Rubivite : Uses, Side Effects, Interactions & More

Why is this medication prescribed?

Rubivite (Cyanocobalamin injection) is used to treat and prevent a lack of vitamin B12 that may be caused by any of the following: pernicious anemia (lack of a natural substance needed to absorb vitamin B12 from the intestine); certain diseases, infections, or medications that decrease the amount of vitamin B12 absorbed from food; or a vegan diet (strict vegetarian diet that does not allow any animal products, including dairy products and eggs). Lack of vitamin B12 may cause anemia (condition in which the red blood cells do not bring enough oxygen to the organs) and permanent damage to the nerves. Rubivite also may be given as a test to see how well the body can absorb vitamin B12. Rubivite is in a class of medications called vitamins. Because it is injected straight into the bloodstream, it can be used to supply vitamin B12 to people who cannot absorb this vitamin through the intestine.

How should this medicine be used?

Rubivite (Cyanocobalamin injection) comes as a solution (liquid) to be injected into a muscle or just under the skin. It is usually injected by a healthcare provider in an office or clinic. You will probably receive Rubivite once a day for the first 6-7 days of your treatment. As your red blood cells return to normal, you will probably receive the medication every other day for 2 weeks, and then every 3-4 days for 2-3 weeks. After your anemia has been treated, you will probably receive the medication once a month to prevent your symptoms from coming back.

Rubivite will supply you with enough vitamin B12 only as long as you receive injections regularly. You may receive Rubivites every month for the rest of your life. Keep all appointments to receive Rubivites even if you feel well. If you stop receiving Rubivites, your anemia may return and your nerves may be damaged.

Rubivite is also sometimes used to treat inherited conditions that decrease the absorption of vitamin B12 from the intestine. Rubivite is also sometimes used to treat methylmalonic aciduria (an inherited disease in which the body cannot break down protein) and is sometimes given to unborn babies to prevent methylmalonic aciduria after birth. Talk to your doctor about the possible risks of using this drug for your condition.
