Vitamin B12 Injection

Vitamin B12 injections are typically recommended when you have a deficiency or if your body is unable to absorb B12 from food, such as in cases of pernicious anemia or certain gastrointestinal conditions.

The course depends on the severity of the deficiency. Initially, you may receive a series of injections, often one per week, for a few weeks, followed by maintenance injections every 1-3 months.

Maintenance doses are recommended every 1–3 months depending on individual needs.

An injection, usually in the muscle (intramuscular) or under the skin (subcutaneous).

Side effects are rare but may include soreness at the injection site, dizziness, or a mild rash.

The injection is suitable for children with a diagnosed B12 deficiency. The frequency and dosage depend on the child's needs.

People with a history of certain conditions (such as kidney disease) should consult a healthcare provider before receiving B12 injections.

A deficiency can lead to fatigue, weakness, nerve damage, anemia, and cognitive issues such as memory loss and mood changes. In severe cases, untreated deficiency can cause irreversible nerve damage.
