VP-GGR-B6 should be administered under the supervision of a licensed medical practitioner.
Each round, pink tablet contains the following dietary ingredients:
|
|
|
|
Vitamin B6 (pyridoxine HCl) |
40 mg |
|
Folic Acid |
1.2 mg |
|
Calcium (as dicalcium phosphate and tricalcium phosphate) |
124.1 mg |
|
100 mg* |
Other Ingredients: Acacia, Citric Acid, Magnesium Stearate, Microcrystalline Cellulose, Pink Coating (FD&C Red#40 Lake, Hydroxypropylmethyl Cellulose, Polyethylene Glycol, Polyvinyl Alcohol, Talc, Titanium Dioxide), Polyvinylpyrrolidone, Silicified Microcrystalline Cellulose, Stearic Acid, and TriPotassium Citrate
Since colors, flavors of natural origin vary from batch to batch in consistency - it may be necessary to substitute excipients as needed to ensure the highest therapeutic target, safety and quality.
Daily Values not established for patients with unique nutritional needs who are in need of supplementation as directed by a licensed medical practitioner.
FOLATE REGULATION: The term "folate" are B vitamins that include folic acid and any forms of active pteroylglutamates regardless of the reduction state of the molecule. Folates, or vitamin B9, are primarily hydrolyzed in the intestinal jejunum and the liver to the active circulating form of folate, l-methylfolate, with an intermediate stable form, 5,10-methylenetetrahydrofolate.
Individuals with genetic polymorphisms for the genes coding methylenetetrahydrofolate reductase (MTHFR) may not be capable of utilizing or metabolizing folic acid adequately for the vitamin B12 dependent methylation cycle.
Folic acid, including reduced forms1 such as folinic acid, may obscure pernicious anemia above 0.1 mg doses, and must be administered under the supervision of a licensed medical practitioner.
The 1971, 1972, 1973, 1980, 1984, 2000, and 2010 Federal Register Notices addressed this concern while establishing that increased folate was proper therapy in megaloblastic anemias - specifically where homocysteine levels were elevated or risk of neural tube defects (NTDs) was at issue. The Federal Register Notice of August 2, 1973 (38 FR 20750) specifically states that:
- Dietary supplement preparations are available without a prescription (21 CFR 121.1134). Levels higher than dietary supplement amounts are available only with a prescription.
Folic acid - including reduced forms, may be added to medical foods as defined in section 5(b)(3) of the Orphan Drug Act (21 USC 360ee(b)(3)), or to food (21 CFR 172.345).
INDICATIONS AND USAGE: VP-GGR-B6 is indicated for the distinct nutritional requirements of patients in need of PRENATAL dietary supplementation as determined by a licensed medical practitioner.
VP-GGR-B6 should be administered under the supervision of a licensed medical practitioner.
CONTRAINDICATIONS: This product is contraindicated in patients with a known hypersensitivity to any of the ingredients.
WARNINGS: VP-GGR-B6 contains ginger. Ginger may increase the risk of bleeding in certain situations. Individuals with bleeding disorders and/or those receiving anti-coagulant therapy or anti-platelet therapy should ask their licensed medical practitioner before using this product. In addition, those individuals undergoing surgery should seek advice of their medical practitioner.
Individuals with cardiac conditions, gallstones, diabetes and/or hypoglycemia should consult their medical practitioner before taking this product.
See product ingredients. Please consult your healthcare practitioner or pharmacist for more information.
PRECAUTIONS: General: Folate, when administered as a single agent in doses about 0.1 mg daily, may obscure the detection of vitamin B12 deficiency (specifically, the administration of folic acid may reverse the hematological manifestations of B12 deficiency, including pernicious anemia, while not addressing the neurological manifestations). Folate therapy alone is inadequate for treatment of a vitamin B12 deficiency.
PATIENT INFORMATION: VP-GGR-B6 is a PRENATAL prescription folate to be used only under licensed medical supervision.
DRUG INTERACTIONS: Drugs which may interact with folate** include:
- Antiepileptic drugs (AED): The AED class including, but not limited to, phenytoin, carbamazepine, primidone, valproic acid, fosphenytoin, valproate, phenobarbital and lamotrigine have been shown to impair folate absorption and increase the metabolism of circulating folate.
