Isaderm Gel

(Formerly Fuciderm Gel)

Isaderm is a white, translucent gel and is for the topical treatment of skin diseases such as wet eczema (acute moist dermatitis) and intertrigo (skin fold dermatitis) on dogs.

It is supplied in 15g or 30g tubes of gel.

The gel contains fusidic acid and betamethasone. Betamethasone is a corticosteroid and an anti-inflammatory and the fusidic acid is an anti-biotic.

Isaderm Gel is a prescription item and will be sent once a valid prescription is received. Please follow the instructions given by your vet.

How to apply: First, the hairs that are covering the lesions need to be gently clipped. The area then needs to be thoroughly cleaned with an antiseptic wash before every daily application of the gel. A thin layer of gel needs to be applied twice daily for a minimum of 5 days. After the lesion has resolved, treatment will still need to be given for 48 hours.

The dog should be prevented from licking the treated areas as risk of ingesting the product.

Corticosteroids can produce irreversible effects in the skin. Once absorbed, it can have harmful effects. Pregnant women need to take extra care to avoid accidental exposure. 

Do not apply to the eye.

Do not use where a fungal or viral infection is present.

Isaderm Gel is a prescription item and will be sent once a valid prescription is received.

If you see the "prescription required" sign next to an item you’d like to order, it means the item can only be issued with a prescription. While you can add these items to your shopping cart and pay for them along with other non-prescription products, we can’t dispatch them until we’ve received a prescription.

Excellent service and reasonable prices


I have a very elderly cat - 18 - and a year ago she became very thin and couldnt keep anything down. The vet recommended trying Royal Canin Feline Sensitive wet food and it literally saved her life! I immediately started buying it from Pet Drugs online and it brought her back to full health within a month or two and even a year on she's extremely well for 18 and her joints are so much better - she can once again jump up on a chair and tear around like a kitten. To me this proves how much rubbish there is in other cat food products. Pet Drugs online supply high quality foods. I now regularly buy the Royal Canin wet food in packs of 48 from Pet Drugs online who give a fantastic service - speedy delivery and much cheaper than buying from the vet!
