Boehringer Ingelheim Nexgard Spectra Tick & Flea 3 Chewable Tablet For Dogs >15 - 30kg

Boehringer Ingelheim NexGard Spectra for Dogs (15 to 30 kg) - One Monthly Chew for Fleas, Ticks, Worms, and Heartworm

Most parasite prevention routines involve at least two products - a flea and tick treatment and a separate dewormer, given on different schedules, remembered separately. The NexGard Spectra changes that entirely.

One soft, beef-flavoured chewable tablet. Given once a month. Covers fleas, ticks, mites, roundworms, hookworms, whipworms, heartworm, lungworm, and eyeworm - all in a single dose. For pet parents who want genuinely comprehensive parasite protection without juggling multiple products and schedules, NexGard Spectra is one of the most complete monthly parasite control options available in India today.

Manufactured by Boehringer Ingelheim, São Paulo, Brazil - and marketed in India by Boehringer Ingelheim India Pvt. Ltd., Mumbai. Approved by the CDSCO.

Each tablet for the 15-30 kg range contains: Afoxolaner - 75 mg and Milbemycin Oxime - 15 mg.

Pack: 3 tablets - one box covers 3 months of protection. Price: ₹3,375.

This is a prescription medication. Use only under veterinary supervision.

What Are the Uses and Benefits of NexGard Spectra for Dogs (15-30 kg)?

NexGard Spectra is the only monthly oral chew in India that covers both external and internal parasites in a single dose. Here's the full picture of what it protects against:

• Fleas are killed within 4 hours of the chew being given - before they can lay eggs. Over 99% effectiveness is observed at 8 hours. By eliminating fleas this quickly, NexGard Spectra also eliminates the flea life cycle, preventing the eggs and larvae from ever establishing. For dogs with Flea Allergy Dermatitis - itchy, inflamed skin triggered by flea saliva - faster flea kill means less of the allergic response driving the misery. The blog on how to spot and treat skin infections in dogs covers flea-related skin issues in detail.
• Ticks - including the Brown Dog Tick (Rhipicephalus sanguineus), the dominant tick species in Indian cities, as well as Ixodes, Dermacentor, and Haemaphysalis species - are killed within hours of biting. For dogs in India's urban and semi-urban environments, tick-borne diseases like Ehrlichiosis and Babesiosis are a genuine, recurring threat. For more on what tick fever looks like and how serious it can be, the blog on tick fever in dogs - symptoms, treatment and prevention is essential reading.
• Mites - both Demodex canis (causing Demodectic mange) and Sarcoptes scabiei (causing Sarcoptic mange / scabies) - are treated by NexGard Spectra. Over 97.5% reduction against Demodex mites after just three monthly treatments, and 99% effectiveness against Sarcoptes mites with a single dose, have been demonstrated in clinical studies.
• Heartworm (Dirofilaria immitis) larvae are 100% eliminated with monthly use. India's mosquito-heavy climate makes heartworm transmission a real risk for dogs in many parts of the country - particularly those who spend time outdoors. Left untreated, heartworm causes progressive, life-threatening heart and lung disease. NexGard Spectra prevents heartworm disease entirely when given consistently.
• Roundworms (Toxocara canis, Toxascaris leonina) - more than 95% efficacy in clinical studies. Hookworms (Ancylostoma caninum, Uncinaria stenocephala) - more than 90% efficacy. Whipworms (Trichuris vulpis) - more than 98.3% efficacy. All three of the most common intestinal worms in Indian dogs cleared by a single monthly chew.
• Lungworm (Angiostrongylus vasorum) and Eyeworm (Thelazia callipaeda) are also covered with full efficacy when NexGard Spectra is given monthly - two lesser-known but genuinely present parasite threats in Indian dogs.
• For pet parents currently giving a separate dewormer alongside a monthly flea and tick product, NexGard Spectra consolidates everything into one chew - one product, one schedule, nothing to forget separately. For more on intestinal worm warning signs, the blog on dog worms - warning symptoms and prevention is a helpful reference.

What Are the Possible Side Effects?

• NexGard Spectra is well-tolerated by the vast majority of dogs. Most complete the monthly routine without any issues at all.
• Mild and temporary digestive effects - vomiting, loose stools, or reduced appetite - occasionally occur after administration. Giving with food significantly reduces this.
• Brief lethargy in the 24 hours after administration has been reported in some dogs. This passes without intervention.
• In dogs with a history of seizures or neurological disorders, afoxolaner - like all isoxazoline-class products - should be used with caution. If your dog has ever had a seizure, inform your vet before starting NexGard Spectra. Neurological adverse events including tremors and seizures have been reported in rare cases in predisposed dogs.
• Allergic reactions are possible but rare. Facial swelling, breathing difficulty, or sudden severe deterioration after administration warrants immediate veterinary contact.

How Should You Give NexGard Spectra to Your Dog?

• NexGard Spectra is given as a single soft chew once every 30 days. It should be given with food or immediately after a meal - this improves absorption of both active ingredients and reduces the chance of digestive upset.
• Most dogs in this weight range accept the beef-flavoured chew enthusiastically as a treat. If your dog is reluctant, offer it alongside or wrapped in a small amount of food they enjoy. Watch for a minute or two after giving it to confirm it's been fully chewed and swallowed.
• One tablet covers dogs between 15 kg and 20 kg. For dogs between 20 kg and 30 kg, confirm the correct dose with your vet - the 15-30 kg range spans a wide weight band, and your vet will confirm this variant is appropriate for your dog's specific weight.
• Weigh your dog before each monthly dose - particularly dogs at the weight boundaries. A dog who gains or loses weight to fall outside this range will need a different variant.
• Each box contains 3 tablets, providing 3 months of complete protection.
• Safe from 8 weeks of age and 2 kg body weight. The 15-30 kg variant is specifically calibrated for dogs in this weight range - always use the variant matched to your dog's actual weight.

How Does NexGard Spectra Work?

• NexGard Spectra works through two active ingredients with completely different targets - one handling external parasites, the other handling internal ones.
• Afoxolaner is an isoxazoline-class ectoparasiticide. After being absorbed through the gut and entering the bloodstream, it is distributed throughout the body and reaches parasite feeding sites. When a flea or tick bites your dog and ingests blood, it also ingests afoxolaner. Afoxolaner then blocks GABA-gated and glutamate-gated chloride ion channels in the parasite's nervous system - these channels regulate nerve signals, and blocking them causes uncontrolled nerve firing, paralysis, and rapid death. Because it works systemically through the blood rather than sitting on the coat, it cannot be washed off and works consistently regardless of bathing or coat thickness. Fleas are killed within 4 hours; ticks within hours of feeding.
• Milbemycin Oxime handles the internal parasites. It's a macrocyclic lactone - the same class of drug used in many trusted dewormers globally. It works by increasing the permeability of chloride ion channels in the nerve and muscle cells of roundworms, hookworms, whipworms, and heartworm larvae - causing paralysis and death. At monthly doses, it prevents heartworm larvae from progressing to the dangerous adult stage. It also drives efficacy against mange mites when used regularly.
• The two ingredients work independently through different mechanisms against their respective targets - which is what makes the combination genuinely broad-spectrum. There is no single antiparasitic product in India that covers this range of parasites as comprehensively in one monthly oral dose.
