Boehringer Ingelheim Nexgard Spectra Tick & Flea Tablet (15 to 30kg) for Dogs (Afoxolaner & Milbemycin Oxime)

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.

What Safety Advice Should You Know Before Using NexGard Spectra?

• This product is for dogs only. Do not use on cats.
• Do not use on puppies under 8 weeks of age or weighing less than 2 kg.
• Do not use on dogs with a known history of seizures or neurological disorders without explicit vet guidance. The isoxazoline component (afoxolaner) has been associated with neurological adverse events in predisposed dogs - your vet must assess the risk-benefit for your specific dog.
• Do not use on sick, severely debilitated, or significantly underweight dogs without vet clearance.
• Use with caution in senior dogs and dogs with known liver or kidney disease. Both afoxolaner and milbemycin oxime are processed by the liver - dogs with impaired liver function may clear the drug differently, and your vet will assess the appropriate approach.
• Always give with food. Never give on a completely empty stomach.
• If your dog has never been on heartworm prevention and lives in a heartworm-risk area, your vet may recommend a heartworm test before starting NexGard Spectra. The product prevents heartworm disease in uninfected dogs but is not a treatment for existing adult heartworm infections.
• Do not combine with other antiparasitic products or macrocyclic lactone-containing medications without explicit vet guidance.
• Safe for use in pregnant and lactating females based on available safety data. Confirm with your vet before use during pregnancy.
• Store below 30°C away from direct sunlight in the original packaging. Keep out of reach of children. Wash hands after handling.

What Should You Do If You Miss a Dose?

• Give the tablet as soon as you remember and reset your monthly schedule from that new date. Do not give two tablets at once.
• For heartworm prevention, consistency is especially important - gaps in monthly protection allow larvae to progress beyond the stage at which they can be eliminated. If you've missed more than a month in a heartworm-risk area, speak to your vet before resuming.
• During any gap in coverage, check your dog's coat manually after outdoor walks and monitor for signs of flea or tick activity. Resume NexGard Spectra as soon as possible.
• Set a recurring monthly phone reminder the moment you give each dose. With a product this comprehensive, consistency is everything.

What Are All the Substitutes for NexGard Spectra for Dogs (15-30 kg)?

If NexGard Spectra is unavailable or your vet recommends a different approach, here are other parasite protection options for dogs in this weight range on Supertails. Note that no single alternative covers the same breadth of parasites in one monthly dose - most alternatives will require two separate products:

What Are Some Quick Tips for Getting the Most Out of NexGard Spectra?

• Always give with a full meal. Both afoxolaner and milbemycin oxime are better absorbed with food - this isn't optional advice, it meaningfully affects how well the product works. A full meal, not just a small treat, gives the best results.
• Mark the date of each dose and set a 30-day reminder immediately. Monthly consistency is more important here than with quarterly products - particularly for heartworm prevention, where gaps allow larvae to progress.
• Weigh your dog before each monthly dose. Dogs at the boundary of weight ranges should be checked every few months - weight changes can mean they need a different variant.
• If you're transitioning to NexGard Spectra from separate products - say, a spot-on plus a dewormer - ask your vet about the right timing to switch. If your spot-on's protection window hasn't expired yet, your vet will advise when to start the first NexGard Spectra dose to avoid any gap or overlap.
• Continue manual post-walk tick checks even while your dog is on NexGard Spectra. The product kills ticks within hours of attachment - but checking after every walk in tick-heavy areas is a good habit that lets you catch and remove any ticks before they feed. The blog on how to identify and remove ticks from your dog shows the right removal technique.

FAQs

What is NexGard Spectra used for in dogs?

NexGard Spectra is a broad-spectrum monthly oral chewable that combines two active ingredients - Afoxolaner and Milbemycin Oxime - to cover both external and internal parasites in a single dose. It treats and prevents fleas, ticks, Demodectic and Sarcoptic mange mites, roundworms, hookworms, whipworms, heartworm, lungworm, and eyeworm. It is the only monthly oral product in India approved to cover all these parasites together.

How is NexGard Spectra different from regular NexGard?

Regular NexGard contains only Afoxolaner - it covers fleas and ticks. NexGard Spectra adds Milbemycin Oxime, which extends coverage to intestinal worms, heartworm prevention, lungworm, and eyeworm. Think of NexGard Spectra as NexGard plus a monthly dewormer, combined into a single chew - one product handling everything that would previously require two separate products on two different schedules.

Does NexGard Spectra replace my dog's separate dewormer?

For most dogs, yes - NexGard Spectra covers roundworms, hookworms, and whipworms with the same monthly dose that handles fleas and ticks. However, it does not contain praziquantel and therefore does not treat tapeworms. If your dog has a confirmed tapeworm infestation - recognisable as rice-grain-like segments near the rear end or in the stool - a separate praziquantel-containing treatment may still be needed. Confirm with your vet whether NexGard Spectra fully replaces your current deworming routine or needs to be supplemented for tapeworm coverage.

My dog has had seizures. Can I give NexGard Spectra?

Discuss this explicitly with your vet before using NexGard Spectra. Afoxolaner is an isoxazoline-class drug, and neurological adverse events including tremors and seizures have been reported in rare cases in dogs with pre-existing seizure disorders or neurological conditions. This doesn't automatically exclude your dog from using the product, but your vet must assess the risk-benefit balance for your specific dog's history and severity before prescribing.

Can NexGard Spectra prevent heartworm disease?

Yes - when given consistently every month, NexGard Spectra eliminates heartworm larvae (L3 and L4 stages) before they can mature into adults, providing 100% heartworm prevention in clinical studies. It does not treat existing adult heartworm infections. If your dog has never been on heartworm prevention before, your vet may recommend testing for existing heartworm infection before starting monthly NexGard Spectra - particularly if you live in a high-mosquito-exposure area.

How quickly does NexGard Spectra kill fleas?

Fleas begin dying within 4 hours of NexGard Spectra being given. Over 99% of fleas are dead at the 8-hour mark. This speed is meaningful for dogs with Flea Allergy Dermatitis - the faster fleas are eliminated, the fewer bites trigger the allergic reaction driving the itching and skin inflammation.

Is NexGard Spectra safe for pregnant dogs?

NexGard Spectra is considered safe for use in pregnant and lactating females based on available safety data. That said, always inform your vet before giving any pharmaceutical product to a pregnant or nursing dog, so they have a complete picture of your dog's management during this period and can confirm the timing is appropriate.

One box has 3 tablets. Does that mean I only need to buy it 4 times a year?

Each box of 3 tablets covers 3 months of monthly protection. For full year-round coverage, you'll need approximately 4 boxes per year (12 tablets total). At ₹3,375 per box, this works out to about ₹13,500 per year for complete, monthly broad-spectrum parasite protection - covering fleas, ticks, worms, and heartworm in a single monthly chew, replacing multiple separate products.
