BARS ear drops

0.5/0.3 mg/ml, 20 ml for dogs and cats
Assessed clinical scopeDog · Full dog label: ear mite infestation (otodectosis) with ear inflammation, 3-5 drops per ear of an organophosphate acaricide with prednisolone, two treatments 5-7 days apart · auricular
Care settingOwner treatment of both ears and all in-contact animals after veterinary confirmation of ear mites
vetman score 4.6/10 Weak evidence support
Evidence confidence: Low Georgia: Yes, veterinary · № 001146 · Verified on 21 Oct 2026

A weak option for ear mites: an organophosphate ear drop with no independent efficacy data and a short course. Authorised modern acaricides are more reliable and avoid organophosphate exposure.

Regulatory and scientific credibility4.0/10

The exact product is registered in Georgia (001146, valid to 2031) with a current AVZ instruction; diazinon has no EU, UK or US authorisation documented in the reviewed evidence for pets and efficacy rests on manufacturer material, so the evidence gate caps credibility at 4.

Clinical efficacy4.5/10

Diazinon is acaricidal and prednisolone reduces inflammation, but no independent trial supports this product, two treatments 5-7 days apart may not cover the three-week mite life cycle, and ESCCAP favours authorised modern acaricides.

Safety and tolerability4.5/10

Diazinon is an organophosphate cholinesterase inhibitor: the low ear dose limits exposure, but licking, overdose or combination with other acaricides can poison; the label excludes a perforated eardrum, pregnancy and puppies under 4 weeks.

Clinical practicality6.0/10

Two short treatments of 3-5 drops per ear are easy at home, but both ears and every in-contact dog and cat need treatment.

Full-course cost-effectiveness-

No verified current Georgian price or patient-adjusted course cost was found; foreign prices were not substituted.

Important safety and use flags

  • Do not use with a perforated eardrum, during pregnancy, in puppies under 4 weeks, or together with another acaricide or cholinesterase inhibitor.
  • Organophosphate poisoning causes drooling, tremor, small pupils, vomiting and diarrhoea; stop and treat as an emergency (atropine).
  • Treat all in-contact dogs and cats and continue until mites are gone; an authorised modern acaricide is usually more reliable.
  • Clean the ears first and recheck by otoscopy or microscopy after the course.
  • Use during lactation only for vital indications under veterinary supervision.

Evidence confidence: Low Georgia: Yes, veterinary · № 001146 · Verified on 21 Oct 2026

A weak option for cats: an organophosphate ear drop in a species sensitive to organophosphates, without independent efficacy data. Authorised feline acaricides are safer and more reliable.

Regulatory and scientific credibility4.0/10

The exact product is registered in Georgia (001146, valid to 2031) with a current AVZ instruction; diazinon has no EU, UK or US authorisation documented in the reviewed evidence for pets and efficacy rests on manufacturer material, so the evidence gate caps credibility at 4.

Clinical efficacy4.5/10

Diazinon is acaricidal and prednisolone reduces inflammation, but no independent trial supports this product, two treatments 5-7 days apart may not cover the three-week mite life cycle, and ESCCAP favours authorised modern acaricides for cats.

Safety and tolerability3.5/10

Cats are more sensitive to organophosphates than dogs, and grooming adds oral exposure; the label excludes a perforated eardrum, pregnancy, kittens under 4 weeks and combination with other acaricides.

Clinical practicality6.0/10

Two short treatments of 3 drops per ear are easy at home, but both ears and every in-contact animal need treatment.

Full-course cost-effectiveness-

No verified current Georgian price or patient-adjusted course cost was found; foreign prices were not substituted.

Important safety and use flags

  • Do not use with a perforated eardrum, during pregnancy, in kittens under 4 weeks, or together with another acaricide, flea collar or cholinesterase inhibitor.
  • Cats are sensitive to organophosphates: drooling, tremor, small pupils, vomiting or diarrhoea mean poisoning; stop and treat as an emergency (atropine).
  • Prefer an acaricide authorised for cats against ear mites and treat all in-contact animals.
  • Clean the ears first, limit grooming of the ears after dosing, and recheck by otoscopy or microscopy after the course.
  • Use during lactation only for vital indications under veterinary supervision.

    Glucocorticoids, progestogens, and certain endocrinopathies can have an antagonistic effect on insulin activity. Glucocorticoid and progestogen use should be avoided.
