What Fusidic Acid is used for

Fusidic Acid is an anti-infective medicine, specifically an antibiotic, used to treat certain bacterial infections of the eye. It is particularly effective against infections caused by Staphylococcus bacteria. Your eye doctor may prescribe Fusidic Acid for:

Staphylococcal conjunctivitis: This is an infection of the conjunctiva, the clear membrane that covers the white part of your eye and lines the inside of your eyelids. It often leads to redness, itching, discharge, and a gritty feeling in the eye.
Blepharitis: This condition involves inflammation of the eyelids, often at the base of the eyelashes. It can cause red, itchy, and irritated eyelids, sometimes with crusty deposits.

Due to its convenient dosing schedule, Fusidic Acid is often a suitable choice for treating these conditions in children and elderly patients.

It is crucial to understand that Fusidic Acid is an antibiotic and is only effective against bacterial infections. It will not work for viral or fungal eye infections. Always use this medicine exactly as prescribed by your ophthalmologist.

How it works

Fusidic Acid is a potent antibiotic belonging to the Fusidane class. Its primary action is to stop the growth of bacteria, particularly Staphylococcus species, which are common culprits behind various eye infections. By inhibiting bacterial protein synthesis, it prevents the bacteria from multiplying and spreading, allowing your body’s immune system to clear the infection.

A unique characteristic of Fusidic Acid eye drops or gel is its viscous (thick) formulation. This special gel base is designed to cling to the surface of the eye for a longer period. This extended contact time means the medicine stays in your eye for a greater duration, delivering its therapeutic effect more efficiently. This sustained action is also why it can be effective with less frequent dosing compared to some other eye drops.

By effectively targeting and eliminating the infection-causing bacteria, Fusidic Acid helps to reduce inflammation, redness, discharge, and discomfort associated with conditions like conjunctivitis and blepharitis, promoting healing and restoring eye comfort.

How it’s used

Fusidic Acid eye drops or gel should be used strictly according to your ophthalmologist’s instructions. The typical dosing for this medicine is:

1 drop twice a day only.

It is very important not to exceed this dosage. Using it more frequently will not make it work faster or better and could potentially lead to unnecessary side effects. Your doctor will determine the exact duration of treatment based on your condition and response to the medicine.

Here are general steps on how to properly instil eye drops or apply eye gel:

Wash your hands: Always wash your hands thoroughly with soap and water before touching your eyes or the medicine bottle.
Prepare the bottle: Gently shake the bottle if it’s a suspension, or just open the cap if it’s a gel. Avoid touching the tip of the dropper to any surface, including your eye or fingers, to prevent contamination.
Tilt your head back: Look upwards and gently pull down your lower eyelid with one finger to create a small pocket.
Instil the drop/gel: Hold the bottle upside down directly over your eye. Squeeze the bottle gently to release a single drop into the pocket you created. If it’s a gel, a small ribbon of gel will come out.
Close your eye gently: After instilling the drop or gel, close your eye gently for a minute or two. Avoid blinking excessively or squeezing your eyes shut, as this can push the medicine out.
Wipe excess: If any medicine spills onto your cheek, gently wipe it away with a clean tissue.
Replace the cap: Securely replace the cap on the bottle immediately after use.
Wash hands again: Wash your hands again to remove any medicine residue.

If you are using other eye medicines, wait at least 5-10 minutes between different drops or gels to allow each medicine to be absorbed properly. If you miss a dose, apply 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 double the dose to catch up.

Always follow your ophthalmologist’s exact instructions.

Precautions & side effects

When using Fusidic Acid eye drops or gel, it’s important to be aware of certain precautions and potential effects:

