Vitafol-One should be used with caution in patients with known sensitivity or allergy to soy.
Vitamin D supplementation should be used with caution in those with hypercalcemia or conditions that may lead to hypercalcemia such as hyperparathyroidism and those who form calcium-containing kigney stones. High doses of vitamin D can lead to elevated levels of calcium that reside in the blood and soft tissues. Bone pain, high blood pressure, formation of kidney stones, renal failure, and increased risk of heart disease can occur.
Iodine should be used with caution in patients with an overactive thyroid.
Prolonged use of iron salts may produce iron storage disease.
Folic acid, especially in doses above 0.1 mg daily, may obscure pernicious anemia, in that hematologic remission may occur while neurological manifestations remain progressive.
The use of folic acid doses above 1 mg daily may precipitate or exacerbate the neurological damage of vitamin B12 deficiency.
Consumption of more than 3 grams of omega-3 fatty acids per day from all sources may lead to excessive bleeding. Supplemental intake of omega-3 fatty acids such as DHA exceeding 2 grams per day is not recommended.
Avoid Overdosage. Keep out of the reach of children.
Drug Interactions:
Medications for an overactive thyroid (anti-thyroid drugs) used in conjunction with iodine supplementation may lead to hypothyroidism.
Medications for hypertension used in conjunction with iodine supplementation may increase potassium.
High doses of folic acid may result in decreased serum levels of the anticonvulsant drugs;carbamazepine, fosphenytoin, phenytoin, phenobarbitol, valproic acid. Folic acid may decrease a patient's response to methotrexate.
Vitamin D supplementation should not be given with large amounts of calcium in those with hypercalcemia or conditions that may lead to hypercalcemia such as hyperparathyroidism and those who form calcium-containing kidney stones.
Zinc can inhibit the absorption of certain antibiotics; taken at least 2 hours apart to minimize interactions.
Consult appropriate references for additional specific vitamin-drug interactions.
Information for Patients: Patients should be counseled to disclose all medical conditions, including use of all medications, vitamins and supplements, pregnancy, and breast-feeding.
