Specially designed for medium-sized dogs weighing between 10 and 25 kilograms, NexGard Spectra combines ease of use with unmatched effectiveness.

What is NexGard Spectra 10–25kg for Dogs?

NexGard Spectra is a monthly chewable tablet manufactured by Boehringer Ingelheim, designed for medium-sized dogs (10–25kg). It offers broad-spectrum parasite control, including:

It is palatable, easy-to-administer, and acts rapidly—offering pet owners peace of mind with one simple monthly chew.

Active Ingredients and Their Roles

Active Ingredient

Concentration Function
Afoxolaner 75.0 mg

Kills adult fleas and ticks by overstimulating their nervous system

Afoxolaner

  • Interferes with GABA- and glutamate-gated chloride channels in parasites.

Milbemycin Oxime

  • Belongs to the milbemycin class of macrocyclic lactones.
  • Disrupts neurotransmission in parasites.
  • Protects against heartworms and treats intestinal worms.

Indications for Use

1. Flea Infestations (Ctenocephalides spp.)

  • Rapidly kills adult fleas.
  • Effective for monthly flea control.
  • Aids in controlling flea allergy dermatitis (FAD).

2. Tick Infestations

  • Controls Ixodes, Dermacentor, Rhipicephalus, and Haemaphysalis
  • Prevents tick-borne diseases like Ehrlichiosis, Babesiosis, and Lyme disease.

3. Heartworm Disease (Dirofilaria immitis)

  • Prevents heartworm larval development.
  • Monthly dosing ensures continuous protection.

4. Intestinal Worms

  • Treats and controls:
    • Roundworms (Toxocara canis, Toxascaris leonina)
    • Hookworms (Ancylostoma caninum, Uncinaria stenocephala)
    • Whipworms (Trichuris vulpis)

5. Mange and Mite Infestations (Off-label use)

Dosage Guidelines and Administration of NexGard Spectra 10–25kg for Dogs

Correct dosage and administration are critical for ensuring maximum efficacy and safe use of NexGard Spectra 10–25kg for Dogs. This section outlines the proper way to dose, administer, and handle the product based on your dog’s body weight.

Product Overview

  • Form: Chewable tablet
  • Strength:
    • Afoxolaner: 75 mg
    • Milbemycin Oxime: 15 mg
  • Target weight range: 1 kg to 25 kg
  • Frequency: Once every 30 days (monthly)

Dosage for NexGard Spectra

Dog Body Weight

NexGard Spectra Variant Tablet Strength Tablets per Dose Administration Frequency
10.1 – 25.0 kg 10–25 kg (Medium Dogs) 75/15 mg 1 chewable Once every month (30 days)
>25 kg Use next higher strength Follow label See vet advice Once monthly
<10 kg Use lower strength variant Follow label See vet advice

Once monthly

Important: Do not split or share tablets between dogs. Each tablet is formulated for a specific weight class.

How to Administer

  • Step 1: Remove the chewable from the blister pack.
  • Step 2: Offer directly by hand or hide in food.
  • Step 3: Ensure your dog chews completely before swallowing.
  • Step 4: Observe your dog for a few minutes to confirm full ingestion.

Administration Tips

  • Can be given with or without food.
  • Most dogs readily accept the chewable due to its palatable beef-flavor.
  • If your dog does not voluntarily chew, you may place the tablet directly in the mouth near the back of the tongue.
  • Ensure no tablet pieces are spit out or left behind.

How NexGard Spectra Works: Scientific Overview

Mode of Action

  • Afoxolaner: Targets the nervous system of fleas and ticks by binding to chloride channels. Causes overexcitation → paralysis → death.
  • Milbemycin Oxime: Binds to glutamate-gated chloride ion channels in parasites → hyperpolarization of neurons → parasite death.

Onset of Action

  • Kills fleas within 6 hours post-administration.
  • Kills ticks within 8–12 hours.
  • Prevents reinfestation for a full month.

Safety and Precautions

While NexGard Spectra 10–25kg for Dogs is generally safe and well-tolerated, understanding the safety considerations and precautions is crucial for ensuring your dog’s well-being. Below is a detailed breakdown of the key safety information:

General Safety Profile

  • Extensively tested in clinical trials for safety, including in sensitive breeds such as collies.
  • Well-tolerated even when administered with other common veterinary medications like vaccines, antibiotics, NSAIDs, and anesthetics.
  • Designed specifically for dogs—do not use in cats or other species.

Use with Caution In:

Condition

Precaution
Dogs with seizure history Although rare, NexGard Spectra may trigger neurological reactions in predisposed dogs. Consult your vet.
Breeding, pregnant, or lactating females Safety has not been fully established. Use only if clearly necessary and directed by a vet.
Debilitated or underweight dogs Extra caution required—closely monitor for side effects.
Dogs with known hypersensitivity to active ingredients

Avoid use.

Do Not Use In:

  • Cats – Afoxolaner is toxic to felines.
  • Dogs under 2 kg body weight or under 8 weeks of age.
  • Dogs with known allergic reactions to Afoxolaner or Milbemycin Oxime.

Precautions for Use

  1. Accurate Weight Measurement
    • Ensure your dog’s body weight falls within the 10–25kg range.
    • Use the correct chewable strength for optimal safety and efficacy.
  2. Do Not Split Tablets
    • Splitting can lead to under- or overdosing.
  3. Keep Out of Reach of Children
    • Store in original blister packs in a cool, dry place (<30°C).
    • Do not leave tablets unattended on counters or floors.
  4. Watch for Side Effects
    • Monitor your dog for 24 hours after administration, especially if it’s the first dose.
    • Common side effects (usually mild and self-limiting): vomiting, diarrhea, lethargy, itching.
  5. Accidental Ingestion by Other Pets or Humans
    • Seek immediate medical or veterinary attention if other animals or children ingest the chewable.
  6. Environmental Control Still Needed
    • NexGard Spectra kills adult fleas and prevents infestations, but does not kill flea eggs or larvae in the environment.
    • Regularly clean bedding, vacuum carpets, and treat the environment if needed.

Drug Interactions

No significant drug interactions have been reported. However:

  • Always inform your veterinarian of any medications or supplements your dog is currently taking.

Aftercare and Monitoring

  • Keep a monthly treatment schedule using a calendar or pet care app to avoid missed doses.
  • If a dose is missed and a significant time has passed, consult your vet about heartworm testing before resuming.

Veterinarian Advice

“While NexGard Spectra is among the safest oral parasiticides available, it’s important to dose correctly and keep a close eye after the first administration. Always read the label and consult your vet for dogs with health issues or medication regimens.” — Dr. Anjali Menon, DVM

Side Effects and Adverse Reactions

Side Effect Severity Action
Vomiting Mild Usually self-limiting
Diarrhea Mild Monitor and hydrate
Lethargy Mild Observe, usually resolves in 24 hrs
Skin reactions Rare Discontinue and consult vet if persistent
Seizures Very rare Higher risk in dogs with seizure history

Note: Always consult your veterinarian before starting any parasiticides, especially if your dog has a history of seizures or neurological conditions.
