Why Veterinarians Recommend Credelio as the Top Flea Treatment for Cats
When it comes to safeguarding your feline friend from fleas and ticks, veterinarians often recommend Credelio for cats. This prescription flea treatment contains lotilaner, an active ingredient from the isoxazoline class, designed to provide fast-acting, long-lasting protection against parasites. Approved by the FDA, Credelio offers a convenient monthly oral solution, making parasite prevention simple and effective for pet owners.
What Is Credelio?
Credelio is a small, flavored chewable tablet given once a month to cats and kittens. It begins killing adult fleas within six hours and eliminates more than 98% of them in 12 hours. The full effect is typically reached within 24 hours. It also provides effective control of black-legged ticks (Ixodes scapularis), offering over 97% protection sustained for up to 31 days.
Who Can Use Credelio?
- Cats and kittens 8 weeks or older, weighing at least 2 pounds—for flea control
- For tick control, it is approved for cats aged 6 months or older
- Not recommended for breeding, pregnant, or lactating cats
- Use caution in cats with neurological disorders
How Does It Work?
The active ingredient lotilaner disrupts parasite nervous systems by targeting GABA-gated chloride channels. This causes paralysis and death in fleas and ticks without affecting your cat. Its selectivity stems from the significant differences between parasite and mammalian GABA receptors, contributing to its high safety profile.

Rare but serious neurologic side effects such as tremors or seizures have been reported. Cats with a known history of seizures should use Credelio with caution and always under veterinary supervision. Most side effects are mild and resolve quickly once the drug is discontinued.
What to Do if You Miss a Dose
If a dose is missed, administer the pill with food as soon as possible and resume regular monthly dosing from that date. Do not double up on doses.

Can It Be Used With Other Medications?
Credelio generally shows no significant drug interactions when used with:

Why Monthly Treatment Matters
Consistent monthly application is essential. Regular use not only kills existing fleas but also prevents re-infestation by eliminating eggs and larvae. You can begin treatment any time of year, but experts recommend year-round protection to ensure your cat remains parasite-free.
