Below are some recent questions we've received regarding 4Fleas Tablets for Dogs & Cats, including answers from our team.
Lori
It seems strange to me that the dosage for puppies and/or dogs under 11 kgs is exactly the same as for larger dogs. I'd have thought more body weight would require a higher dosage. If the dosage is the same for all of them, why is there a need to mention weight on the pack at all?
The tablets for large dogs contain 57mg of Nitenpyram and the tablets for small dogs and puppies contain 11.4mg of Nitenpyram so the larger dogs are receiving a higher concentration of active ingredient per tablet.
Janet
Can 4flea tablets be used for kittens who are 8 weeks and weighing 850 & 900 grams? I was going to use half a tablet but need to know if that's safe. The kittens are in good health, thanks
Giving half a tablet is likely to be fine although may not be enough to be effective where 1 tablet would be too much. I would advise using Fiproclear Spray since this can be used on any size of kitten from 2 days old.
Chloe
Can I put a standard 'spot on' on my pets after using this product to protect them for a longer period of time? I like how quickly these tablets kill the fleas but I would like to ensure that they do not get any more whilst I'm treating the home. Thanks
Yes you can do this and it makes perfect sense. Combining the tablets, spot-on and household spray is a very good idea. The only thing I would say is that even all of this may not get rid of all fleas immediately. Some eggs and larvae etc can be left all over the place and all of the products have a very high kill-rate for fleas, but they are not nuclear bombs. In order to keep them safe for cats and people, they cannot be as potent as we might like. They will do their job pretty soon though.
Debbie Simpson
Can I use flea tablets and frontline spot on together
These products can indeed be used together. The tablets should give a complete initial kill and the Frontline will help to provide more lasting protection. Ideally you should spray the house with a suitable insecticide too if fleas are a real problem. It is surprising how long it can take to get rid of all the fleas in a location if they have built up a large population.
Wendy Priestley
What do the tablets contain? And are they palatable?
The tablets contain the insecticide nitenpyram and they are reasonably palatable to most dogs and cats if mixed with food. They are not tasty enough to be given as treats. Individuals vary of course in how well they accept them. A tablet is extremely effective for 1-2 days, but it wears off rapidly after that.
Alice
My dog weighs 35 kg how many tablets should I give him?
The dose for any dog over 11kg bodyweight is just one of the standard tablets.
nicola
Can 4fleas b used on pregnant cat?
Also what worker can also be used?
There is a general presumption against giving any medication during the first third of pregnancy. Ideally you should try to observe this. Having said that, this product is regarded as safe to use during pregnancy and you should be safe to do so.
Elaine
Can I give these tablets to my cats on a regular basis to keep them flea free ? if so can you tell me how often and how many
The tablets can be given regularly, at a maximum of 1 tablet per day. It is also advisable to use a household treatment at the same time as although these tablets will kill the fleas on your cat, there still may be fleas in carpets, bedding or furnishings that the fleas may be, which may then get back onto your cat at a later point. Virbac Indorex Household Flea Spray is a popular choice.
Kirsty
I have a cat and a dog I'd like to treat , can my animals be harmed by the product once treated, ie if my dog licks my cat or vice versa can they be harmed?
There is no concern about another pet licking the treated pet. This product is very safe and you do not need to be unduly concerned. However to control the fleas, you will probably also need to treat the environment with a household spray like Indorex to reduce the numbers of more fleas jumping on your pets.
Cook
How often do,you need to give these tablets?
There is no fixed answer to this question, because it depends on how many fleas there are in the environment of the pet. These tablets appear to be very effective indeed for any fleas on the animal at the time of giving the tablet, but they provide no lasting protection at all. This helps to make them safe for your pet as the drug does not persist in the body, but if a flea jumps onto your pet the day after treatment, that flea might be completely unaffected. The modern spot-on treatments persist for a few weeks, killing fleas for the whole time. These flea tablets are probably more effective for a few hours and might well kill every flea, but then they rely on you spraying around the house etc with a household insecticide to kill any other fleas present. The tablets are particularly good for treating a new pet before bringing it into a new home, and for combining with environmental flea treatments (including Program, which is also a tablet and very safe for pets).
