Droncit contains the active drug Praziquantel and is one of the most safe and effective treatments for canine and feline tapeworms. Any dog that scavenges when out walking can easily become infected with tapeworms. Cats are also at risk, becoming infected from hunting and eating similarly infected prey - mice and birds are highly susceptible to worms, so consuming them can be hazardous. Both cats and dogs can also pick up a specific type of tapeworm from swallowing fleas when they groom themselves. A single dose of Droncit is all that is required to eradicate any tapeworms present in the gut. Licensed for use in dogs and cats.

Droncit Spot-On is a convenient, easy to administer treatment for tapeworms, probably the most common worms affecting cats. Droncit Spot-On can be used alongside flea preparations, although it is not advised that both be applied on the same day. Droncit contains the active ingredient Praziquantel, which is the same ingredient found in many expensive prescription worm treatments. For most cats, one application every 3 months would be advised.

A white tablet containing 50 mg praziquantel.


For the treatment of adult tapeworms in dogs and cats. The tablets are effective against both immature and mature forms of adult tapeworms in both dogs and cats.
The product is a highly effective treatment against all the common species of tapeworm infecting dogs and cats in the United Kingdom and Ireland including Echinococcus granulosus, Taenia ovis, Taenia pisiformis, Taenia multiceps, Taenia hydatigena, Taenia taeniaeformis, and Dipylidium caninum. Droncit is also effective against Echinococcus multilocularis (As a precautionary measure to prevent the establishment of Echinococcus multilocularis in the UK and Ireland, it is recommended that all dogs and cats entering the country be treated with praziquantel.

Dosage and administration

The recommended dosage rate is 5 mg/kg body weight. This corresponds to 1 tablet per 10 kg bodyweight.

Dogs: Body weight
2.5 - 5kg 1/2 tablet
6 - 10kg 1 tablet
11 - 20kg 2 tablets
21 - 30kg 3 tablets
Over 30 kg pro rata
Adult cats 1/2 tablet

Oral administration.
The tablets are administered by opening the animal's mouth and pushing the tablet over the back of the tongue so that it cannot be rejected. Alternatively, a tablet can be wrapped in a piece of meat or butter and offered to the animal or crushed and mixed with the food.
A single dose is all that is required. However, for dogs in rural areas and for packs of hounds this dose should be repeated every four weeks to ensure that newly acquired tapeworms are destroyed before reaching maturity. Dosing must be associated with strict control of the dog's diet to ensure that uncooked offal is not eaten.
Use during pregnancy and lactation
The product may be administered to pregnant females. It is safe to the female herself, to the unborn foetus and to the newborn young.

Contra-indications, warnings, etc

Do not administer to dogs weighing less than 2.5 kg.
Do not administer to unweaned puppies and kittens, as such animals are rarely infected with tapeworms.
Fleas serve as intermediate hosts for one common type of tapeworm - Dipylidium caninum. To avoid reinfection with this parasite, flea control of the animal and its housing should be carried out at the same time. Unless flea control is complete an infected flea population may survive: i.e. re-treatment of the animal may be necessary.
As a precautionary measure to prevent the establishment of Echinococcus multilocularis in the UK and Ireland, it is recommended that all dogs and cats entering the country be treated with praziquantel.
Any part used tablets should be discarded.
User safety
In the interests of good hygiene, persons administering the tablets directly to the animal, or by adding them to the animal's food, should wash their hands afterwards.
Environmental safety
Any unused veterinary medicinal product or waste materials derived from such veterinary medicinal product should be disposed of in accordance with local requirements.

