Drug Interactions


Means that alkalize the urine (for example, sodium bicarbonate) reduce the therapeutic effect of furagin (accelerate the excretion of furagin in the urine). Means that acidify urine (acids, including ascorbic acid, as well as calcium chloride), increase the concentration of furagin in the urine (its excretion with urine slows down), thus increasing the therapeutic effect of the drug, but at the same time increasing the risk of developing toxic effects.

Aminoglycoside antibiotics and tetracycline enhance the antibacterial effect of furagin. In combination with chloramphenicol and ristomycin, the risk of hemotoxic events increases.

Antagonism of action with nalidixic acid (weakens the bacteriostatic effect of furagin).

With the simultaneous use of furagin and uricosuric agents (probenecid, sulfinpyrazone), the excretion of furagin in the urine decreases, which leads to cumulation of furagin and the possibility of developing toxic effects.

With the simultaneous use of furagin and antacids containing magnesium trisilicate, the absorption of furagin decreases.

Atropine slows down the absorption of furagin, but the total amount of absorbed drug does not change.

 

Special instructions


Precautionary measures

Caution should be observed in patients with impaired renal function, with anemia, deficiency of B vitamins and folic acid, with lung diseases (in patients over 65 years of age). With prolonged use of furagin inside, neuritis may develop. In the case of long-term therapy, lung and liver function should be monitored, especially in patients over 65 years of age. With caution, furagin should be used in patients with diabetes mellitus, tk. the drug may contribute to the development of polyneuropathy.

A laboratory study of patients taking furagin may give a false-positive reaction for the presence of glucose in the urine if the copper reduction method is used for determination. Furagin has no effect on the results of determining glucose in the urine, performed by the enzymatic method. In the case of long-term use of furagin, the number of leukocytes in the blood, as well as indicators of liver and kidney function, should be periodically monitored to avoid the development of undesirable side effects.

Use is contraindicated in persons with hereditary fructose intolerance, deficiency of the Lapp-lactase enzyme, malabsorption of glucose-galactose.


Overdose


Toxic effects are possible in patients with impaired renal function.

Symptoms: headache, dizziness, depression, peripheral polyneuritis, allergic reactions (urticaria, angioedema, bronchospasm), nausea, vomiting, hemolytic anemia (in persons with glucose-6-phosphate dehydrogenase deficiency), megaloblastic anemia.

Treatment: gastric lavage, intravenous infusion solution (0.9% sodium chloride solution). Providing symptomatic and supportive therapy. In severe cases, hemodialysis is indicated. The specific antidote is not known.
