosclerosis, muscle pain, and calcium loss from the bones (15,95051). One child experienced severe bone pain after taking vitamin A 600,000 IU daily for more than 3 months (95051). Vitamin A was discontinued and symptoms lessened over a period of 2 weeks. The patient made a full recovery 2 months later.
Neurologic/CNS
...Orally, adverse effects from a single large dose of vitamin A are more common in young children than adults (15).
Headache, increased cerebrospinal fluid pressure, vertigo, and blurred vision have been reported following an acute oral dose of vitamin A 500,000 IU (7135). In children, approximately 25,000 IU/kg can cause headache, irritability, drowsiness, dizziness, delirium, and coma (15). Chronic use of large amounts of vitamin A causes symptoms of vitamin A toxicity including fatigue, malaise, lethargy, and irritability (7135).
There are reports of bulging of the anterior fontanelle associated with an acute high oral dose of vitamin A in infants (7135,90784,95053,95054). In children, approximately 25,000 IU/kg can cause increased intracranial pressure with bulging fontanelles in infants (15). Also, muscular incoordination has been reported following short-term high doses of vitamin A (7135).
A case of intracranial hypertension involving diffuse headaches and brief loss of vision has been reported secondary to topical use of vitamin A. The patient was using over-the-counter vitamin A preparations twice daily including Avotin 0.05% cream, Retin-A gel 0.01%, and Isotrexin gel containing isotretinoin 0.05% and erythromycin 2%, for treatment of facial acne. Upon exam, the patient was noted to have bilateral optic disc edema. The patient discontinued use of topical vitamin A products. Two months later, the patient reported decreased headaches and an improvement in bilateral optic disc edema was seen (95056).
Ocular/Otic ...In children, oral vitamin A approximately 25,000 IU/kg can cause swelling of the optic disk, bulging eyeballs, and visual disturbances (15). Adverse effects from a single ingestion of a large dose of vitamin A are more common in young children than adults (15).
Oncologic ...There is concern that high intake of vitamin A might increase some forms of cancer. Population research suggests high vitamin A intake might increase the risk of gastric carcinoma (9194).
Psychiatric ...Chronic oral use of large amounts of vitamin A causes symptoms of vitamin A toxicity, which can include symptoms that mimic severe depression or schizophrenic disorder (7135).
Pulmonary/Respiratory ...There is some evidence that oral vitamin A supplementation might increase the risk of pneumonia and diarrhea in children. Although vitamin A can prevent diarrhea and reduce mortality in malnourished children, doses as low as 10,000 IU weekly for 40 weeks have been associated with pneumonia and diarrhea in well-nourished children (319). In preschool children, high-dose vitamin A also increases the risk of respiratory infection (82288).
Other ...Chronic use of large amounts of vitamin A (>25,000 IU daily for more than 6 years or 100,000 IU daily for more than 6 months) can cause symptoms of vitamin A toxicity including mild fever and excessive sweating (7135). High intakes of vitamin A may result in a failure to gain weight normally in children and weight loss in adults (15).
