Program Suspension for Cats

A once-a-month oral suspension which has the ability to control flea populations. As an insect development inhibitor, PROGRAM does not kill adult fleas, but effectively and safely controls flea populations on your pet through a mode of action which breaks the flea’s life cycle at the egg stage.

In addition to this flea treatment you may require an additional household spray to combat fleas which may not have yet hatched or dormant fleas in and around the house. Please click here to see the range of household sprays available.

Below is the product datasheet. This has been provided by the manufacturer and should always be provided with the medication.

For the prevention and lasting control of flea infestation. Program is effective against the dominant flea species Ctenocephalides felis and C. canis. Program suspension can be administered to all cats including pregnant cats and kittens taking solid food.

Dosage and administration

The minimum recommended dose rate is 30 mg/kg/month. This is achieved by giving:
Cats and kittens up to 4.5 kg—content of 1 ampoule containing 1.9 g of suspension/month
Cats over 4.5 kg—content of 1 ampoule containing 3.8 g of suspension/month.
To be fully effective the suspension must be administered together with food.
Shake the ampoule prior to opening.
The suspension should be added into approximately half of the food ration. The rest of the food should be presented when all the dose has been eaten. If several cats are treated, ensure that each cat is fed individually. The product can also be administered by squeezing the suspension directly from the ampoule onto the back of the cat's tongue after feeding.
To open the ampoule first hold the base tab (which has writing on it) and flick the pack. Then twist off the top portion and squeeze the ampoule several times to administer the suspension.
To prevent flea infestations Program should be administered at monthly intervals for at least six months during the flea season, starting two months before fleas become active.
If the cat is already infested with fleas, no viable flea eggs are produced from 24 hours after the first administration. The speed of elimination of the infestation is dependent upon the number of flea larvae and pupae in the environment when treatment starts and climatic conditions.
If cats have a high level of flea infestation at the start of the treatment, it may be necessary to administer a flea adulticide during the first one to two months. In cases of severe hypersensitivity, further use of an adulticide may be needed.
It is essential that all cats and dogs (except unweaned puppies and kittens) living in a household are treated with Program to stop flea reproduction.
For dogs, use Program tablets.

Further information

Program contains lufenuron, a benzoylurea derivative.
After administering Program orally to the cat, the active ingredient is quickly absorbed. Sufficient absorption is only achieved if administered on a full stomach. The low excretion rate assures an effective concentration of the active ingredient in the blood for one month.
Fleas take up the active ingredient through the blood and transfer it to their eggs. The formation of larval chitin structures, a process typical to insects, is blocked and the development of their numerous offspring is stopped. A new infestation of the home with fleas is prevented.
Fleas picked up by the cat outside the home environment are prevented from causing a new infestation of the home.

Ask Your Own Question

Use Program suspension with Effipro spot on

18th Jul 2017
Raymond Mayes
  • VioVet Customer Since: September 2012
  • From: Northumberland, United Kingdom

Can you use Program suspension at the same time as Effipro spot on; to disrupt the flea life cycle and also have some instant knock down of adult fleas?

  • Veterinary Advisor

It would be safe to give the two together since they are different classes of drugs. However it would not help that much to use the Program as well as Effipro. Program works by the adult fleas ingesting the active ingredient (Lufenuron) in the cats blood which is then transferred to their growing eggs stopping them from becoming adults. Effipro (Fipronil) will kill all fleas within 24-48hrs so the adults are likely to be dead before many affected eggs are layed. Usually you don't need to use more than one treatment on your pet at once but it is important to treat your pets environment (bedding, carpets, sofas etc) with a spray such as Indorex since many fleas live in the environment and will jump back onto your pet.

Flavour of suspension

21st Aug 2014

Our cat is mainly feral but comes in the house. I've had to give up drops behind the head treatments as she's too quick at noticing when it touches and runs out. She's a spitfire to pick up, scratches and bites prove it when I get close enough to try!

She is also a small eater and can be quite picky. Above also means I won't be able to squirt it into her mouth.

Questions are -
Is the treatment flavourless or does it have a cat enjoyable flavour which might temp her to eat her food with it in anyway?

  • Non-Executive Director

The flavour and odour of this product seem pretty neutral to cats. A hungry cat will eat food with it in quite happily. A fussy or nervous cat will be able to tell that the food is not "normal" and will not be inclined to eat it. The best way round this is to offer it at a time when the cat is particularly hungry (miss the previous meal perhaps) and then add it to a new food which has not been offered before. Ideally this should be something the cat really enjoys, though this is difficult to predict when you have never tried it before! You could try some mashed up prawns, liver pate, tuna in oil, stir-fried chicken wings or whatever. Cats as you describe are never easy. I would however suggest not giving too much food at one time - over-feeding (relative to their appetite, not what you think is a portion) is always the way to produce a fussy cat. A regularly truly hungry cat is never fussy.
