FDA approves NexGard expanded label claims

Merial’s afoxolaner is approved to prevent infections that cause Lyme disease in dogs

Merial, part of Boehringer Ingelheim, received approval from the U.S Food and Drug Administration to expand the label claims for NexGard (afoxolaner). The flea and tick control product is now approved to prevent Borrelia burgdorferi infections as a direct result of it killing Ixodes scapularis vector ticks, commonly called black-legged, or deer, ticks.

NexGard is the first and only flea and tick product to receive FDA approval for preventing infections that cause Lyme disease by killing the vector ticks, the company stated. The approval comes just as veterinarians and pet owners in many parts of the country are being warned about the potential of an increased number of Lyme disease cases in 2018.

The FDA approval is based on two well-controlled laboratory studies that showed that NexGard effectively prevented the transmission of B. burgdorfei infections after dogs were infested with wild-caught I. scapularis ticks 28 days after treatment with NexGard, said the manufacturer.

“Both studies measured the transmission of B. burgdorferi to dogs after exposure to infected ticks,” said Zach Mills, DVM, head of US Pet Veterinary Professional Services. “All dogs treated with NexGard tested negative for B. burgdorferi infection, demonstrating that transmission was prevented as a direct result of NexGard killing the infected ticks. This research shows that NexGard provides a full month of protection against black-legged ticks infected with the bacterium that causes Lyme disease.”

NexGard also kills Lone Star ticks, American dog ticks, and brown dog ticks, and prevents flea infestations by killing adult fleas before they lay eggs.

  1. I was diagnosed a year and a half ago with Lyme disease after three months of flu-like symptoms and severe knee and foot pain. Finally, after several tests and an expensive MRI, I was diagnosed. I was put on doxycycline and had a severe reaction to that, so then they put me on a different medication. My pain still didn’t go away for good. I still had bouts of pain and fatigue that last weeks. I was seeking something to help regain my life to be able to do things for myself. Through my primary physician i learnt about a Lyme disease herbal formula from NATURAL HERBAL GARDENS and their success rate with the treatment, i immediately started on the Lyme disease herbal protocol, I am glad to report the herbal formula worked effectively and there was no side effects, I had a total decline in symptoms, the pains, chronic fatigue and other symptoms stopped, my Lyme disease is totally REVERSED, Here is a link to the website we ordered from ww w.naturalherbalgardens.c om This Herbal Protocol is Incredible!!

  2. I was diagnosed of Lyme disease four years ago. I was so terribly sick. I think my worst complaint was the severe headache. I was taken doxycycline hyclate 100 mg as treatment for Lyme disease, twice a day for 21 days. and didn’t seem to be improving. I did not display a rash or any kind of bull’s eye. Diagnosis was from blood test. We tried every shots available but nothing worked. My Lyme Disease got significantly worse and unbearable because of her cognitive thinking. In 2015, our physician advised we go with natural treatment and was introduced to Organic Herbal Clinic natural organic Lyme Disease Herbal formula, I had a total decline of symptoms with this treatment, the fever, joint pain, weakness, shortness of breath, and anxiety. and others has subsided.
