Introduction: What is Nexgard?
Nexgard is a chewable flea and tick medication for dogs that was first introduced in 2013. It is manufactured by Merial, a company that has been producing veterinary products for over 50 years. Nexgard is available only by prescription and contains a single active ingredient called afoxolaner.
Active Ingredient: Afoxolaner
Afoxolaner is a member of the isoxazoline class of drugs that works by inhibiting the nervous system of fleas and ticks. When a flea or tick bites a dog that has taken Nexgard, it ingests the afoxolaner and becomes paralyzed. This prevents the flea or tick from feeding and ultimately leads to its death.
How does Nexgard work?
Nexgard is a fast-acting flea and tick medication that starts working within hours of administration. It is designed to kill fleas and ticks for up to 30 days, providing continuous protection against these pests. Nexgard is also effective against a variety of tick species, including the American dog tick, the lone star tick, and the black-legged tick, which is known to transmit Lyme disease.
Why is Nexgard prescribed?
Nexgard is prescribed to dogs that are at risk of flea and tick infestation. This includes dogs that spend time outdoors or live in areas with high flea and tick populations. Nexgard is also recommended for dogs that have a history of flea or tick infestations or have been diagnosed with flea or tick-borne illnesses.
Can dogs safely take Nexgard?
Yes, dogs can safely take Nexgard when it is administered according to the prescribed dosage. Nexgard has been extensively tested for safety and efficacy and has been approved by the FDA for use in dogs. However, it is important to note that Nexgard is a prescription medication and should only be used under the supervision of a veterinarian.
Possible side effects of Nexgard
Like all medications, Nexgard can cause side effects in some dogs. The most common side effects of Nexgard include vomiting, diarrhea, and lethargy. In rare cases, dogs may experience more serious side effects, such as seizures or allergic reactions. If your dog experiences any unusual symptoms after taking Nexgard, contact your veterinarian immediately.
Precautions and Warnings
Nexgard should not be given to dogs that are under 8 weeks of age or weigh less than 4 pounds. It is important to use caution when administering Nexgard to dogs with a history of seizures or neurological disorders, as afoxolaner may lower the seizure threshold. Additionally, Nexgard should not be used in dogs that are pregnant or lactating.
