Overview

Dibencozide is a form of vitamin B12. People use it as medicine.

When taken by mouth or placed under the tongue, dibencozide is used to help the body process protein; increase muscle mass and strength; improve mental concentration; and to treat depression, anxiety, and panic attacks.

How does it work?

Dibencozide is a form of vitamin B12. Vitamin B12 is important in chemical reactions throughout the body. However, dibencozide is not as stable as cyanocobalamin, the form of vitamin B12 most often found in vitamin tablets, and may break down during storage.

Uses & Effectiveness

Insufficient Evidence to Rate Effectiveness for...

  • Helping the body process protein.
  • Increasing muscle mass and strength.
  • Improving mental concentration.
  • Depression.
  • Anxiety.
  • Panic attacks.
  • Other conditions.
More evidence is needed to rate the effectiveness of dibencozide for these uses.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).

Side Effects

Dibencozide seems to be safe for most people. There are no reported side effects.

Special Precautions & Warnings

Pregnancy and breast-feeding: Not enough is known about the use of dibencozide during pregnancy and breast-feeding. Stay on the safe side and avoid use.

Gastrointestinal (GI) conditions: Some GI conditions, such as ileal disease or surgical removal of part of the intestine, can reduce that amount of Vitamin B12, including dibencozide, that is absorbed from the intestine.

Interactions


ChloramphenicolInteraction Rating: Moderate Be cautious with this combination.Talk with your health provider.

Dibencozide is a form of vitamin B12. Vitamin B12 is important for producing new blood cells. Chloramphenicol might decrease new blood cells. Taking chloramphenicol for a long time might decrease the effects of dibencozide on new blood cells. But most people only take chloramphenicol for a short time so this interaction isn't a big problem.

Dosing

The appropriate dose of dibencozide depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for dibencozide. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
