How Long Does Nexgard Take to Work: A Comprehensive Guide

Nexgard is a widely recommended flea and tick treatment for dogs, but understanding how long it takes to work is crucial for effective pest control. This article provides a detailed exploration of Nexgard's action timeline, including its rapid effectiveness against fleas and its varying response against ticks.

How Nexgard Works

Nexgard is an oral chewable tablet that contains the active ingredient afoxolaner, a highly potent insecticide and acaricide. When ingested, afoxolaner is rapidly absorbed into the bloodstream and distributed throughout the dog's body.

Against Fleas

Nexgard has an impressive speed of action against fleas. Within 4-6 hours of administration, it starts killing fleas on the dog's body. This rapid efficacy effectively breaks the flea life cycle, preventing flea infestations and related skin conditions.

Against Ticks

While Nexgard is highly effective against fleas, its action against ticks is slightly slower. It takes 48 hours for Nexgard to start killing ticks. However, it does not prevent ticks from attaching to the dog. Instead, ticks are killed and detached within 48 hours of attachment, which significantly reduces the risk of tick-borne diseases.

Factors Affecting Action Time

The speed at which Nexgard takes effect can vary slightly depending on several factors:

• Dog's Size and Weight: Larger dogs may take longer for the medication to reach optimal levels in the bloodstream.
• Individual Metabolism: Each dog metabolizes medication differently, which can influence absorption and distribution rates.
• Dosage: Administering the correct dosage is crucial for ensuring maximum efficacy. Check the packaging or consult your veterinarian for the appropriate dosage based on your dog's weight.

Tips and Tricks

• Give Nexgard with food to enhance absorption.
• Administer the chewable tablet whole, as crushing or breaking it may reduce effectiveness.
• Avoid giving Nexgard to dogs under 8 weeks old or weighing less than 4 pounds.
• Keep your dog dry for 24 hours after administration to prevent Nexgard from washing off.

Common Mistakes to Avoid

• Skipping Doses: Regular monthly dosing is essential to maintain Nexgard's effectiveness.
• Giving an Incorrect Dosage: Always use the correct dosage prescribed for your dog's weight.
• Failing to Treat All Dogs in the Household: Ticks can easily spread from one dog to another, so it's vital to treat all dogs in the household with Nexgard.
