SPECIAL INSTRUCTIONS

Before prescribing the drug, you need to collect an allergic medical history, especially with regard to beta-lactam antibiotics.
It should be borne in mind that it is possible to develop a cross-allergy between penicillins and cephalosporins. The drug is administered with caution to patients who have a history of allergic reactions to penicillin (should take into account the possibility of developing severe anaphylactic reactions, up to a lethal outcome).
In the first weeks of treatment, pseudomembranous colitis can develop, manifested by severe diarrhea.
If this situation develops, cefosin should be discontinued and appropriate therapy should be prescribed, including metronidazole and vancomycin inside.
When determining glucose in the urine by a non-enzymatic method (for example, by the method of Benedict), false-positive results are possible.

If the duration of therapy is more than 10 days, the peripheral blood picture should be monitored.

OVERDOSE

Symptoms: convulsions, encephalopathy (with the administration of the drug in large doses, especially in renal failure), tremor, increased excitability.

Treatment: symptomatic therapy.

DRUG INTERACTION

With the simultaneous use of Cefosin and nephrotoxic drugs (aminoglycoside antibiotics, "loop" diuretics, polymyxin B), nephrotoxic effect may be enhanced.Therefore, it is necessary to monitor the kidney function with the simultaneous use of these drugs.

With the simultaneous appointment of Cefosin with antiplatelet agents, NSAIDs increase the risk of bleeding.

When combined with cefosin drugs blocking tubular secretion, plasma concentrations of cefotaxime increase and its excretion slows down.

Simultaneous application of Cefosin with ethanol does not lead to the development of disulfiram-like reactions.

Pharmaceutical interaction

The solution of Cefosin is incompatible with solutions of other antibiotics in one syringe or dropper.