- Additionally, concurrent use of folic acid has been associated with enhanced phenytoin metabolism, lowering the level of the AED in the blood and allowing breakthrough seizures to occur. Caution should be used when prescribing this product among patients who are receiving treatment with phenytoin and other anticonvulsants.
- Capecitabine: Folinic acid (5-formyltetrahydrofolate) may increase the toxicity of Capecitabine.
- Cholestyramine: Reduces folic acid absorption and reduces serum folate levels.
- Colestipol: Reduces folic acid absorption and reduces serum folate levels.
- Cycloserine: Reduces folic acid absorption and reduces serum folate levels.
- Dihydrofolate Reductase Inhibitors (DHFRI): DHFRIs block the conversion of folic acid to its active forms, and lower plasma and red blood cell folate levels. DHFRIs include aminopterin, methotrexate, pyrimethamine, triamterene, and trimethoprim.
- Fluoxetine: Fluoxetine exerts a noncompetitive inhibition of the 5-methyltetrahydrofolate active transport in the intestine.
- Isotretinoin: Reduced folate levels have occurred in some patients taking isotretinoin.
- L-dopa, triamterene, colchicine, and trimethoprim may decrease plasma folate levels.
- Nonsteroidal Anti-inflammatory Drugs (NSAIDs):
- NSAIDs have been shown to inhibit some folate dependent enzymes in laboratory experiments.
- NSAIDs include ibuprofen, naproxen, indomethacin and sulindac.
- Oral Contraceptives: Serum folate levels may be depressed by oral contraceptive therapy.
- Methylprednisolone: Reduced serum folate levels have been noted after treatment with methylprednisolone.
- Pancreatic Enzymes: Reduced folate levels have occurred in some patients taking pancreatic extracts, such as pancreatin and pancrelipase.
- Pentamidine: Reduced folate levels have been seen with prolonged intravenous pentamidine.
- Pyrimethamine: High levels of folic acid may result in decreased serum levels of pyrimethamine.
- Smoking and Alcohol: Reduced serum folate levels have been noted.
- Sulfasalazine: Inhibits the absorption and metabolism of folic acid.
- Metformin treatment in patients with type 2 diabetes decreases serum folate.
- Warfarin can produce significant impairment in folate status after a 6-month therapy.
- Heme-iron: Can compete for transport and reduce folate absorption. Ensure adequate medical supervision to ensure proper iron levels.
- Folinic acid may enhance the toxicity of fluorouracil.
- Concurrent administration of chloramphenicol and folinic acid in folate-deficient patients may result in antagonism of the haematopoietic response to folate.
- Caution should be exercised with the concomitant use of folinic acid and trimethoprim-sulfamethoxazole for the acute treatment of Pneumocystis carinii pneumonia in patients with HIV infection as it is associated with increased rates of treatment failure and mortality in a placebo controlled study.
** Folate is a broad term that includes folic acid and all reduced forms including l-methylfolate and folinic acid. VP-GGR-B6 does not contain l-methylfolate or folinic acid but these warnings are included as general folate information.
Drugs which interact with vitamin B6:
- Vitamin B6 should not be given to patients receiving the drug levodopa because the action of levodopa is antagonized by vitamin B6. However, vitamin B6 may be used concurrently in patients receiving a preparation containing both carbidopa and levodopa.
- Isoniazid can produce a vitamin B6 deficiency.
Drugs which interact with calcium:
- Calcium may interfere with the absorption of iron. Consult your healthcare practitioner for advice.
- Calcium may interfere with blood pressure medications in certain situations. Consult your healthcare practitioner for advice.
ADVERSE REACTIONS: Allergic sensitization has been reported following both oral and parental administration of folic acid, and may possibly occur with other forms of folate. Paresthesia, somnolence, nausea and headaches have been reported with vitamin B6. Gas, bloating, heartburn, and nausea have been associated with ginger, but normally with high doses.
DOSAGE AND ADMINISTRATION: One or two tablets daily, in divided doses, or as directed by a licensed medical practitioner.
STORAGE: Store at Controlled Room Temperature 15°-30°C (59°-86°F). [See USP]. Protect from light and moisture. Dispense in a tight, light-resistant container.
HOW SUPPLIED: VP-GGR-B6 is supplied as round, pink tablets debossed on one side with “V233”, dispensed in bottles of 60 tablets.
