It is an association of the water-soluble vitamins of the B complex: thiamine (vitamin B1), pyridoxine (vitamin B6), and cyanocobalamin (vitamin B12) for oral administration.
Vitamins are essential nutrients that intervene in numerous human metabolic processes.
It is indicated in: Prevention and treatment of deficiency states of vitamins B1, B6, and B12 due to increased needs, reduced consumption, or reduced absorption, which could manifest as cases of back pain, during convalescence, or insufficient diets.
Benexol B1-B6-B12 is indicated for adults and adolescents over 14 years of age.
2. What you need to know before taking Benexol B1-B6-B12 tablets.
Do not takeBenexol B1-B6-B12 tablets:
- if you are allergic to the active ingredients, to cobalamins (e.g., hydroxocobalamin), to cobalt, or to any of the other components of the medication (listed in section 6).
- if you are being treated with levodopa (a medication used in Parkinson's disease).
- it should not be administered to patients with Leber's disease (hereditary optic nerve atrophy) or with tobacco amblyopia (decreased visual acuity that can occur in people who abuse tobacco), as they may worsen.
Due to the doses it contains, do not take this medication:
- if you have kidney or liver disease.
- if you are pregnant or breastfeeding.
- children under 14 years of age.
Warnings and precautions
Consult your doctor, pharmacist, or nurse before starting to take Benexol B1-B6-B12 tablets.
- Do not take a higher dose than recommended or for a longer period than recommended. When high doses of pyridoxine (vitamin B6) are administered continuously, adverse effects of a neurological type (headache, tingling sensation, etc.) may occur.
- If you suffer from a blood disease, such as anemia, your doctor should check its cause before taking vitamin B12.
- If you have a predisposition to suffer from gout, you should be cautious because it could be produced due to the content of vitamin B12.
- If you have conditions such as uremia (accumulation of urea in the blood), infections, iron or folic acid deficiency, or are being treated with medications that have a suppressive effect on the bone marrow (e.g., chloramphenicol), the effect of vitamin B12 may decrease.
- Cases of dependence and withdrawal have been reported when taking doses of 200 mg of pyridoxine for a month.
- You should be cautious with the sun or avoid exposure to it, as pyridoxine can produce photosensitivity, with the appearance of a skin rash.
- If you have previously suffered from an allergy to vitamin B1 on skin contact (contact dermatitis) for professional reasons, you may suffer a relapse when taking this medication.
- Interference with analytical tests: If you are going to undergo any diagnostic test (including blood tests, urine tests, skin tests that use allergens, etc.), inform your doctor that you are taking this medication, as it may alter the results. In some determinations of urobilinogen, theophylline, uric acid, or antibodies against the intrinsic factor (FI), false results may occur.

Benexol B1-B6-B12 may interact with the following medications:
- Levodopa (medication for Parkinson's disease): may decrease its effect.
- Phenobarbital, phenytoin (medications for epilepsy).
- Amiodarone (for the heart).
- Altretamine (for cancer treatment).

- Several medications may decrease the absorption of cyanocobalamin (vitamin B12) or reduce its effect, such as: ascorbic acid (vitamin C) in high doses, aminoglycoside antibiotics such as neomycin, colchicine (for gout treatment), H2 antagonists (medications against acidity or stomach ulcers, such as ranitidine, cimetidine, etc.), aminosalicylic acid (for intestinal diseases), proton pump inhibitors such as omeprazol (for stomach ulcers), epilepsy medications, metformin (for diabetes), sustained-release potassium preparations, or cobalt radiation. The need for vitamin B12 may be increased in patients receiving these medications.
- Chloramphenicol: may delay or interrupt the response to red blood cell formation to vitamin B12. Close monitoring of the blood count should be performed if this combination cannot be avoided.
- Oral contraceptives may reduce the levels of both vitamin B6 and vitamin B12.
