Comfort

diazinon 60 mg/g collar, 32.5 ± 2.5 cm for cats
Assessed clinical scopeCat · Full cat label from 8 weeks: flea and tick protection for up to 4 months with a diazinon 60 mg/g organophosphate collar · On the skin
Care settingNot recommended for cats; use a cat-authorised product from a safer class
vetman score 3.9/10 Poor / unconvincing
Evidence confidence: Low Georgia: Yes, veterinary · № 000450 · Verified on 21 Oct 2026

A poor option for cats: an organophosphate collar in the species most sensitive to organophosphate poisoning, with no efficacy data. Choose a cat-authorised spot-on or collar from a safer class.

Regulatory and scientific credibility4.0/10

The collar is registered in Georgia (000450, valid to 2028) with a current Ukrainian manufacturer instruction, but no EU, UK or US authorisation was documented in the reviewed evidence or public dossier.

Clinical efficacy4.0/10

No independent study supports this collar's 4-month flea and tick claim in cats.

Safety and tolerability2.5/10

Cats are especially sensitive to organophosphates; continuous neck contact, grooming and chewing make cholinergic poisoning a real risk, and no breakaway release is described.

Clinical practicality6.0/10

One collar for 4 months is easy to fit.

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

  • Organophosphate in a cat: remove the collar and seek urgent care for salivation, vomiting, miosis, tremor, weakness or seizures; atropine is the antidote.
  • Do not combine with other organophosphates, carbamates or cholinesterase-inhibiting drugs.
  • Do not use in kittens under 8 weeks, sick, debilitated or old cats, or during pregnancy or lactation.
  • No breakaway release is described; check the fit and keep the collar away from children and other pets.
  • Wash hands with soap and water after handling.

diazinon 60 mg/g collar, 65 ± 5 cm for dogs
Assessed clinical scopeDog · Full dog label from 8 weeks: flea and tick protection for up to 4 months with a diazinon 60 mg/g organophosphate collar · On the skin
Care settingOwner-fitted collar on a healthy adult dog in a home without cats or small children, only where safer classes are unavailable
vetman score 4.5/10 Weak evidence support
Evidence confidence: Low Georgia: Yes, veterinary · № 000425 · Verified on 21 Oct 2026

A weak option: an easy collar, but an organophosphate with poisoning risk and no product evidence. Collars or tablets from newer classes are safer and better supported.

Regulatory and scientific credibility4.0/10

The collar is registered in Georgia (000425, valid to 2028) with a current Ukrainian manufacturer instruction, but no EU, UK or US authorisation was documented in the reviewed evidence or public dossier.

Clinical efficacy4.0/10

Organophosphate collars have historical activity against fleas and ticks, but no independent study supports this collar's 4-month claim, and current guidelines rely on newer classes.

Safety and tolerability4.5/10

Diazinon inhibits cholinesterase; chewing the collar or combining it with other cholinesterase inhibitors can cause salivation, vomiting, tremor and seizures, and the label excludes young, sick, old, pregnant and lactating dogs.

Clinical practicality6.0/10

One collar fitted with a 1-1.5 cm gap is simple to use for 4 months.

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 combine with other organophosphates, carbamates (such as propoxur) or cholinesterase-inhibiting drugs; atropine is the antidote.
  • If the collar is chewed or swallowed by the dog, another pet or a child, remove it and seek urgent care for salivation, vomiting, miosis, tremor or seizures.
  • Do not use in puppies under 8 weeks, sick, debilitated or old dogs, during pregnancy or lactation, or with diazinon hypersensitivity.
  • Stop use if hair loss, itching or skin irritation appears under the collar.
  • Wash hands with soap and water after handling.
