What Fluconazole is used for
Fluconazole is an important medicine used to treat specific fungal infections that can affect your eyes. It is particularly effective against infections caused by yeasts.
- Candida (yeast) keratitis
- Fungal infection of the eye surface
How it works
Fluconazole belongs to a group of medicines called triazole antifungals. It works by targeting and stopping the growth of certain types of fungi, especially yeasts, that can cause infections in your eye. By doing so, it helps to clear the infection and allows your eye to heal.
How it’s used
Fluconazole can be prescribed in different forms, including eye drops, tablets, or injections, depending on the severity and type of your eye infection. Your doctor will decide the best form and dose for you.
If you are prescribed eye drops, you will typically need to use them 4-6 times a day. For tablets, your doctor will advise you on the specific oral dose and how often to take it. It is crucial to follow your doctor’s instructions precisely for the best outcome.
Always follow your ophthalmologist’s exact instructions.

Please note
Systemic antifungal requiring liver-function monitoring and with many drug interactions. Report any yellowing of the eyes/skin or visual disturbance. Prescription and supervision required.
Precautions & side effects
Fluconazole is a powerful medicine that requires careful use and monitoring. Here are some important precautions:
- Prescription and Supervision: This medicine is a prescription-only drug and must be used under the strict supervision of your doctor.
- Liver Function Monitoring: When taken systemically (as tablets or injections), Fluconazole can affect your liver. Your doctor will likely recommend regular liver function tests to monitor its effects.
- Drug Interactions: Fluconazole can interact with many other medicines. Always inform your doctor about all the medicines you are currently taking, including over-the-counter drugs, supplements, and herbal remedies, to avoid potential interactions.
- Report Side Effects: It is crucial to report any new or worsening symptoms to your doctor immediately. Specifically, watch out for:
- Yellowing of the eyes or skin (jaundice)
- Any new or unusual visual disturbances
These could be signs of serious side effects.
- Effectiveness Against Other Fungi: While effective against yeasts like Candida, Fluconazole is less effective against the filamentous fungi that cause most corneal ulcers in India. Your doctor will determine if this medicine is suitable for your specific type of infection.
Always complete the full course of treatment as prescribed by your doctor, even if your symptoms improve, to ensure the infection is fully cleared and to prevent recurrence.
Understanding Fungal Eye Infections
Fungal eye infections, also known as fungal keratitis, are serious conditions that can affect the cornea, which is the clear, dome-shaped front surface of your eye. These infections can be caused by various types of fungi, including yeasts like Candida. If left untreated, fungal keratitis can lead to significant vision loss or even blindness. Symptoms often include redness, pain, blurred vision, sensitivity to light, and excessive tearing. It’s crucial to seek medical attention promptly if you experience any of these symptoms, especially after an eye injury involving plant material or contact with contaminated water, or if you are a contact lens wearer.
Your doctor will perform a thorough examination and may take a small sample from your eye to identify the exact type of fungus causing the infection. This helps in choosing the most effective medicine, as different antifungals work against different types of fungi. Fluconazole is particularly useful for infections caused by yeasts, such as Candida keratitis. Following your doctor’s advice and completing the full course of treatment are vital for a successful recovery and to prevent the infection from returning.
Correct Use of Eye Drops and General Hygiene
If your doctor prescribes Fluconazole eye drops, proper instillation is key to ensuring the medicine works effectively and to prevent contamination. Always wash your hands thoroughly with soap and water before and after handling eye drops. Tilt your head back slightly and pull down your lower eyelid to create a small pocket. Hold the dropper directly over your eye and squeeze out the prescribed number of drops. Try not to touch the tip of the dropper to your eye or any other surface, as this can contaminate the medicine. Close your eye gently for a minute or two to allow the medicine to be absorbed. If you need to use more than one type of eye drop, wait at least 5-10 minutes between different medications to ensure each drop has enough time to work. Never share your eye drops with anyone else, and always discard any leftover medicine after the prescribed treatment period, even if there’s still some left in the bottle.
Maintaining good eye hygiene is also essential, especially during an infection. Avoid rubbing your eyes, and use clean tissues to gently dab away any discharge. If you wear contact lenses, you must stop wearing them immediately and only resume once your doctor advises it. Always store your eye drops and other eye medicines in a cool, dry place, away from direct sunlight and out of reach of children. Check the expiry date on the packaging and do not use expired medication.
When to Seek Further Medical Help
While Fluconazole is an effective medicine for certain fungal eye infections, it’s important to be aware of when to seek further medical attention. Even if you are diligently using your medication, if your symptoms worsen, or if you develop new symptoms such as increased pain, redness, blurred vision, or discharge, you should contact your doctor immediately. These could be signs that the infection is not responding to the treatment as expected, or that a different issue is developing. If you experience any yellowing of your eyes or skin, or any new visual disturbances while taking Fluconazole tablets or injections, report these to your doctor without delay, as these can be serious side effects requiring immediate attention.
Regular follow-up appointments with your ophthalmologist are crucial to monitor your progress and adjust your treatment if necessary. Do not stop using Fluconazole or change your dosage without consulting your doctor, even if your eye feels better. Stopping treatment too early can lead to the infection returning and becoming harder to treat. Your doctor will guide you on the complete duration of your treatment to ensure a full recovery and protect your vision.
