Why Flea & Tick Prevention Matters
Fleas and ticks are more than a nuisance — they carry diseases that can seriously harm your pet. Fleas cause intense itching, allergic reactions (flea allergy dermatitis), and can transmit tapeworms. Ticks carry Lyme disease, ehrlichiosis, anaplasmosis, and Rocky Mountain spotted fever.
Year-round prevention is the standard of care recommended by veterinarians. Prescription-strength preventatives are more effective than over-the-counter products and protect against a wider range of parasites.
Prescription vs Over-the-Counter
| Factor | Prescription (Vet-Prescribed) | Over-the-Counter |
|---|---|---|
| Effectiveness | 95-100% kill rate within 24 hours | Variable, often 70-85% |
| Duration | 1-3 months per dose | Requires frequent reapplication |
| Parasites covered | Fleas, ticks, heartworm, intestinal worms | Usually fleas only |
| Safety profile | Vet-matched to your pet's weight and health | One-size-fits-all, risk of misuse |
| Application | Oral chew (easy) or topical | Mostly topical (messy) |
| Vet oversight | Prescribed with dosage guidance | No professional guidance |

Flea & Tick Prevention FAQs
Can an online vet prescribe flea and tick prevention?
Yes. Licensed veterinarians can prescribe prescription-strength flea and tick preventatives like Simparica Trio, NexGard, Bravecto, and others during a video consultation in Florida, New York, and Virginia.
Do I need a prescription for flea medication?
The most effective flea and tick products (like Simparica Trio, NexGard, and Bravecto) require a veterinary prescription. Over-the-counter products exist but are less effective and protect against fewer parasites.
How often should my pet get flea and tick prevention?
Most vets recommend year-round monthly prevention. Some products like Bravecto last 3 months per dose. Your vet will recommend the right schedule based on your pet's risk factors and location.
My indoor cat — does it need flea prevention?
Yes. Indoor cats can still get fleas from other pets, visitors, or fleas that enter on clothing and shoes. Indoor cats are also less likely to have built up any resistance, making infestations worse when they occur.
What's the difference between prescription and store-bought flea medication?
Prescription products typically kill 95-100% of fleas and ticks within 24 hours and protect against more parasites (including heartworm in some products). Store-bought products often have lower efficacy and cover only fleas.