Pharmaceutical precautions

Further information

Praziquantel is a pyrazino-isoquinolin derivative, with anthelmintic activity. ATC Vet Code: QP 52 AA 01. The spectrum of action of praziquantel covers all the important species of cestodes in dogs and cats. It specifically includes all Taenia species occurring in dogs and cats, Multiceps multiceps, Joyeuxiella pasquali, Dipylidium caninum, Mesocestoides species, Echinococcus multilocularis and E. granulosus. Praziquantel is effective against all stages of development of these parasites occurring in the intestines of dogs and cats. Praziquantel impairs the normal tegument function of the parasite, making it permeable to excessive glucose loss and thereby more easily attacked by proteolytic enzymes. Because of this, whole tapeworms including the scolex are very rarely passed in the faeces following administration of the drug. Disintegrated and partially digested fragments may occasionally be seen in the faeces. Praziquantel is rapidly absorbed by the animal and metabolised by the liver. It is excreted, entirely as metabolites, in the urine and faeces.

Figure 1: Opening a tube

Part the hair on the cat’s neck at the base of the skull until the skin is visible. See figure 2.

Application to cat
Figure 2: Administration

Place the tip of the pipette on the skin and squeeze firmly several times to empty the contents directly onto the skin. Application at the base of the skull will minimise the opportunity for the cat to lick the product.
To minimise the possibility of run-off after application of more than one pipette, it is advised that the applications should be performed slowly to allow absorption and that it may be advisable to allow the contents of the previous pipette to be absorbed before applying another.
Tapeworm infection is certain to re-occur unless control of the intermediate hosts such as fleas, mice, etc, is undertaken.
Flea control
Flea infestations can be controlled by the regular use of effective flea control remedies.
Mice control
If cats roam and hunt, contact with, and consumption of, mice and subsequent re-infestation with Taenia taeniaeformis is impossible to prevent.
It is recommended to re-apply Droncit Spot-On when signs of tapeworm infection re-appear or at monthly intervals.
Use During Pregnancy and Lactation
There are no contra-indications against use during pregnancy and lactation.

Contra-indications, warnings, etc

Further information

The Active Ingredient
Praziquantel, the active ingredient of Droncit® Spot-on is a pyrazinoisoquinoline derivative used widely as an anthelmintic for both human and veterinary medicine. The chemical name for this substance is 2-cyclohexyl-carbonyl[1,2,3,6,7,11b] hexahydro-4H-pyrazino-[2,1-a]isoquinolin-4-one[1]. ATCVet Code: QP52AA01.
Praziquantel is effective against all stages of development of intestinal tapeworms. The substance is very rapidly absorbed and distributed throughout the parasite. Both in vivo and in vitro studies have shown that praziquantel causes severe damage to the parasite integument, resulting in contraction and paralysis. There is an almost instantaneous tetanic contraction of the parasite musculature and a rapid vacuolisation of the syncytial tegument. This rapid contraction has been explained by changes in divalent cation fluxes, particularly calcium.
Praziquantel is absorbed very rapidly and almost completely in the stomach and small intestine. Studies of the behaviour following oral administration have been conduced in rats, dogs, monkeys, sheep and humans. Depending on species, maximum serum levels are reached within 0.3 to 2 hours. The chemical is evenly distributed to all organs. The elimination half-lives of 14C-praziquantel and its metabolites are between 2 and 3 hours in rats, dogs, monkeys and sheep.
Praziquantel is rapidly metabolised in the liver in both humans and animals with the 4-hydroxycyclohexyl derivative as the main metabolite. Praziquantel is completely eliminated from the body within 48 hours; irreversible binding to body constituents has not been observed. Elimination is in the form of metabolites with virtually no parent compound excreted. Between 40% and 71% of the substance is eliminated in the urine and 13%-30% in the faeces.

Droncit Wormer for cats

Janet Harris

  • VioVet customer since 2017
  • From: Pen-y-bont ar Ogwr, United Kingdom

Will this product treat roundworm as well as tapeworm?

  • Veterinary Advisor

This product is effective only against tapeworm. Drontal is effective against both roundworm and tapeworm though.

How often

Samantha Knox

  • VioVet customer since 2017
  • From: Tyne and Wear, United Kingdom

How often do you worm the cat with droncit spot on please

  • Veterinary Advisor

For most cats once every 3 months should be sufficient. However if they are hunters and catch lots of mice etc then application once a month is advised.

