Nexgard Without a Prescription – Supplied Under Australian Regulations
Many U.S. pet owners search for Nexgard without a prescription. The reason this is possible through our store comes down to international regulatory differences.

We ship directly to customers in the United States and the United Kingdom for personal use. Import rules may vary, so customers are responsible for ensuring compliance with their local regulations.
Our goal is to offer convenient access to authentic parasite protection while maintaining transparency about how and why these products are available without a prescription through our Australian supply channel. For medical advice or suitability questions, we always recommend consulting your veterinarian.

Frequently Asked Questions About NexGard
- How does NexGard achieve results?
The active ingredient, afoxolaner, enters the bloodstream; when parasites bite, they ingest the medication and are quickly neutralized. - How fast will NexGard start working?
You’ll see it start killing fleas within 4 hours, and it typically clears a full infestation within 24 hours. - How long does a single dose of NexGard last?
It is designed to provide consistent protection for a full 30 days. - Why do vets prefer NexGard over topical oils?
Being an oral chew, there’s no sticky residue on the fur, so you can bathe your dog or let them swim immediately after treatment.
- Which specific ticks does NexGard cover?
It targets the most dangerous ones, including Deer ticks (which carry Lyme), American Dog ticks, Lone Star ticks, and Brown Dog ticks. - Does NexGard protect against heartworm?
No. NexGard is strictly for external parasites. You will need a separate preventative for heartworm and intestinal worms. - Can NexGard help with Lyme disease?
Yes, by killing Deer ticks rapidly, the medication reduces the risk of the tick transmitting Lyme bacteria to your dog. - Why am I still seeing fleas after giving NexGard?
This is normal during the early stages of treatment. Only about 5% of fleas live on your dog—the rest are in the environment (eggs, larvae, pupae). Fleas may continue to emerge for several weeks until the life cycle is broken. - Is NexGard effective against mange?
While not its primary label use, we often prescribe it to treat Sarcoptic or Demodectic mange with great success.
- Is NexGard safe for long-term use?
Yes, it is FDA-approved and has a very high safety profile for most healthy dogs. - What are the typical side effects of NexGard?
While uncommon, some dogs may experience mild vomiting, diarrhea, or a temporary loss of appetite. - What is the concern with seizures and NexGard?
As with other isoxazolines, rare neurological side effects have been reported. Dogs with a history of seizures or epilepsy should be monitored closely. - What should I do if my dog reacts to NexGard?
If your dog shows any adverse reactions, contact a veterinarian immediately. - Can NexGard be used with heartworm prevention products?
Yes. NexGard is commonly used alongside heartworm preventatives such as Heartgard Plus to provide broader parasite protection.
- At what age can my puppy start NexGard?

Contact a vet immediately. NexGard is formulated specifically for dogs and is not intended for cats. - Is there beef in NexGard for dogs with allergies?
The beef flavoring is soy-based, so many dogs with beef-protein allergies can still take it safely.
