Tribedoce: The Ultimate Guide to Vitamin B12 Injections

When it comes to maintaining our health, the importance of vitamin B12 can’t be overstated. But what happens when you’re not getting enough from your diet?

Enter Tribedoce, a vitamin B injection sold in Mexico. This guide covers what it contains, what it is used for, how it is given and its possible side effects.

It is general information, not medical advice. A clinician should confirm a deficiency and decide on any injections.

What is Tribedoce?

Tribedoce is not plain vitamin B12. It is a Mexican brand that combines three B vitamins: B1 (thiamine), B6 (pyridoxine) and B12.

The Mexican PLM drug reference listing for Tribedoce injection gives each 2 mL ampule as 10 mg hydroxocobalamin (B12), 100 mg thiamine and 50 mg pyridoxine. Other Tribedoce versions and tablets exist, so check the label of the product you have.

While most people get their B12 from foods, there are situations where that just isn’t enough.

Why Use Tribedoce?

In Mexico, the Tribedoce injection is labeled for nerve-related pain, such as low back pain, sciatica, neuralgia and alcohol- or diabetes-related neuropathy.

Vitamin B12 shots in general are used to treat and prevent B12 deficiency, including deficiency from pernicious anemia, absorption problems or a strict vegan diet, according to MedlinePlus. For a proven B12 deficiency, doctors often use a B12-only injection.

Without enough vitamin B12, you risk anemia and nerve damage that can become permanent if it goes untreated.

Administration and Dosage

The injectable form is a liquid given into a muscle, usually by a healthcare professional. Its Mexican labeling lists 2 mL every 24 or 48 hours, but your clinician sets the dose and how long treatment lasts.

For B12-only injections, MedlinePlus describes daily shots for about a week, then less frequent shots, then monthly shots that may continue for life.

The Need for Regular Injections

If your deficiency comes from pernicious anemia or another absorption problem, B12 treatment is often lifelong. Stopping it can let anemia and nerve symptoms come back.

Don’t start, stop or change injections on your own. Talk to your doctor first.

Side Effects: What to Watch For

B12 injections can cause diarrhea and a feeling that your whole body is swollen. Rare but serious symptoms, such as muscle weakness, extreme thirst, chest or breathing problems, hives or trouble swallowing, need medical help right away.

The thiamine and pyridoxine in Tribedoce can add flushing, nausea, vomiting, rash and pain at the injection site. Severe allergic reactions, including anaphylaxis, are possible.

Large doses of vitamin B6 over time can cause numbness and trouble coordinating movement, per MedlinePlus. Tell your doctor about any other B vitamins or supplements you take.

Safety and Monitoring

The product’s labeling says not to use it if you are allergic to its ingredients, cobalt or cyanide, or if you have polycythemia vera. Regular doctor visits and lab tests help track how your body responds.

Keeping Track of Your Health

An often-overlooked aspect of using Tribedoce is maintaining a record of all your medications and supplements. This list is invaluable during doctor visits and emergencies.

Conclusion

Tribedoce is a B1, B6 and B12 combination injection used in Mexico, mainly for nerve-related pain. It is not the same as a plain B12 shot.

If you think you have low B12, see a clinician for blood tests and a diagnosis before using any injection.
