Vitamin B6 weakens the effect of levodopa, prevents or reduces the severity of toxic manifestations, which are noted when using isoniazid and other anti-tuberculosis preparations.
Thiamine, influencing the polarization processes in the neuromuscular synapses, can weaken the curariform effect.
PASK, cimetidine, calcium preparations, alcohol reduce the absorption of vitamin B12.
Folic acid reduces plasma concentrations of phenytoin; with other antiepileptic preparations, a mutual decrease in clinical efficacy is possible.
Riboflavin is incompatible with streptomycin and reduces the effectiveness of antibacterial preparations (oxytetracycline, doxycycline, erythromycin, tetracycline and lincomycin).
The tricyclic antidepressants, imipramine and amitriptyline, inhibit riboflavin metabolism, especially in the heart tissue.
No cases of preparation overdose have been reported. in case of an overdose, allergic reactions (itching, skin flushing, skin rashes) and dyspeptic phenomena (nausea, vomiting, diarrhea, epigastric pain), changes in the skin and hair, liver dysfunction, headache, drowsiness, lethargy, facial flushing may occur , irritability.
