What This Medication Is Used For

NexGard Spectra is a prescription chewable tablet for dogs used to treat flea and tick infestations, help prevent heartworm disease, and treat or control certain intestinal roundworms and hookworms.

Conditions it treats
• Fleas and ticks
• Heartworm disease prevention
• Certain intestinal worms, including roundworms and hookworms

Typical symptoms before treatment
• Scratching, chewing, or licking from flea allergy or irritation
• Tick attachment, scabs, or inflamed bite areas
• Ongoing exposure risk based on your region, travel, and outdoor activity

When veterinarians commonly prescribe it
• When your dog needs parasite control that covers both external parasites and specific internal parasites
• When your veterinarian wants one product that fits your dog’s medical history and prevention plan
• When consistent parasite prevention matters for household pets and environmental exposure

How It Works

This product combines two active ingredients that target different parasites. One ingredient addresses fleas and ticks. The other targets heartworm larvae and certain intestinal worms. It does not change your dog’s environment, so your veterinarian may also recommend home and yard steps when fleas are an issue.

How it differs from older or alternative treatments
Some products focus only on fleas and ticks, or only on heartworm and intestinal worms. NexGard Spectra combines coverage in one chewable tablet, if your veterinarian decides it is appropriate.

Why vets use it for ongoing management
Parasite control often needs a plan that matches where you live, how your dog spends time outdoors, and your dog’s health status. Your veterinarian can adjust the approach over time based on risk and testing history.

Dosage and Strength Information

Dosage and timing are set by your veterinarian. Do not change the plan on your own.

What this specific strength is generally prescribed for
The Medium (green) strength, 7.5 mg/37.5 mg, is commonly selected when your veterinarian wants a tablet strength that fits a mid-size dog’s prevention plan and helps keep dosing practical.

Other NexGard Spectra strengths:
NexGard Spectra XS (orange)
NexGard Spectra Small (yellow)
NexGard Spectra Large (purple)
NexGard Spectra XL (red)
