You cannot combine the medicine with fluoroquinolones .
Drugs that block tubular secretion due to a decrease in the concentration of nitrofurantoin in the urine reduce the degree of antimicrobial effect of the drug and also increase the concentration of this substance in the blood, which leads to increased toxicity of the drug.
The antibacterial effect of Furadonin decreases in alkaline urine. Therefore, there is no need to take this remedy in parallel with medications that increase urine pH.
The process of removing Furadonin from the body is reduced by sulfinpyrazone and probenecid , therefore, the simultaneous use of these drugs is undesirable.
Interaction with other drugs
It is prohibited to take the medicine together with fluoroquinolones.
The antimicrobial effect of the drug is reduced when taken simultaneously with antacid medications containing magnesium trisilicate and nalidixic acid.
Drugs that block tubular secretion also lead to a decrease in the pharmacological effect. They, with increasing concentrations of nitrofurantoin, can increase the toxicity of the drug.
The therapeutic effect of the antimicrobial drug is suppressed in alkaline urine. Therefore, it is forbidden to combine the medicine with other drugs that increase the pH of urine.
