Isaderm Gel (previously called Fuciderm Gel) is a skin gel used to treat infected and itchy skin problems in dogs. Isaderm contains an antibiotic (fusidic acid) and a steroid (betamethasone) which between them can kill infection and relieve itching. The antibiotic is able to penetrate into skin to kill bacteria below the surface. The steroid also penetrates into skin and helps to reduce further licking and scratching which some dogs will do excessively, making the problem much worse. Isaderm Gel is effective for hot spots, wet eczema (exudative dermatitis) and superficial pyoderma. A thin layer is applied twice daily for several days usually. Gloves should be worn to apply Isaderm (or the operator will receive a treatment too!)

Shelf life once immediate packaging is opened: 6 weeks.


Contains: Active substances:

Fusidic acid 0.5% w/w

Betamethasone 0.1% w/w (as the valerate ester)


Methyl parahydroxybenzoate (E218) 0.27% w/w

Propyl parahydroxybenzoate (E216) 0.03% w/w

Excipients: Carbomer, polysorbate 80, dimeticone, sodium hydroxide, purified water.

White gel.


For the topical treatment of surface pyoderma in the dog, such as acute moist dermatitis ('hot spots') and intertrigo (skin fold dermatitis).

Dosage and administration

Apply a quantiity of the gel to the affected area, twice daily for a minimum period of 5 days. Treatment should continue for 48 hours after the lesion has resolved. The treatment period should not exceed 7 days.

If there is no response within 3 days, or the condition deteriorates, the diagnosis should be re-evaluated.

Contraindications, warnings, etc

Do not use in animals with hypersensitivity to any of the components. Discontinue use if hypersensitivity develops to the product.

Do not use for the treatment of deep pyoderma as glucocorticoids are contraindicated in this condition.

Do not use where fungal infection is present.

Do not apply to the eye.

Special warnings for each target species: The dog should be prevented from licking treated lesions and so ingesting the product. Where there is a risk of self-trauma, preventative measures such as the use of an Elizabethan collar should be considered.

Special precautions for use in animals: Betamethasone valerate can be absorbed percutaneously and may cause temporary suppression of adrenal function. Prolonged treatment or the treatment of large surface areas should be avoided.

Avoid eye contact.

Special precautions to be taken by the person administering the veterinary medicinal product to animals: Corticosteroids may produce irreversible effects in the skin; they can be absorbed and may have harmful effects, especially with frequent and extensive contact, or in pregnancy. Always wear single-use disposable gloves when applying the product to animals.

Wash hands after applying the product.

Adverse reactions: Anti-inflammatory corticosteroids, such as betamethasone valerate, are known to exert a wide range of side effects. Whilst single high doses are generally well tolerated, they may induce severe side effects in long term use and when esters possessing a long duration of action are administered. Dosage in medium to long term use should therefore generally be kept to the minimum necessary to control symptoms.

Steroids themselves, during treatment, may cause Cushingoid symptoms involving significant alteration of fat, carbohydrate, protein and mineral metabolism, e.g. redistribution of body fat, muscle weakness and wastage, and osteoporosis may result.

During therapy, effective doses suppress the hypothalamo-pituitreal-adrenal axis.

Following cessation of treatment, symptoms of adrenal insufficiency can arise and this may render the animal unable to deal adequately with stressful situations.

Locally applied steroids may cause thinning of the skin.

Corticosteroids may delay wound healing and the immunosuppressant action may weaken resistance to or exacerbate existing infections. In the presence of viral infections, steroids may worsen or hasten the progress of the disease.

Gastrointestinal ulceration has been reported in animals treated with corticosteroids, and gastrointestinal ulceration may be exacerbated by steroids in patients given non-steroidal anti-inflammatory drugs and in animals with spinal cord trauma.

Steroids may cause enlargement of the liver (hepatomegaly) with increased serum hepatic enzymes.

Use during pregnancy and lactation: Corticosteroids are not recommended for use on pregnant animals. Administration during pregnancy may cause abortion or early parturition.

Interactions: None known.

Overdose: For possible signs see Adverse reactions.

Incompatibilities: None known.

Do not refrigerate or freeze. Do not use after the expiry date stated on the carton.

Shelf life of the veterinary medicinal product as packaged for sale: 3 years.

Ear infection - Bullmastiff

26th Nov 2015

hello, my dog suffers with his ears as hes a bullmastiff, this is the cream i can use for inside them isnt it?

Thank you

  • Brand Manager

Hi Lianne, I'd recommend taking him to your vet if your dogs ears are infected, as he will be able to prescribe an appropriate treatment for him. This may or may not be Isaderm, but as Isaderm is a prescription only product, we can only supply it if we receive a copy of a prescription from your vet. If your dog requires ongoing treatment, we may be able to save you a good amount money if you ask your vet for a repeat prescription.

