Sporanox Information

medically reviewed by Dr. Bolanle Aina, Pharmacist on February 5, 2026.

Itraconazole at CanadaPharmacyOnline.com

The manufacturer of Sporanox (itraconazole) is Janssen Inc. (a pharmaceutical company of Johnson & Johnson). Initially developed by Janssen, the drug is marketed globally under the same brand name. However, it may be sold under the name Itraspor in specific international markets, such as Turkey. In Canada, Janssen Inc. remains the primary provider of the brand-name formulation. The brand Sporanox is currently unavailable (at this pharmacy).

While the brand-name medication is a staple in antifungal therapy, generic itraconazole is produced by several manufacturers that meet Health Canada's rigorous safety and bioequivalence standards. Common generic producers include Apotex and Sandoz. Generic itraconazole is sourced from manufacturers that meet applicable regulatory standards. However, the specific manufacturer of your dispensed medication may vary based on current pharmacy stock.

Important Information about Generic Itraconazole

Generic itraconazole contains the same active ingredient as brand-name Sporanox. It must meet the same effectiveness and quality standards. This means it is designed to work in the same way as Sporanox. Studies have shown that generic itraconazole is bioequivalent to brand-name Sporanox, meaning it has similar absorption and achieves comparable blood concentrations. However, individual responses to medication can vary due to factors such as metabolism, genetics, and other health conditions.

Dosage:

Itraconazole is available in the following oral strengths and forms:
• Capsules: 100 mg

Your doctor will determine the appropriate dose based on your individual needs and medical conditions.

Usage:

Sporanox is a potent antifungal medication used to treat a wide variety of fungal infections, both systemic (inside the body) and superficial (affecting the skin and nails). It is frequently prescribed for serious internal diseases such as aspergillosis, blastomycosis, and histoplasmosis, which can affect the lungs and spread to other organs. It is an established treatment option for onychomycosis, a persistent fungal infection of the fingernails or toenails. Because Sporanox targets only fungi, it is not effective against viral or bacterial infections, such as the flu. It is critical to note that itraconazole capsules and oral solution are not interchangeable. They are absorbed differently by the body and are used for different types of infections. Never switch between forms without a new prescription and specific dosing instructions.

Mechanism of Action
Itraconazole is a triazole antifungal that disrupts the structural integrity of fungal cell membranes. It targets a specific enzyme called 14-alpha-demethylase, which is essential for converting lanosterol into ergosterol—a vital component of the fungal cell wall. By blocking this enzyme, Sporanox depletes ergosterol while simultaneously leading to an accumulation of toxic methylated sterols within the cell. This biochemical shift makes the fungal cell membrane "leaky" and unstable, preventing the fungus from growing and eventually leading to its death. Because human cells use cholesterol rather than ergosterol, the medication can target the infection with high precision while minimizing its impact on the patient's own cellular structures.

Take Sporanox exactly as your doctor prescribes, following the instructions in the product monograph. Consult your doctor for personalized guidance and safe use. Capsules must be taken immediately after a full meal to ensure proper absorption.

The information below summarizes some, but not all, potential side effects, risks, and interactions. Before starting Sporanox, it is essential to discuss all possible side effects, risks, and interactions with your doctor or pharmacist.

Side Effects:

The information below outlines potential side effects of Sporanox (itraconazole). It is not an exhaustive list, and individual reactions can vary.

Common side effects: These are common side effects of Sporanox; others are possible. Contact your doctor promptly if any side effects are persistent, worsening, or concerning, or if you experience any other concerning symptoms.
• Abnormal taste in the mouth
• Headache or dizziness
• Nausea or stomach upset.
• Rash or itching

• Liver Problems (Hepatotoxicity): Yellowing of the eyes or skin (jaundice), dark urine, pale stools, or severe upper stomach pain.
• Neuropathy: Numbness, tingling, or "pins and needles" in the hands or feet.

Contraindications:

The following is not an exhaustive list of contraindications. Before starting Sporanox, it is crucial to discuss all your medical conditions, past and present, and all medications you are taking with your doctor or pharmacist.

Do not take Sporanox/itraconazole if:
• Allergies: You have a known hypersensitivity to itraconazole or other "azole" antifungals like fluconazole.
• Heart Failure: You have or have ever had congestive heart failure.
• Pregnancy: Except in life-threatening cases, Sporanox should not be used during pregnancy

Tell your doctor about all of your medical conditions, past and present, before starting Sporanox. This is crucial as certain conditions affect the drug's safety.
• Cystic Fibrosis: Patients with this condition may have difficulty effectively absorbing the capsules.
• Liver or Kidney Disease: These organs process the medication, and you may require monitoring or a dose adjustment.
• Low Stomach Acid: Conditions or medications that reduce stomach acid can prevent the capsules from working

Drug Interactions:

Before taking Sporanox, discuss all potential risks and interactions with your doctor or pharmacist. For complete and up-to-date information, please visit the patient information leaflet at https://assets.hpra.ie/products/Human/20752/e8be9fdb-6142-4f81-ad96-dac91dd5371d.pdf.

Provide your doctor with a complete list of all your medications, including prescriptions, over-the-counter (OTC) drugs, vitamins, herbal supplements, recreational drugs, and any significant dietary changes, as these may interact with Sporanox. Sporanox may interact with other medicines, including but not limited to:
• Acid Reducers: Antacids, H2 blockers, and proton pump inhibitors can significantly reduce the absorption of Sporanox capsules.
• Contraindicated Medications: Certain drugs for heart rhythm (e.g., quinidine), cholesterol (e.g., simvastatin), or sedation (e.g., oral midazolam) must not be taken with Sporanox as it can lead to life-threatening reactions.
• Grapefruit Juice: Avoid grapefruit products as they can interfere with how your body processes the drug.

Pregnancy and Breastfeeding:

Sporanox can harm an unborn baby and should not be taken during pregnancy unless the infection is life-threatening. If you are of childbearing age, you must use effective birth control during treatment and for 2 months after your last dose. Itraconazole passes into breast milk. Therefore, breastfeeding is generally discouraged during treatment. Inform your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

Use in Children:

The safety and effectiveness of Sporanox in children under 18 have not been fully established. Use in pediatric patients is limited and must be determined by a specialist.
