Itrafungol® Oral Solution for Cats

This itraconazole oral solution treats ringworm in cats confirmed by a veterinarian. It targets the fungus on the skin and haircoat to help resolve lesions. With US delivery from Canada, access can be simpler for pet owners without insurance.

What Itrafungol Is and How It Works

This medicine contains itraconazole, a triazole antifungal used in veterinary practice. It inhibits fungal ergosterol synthesis, which weakens the cell membrane and limits replication. The flavored solution supports acceptance and allows precise measurement with the included oral syringe.

Ringworm in cats is commonly caused by Microsporum canis. Treatment typically combines systemic antifungal therapy with environmental cleaning and, when advised, topical measures. Grooming tools, bedding, and surfaces should be cleaned to minimize spore spread.

Who It’s For

Indicated for the treatment of feline dermatophytosis due to Microsporum canis as diagnosed by a veterinarian. The therapy may not be appropriate for pregnant or nursing cats, or for very young or underweight kittens. Itrafungol® oral solution is used once the diagnosis is confirmed and the animal is stable. For broader background on feline pain control options, see Onsior Cat Medicine.

Dosage and Usage

Itrafungol dosage for cats follows a pulse schedule on-label. Veterinarians commonly direct once-daily dosing for one week, followed by one week off, repeated for multiple cycles. Always follow the prescription and label instructions provided for the specific patient.

Shake the bottle before each dose. Use the oral dosing syringe to measure the volume as directed. Administer slowly into the cheek pouch to reduce aspiration risk. Offer food and water as advised by the veterinarian. Rinse the syringe after use and keep it clean between doses. Do not share dosing devices between animals.

If topical adjuncts are recommended, apply them as instructed and avoid contact with open skin or eyes. See supportive antibiotic guidance for mixed conditions in Cephalexin Guide when relevant to secondary infections as directed by a veterinarian.

Strengths and Forms

Itrafungol 10 mg/mL oral solution is supplied with a dosing syringe for accurate measurement. Pack sizes and included accessories can vary by lot and distributor. The flavored liquid is intended for oral use in cats only. Availability may differ by region.

Missed Dose and Timing

If a dose is missed, give it when remembered unless it is close to the next scheduled dose. In that case, skip the missed dose and resume the usual schedule. Do not double the dose. Consistency supports treatment goals; ask the veterinarian if many doses have been missed.

Storage and Travel Basics

Store the bottle at room temperature in a dry place away from direct light. Keep the cap tightly closed and the box out of reach of children and other animals. Do not freeze. During travel, keep the medicine in the original packaging with the prescription label. You can carry a copy of the veterinary prescription and dosing instructions.

Side Effects and Safety

Itrafungol side effects in cats may include vomiting, soft stools or diarrhea, decreased appetite, drooling, lethargy, or weight changes. Some cats may show elevated liver enzymes on monitoring.

Serious reactions are uncommon but can occur. Contact a veterinarian urgently for signs such as persistent vomiting, marked inactivity, jaundice, loss of coordination, or severe skin reactions. Use caution in cats with pre-existing liver disease. The safety of systemic azoles may be limited in very young kittens; veterinarians will assess risk and benefit before prescribing.

Drug Interactions and Cautions

Itraconazole can affect and be affected by other medicines that use hepatic metabolism pathways. Caution is advised with other hepatically cleared drugs. Always disclose all current therapies, including antibiotics, anti-inflammatories, supplements, and topical products. Alcohol-containing topicals near treated areas should be avoided. Do not start or stop medicines without veterinary guidance. Lab monitoring may be recommended in longer courses or when other interacting therapies are present.

What to Expect Over Time

With adherence to the prescribed course and environmental cleaning, lesions may gradually improve and haircoat appearance may normalize. Veterinary rechecks help track clinical progress and guide duration. Cultures or other tests may be used to confirm mycological clearance. Because spores can persist on surfaces, ongoing cleaning and careful handling of grooming tools can reduce re-exposure.

Compare With Alternatives

Systemic options vary by patient and clinician preference. One alternative for some cats is Terbinafine, which may be selected when clinically suitable. Topical adjuncts, such as lime sulfur dips or medicated shampoos, can reduce environmental spore load but are rarely sufficient alone for established cases. Selection depends on culture results, comorbidities, and tolerability.

Availability and Substitutions

Stock can vary by batch and distributor. If the preferred pack is unavailable, a veterinarian may recommend an alternative formulation or a different systemic antifungal. The 52 mL bottle is common, but presentations can change. When substitutions are considered, the prescribing veterinarian should confirm suitability for the patient’s age, weight, and health status.

Patient Suitability and Cost-Saving Tips

Cats with confirmed Microsporum canis infection, stable health status, and no known azole intolerance are typical candidates. Cats with significant liver disease, pregnant or nursing queens, and very small kittens may not be suitable. Multi-month planning can reduce repeat fees and gaps in therapy. Align refills across pet therapies where possible. For example, coordinate with parasite control like Revolution For Cat if refills are due, and review deworming timing in Droncit For Pets. Set calendar reminders to avoid missed doses and missed rechecks.

Questions to Ask Your Clinician

• Confirm the diagnosis: which tests confirm dermatophytosis in this case?
• Describe the dosing plan and expected duration of therapy.
• Ask which monitoring labs, if any, are recommended during treatment.
• Discuss signs that suggest intolerance and when to stop and call.
• Review cleaning steps to reduce environmental contamination at home.
• Clarify any restrictions for pregnant, nursing, or very young cats.
