What This Medication Is Used For
NexGard (afoxolaner) is a prescription parasite control medication for dogs. Veterinarians use it to treat and control flea infestations certain tick infestations and treat mange caused by Demodex canis
Conditions it treats:
• Flea infestations
• Tick infestations (species vary by region)
• Demodicosis caused by Demodex canis, when a veterinarian decides it is appropriate
Typical symptoms before treatment:
• Persistent scratching, biting, or licking
• Flea dirt or visible fleas in the coat
• Ticks found attached after time outdoors
• Patchy hair loss, redness, or scaling in cases your veterinarian suspects mites
When veterinarians commonly prescribe it:
• When your dog needs an oral option for flea and tick control
• When parasites are a recurring issue in your home or in places your dog visits
• When your veterinarian is managing skin irritation linked to flea bites as part of a broader plan
How It Works
NexGard works systemically. After your dog takes the chewable tablet, the active ingredient circulates in the body. Fleas and ticks must attach and feed to be exposed to the medication.
NexGard contains afoxolaner, which affects nerve signalling in fleas and ticks. That action kills the parasites after they feed.
How it differs from older or alternative treatments:
• Some products are applied to the skin or worn as a collar
• NexGard is given by mouth as a chewable tablet
Your veterinarian will recommend an approach based on your pet’s history, exposure risk, and other medications.
Why vets use it for ongoing management:
Parasite control often works best as a consistent plan during higher-risk seasons. Your veterinarian may include NexGard as part of that plan and adjust it over time based on weight changes and local tick activity.
