Rilexine is an antibiotic containing cephalexin which is particularly used for skin and urinary infections in dogs and cats. Sometimes long courses are required to completely clear infections of this type, so it is important to continue the whole course without a break. Sensitivity testing is recommended to ensure that Rilexine is appropriate for the causative organism. Rilexine tablets are beef flavoured for ease of administration and are happily taken by most dogs and cats.
Tablets for oral administration containing cephalexin (as cephalexin monohydrate PhEur) in three strengths:
Rilexine 75 containing 75mg cephalexin
Rilexine 300 containing 300mg cephalexin
Rilexine 600 containing 600mg cephalexin
Cephalexin monohydrate is a bactericidal antibiotic of the cephalosporin family, obtained by hemi-synthesis of the 7 amino-cephalosporanic nucleus.
Cephalexin acts by inhibiting the nucleopeptide synthesis of the bacterial wall. As a result bacterial destruction occurs. Cephalexin is not inactivated by β-lactamases produced by the Gram positive bacteria and which normally affect penicillins.
After oral administration, Cephalexin is absorbed through the intestinal barrier. The plasma peak is observed very quickly (T max. 1.5). Therapeutic skin levels are obtained within 2 hours.
Cephalexin is eliminated as an active form, mainly by the urinary route (85%).
Cephalexin is effective against a wide range of Gram positive and Gram negative bacteria including: Staphylococci, Streptococcus spp., Pneumococci, E. Coli, Klebslella spp, and Salmonella spp.
Treatment of the following infections caused by bacteria sensitive to cephalexin:
Infections of the urinary tract in cats and dogs (such as nephritis and cystitis).
Cutaneous infections (pyoderma) in dogs, including skin fold pyoderma impetigo, folliculitis, furunculosis and cellulitis.
15 mg Cephalexin per kg bodyweight twice daily (equivalent to 30 mg per kg bodyweight per day):
for a duration of 14 days in cases of urinary tract infection;
at least 15 days in cases of superficial pyoderma;
at least 28 days in cases of deep pyoderma.
To achieve this dosage, administer
one tablet of Rilexine 75 per 5 kg bodyweight
one tablet of Rilexine 300 per 20 kg bodyweight
one tablet of Rilexine 600 per 40 kg bodyweight
Rilexine tablets are well accepted by cats and dogs but may be crushed or added to food if necessary.
In severe or acute conditions the dose may be safely doubled.
Do not use in animals known to be hypersensitive to penicillins.
Do not use in rabbits, guinea pigs, hamsters and gerbils.
As with other antibiotics which are excreted mainly by the kidneys, unnecessary accumulation may occur in the body when renal function is impaired. In case of known renal insufficiency the dose should be reduced.
As with all other penicillins, cephalosporins may cause sensitisation (allergy) following injection, inhalation, ingestion or skin contact. Sensitivity to penicillins may lead to cross sensitivity to cephalosporin and vice versa. Allergic reactions to these substances may occasionally be serious.
1 Do not handle this product if you know you are sensitised, or if you have been advised not to work with such preparations.
2 Handle this product with great care to avoid exposure, taking all recommended precautions. Wash hand after use.

Below are some recent questions we've received regarding Rilexine Palatable Tablets for Dogs & Cats, including answers from our team.
My dog has been prescribed Relexine 600 tablets but we are having difficulty getting him to eat them, he is on a restricted diet so can't give inside a treat. Can we crush them into his normal dry food? Is it safe? Thank you.
These tablets are not coated and are perfectly OK to be given crumbled up into pieces. You can given them with food or water. However if mixed with dried food, the pieces will tend to fall to the bottom of the bowl and he will leave them. It would be much better to find a wet food to mix them with. Check with your vet if anything is suitable. If an allergy is suspected, then it is normally safe to give a completely different food item to what he has had before. (Often it is fine to give a little fish in oil, such as sardines, or duck, rabbit, venison etc. You must check with your vet about this first, but 99% of situations this is fine to do for dogs on restricted diets. I would add that the beef flavouring for the Rilexine tablets might be a concern in fact, so again you should check with your vet about this. Beef is often implicated in dietary allergies in dogs.)
Cn I give rilexine 75 palatable for my kitten age 2 mths cause by flu?
Cat flu is most commonly caused by Feline Herpes Virus-1 (FHV-1), or Feline Calicivirus (FCV). Rilexine would not have any effect on a flu virus but it is commonly used for secondary bacterial infections which are often associated with cat flu. It would be best for you to take your kitten to the vet to get them diagnosed and a suitable treatment in place.
Vaccination is the best way to protect your cat from the viruses mentioned, and this is usually carried out as a young kitten, and a booster given yearly.
We are able to supply prescription-only medication such as vaccines and antibiotics if you can send us a prescription from your vet, so it might be worth checking if this will save you some money.
My Makita got given this drug ..they are sensitive to certain medication and says on packet not to give to animals that are sensitive ....she had a fit after she took it ...is that due to the drug and the breed ? As I think the vet should of known this
Dogs which are "allergic" to penicillin should not have this drug. Otherwise it is very safe. This is the sensitivity the warning applies to. If a dog reacts to Rilexine it is very unlikely to have a fit, so I should think this is a coincidence. However, there is nothig wrong with asking your vet about this.
If you still feel there might be a problem, you can report this to the authorities by going to https://www.vmd.defra.gov.uk/adversereactionreporting/?AspxAutoDetectCookieSupport=1
Can these be safely given to pregnant and lactating bitches
Yes they are suitable for use on pregnant and lactating bitches.
what are the side effects of this drug please. My dog takes 1 and 1/2 tablet twice daily. She is a large german shepherd. She is listless and tired and hungry all the time while taking them. Is this normal please. X
Most dogs do not show side effects from this antibiotic at all. A few dogs will display signs of nausea and occasionally abdominal discomfort. These could account for how your dog's behaving, though increased appetite would not fit particularly. It is usual to give the tablets with a meal to reduce any side effects, so make sure you are doing this.
As in the use of any drug, one has to balance the benefits against any possible side effects. It is very likely that your dog will quickly return to normal when you stop the medication. It is possible of course that your dog's behaviour is nothing to do with the medication and is down to some other underlying problem. If in doubt you should of course talk to your own vet.