Once the infection has cleared up, regular cleaning with a product such as RestAural will help to prevent further infections, but it should not be used on infected ears with broken skin, so it's important to speak to your vet first, and find out why he has trouble with them. I hope this helps!

Can it be used on open wound

Can it be used on open wound

  • Non-Executive Director

It depends how open the wound is. This is not intended to be used on a "lacerated" wound - where there is a deep cut through the skin. It can be used on an eroded or superficially ulcerated wound which might well look very sore and be weeping/oozing serum and some blood. It helps to reduce self-trauma, usually caused by excessive scratching/licking/biting by the dog itself. If in doubt, you must always check with your own vet about this sort of thing.

Side effects?

What side effects or reaction to isaderm

  • Non-Executive Director

Usually there are no side effects. If you were to cover large areas of skin with it (especially if this was done for many days or even weeks) then the steroid from the gel is absorbed into the body and will have an effect (initially increased thirst and hunger, but then changes in the skin, fat deposits, muscles etc etc). However if it is used in the normal way for a few days or a week or so and over a smallish area of skin, it is very unlikely that there would be any side effects at all. Generally speaking the most effective medicines are those with the greatest potential for side effects. Medicines with "no side effects" are generally much more feeble in what they accomplish when they are really put to the test, despite what we might wish.

11th Sep 2015

My cat had had his anal glands drained, the vet prescribed me isaderm to use on his bottom. I have been using it twice daily for two days and his bottom is still very sore, is there a chance it will get better soon or is another trip to the vet required?

  • Non-Executive Director

This should have improved significantly by now. If this is still bothering him and looking sore, I would suggest a vet check in case there is infection within the glands (too deep for the Isaderm to reach) or some other problem persisting.

Fusiderm gel prescription free alternative

26th Aug 2015
Mrs judith bright

My 6yr old westie has been savagely biting the base of his tail and doing the 'three-legged tickle dance'! He has been flea treated but i found 2 on him. Both house and bedding are clear.
He was previously prescribed Fusiderm gel for the same irritation but i cannot afford the vets fees now. Is there an effective alternative version of the gel that is prescription free?
Thank you

  • Non-Executive Director

Regrettably there is no equivalent product which can be bought without prescription. Your cat is probably allergic to flea bites and so the occasional bite is causing a dramatic itching effect. This will actually settle down if you treat for fleas thoroughly, diligently and for long enough. Getting rid of all the fleas is actually not an easy task and it takes some while for all the flea eggs lost in nooks and crannies around the home to hatch out and develop. If you have treated the house extremely well then this will be dramatically reduced, but you will not get every one. Almost certainly the occasional flea will make it onto your cat and manage to bite before being killed off by the flea treatment you should be regularly using on your cat. Eventually you will succeed in getting the flea population to such a low level that they are not a problem for your cat and then the skin will settle down. Then you will never see any fleas, though the occasional one may be present at times. This takes some time and so you must continue to treat your cat for fleas, while making sure you treat the house very well. It is possible, but not as easy as most people expect, which is why this sort of skin problem occurs and tends to persist.

Use on wound

on open skin

Can I use isaderm on open wounds

  • Non-Executive Director

It depends how open they are. A raw looking patch of skin which is "ulcerated" and prone to self-trauma (licking/biting/scratching) is well suited to this product. A deep cut is much less appropriate. Your vet should advise you on this because it is a prescription product anyway.

Vets prescription

20th Aug 2015

My vet in Spain has prescribed fuciderm for my dog.We are moving to UK so will I be able to buy it from you using my Spanish vets prescription bu for delivery to UK? Thank you.

  • Non-Executive Director

We can only sell prescription products into the country where the vet is qualified to prescribe. We can post this to Spain on your current vet's prescription, or you need to get a UK practicing vet to provide a prescription if we sell it into the UK.

Mandy Waite

hi my dog Billy a jack Russel was prescribed this today and has been very sleepy is this a side effect ??

  • Non-Executive Director

This product is unlikely to have this as a side-effect. Even licking off a large amount of it would not normally cause this. There might be another cause, or it might just be coincidence and he has just been a bit sleepy. If you are worried, you would have to ring your own vet.

Cat skin allergy - fuciderm ?

17th Jul 2015
Caryl Longland
  • VioVet Customer Since: May 2013
  • From: Dorset, United Kingdom

My cat has an allergic dermatitis- he is a thick haired cat possibly of Maine coon origins - about 2 years old and weighs 5 kilos.we have recently changed his diet to James well beloved fish dry food for adults which he loves and the scratching has decreased - however he has one or two scabby bald patches on his head -
Can fuciderm ointment for dogs be used to treat the patches or is there a similar one for cats ?

  • Non-Executive Director

This ointment is used on cats but it is prescription-only, so your vet has to provide a written prescription before we can sell it to you. Your vet would then advise on usage.