Scalibor collar and other treatments

Justine Rogers

  • VioVet customer since 2016
  • From: Matera, Italy

My dog lives in Italy where there is leishmaniasis and a Scalibor collar is imperative. Although it should alleviate fleas, I initially need another effective one-time treatment. What other flea treatment is safe alongside Scalibor. Also a wormer... is Droncit ok...a lot of strong treatments! What would you suggest?

  • Non-Executive Director

Droncit is just for tapeworms. Drontal Plus is a multi-wormer which is effective against tapeworms and round worms too. This is safe to use with all the other products you are talking about using. If you want to give a one-off treatment for fleas, then you can use a spot-on product like Frontline or Advantage, or give a tablet such as Capstar.

Treating for tapeworms

VioVet Visitor

My dog has advocate as he will not take worming tablets. Iv crushed them, hidden them in cheese, wrapped them in meat, and he still knows they are there and refuses to take them. Im concerned about tape worm and thought about droncite spot on but cant find anything for a 20k dog

  • Non-Executive Director

Droncit (or any other brand of the drug praziquantel) is perfect for treating tapeworms in a dog which is also receiving Advocate. However there are no spot-on forms of this drug for use in dogs, they are just for cats. Dogs can be given tablets (which is extremely difficult for you) or can be given an injection by your vet. I do not think you have any other choice, apart from not treating for tapeworms at all. Usually in dogs you know if your dog has a tapeworm because segments of worm are seen near the anus. If you do not see these, then your dog is almost certainly clear of them. Diligent flea control (they can carry tapeworms), avoiding feeding fresh offal and not allowing scavenge of wild animal carcasses will normally control tapeworms anyway.

Can I administer to a 9wk old kitten? How much of tablet? How often?

  • Non-Executive Director

This tablet treats just tapeworms, it is not a general multi-wormer. It is very unusual for a 9 week old kitten to get tapeworms, so I wonder if you have the correct tablet. You might intend to give Drontal which has a similar name but is the usual multi-wormer. If you do indeed need to give Droncit, the dose is one tablet per 10kg bodyweight. You would have to weight the kitten and see how much it weighs. It would then be a matter of dividing up the tablet as needed, though it might be quite tricky to do. One eighth of a tablet would be the correct dose for 1.25kg which might be about the weight of your kitten.

If you want to give Drontal then there is a liquid which is easier to give in smaller doses. Otherwise the dose for the cat tablets is one tablet per 4kg, or a quarter tablet per kg.

Salivating cat


Iv applied the droncit spot on,is it normal 4 the cat 2 dribble lots

  • Brand Manager

If your cat has managed to lick the application site soon after application, this can cause excessive salivation but this should stop within a few hours. The product is bitter tasting but not harmful despite causing dribbling and shouldn't need treatment. For future applications, it might be worth trying to apply it while your cat is asleep or distracted with a meal, to give the product time to dry. If you have more than one cat, prevent them from grooming each other until the area has dried.

If your cat is still dribbling after a few hours and you are concerned, you should get in touch with your vet.

Advocate and Droncit


Hi, I gave my adult cat Advocate 3 days ago. I have just discovered she has tapeworms. Is it ok for me to give Droncit now or do I need to leave a time-gap? Thanks in advance!

  • Non-Executive Director

It is perfectly OK to give these two treatments at the same time, or at different times. They work independently of each other and do not react adversely if given at or near the same time.

15 February 2015 at 6:29pm

Droncit tablets and effipro flea and tick drops

VioVet Visitor

Can I give my 10 month old dog effipro flea and tick drops the same day as I give him droncit tablets?

  • Non-Executive Director

Yes this is perfectly OK (but note that Droncit is just for tapeworms. Drontal is also safe to give with Effipro and is a multi-wormer which treats roundworms as well as tapeworms).

Use on pregnant cat


Can this spot on wormer be used for pregnant cat?

  • Brand Manager
