What Itraconazole is used for
Itraconazole is an anti-infective medicine, specifically an antifungal, used in ophthalmology to treat serious fungal infections affecting the eye and surrounding areas. It is prescribed as an adjunctive oral treatment, meaning it works alongside other treatments, often eye drops, to fight the infection from within your body.
- Fungal Keratitis (a serious fungal infection of the cornea, the clear front part of your eye)
- Fungal Orbital Disease (a fungal infection affecting the tissues and structures around your eye within the eye socket)
How it works
Itraconazole works as a systemic antifungal. This means that when you take the capsule, the medicine is absorbed into your bloodstream and travels throughout your body, reaching the site of the infection in your eye or orbit. It helps to kill the fungi causing the infection or stops them from growing, working in conjunction with other medicines like eye drops that are applied directly to the eye. By tackling the infection systemically, it provides a comprehensive approach to managing these serious fungal conditions.
How it’s used
Itraconazole is available in capsule form, typically in strengths of 100 mg or 200 mg. Your doctor will prescribe the exact dose and frequency based on your specific condition and needs. Generally, the dosing involves taking 100-200 mg once or twice a day. It is very important to take this medicine exactly as prescribed by your ophthalmologist.
To ensure the medicine is absorbed properly by your body, you should always take Itraconazole capsules with food. This helps your body get the most benefit from the medicine. Do not stop taking the medicine even if your symptoms improve, unless specifically advised by your doctor, as stopping early can lead to the infection returning or becoming harder to treat.
Always follow your ophthalmologist’s exact instructions.

- Take with Food: Always take Itraconazole capsules with food. This significantly helps your body absorb the medicine effectively.
- Liver Monitoring: If you are on a long course of Itraconazole, your doctor will likely recommend regular liver function tests. This is because Itraconazole can affect the liver, and monitoring helps ensure your liver remains healthy.
- Report Symptoms Immediately: Itraconazole is a systemic antifungal that requires close supervision. You must report any yellowing of your eyes or skin (jaundice) or any new or worsening visual disturbances to your doctor immediately. These could be signs of serious side effects.
- Drug Interactions: Itraconazole has many potential interactions with other medicines. It is crucial to inform your doctor about all other medications, supplements, and herbal remedies you are currently taking to avoid harmful interactions.
- Prescription and Supervision: This medicine is a prescription-only drug and must be used under the strict supervision of a qualified doctor. Do not self-medicate or share this medicine with others.

Understanding Fungal Eye Infections
Fungal eye infections, such as fungal keratitis or fungal orbital disease, are serious conditions that can affect your vision and overall eye health. Fungal keratitis is an infection of the cornea, the clear, dome-shaped front surface of your eye. It can be caused by various types of fungi and often occurs after an eye injury involving plant material, or in contact lens wearers. Symptoms can include redness, pain, blurred vision, sensitivity to light, and excessive tearing. Fungal orbital disease, on the other hand, affects the tissues and structures around your eyeball within the eye socket. These infections can be quite challenging to treat and require prompt and effective medical intervention to prevent severe complications, including permanent vision loss.
Medicines like Itraconazole play a crucial role in treating these infections, especially when they are severe or widespread. Your doctor will determine the best course of treatment, which often involves a combination of medicines, including eye drops and oral medications like Itraconazole, to target the fungi from different angles. It’s important to understand that treating fungal eye infections can take time, and consistent adherence to your doctor’s instructions is key to a successful outcome.
General Advice for Taking Oral Medications
When taking any oral medication, including Itraconazole capsules, there are some general guidelines that can help ensure you get the most benefit and stay safe. Always take your medicine exactly as prescribed by your doctor. Do not alter the dose, frequency, or duration of treatment without consulting them. If you miss a dose, take it as soon as you remember, unless it’s almost time for your next dose, in which case you should skip the missed dose and continue with your regular schedule. Never take a double dose to make up for a missed one. It’s also a good practice to take your medicine at the same time each day to help you remember. Always keep your medication in its original packaging, stored at room temperature, away from direct sunlight and moisture, and out of reach of children and pets. If you have any questions or concerns about your medication, do not hesitate to ask your doctor or pharmacist.
When to Seek Medical Help
While Itraconazole is an effective medicine for serious fungal eye infections, it’s important to be vigilant for any signs that might indicate a problem or a need for further medical attention. Always attend your scheduled follow-up appointments with your ophthalmologist, as these are crucial for monitoring your progress and adjusting your treatment if necessary. If you experience any new or worsening symptoms related to your eye condition, such as increased pain, redness, blurred vision, or discharge, contact your doctor immediately. Additionally, as Itraconazole can have systemic effects, be aware of general health changes. Specifically, if you notice any yellowing of your skin or the whites of your eyes (jaundice), unusual fatigue, dark urine, pale stools, or any new or unusual visual disturbances, report these to your doctor without delay. These could be signs of a serious side effect requiring immediate medical evaluation. Your health and vision are paramount, so never hesitate to seek professional medical advice if you have any concerns.
