What Voriconazole (oral) is used for
Voriconazole (oral) is a powerful antifungal medicine used to treat serious fungal infections that affect your eyes and the areas around them. These infections can be quite severe and require strong medication to prevent further damage and help you recover.
- Severe fungal keratitis (a serious fungal infection of the cornea, the clear front part of your eye)
- Fungal endophthalmitis (a serious fungal infection inside the eye)
- Fungal orbital infection (a fungal infection affecting the tissues around your eyeball, within the eye socket)
Your doctor will determine if Voriconazole (oral) is the right treatment for your specific condition based on the type and severity of your fungal infection.
How it works
Voriconazole (oral) works by being absorbed into your bloodstream after you take it by mouth. Once in your blood, it travels throughout your body, including to your eyes, to fight the fungal infection directly. It belongs to a group of medicines called triazole antifungals, which target and kill the fungi causing the infection. By reaching the site of infection through your bloodstream, it can effectively combat deep-seated fungal infections that might be difficult to treat with topical medicines alone.
How it’s used
Voriconazole (oral) is taken by mouth, usually in tablet form. The typical dose is 200 mg twice a day. However, it is very important to remember that your doctor will adjust your specific dose based on factors like your body weight and how well your liver is functioning. Always follow your doctor’s instructions precisely regarding the dose, frequency, and duration of your treatment. Do not stop taking this medicine or change your dose without consulting your doctor, even if you start to feel better. Completing the full course of treatment is crucial to ensure the infection is fully cleared and to prevent it from returning.
Always follow your ophthalmologist’s exact instructions.

Understanding Fungal Eye Infections
Fungal eye infections, like those treated by Voriconazole (oral), can be serious and require prompt and effective treatment. These infections occur when fungi, which are common in our environment, enter the eye. This can happen due to an eye injury, contact lens contamination, or sometimes without a clear reason. Symptoms can vary but often include redness, pain, blurred vision, discharge, and sensitivity to light. If left untreated, fungal eye infections can lead to significant vision loss or even loss of the eye. That’s why it’s so important to see an ophthalmologist (eye doctor) immediately if you suspect an eye infection. Your doctor will perform tests to identify the type of infection and prescribe the most appropriate treatment, which in severe cases, may include oral antifungal medicines like Voriconazole.
While Voriconazole (oral) works from the inside out, it’s also important to maintain good eye hygiene to prevent further irritation or secondary infections. Always wash your hands thoroughly with soap and water before touching your eyes or any eye medication. Avoid rubbing your eyes, especially if they are irritated or infected. If you wear contact lenses, your doctor will likely advise you to stop wearing them during the treatment period and provide guidance on when it’s safe to resume. Always follow your doctor’s specific instructions for eye care during your treatment.
General Advice for Taking Oral Medications
Taking oral medications correctly is key to their effectiveness. Always take your Voriconazole (oral) tablets exactly as prescribed by your doctor. This usually means taking them at specific times each day, which helps maintain a steady level of the medicine in your body. If you miss a dose, take it as soon as you remember, unless it’s almost time for your next dose. In that case, skip the missed dose and continue with your regular schedule. Do not take a double dose to make up for a missed one. It’s also important to swallow the tablets whole with water; do not crush, chew, or break them unless specifically instructed by your doctor or pharmacist. Always store your medicine in a cool, dry place, away from direct sunlight and out of reach of children. Do not store it in the bathroom, as humidity can affect the medicine.
During your treatment with Voriconazole (oral), you will have regular follow-up appointments with your doctor. These appointments are crucial for monitoring your progress, checking for any side effects, and performing necessary tests like liver function monitoring. It’s important to attend all your scheduled appointments and communicate openly with your doctor about how you are feeling and any concerns you may have. Even if your symptoms improve, do not stop taking the medicine without your doctor’s approval, as stopping too early can lead to the infection returning or becoming harder to treat. Your doctor will guide you on the appropriate duration of treatment to ensure the infection is fully eradicated.
When to Seek Medical Help
While Voriconazole (oral) is an effective medicine, it’s important to be aware of potential side effects and when to seek immediate medical attention. As mentioned, this medicine can cause temporary visual disturbances and light sensitivity. If these symptoms are severe, persistent, or significantly impact your daily activities, inform your doctor. More seriously, you must report any yellowing of your eyes or skin (jaundice) to your doctor right away, as this can be a sign of liver problems. Also, if you experience any new or worsening symptoms related to your eye infection, such as increased pain, redness, discharge, or a sudden decrease in vision, contact your ophthalmologist immediately. If you develop a rash, severe dizziness, difficulty breathing, or any other severe or unusual symptoms, seek emergency medical help. Always remember that your healthcare team at Pristine Eye Hospitals is here to support you throughout your treatment journey. Do not hesitate to reach out if you have any questions or concerns about your medication or your eye health.
