Xenex Ultra Spot on for Small Animals

  • 6 x Tubes £19.90


Xenex Ultra is used to control Fleas, Flies, Lice and Mites. It acts on the surface of the animal killing and repelling insects and similar creatures. It has no effect on worms or any internal parasites. It can be used on Guinea Pigs, Rabbits, Hamsters, Rats, Chinchillas, Mice and all small rodents. It should not be used on cats or ferrets.

Xenex is applied as drops onto the skin, and the correct dose for smaller animals can be judged by counting the number of drops. A mouse weighing 50g would need just one drop, larger animals require more. Full dosing instructions are provided. The full contents of one vial will treat 3kg and there are 6 vials in the pack.


For use in Rabbits, guinea pigs, rats, hamsters, chinchillas, mice, other small rodents. Not cats, not ferrets.

Indications for useFor the prevention and control of infestations caused by: flies (adult and immature stages), fleas, ticks and lice. Xenex Ultra should be used as part of an insect control programme. Ensure that pets are kept in clean, dry housing which is free of faeces and urine. Fly strike is caused by flies laying their eggs in the wet or sore areas which can develop around the anus of pets. These sores often develop as a result of diarrhoea caused by poor diet and hygiene. Ensure that the animal is fed the correct diet, regularly check it for faeces soiling and bathe if necessary.Contra-indicationsDo not use on Cats. This product is toxic to and may kill cats.Undesirable effects (frequency and seriousness)A small number of animals may experience an irritation on the skin where the solution has been applied. In most cases dermal irritation is limited to a mild and occasionally reddened area at the site of application. Should this occur bathe immediately with a mild non-insecticidal shampoo and the reaction normally resolves without further consequence. Do not reapply Xenex Ultra Spot On to animals which react in this way. More rarely severe dermal lesions can occur which include redness, weeping open sores and varying degrees of local fur loss. Should this occur veterinary advice should be sought. These lesions usually respond well to appropriate symptomatic treatment, which may include topical corticosteroids +/- antibacterials.Very rarely small rodents may demonstrate signs of Central Nervous System disturbance such as ataxia and tremors. If this occurs veterinary advice should be sought immediately and diazepam or pentobarbitone sodium may be administered to control convulsions.Special precautions for useWash hands after use. Wash off any splashes immediately. Avoid contact with eyes. If splashed in the eye, wash with plenty of water.Users carrying out multiple applications should wear protective gloves made of neoprene or nitrile of a minimum thickness of 0.3mm.Do not handle the area of application for 3-6 hours after treatment.Treated animals should not be allowed to sleep with people particularly children.This product is poisonous to cats. Ensure that cats do not groom the site of application on a treated animal, if this occurs separate the animals and consult a vet.Use during pregnancy and lactationNo data available. Do not use in pregnant and lactating animalsInteraction with medicaments and other forms of interactionNone known.Method of administrationIn normal circumstances application every 2 weeks is sufficient; however, some individual animals are particularly prone to fly strike and in these cases weekly application is advisable.It is very important to weigh animals accurately as overdosing can be harmfulRemove a tube from the packaging and snip off the end of the nozzle with a pair of scissors. Try not to get the solution on the fingers whilst handling the product. Part the fur of your pet either between the shoulder blades at the back of the neck, to either side of the spine or (specifically for fly strike control), on the back and the rump at the base of the tail (avoiding the anus and genitals). Squeeze the appropriate number of drops onto the exposed skin. Avoid applying the solution in a single site. Whenever possible divide the appropriate dosage and apply to several different places on the skin.For how many drops to use see the table below.

DO NOT OVERDOSEWhen applying doses that do not require the application of a full tube, the following procedure is recommended to avoid overdosing. Holding the tube with the plastic tip pointing upright; cut the nozzle off with scissors at the point where it joins the tube tip. Prime the tube by inverting it over a folded piece of tissue paper and, squeezing gently, expel the first drop that comes out of the tube. (Discard the soiled tissue with the usual household refuse). With further gentle squeezing, individual, uniform drops may now be expelled from the tube (which contains approximately 30 such drops in total).Observe the animal closely for 15 to 30 minutes after application. If any signs of skin irritation or behaviour changes occur, immediately wash off the product using a mild non-insecticidal shampoo. Discontinue use. Should adverse signs persist after bathing veterinary advice should be sought.It is very important to dispose of any unused product in accordance with the instructions below.DO NOT KEEP OPEN TUBES FOR FUTURE USE.Overdose (symptoms, emergency procedures, antidotes)There are no specific antidotes for permethrin toxicity; treatment is symptomatic. In cases of suspected overdose, remove as much of the topical formulation as possible, by washing the site of treatment with a mild detergent and cool water (warm water may facilitate systemic absorption transdermally). If any unusual neurological signs are noted, treat according to severity. In markedly intoxicated animals (e.g. where hyperaesthesia, marked muscle fasciculations / convulsions are observed), reduce environmental stimuli (e.g. confine animal in quiet, darkened area). Diazepam and / or pentobarbitone sodium may be useful for controlling convulsions. Monitor body temperature: hypo- and hyperthermia can occur. If significant, recent oral ingestion is suspected, administer activated charcoal suspension.Special warnings for each target speciesDo not use in animals less than 16 weeks of age. Do not overdose. Weigh animals carefully and accurately, apply the correct dosage.Withdrawal periodsNot applicable. Do not use on animals intended for human consumption.Special precautions to be taken by the person administering the product to animalsWash hands after use. Wash off any splashes immediately. Avoid contact with eyes. If splashed in the eye, wash with plenty of water.Users making multiple applications should wear protective gloves made of neoprene or nitrile of a minimum thickness of 0.3mm.
