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.

Q & A

Below are some recent questions we've received regarding Isaderm (formerly Fuciderm) Gel for Dogs, including answers from our team.

Paw application


How long after applying will the gel be absorbed and my dog is safe to lock her paws. My dog has false pads with hyperkeratosis. Is this an effective treatment?

  • VioVet Staff

This product contains anti-inflammatory and anti-bacterial medication that is intended for treating dermatitis in dogs. Unless there is an inflammatory or infectious component to your dog's hyperkeratosis then it is unlikely to help with the condition.
It starts to be absorbed by the skin pretty quickly but you should still deter your dog from licking the site, any licking of areas with dermatitis will only worsen the problem.
It is also a prescription only medication so you will need a written prescription from your vet to purchase it with us.

If he was to lick the area


Hi would my dog be ok if he had licked the area were the cream had been used

  • VioVet Staff

A small amount of this cream licked off should cause no issues but if your dog is routinely ingesting the product then this could be dangerous, plus it would have no effect on the skin it is meant to stay on. I advise trying to prevent the licking such as with a buster collar.

11 September 2020 at 9:10pm



Is this product painful for a dog? My vet has prescribed me to use this on my dogs superficial open wound near his mouth, I don't know if he will find it painful when applied, like TCP for a human would be.

  • VioVet Staff

This product should not be painful when applied correctly. It helps to reduce inflammation and treat any infection on skin it is applied to.

How long does it take to work on dogs?

  • VioVet Staff

The ingredients in Isaderm will start working within a few hours and start to fade after 12 hours, therefore twice daily application is often required. You may not see an improvement in your pet's condition for a few days as the ingredients will take time to overcome the disease your pet has. For example, an infection will require repeated doses to clear.
You should always follow your vets advice regarding doseages and course length.

Alison Johnson

Can I use this cream on a small patch of irritated skin under my dogs neck ...think her collers been rubbing

  • VioVet Staff

Hello Alison,

Isaderm contains an antibiotic and a steriod which is usually used in infections and to relieve itching. Isaderm is a POM-V product and we do require a prescription for this medication, prior to dispensing. I would advise you to have a consultation with your veterinary surgeon to see if this cream would be suitable.

I hope this helps.

Ear infection - Bullmastiff


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

  • VioVet Staff

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

VioVet Visitor

Can it be used on open wound

  • VioVet Staff

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?

VioVet Visitor

What side effects or reaction to isaderm

  • VioVet Staff

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.

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?

  • VioVet Staff

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

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

  • VioVet Staff

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.
