VITAMIN A

INDICATIONS:
Effective for

• Vitamin A deficiency. Taking vitamin A by mouth is effective for preventing and treating symptoms of vitamin A deficiency. Vitamin A deficiency can occur in people with protein deficiency, diabetes, over-active thyroid, fever, liver disease, cystic fibrosis, or an inherited disorder called abetalipoproteinemia.

Possibly Effective for

• Breast cancer. Premenopausal women with a family history of breast cancer who consume high levels of vitamin A in their diet seem to have lower risk of breast cancer. It is not known if taking vitamin A supplements has the same benefit.
• Cataracts.People who consume high amounts of vitamin A in their diet seem to have a lower risk of developing cataracts.
• Measles.Taking vitamin A by mouth seems to reduce the risk of measles complications or death in children with measles and vitamin A deficiency.
• Precancerous lesions in the mouth (oral leukoplakia).Research shows that taking vitamin A can help treat precancerous lesions in the mouth.
• Diarrhea after giving birth.Taking vitamin A, during, and after pregancy reduces diarrhea after giving birth in malnourished women.
• Pregnancy-related death.Taking vitamin A before and during pregnancy seems to reduce the risk of death by 40% in malnourished women.
• Pregnancy-related nightblindness.Taking vitamin A during pregnancy seems to reduce nightblindness by 37% in malnourished women. Vitamin A might work better for this condition when taken with zinc.
• Eye disease affecting the retina (retinitis pigmentosa).Taking vitamin A can slow the progression of an eye disease that causes damage to the retina.

WARNING &PRECAUTIONS:
Warnings
Avoid use if hypersensitivity, intravenous use, hypervitaminosis A, malabsorption syndrome (oral therapy), and pregnancy (recommended daily average).
This medication contains vitamin A. Do not take Retinol, Aquasol A, Retinyl Acetate, or Retinyl Palmitate if you are allergic to vitamin A or any ingredients contained in this drug.
Keep out of reach of children. In case of overdose, get medical help or contact a Poison Control Center immediately.

• Use caution if dose exceeds 25,000 units per day, monitor closely
• Evaluate additional vitamin deficiencies if diagnosis of vitamin deficiency occurs (single vitamin A deficiency rare)
• Monitor prolonged administration over 25,000 units per day, take into account vitamin intake from other dietary and supplement sources
• Efficacy of large systemic doses of 100,000 to 300,000 units per day of vitamin A for the treatment of acne is not established

PREGNANCY& LACTATION:

• Oral vitamin A use during pregnancy is generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk
• Use vitamin A (doses exceeding recommended daily average) during pregnancy with caution if benefits outweigh risks. Animal studies show risk and human studies are not available, or neither animal nor human studies were done
• If the vitamin A dose is greater than 6,000 units per day, administered parentally, do not use vitamin A during pregnancy. The risk involved outweighs potential benefits. Safer alternatives exist
• Breastfeeding: vitamin A is distributed into breastmilk, safe at recommended daily average levels

DRUG INTERACTION:
Calcium Carbonate; Risedronate: (Minor) Doses in excess of 1,500 to 2,000 mcg per day of Vitamin A may lead to bone loss and will counteract the effects of risedronate therapy.
Calcium: (Minor) Doses in excess of 1,500 to 2,000 mcg per day of Vitamin A may lead to bone loss and will counteract the effects of supplementation with calcium salts.
Castor Oil: (Moderate) Absorption of fat-soluble vitamins may be decreased with coadministration of castor oil.

Cholestyramine: (Moderate) Cholestyramine can decrease the intestinal absorption of fat and fat-soluble vitamins. If used concurrently, administration of the two agents should be staggered for the longest time interval possible.

Cod Liver Oil: (Severe) Patients should avoid or limit supplementation with vitamin A during treatment with retinoids to avoid potential additive toxic effects.
Colesevelam: (Moderate) It is not known if colesevelam can reduce the absorption of oral vitamin supplements including fat soluble vitamins A, D, E, and K. To minimize potential interactions, administer vitamins at least 4 hours before colesevelam.
Colestipol: (Moderate) Separate administration of fat-soluble vitamins by 1 hour before or 4 hours after a colestipol dose to limit effects on oral absorption. Because it sequesters bile acids, colestipol may interfere with normal fat absorption and thus may reduce absorption of fat-soluble vitamins.
Methoxsalen: (Moderate) Use methoxsalen and retinoids together with caution; the risk of severe burns/phototoxicity may be additive. If concurrent use is necessary, closely monitor patients for signs or symptoms of skin toxicity.

SIDE EFFECT:
