Special precautions for storage

Special warnings

Special precautions for use in animals:

Young animals, in which the process of renal elimination of gentamicin is slower than in adult animals, are more susceptible to the toxic effect of the drug.

Use half the recommended doses in animals aged up to two weeks.

The product should be used on the basis of results of resistance tests for bacteria isolated from sick animals. If this is impossible, treatment should be performed on the basis of local epidemiological information concerning sensitivity of isolated bacteria. If the condition of an animal requires longer administration of the drug, monitoring the condition of the kidneys is recommended through concentrations control of urea and creatinine in the blood serum.


Special precautions for persons administering the medicinal veterinary product to animals:

The product may have a sensitising effect on the skin causing contact dermatitis. During administration of the drug, protective clothing should be worn and special caution should be exercised. On accidental contact with the drug, the solution should be washed from the skin or the mucous membranes immediately. In the case of a self-injection, a hypersensitivity reaction may occur. After accidental self-injection, immediately seek medical help and show the information leaflet or the package to the physician.



Do not use throughout pregnancy.


Due to the nephrotoxic effect, use carefully in lactation only when the benefit for the mother exceeds the potential risk for the newborn animals.


Interaction with other medicinal products and other forms of interaction

Gentamicin displays cross-resistance with other amino glycosides. It has a synergic effect with β-lactam antibiotics (especially ampicillin and benzyl penicillin) on enterococci, staphylococci and streptococci. It also has a synergic effect with vancomycin and rifampicin on streptococci and staphylococci. Cephalosporins and some diuretics intensify nephrotoxicity and ototoxicity of the drug. Therefore, the drug cannot be administered in combination with cephalotin, cephaloridine, etacrynic acid, mannitol and furosemide. Its simultaneous use with vancomycin intensifies nephrotoxicity of both drugs. A combination with cisplatin reduces excretion of gentamicin thus posing a risk of nephrotoxicity and hypomagnaesemia. The preparation should not be mixed with solutions of penicillins with a wide spectrum because it may lead to inactivation of amino glycoside. The simultaneous use with amphotericin B, cyclosporine, cisplatin, methoxyflurane, acyclovir and non-steroid anti-inflammatory drugs may result in renal damage. Gentamicin administered in general anaesthesia in combination with cyclopropane may cause apnoea.


Overdose (symptoms, procedures concerning immediate help and antidotes):

After gentamicin overdose, functional disorders of the kidneys, neuromuscular block, impaired hearing may occur. In such a case, the administration of the drug should be discontinued.


Pharmaceutical incompatibilities:

Do not use with other antibiotics, strong diuretics and potentially nephrotoxic and ototoxic drugs.

Do not combine with anaesthetics or myorelaxants.
