What is Isaderm® Gel?

Isaderm® Gel is a topical veterinary medication for treating certain skin conditions in dogs such as superficial pyoderma, acute moist dermatitis, commonly known as hot spots, and skin fold dermatitis.

How does it work?

Isaderm® Gel comprises two active ingredients:

Fusidic Acid: An antibacterial agent effective against various bacteria, particularly Staphylococcus species. This ingredient works by disrupting bacterial protein synthesis.

Betamethasone: This ingredient is a corticosteroid with anti-inflammatory and antipruritic properties to alleviate symptoms of inflammation and itching.

Dose and Administration

Apply as directed by your veterinarian. If advised by your vet, clean the affected area and pat dry prior to application of the gel.

Apply the prescribed amount of gel directly to the affected area and spread it evenly. Gently massage the gel into the skin. Prevent your pet from licking the treated area for at least 30 minutes. Wash your hands after applying the gel. It is recommended to wear gloves to prevent absorption through your skin. Observe your pet for any adverse reactions and report concerns to your vet. Complete the full course of treatment as prescribed.

Contraindications and Precautions

Allergy to Active Ingredients: Do not use in pets with a known hypersensitivity to the active ingredients (such as fusidic acid or betamethasone) or to any of the excipients in the product.

Fungal Skin Infections: Not suitable for areas affected by fungal infections unless co-administration with appropriate antifungal therapy is underway.

Parasitic Skin Infections: Ineffective on skin areas with parasitic infestations, such as mange, without concurrent appropriate parasiticidal therapy.

Ulcerative Conditions: Contraindicated in pets with ulcerative conditions due to the potential for delayed wound healing.

Pregnancy and Lactation: The safety of Isaderm Gel in pregnant or lactating animals has not been established. Use only under the guidance of a veterinarian.

Very Young Animals: The safety and efficacy have not been established in very young pets. Consult your veterinarian for use in puppies or kittens

Large Areas of Damage: Avoid use on extensive areas of damaged skin.

Potential Side Effects

Isaderm Gel can have side effects such as irritation, redness, itching, and delayed wound healing. It can also cause systemic effects, gastrointestinal issues, increased licking, and allergic reactions. These side effects are rare, but it's important to seek veterinary guidance if you notice any unusual symptoms in your pet.

Storage

Store in a cool dry place, making sure not to refrigerate or freeze. Keep out of reach of children and pets.