Prescription Medicine: Fusidic Acid is a prescription eye medicine. It must be used only as directed by a qualified ophthalmologist. Do not self-medicate or reuse an old prescription, even if your symptoms seem similar.
Dosing Schedule: The unique formulation of Fusidic Acid allows for a convenient twice-daily dosing. This makes it a particularly useful and manageable option for children and elderly patients who might find more frequent applications challenging. Stick strictly to the prescribed twice-daily schedule.
Temporary Blurring: After instilling Fusidic Acid eye drops or gel, you may experience brief blurring of vision. This is due to the viscous nature of the medicine. It is usually temporary and resolves within a few minutes. Avoid driving or operating machinery until your vision clears completely.
Contact Lenses: If you wear contact lenses, it is generally advised to remove them before applying eye drops or gel and wait at least 15-20 minutes before reinserting them. Your ophthalmologist will provide specific guidance regarding contact lens use during treatment.
Allergies: Inform your doctor if you have any known allergies to Fusidic Acid or any other medications.
Contamination: To prevent contamination, do not touch the tip of the dropper or tube to your eye, eyelid, fingers, or any other surface.
Complete the Course: Even if your symptoms improve, it is crucial to complete the entire course of treatment as prescribed by your doctor. Stopping the medicine too early can lead to the infection returning or becoming more difficult to treat.

Understanding Eye Infections: Conjunctivitis and Blepharitis

Our eyes are delicate organs, and sometimes they can become infected, leading to discomfort and vision problems. Two common bacterial eye infections that Fusidic Acid helps treat are conjunctivitis and blepharitis.

Conjunctivitis, often called ‘pink eye’, is an inflammation of the conjunctiva. This is the thin, clear membrane that covers the white part of your eye and the inside of your eyelids. When bacteria infect this membrane, it can cause symptoms like redness, itching, a gritty feeling, watery eyes, and sometimes a sticky discharge, especially in the morning. It can be quite contagious, so good hygiene is essential to prevent its spread.

Blepharitis is an inflammation of the eyelids, typically affecting the edges where the eyelashes grow. It can make your eyelids red, itchy, swollen, and sometimes crusty, particularly upon waking. Blepharitis can be chronic and may require ongoing management, but antibiotic treatments like Fusidic Acid can help clear up acute bacterial flare-ups.

These infections, while often uncomfortable, are usually treatable with the right medication. Early diagnosis and adherence to your doctor’s prescribed treatment plan are key to a quick recovery and preventing complications.

Correct Application and Hygiene for Eye Medicines

Using eye drops or gels correctly is crucial for their effectiveness and to prevent further infection. Here’s a general guide to ensure you’re applying your medicine safely and effectively:

Always Wash Your Hands: This is the golden rule. Before and after applying eye medicine, thoroughly wash your hands with soap and water. This prevents transferring germs to your eyes or the medicine bottle.
Avoid Contamination: Never let the tip of the dropper or tube touch your eye, eyelid, eyelashes, or any other surface. This can contaminate the medicine, potentially introducing new bacteria into your eye. If the tip does touch something, it’s best to discard that bottle and use a new one.
Proper Instillation: Tilt your head back, look up, and gently pull down your lower eyelid to form a small pocket. Hold the bottle directly over your eye and squeeze out one drop or a small ribbon of gel into this pocket. Close your eye gently for a minute or two to allow the medicine to spread. Avoid blinking vigorously or squeezing your eyes shut.
Wait Between Medicines: If you are prescribed more than one type of eye drop or gel, wait at least 5-10 minutes between each application. This ensures that each medicine has enough time to be absorbed and isn’t washed out by the next one.
Storage: Store your eye medicine as directed on the packaging, usually at room temperature and away from direct sunlight. Do not store it in the bathroom where humidity can be high. Keep it out of reach of children.
Discard After Opening: Eye drops and gels have a limited shelf life once opened, typically 28 days, even if there’s medicine left. Mark the opening date on the bottle and discard it after this period to prevent using contaminated or less effective medicine.

When to Seek Medical Attention

While Fusidic Acid is effective for bacterial eye infections, it’s important to know when to seek further medical advice. Always follow your ophthalmologist’s instructions and attend follow-up appointments. However, if you experience any of the following, contact your doctor immediately:

Worsening Symptoms: If your eye pain, redness, discharge, or blurring of vision gets worse despite using the medicine.
New Symptoms: If you develop new symptoms such as severe headache, nausea, vomiting, or a rash.
No Improvement: If there is no improvement in your symptoms after a few days of using the medicine as prescribed.
Vision Changes: Any sudden or significant changes in your vision, such as severe blurring, double vision, or loss of vision.
Allergic Reaction: Signs of an allergic reaction, such as swelling of the eyelids, face, or throat, severe itching, or difficulty breathing.
