  • Regular excessive alcohol consumption.
  • Prolonged infection.
  • Intestinal diseases, such as celiac disease or persistent diarrhea.
  • High carbohydrate intake.
  • Poor nutritional status.

Treatment of beriberi (characterized by intense fatigue and slow movement, affecting mainly the nervous and cardiovascular systems), Wernicke's disease (affecting the nervous system), and Korsakoff's syndrome (caused by excessive alcohol consumption, with effects on the brain).

2. What you need to know before using Benerva injectable solution

Do not use Benerva

  • if you are allergic to thiamine (vitamin B1) or any of the other components of this medicine (listed in section 6).

Warnings and precautions

Consult your doctor or pharmacist before starting to use Benerva injectable solution.

The risk of hypersensitivity reactions increases with repeated intravenous or intramuscular administration of thiamine. Therefore, when possible, oral administration is recommended. In this case, another medicine with the active ingredient administered orally would be preferable.

Administer intravenously only by a healthcare professional. The administration of the product and the handling of needles must be done with caution.

If you have previously suffered from an allergy to vitamin B1 on skin contact (contact dermatitis) for professional reasons, for example, you may experience a relapse when treated with this medicine.

Interference with laboratory tests: If you are going to undergo any diagnostic test (including blood, urine, etc.), inform your doctor that you are being treated with this medicine, as it may alter the results. In some determinations of uric acid, urobilinogen, or theophylline, false results may occur.

Children

Do not use this medicine in children, as there is no data available for them.

Other medicines and Benerva injectable solution

Inform your doctor or pharmacist if you are taking/using, have recently taken/used, or may need to take/use any other medicine.

3. How to use Benerva injectable solution

Follow exactly the administration instructions of this medicine indicated by your doctor.

In case of doubt, consult your doctor again.

Intramuscularly, or by slow intravenous injection or short-duration perfusion.

The contents of the ampoule should not be mixed with any other parenteral product or injection fluid. The injection should be administered by a qualified healthcare professional.

The recommended dose is:

  • Adults:

50 mg (half an ampoule) of vitamin B1 should be administered daily by intramuscular injection for several days when absorption is significantly affected and also for the treatment of Wernicke-Korsakoff syndrome and beriberi.

For the initial treatment of vitamin B1 deficiency or severe hypovitaminosis B1, the initial daily dose may be 100 mg or up to 200 mg by parenteral route, for example, intramuscularly or by slow intravenous injection or even by short-duration perfusion, to achieve an adequate blood concentration of vitamin B1 as quickly as possible.

For Wernicke-Korsakoff syndrome due to alcohol abuse, the usual dose is 100 mg by intravenous injection followed by 50-100 mg by intramuscular injection daily until the patient consumes a balanced diet.

For emergency treatment, 100 mg (or 200 mg if necessary, or up to 1000 mg in the first 12 hours if necessary) by slow intravenous injection daily for three days.

Intramuscular administration can be used if intravenous administration is not possible. Treatment can be continued with 100 mg of thiamine orally.
