What Flucloxacillin is used for
Flucloxacillin is an antibiotic medicine that belongs to the Oculoplasty category. It is primarily used to treat infections caused by a specific type of bacteria called Staphylococcus. In the context of eye care, this includes:
- Staphylococcal eyelid infections
- Staphylococcal skin infections around the eye area
These infections can cause discomfort, redness, and swelling. Your ophthalmologist will determine if Flucloxacillin or an equivalent medicine is suitable for your condition.
How it works
Flucloxacillin works as a penicillinase-resistant penicillin. This means it is a type of antibiotic from the penicillin family that is specifically effective against Staphylococcus bacteria, even those that produce an enzyme called penicillinase which can normally inactivate other penicillin antibiotics. By targeting and killing these bacteria, Flucloxacillin helps to clear the infection and relieve symptoms.
How it’s used
Flucloxacillin is typically available in capsule form. The usual dosage for this medicine is 500 mg, taken four times a day. It is very important to follow your ophthalmologist’s instructions precisely regarding the dose and duration of treatment. Do not stop taking the medicine even if your symptoms improve, unless advised by your doctor, as stopping early can lead to the infection returning or becoming harder to treat.
Always take the capsules with a glass of water. If you miss a dose, take it as soon as you remember, unless it is almost time for your next dose. In that case, skip the missed dose and continue with your regular dosing schedule. Do not double the dose to catch up.
Always follow your ophthalmologist’s exact instructions.

Precautions & side effects
When considering Flucloxacillin, it’s important to be aware of certain precautions:
- Prescription Only: This is a prescription eye medicine. It must only be used as directed by a qualified ophthalmologist.
- Indian Equivalents: In India, Cloxacillin or Dicloxacillin are generally considered the usual equivalents for this type of antibiotic. Your doctor will prescribe the most appropriate medicine available and approved in India.

Understanding Eyelid and Skin Infections
Eyelid and skin infections around the eyes are common conditions that can cause discomfort and affect your vision if left untreated. These infections are often caused by bacteria, with Staphylococcus being a frequent culprit. When these bacteria multiply on the eyelids or surrounding skin, they can lead to symptoms such as redness, swelling, tenderness, itching, and sometimes a discharge. Common types of eyelid infections include styes (hordeolum), which are painful red lumps near the edge of the eyelid, and cellulitis, a more widespread bacterial infection of the skin. While these conditions are usually not serious, they require proper medical attention to prevent complications and ensure a speedy recovery. Your ophthalmologist will diagnose the specific type of infection and recommend the most appropriate treatment, which may include antibiotics like Flucloxacillin or its Indian equivalents.
It’s important to understand that while antibiotics are effective against bacterial infections, they do not work against viral or fungal infections. Therefore, an accurate diagnosis by an eye specialist is crucial before starting any treatment. Always complete the full course of antibiotics as prescribed, even if your symptoms improve quickly. Stopping treatment early can allow some bacteria to survive and multiply, leading to a recurrence of the infection or the development of antibiotic resistance, making future treatments more challenging.
General Hygiene and Storage for Eye Medicines
Maintaining good hygiene is paramount when dealing with eye infections and using eye medications. Always wash your hands thoroughly with soap and water before and after touching your eyes or applying any medication. Avoid touching the tip of the medicine bottle or capsule with your fingers or allowing it to touch your eye or any other surface, as this can contaminate the medicine. If you are using eye drops or ointments in addition to oral medication, ensure they are applied correctly. For eye drops, tilt your head back, pull down your lower eyelid to form a pocket, and gently squeeze one drop into the pocket. Close your eye for a few moments without blinking excessively. For eye ointments, place a small ribbon of ointment inside the lower eyelid. Always follow the specific instructions provided by your ophthalmologist or pharmacist for each medication.
Proper storage of your medicines is also essential to maintain their effectiveness and safety. Store all medications in a cool, dry place, away from direct sunlight and moisture, and out of reach of children. Do not store medicines in the bathroom cabinet, as the humidity can affect them. Always check the expiry date on the packaging and discard any expired medications safely. Never share your eye medicines with anyone else, even if they have similar symptoms, as their condition might be different and require a different treatment.
When to Seek Further Medical Help
While antibiotics like Flucloxacillin are effective in treating bacterial eye infections, it’s important to know when to seek further medical attention. If your symptoms do not improve within a few days of starting the medication, or if they worsen, contact your ophthalmologist immediately. Watch out for signs such as increasing pain, severe redness, swelling that spreads, blurred vision, sensitivity to light, or any discharge from the eye. These could indicate a more serious infection or a complication that requires urgent evaluation and possibly a change in treatment.
If you experience any unexpected side effects from the medication, such as an allergic reaction (rash, itching, severe dizziness, trouble breathing), stop the medication and seek immediate medical help. Even if the side effects seem mild, it’s always best to discuss them with your doctor. Remember, your ophthalmologist is your best resource for managing your eye health. Regular follow-up appointments, as advised by your doctor, are crucial to monitor your progress and ensure the infection has completely cleared. Do not hesitate to ask any questions or voice any concerns you may have about your treatment plan.
