Each 57mg tablet contains nitenpyram, which kills fleas within 15 minutes and achieves over 95% eradication in 6 hours, with full clearance by 24 hours. The residue-free formula is safe to use alongside other flea and worm treatments, including spot-ons and collars, making it an essential, mess-free solution for immediate flea relief and integration into year-round pest control. ## Description From the manufacturer 4fleas Tablets for Large Dogs How it Works Johnson’s 4Fleas Tablets use nitenpyram , a fast-acting oral treatment for fleas. After dosing, it’s absorbed into the bloodstream; any flea that bites ingests the active and its nervous system is rapidly over-stimulated, leading to paralysis and death. Fleas start to die within 15 minutes, with more than 95% gone in six hours and complete eradication by 24 hours. Because the drug clears quickly, there’s no residue on coat or in the home, and it can be used alongside spot-ons or IGR sprays as part of a full flea-control programme. How to Use Johnson’s 4fleas tablets can be given directly into the mouth or may be mixed in a small portion of your pet’s favourite food and given immediately. Administer one treatment on any day when fleas are seen on your pet. Repeat on any subsequent day as necessary. Do not give more than one treatment per day. Between 11.1kg (24.4lbs) and 57kg (125.4lbs) - 1 tablet whenever you see fleas on your pet Above 57kg (125.4lbs) - 2 tablets whenever you see fleas on your pet Key Features Rapid Action: Kills fleas in 15 minutes; full kill within 24 hours. Oral Dose: No mess, no coat residue Combined Usage: Safe with spot-ons, collars, and home treatments Wide Suitability: From 11kg; for safe use in pregnant/lactating females & breeding dogs Veterinary Strength and Quality: Ideal for rapid knockdown in heavy infestations. Effective With One Dose: One or two tablets (depending on weight), repeat after 24 hours as needed. Johnson’s 4Fleas Tablets for Large provide the quickest route to relief when fleas strike. Each small, easy-to-dose tablet contains nitenpyram, a veterinary-active molecule renowned for its speed: once swallowed, it is absorbed rapidly, and any flea that bites your dog ingests the active ingredient. Within minutes, fleas become hyperactive, stop feeding and begin to die; by six hours you’ll see the vast majority gone, and within 24 hours the infestation on your pet is effectively cleared. Unlike many topical preparations, 4Fleas Tablets leave no sticky residue, odour, or staining . There’s nothing to rub off on furniture, children, or other pets, making it a particularly convenient option for households where tactile contact with pets is constant. Because the active clears from the body within a day, you’re providing a sharp, targeted strike against existing fleas without committing your dog to a long-acting systemic treatment. That also means you can use the tablets alongside other topical products without concern, such as monthly spot-ons, collars, environmental sprays or foggers which may all be layered in to provide lasting protection and to break the flea life cycle in the home. Dosing is intentionally simple: one tablet treats any dog or puppy between 11kg and 57kg, two tablets for those over 57kg. Puppies must be at least four weeks old, but beyond that there are no contraindications: the product can be used in pregnant or lactating queens and in breeding dogs. Administration is flexible: pop it straight into the mouth, or hide it in a morsel of food. If you still see live fleas the next day, you may repeat the dose. Fast kill is only half the battle. Around 95% of a flea population exists off the animal as eggs, larvae and pupae in carpets, bedding and upholstery. For true control, pair 4Fleas Tablets with regular vacuuming and an environmental product containing an IGR to stop immature stages developing. Wash or change pet bedding frequently, and treat all pets in the household, as untreated animals act as reservoirs that can re-seed the problem. Johnson’s 4Fleas Tablets are the ideal “first strike” in a comprehensive flea strategy: immediate relief for the dog, zero mess for you, and total flexibility to integrate with your year-round prevention plan . Keep a pack on hand so you can act the moment fleas appear, then follow up with ongoing measures to keep them from returning. Adverse Reaction: For the first hour after administration, the pet may scratch more than normal. This effect is caused by the fleas reacting to the product. In very rare cases, this may present as transient signs of hyperactivity, panting, vocalisation and excessive grooming/licking. Transient neurological signs such as muscle tremors, ataxia and convulsions have also been reported in very rare occasions – very rare (less than one animal in 10,000 animals including isolated reports). If you notice any serious effects or other effects not mentioned here, please inform your veterinary surgeon. Contra-indications: None. Johnson’s 4fleas tablets can be safely used in pregnant or lactating females and breeding dogs. Do not use tablets after their expiry date (printed on the outer carton). Review: Works fast - The product works well but as stated does not prevent fleas from occurring, it does kill them fast. It slows them down allowing me to use flea comb to get rid of more. Review: Works - Same ingredients as Capastar flea tablets but much cheaper . I don’t like to use these but keep them in if my daily combing is failing . ## Features - To kill fleas on dogs over 11kg - No contra-indications - Safe to use with other flea and worm treatments, leaves no residue on their coat or in the home ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002ALITF0 | | Active Ingredients | Nitenpyram (57mg per tablet) | | Active ingredients | Nitenpyram (57mg per tablet) | | Age Range Description | Adult | | Allergen Information | Hypoallergenic | | Best Sellers Rank | 252 in Pet Supplies ( See Top 100 in Pet Supplies ) 5 in Dog Flea Drops | | Brand | Johnsons | | Brand Name | Johnsons | | Country Of Origin | United Kingdom | | Customer Reviews | 4.4 out of 5 stars 4,495 Reviews | | Dog Breed Size | Large | | Included Components | See Description | | Item Form | Tablets | | Item Type Name | Tablets | | Item Volume | 7.83 Fluid Ounces | | Item Weight | 57 Milligrams | | Item form | Tablets | | Item volume | 7.83 Fluid Ounces | | Item weight | 57 Milligrams | | Manufacturer | Johnsons Veterinary Products | | Manufacturer Part Number | 1614D085 | | Model Number | 1614D085 | | Pet Type | Dog | | Product Warranty | Statutory Rights | | Scent | Unscented | | Scent Name | Unscented | | Target Species | Dog | | Unit Count | 6 count | ## Product Details - **Active ingredients:** Nitenpyram (57mg per tablet) - **Age range (description):** Adult - **Allergen information:** Hypoallergenic - **Brand:** Johnsons - **Dog Breed Size:** Large - **Item form:** Tablets - **Item volume:** 7.83 Fluid Ounces - **Item weight:** 57 Milligrams - **Pet Type:** Dog - **Scent:** Unscented ## Images ![Veterinary Products 4Fleas Dog Tablets, Large, 57 mg, 6 Tablets - Image 1](https://m.media-amazon.com/images/I/81WcbzM6VNL.jpg) ## Questions & Answers **Q: What are the expire dates for these tablets?** A: we always have a packet in as our lab picks fleas up fairly regularly and have used 6-9 months apart. hope that helps **Q: how long does one tablet last** A: I'm not really sure how long it last just that it act almost immediately! I noticed the fleas dropping off after half an hour!...but it does say you can dose again the next day so I suppose it depends on how bad the animal as fleas and if their in carpets or animal bedding where they can jump back on animals. Hope this helps Linda **Q: What are the expire dates for these tablets?** A: The box I bought a month ago has an expiry date END 03/2022. **Q: Will these also kill lice?** A: I don't think so. Lice is not from the same family as fleas and therefore has different biology. It would be written on its leaflet if it was able to kill lice. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works fast *by D***F on 21 June 2026* The product works well but as stated does not prevent fleas from occurring, it does kill them fast.

I don’t like to use these but keep them in if my daily combing is failing . ### ⭐⭐⭐⭐ Easy to administer with a little soft cheese *by J***E on 7 October 2025* I give 4 stars as my dogs have just had their 1st tablet today. There does not appear to be any side effect but I’ll have to wait to ascertain whether the medication is effective. We received them very quickly and I administered them with little soft cheese.- no problem. After using for 3 days, there has been a big improvement with the dogs. They have stopped scratching and, thus far, we cannot see any fleas. We are using the tablets in conjunction with household spray. Hopefully, we are getting on top of the problem, thank goodness for the flea tablets. ## Frequently Bought Together - Johnsons Veterinary Products 4Fleas Dog Tablets, Large, 57 mg, 6 Tablets - Johnsons 4Fleas Tablets for Cats and Kittens, 6 Treatment Pack, 14D083 - Johnsons Veterinary Products 4Fleas Tablets for Puppies and Small Dogs Treatment Pack, 6 Count (Pack of 1) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/49402771-veterinary-products-4fleas-dog-tablets-large-57-mg-6-tablets](https://www.desertcart.ro/products/49402771-veterinary-products-4fleas-dog-tablets-large-57-mg-6-tablets) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-08-27*
