vitamin B12 1 MG/ML Injectable Solution

Dosage and administration

Avoid using the intravenous route. Use of this product intravenously will result in almost all of the vitamin being lost in the urine. Pernicious Anemia Parenteral vitamin B 12 is the recommended treatment and will be required for the remainder of the patient's life. The oral form is not dependable. A dose of 100 mcg daily for 6 or 7 days should be administered by intramuscular or deep subcutaneous injection. If there is clinical improvement and if a reticulocyte response is observed, the same amount may be given on alternate days for seven doses, then every 3 to 4 days for another 2 to 3 weeks. By this time hematologic values should have become normal. This regimen should be followed by 100 mcg monthly for life. Folic acid should be administered concomitantly if needed. Patients with Normal Intestinal Absorption Where the oral route is not deemed adequate, initial treatment similar to that for patients with pernicious anemia may be indicated depending on the severity of the deficiency. Chronic treatment should be with an oral B 12 preparation. If other vitamin deficiencies are present, they should be treated. Schilling Test The flushing dose is 1,000 mcg. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
