Itrafungol® Oral Solution for Cats

Itrafungol® is an itraconazole oral solution for veterinary use, prescribed to treat ringworm (dermatophytosis) in cats. With US delivery from Canada, this palatable solution helps clear Microsporum canis infections while avoiding frequent topical dips. Many families purchase it as a cash‑pay option when buying without insurance.

What Itrafungol® Is and How It Works

Itrafungol® contains itraconazole, a triazole antifungal that inhibits ergosterol synthesis in fungal cell membranes. By disrupting membrane integrity, it stops dermatophytes from spreading and allows healthy hair and skin to return. Pulse dosing is commonly used in cats for convenience and to maintain effective levels over time.

Every CanadianInsulin order is prescription‑checked with your clinic and dispensed by a licensed Canadian pharmacy. Orders ship from Canada to the US via prompt, express, cold‑chain shipping. Some customers choose this medicine without insurance to take advantage of Canadian pricing.

Dermatophyte infections shed spores into the environment and onto grooming tools. Systemic therapy with itraconazole reaches hair follicles, making it a useful backbone for ringworm management alongside environmental cleaning and any veterinarian‑recommended topical adjuncts.

Who Itrafungol® Is For

Itrafungol is indicated for cats diagnosed with dermatophytosis caused by Microsporum canis. It is intended for feline use only. Cats that are pregnant or nursing, or those with known hypersensitivity to azoles, should avoid itraconazole unless a veterinarian determines benefits outweigh risks. Use caution in cats with liver disease or significant cardiac conditions. Discuss suitability for very young kittens or underweight cats with a veterinarian before starting therapy.

Households with multiple pets may also consider parasite control to reduce skin irritation confounders and improve overall skin comfort. Explore options under Pet Medications for broader care planning.

Dosage and Usage

Follow the veterinarian’s directions on dose and duration. A widely used regimen for feline ringworm is pulse therapy: an oral dose given once daily for one week, followed by a one‑week break, and repeated for three total treatment weeks. On many labels, the dose is weight‑based at 5 mg/kg per dosing day; the supplied oral syringe is typically calibrated to simplify measuring by body weight. Do not exceed the prescribed amount.

Administration tips:

• Gently shake the bottle if directed by the label.
• Measure the dose with the provided oral syringe; avoid household spoons.
• Administer the solution directly into the cat’s mouth, aiming to the side of the tongue.
• Offer a small treat afterward if permitted by your veterinarian to encourage acceptance.
• Keep consistent daily timing on dosing days throughout each on‑week.

Veterinarians often combine systemic therapy with environmental cleaning and, when appropriate, topical antifungals to reduce spore load on the coat and in the home.

Strengths and Forms

Itrafungol is supplied as a flavored oral solution for cats, commonly published at 10 mg/mL itraconazole, packaged with a dosing syringe. Bottle sizes and packaging may vary by manufacturer batch and market. Availability can differ based on pharmacy stock.

Missed Dose and Timing

If a dose on a treatment day is missed and remembered within a reasonable window, give it then. If it is close to the next scheduled dose, skip the missed dose and resume the regular schedule. Do not double up. For multiple missed doses or uncertainty, contact the prescribing clinic for guidance.

Storage and Travel Basics

Store at controlled room temperature as indicated on the label. Keep the bottle upright, tightly closed, and protected from excessive heat and direct sunlight. Do not freeze. Keep out of reach of children and animals. For travel, keep the bottle in the original carton with the prescription label, pack it in a protective pouch, and carry it with your travel documents. Avoid leaving the medicine in a hot vehicle.

Temperature‑sensitive items ship with cold‑chain handling and insulated packaging.

Benefits

• Systemic treatment reaches hair follicles where dermatophytes reside.
• Pulsed regimen commonly used in cats for practicality.
• Oral solution with flavoring to support acceptance.
• Helps reduce the need for frequent, messy topical dips.
• Supported by veterinary prescribing experience and established antifungal class data.

Side Effects and Safety

Commonly reported effects in cats include:

• Gastrointestinal upset (vomiting, soft stool, decreased appetite)
• Hypersalivation or transient drooling after dosing
• Lethargy or reduced activity
• Occasional skin or coat changes as infections resolve

Less common but more serious risks include elevated liver enzymes or clinical liver injury, significant anorexia with weight loss, or signs that could suggest cardiac intolerance. Contact the prescribing clinic promptly if notable appetite changes, persistent vomiting, jaundice, unusual bruising, or severe lethargy occur. To address nausea when advised by the veterinarian, see our guide on Cerenia Tablets.

Drug Interactions and Cautions

Itraconazole is metabolized by cytochrome P450 enzymes and can interact with other drugs.

• Strong CYP3A4 inhibitors or inducers may raise or lower itraconazole levels.
• Drugs with known QT‑prolongation risk (for example, cisapride) should not be combined due to potential cardiac effects.
• Hepatotoxic drugs given concurrently may increase liver risk; veterinarians may limit combinations or monitor more closely.
• Antacids and potent acid suppressants can affect azole absorption; the impact varies by formulation—ask the prescribing clinic before co‑administration.
• Antibiotics such as macrolides may interact; review all current medicines, including topical, OTC, and supplements. Learn more in Pet Antibiotics Online and the overview on Cephalexin For Dogs.

Never start, stop, or change doses of any medicines without the veterinarian’s guidance.

What to Expect Over Time

Ringworm improvement is typically gradual. As therapy progresses, crusting can lessen, hair re‑growth may begin, and new lesions should decline in number. Environmental cleaning remains important throughout. Some veterinarians monitor by culture or PCR to help confirm clearance. Even after visible improvement, continuation through the prescribed course helps reduce recurrence.

Compare With Alternatives

Other systemic antifungals may be considered based on the cat’s health and infection severity. Terbinafine is sometimes used off‑label in cats for dermatophyte infections under veterinary supervision. Topical adjuncts (antifungal washes or wipes) can help reduce spore load on the coat.

For concurrent parasite control in cats, which can reduce skin confounders and itch from other causes, consider Revolution Plus. This is not an antifungal and does not treat ringworm, but it supports overall dermatologic care in multi‑factor skin cases.

Patient Suitability and Cost‑Saving Tips

• Best for cats diagnosed with dermatophytosis, especially Microsporum canis.
• Use with caution in cats with liver or significant cardiac disease; avoid in pregnancy and lactation unless specifically directed.
• Request a multi‑month prescription if long courses are anticipated; pulse therapy can simplify administration.
• Set reminders for dosing weeks and off‑weeks; schedule refills before starting the next on‑week.
• In multi‑pet homes, coordinate parasite prevention such as Revolution For Puppies for younger pets to support general skin health.
• For GI protection if recommended by your veterinarian, review Sulcrate Suspension Plus.

Questions to Ask Your Clinician

• Is pulse therapy appropriate for this cat, and for how many cycles?
• What monitoring (clinical exams or lab tests) is needed during treatment?
• Which topical or environmental measures should accompany systemic therapy?
• What signs of intolerance should prompt a call to the clinic?
• Could other medicines or supplements interact with itraconazole?
• How long after clinical cure should decontamination continue?
