TOBACIN EYE/EAR

# TOBRAMYCIN 0.3% W/V ## SHORT DESCRIPTION **Tobramycin 0.3% W/V** is an **aminoglycoside antibiotic**, commonly formulated as an ophthalmic solution for the treatment of certain **bacterial eye infections**. It works by interfering with bacterial protein production, helping stop the growth of susceptible bacteria. It is intended for bacterial infections and **does not treat viral or fungal eye infections**. --- ## KEY BENEFITS * Helps treat susceptible **bacterial eye infections**. * Works directly against bacteria responsible for infection. * May help reduce symptoms such as eye redness, discharge, irritation, and swelling when these are caused by susceptible bacteria. * Topical ophthalmic administration delivers the medicine directly to the affected eye. * Can be used when prescribed by a healthcare professional. --- ## USES / INDICATIONS Tobramycin 0.3% ophthalmic preparations may be prescribed for susceptible bacterial infections of the eye, including: * **Bacterial conjunctivitis** * Bacterial infections involving the eyelids or surrounding ocular tissues * Other susceptible superficial ocular infections as determined by an eye-care professional ### Important Tobramycin is **not effective against viral or fungal eye infections**. --- ## HOW IT WORKS Tobramycin is an **aminoglycoside antibiotic**. It enters susceptible bacteria and binds to bacterial **30S ribosomal subunits**. This interferes with bacterial protein synthesis and causes production of abnormal proteins, ultimately inhibiting bacterial growth and leading to bacterial cell death. **Tobramycin → interferes with bacterial protein synthesis → inhibits/kills susceptible bacteria → helps resolve bacterial infection.** --- ## DOSAGE & ADMINISTRATION > **Use Tobramycin 0.3% W/V exactly as prescribed by your doctor or eye-care professional.** The dosage and duration depend on the severity and type of infection. ### General Administration for Ophthalmic Preparations * Wash your hands before use. * Do not touch the dropper tip to the eye, eyelids, fingers, or other surfaces. * Instill the prescribed number of drops into the affected eye(s). * Close the eye gently after administration. * Wash your hands after use. * Complete the prescribed course even if symptoms improve, unless your healthcare professional advises otherwise. ### If Using Other Eye Drops If multiple ophthalmic medicines are prescribed, separate their administration by several minutes according to your healthcare professional's instructions. ### Contact Lenses Remove contact lenses before using the eye drops unless your doctor specifically advises otherwise. Follow the product's instructions regarding when lenses can be replaced. ### Missed Dose Use the missed dose when remembered unless it is nearly time for the next dose. **Do not use extra drops to compensate for a missed dose.** --- ## SIDE EFFECTS ### Common Side Effects Temporary effects may include: * Mild eye irritation * Burning or stinging after application * Itching * Redness * Temporary blurred vision * Eye discomfort * Increased tearing These effects are often mild and temporary. ### Serious Side Effects Stop using the medicine and seek medical advice if you develop: * Severe eye pain * Significant swelling * Severe redness * Vision changes that persist * Severe or worsening irritation * Signs of an allergic reaction ### Prolonged Use Prolonged or inappropriate use of topical antibiotics may contribute to **overgrowth of non-susceptible organisms**, including fungi, or contribute to antibiotic resistance. --- ## PRECAUTIONS & WARNINGS ### Allergy Do not use tobramycin if you have previously experienced a serious allergic reaction to **tobramycin or other aminoglycoside antibiotics**. ### For External/Ophthalmic Use If the product is an eye preparation, use it **only in the eye as directed**. Do not swallow or inject it. ### Contact Lens Use Contact lenses may irritate an infected eye and may interfere with treatment. Follow your eye-care professional's instructions regarding lens use. ### Avoid Contamination Do not touch the dropper tip against the eye, eyelashes, fingers, or other surfaces because this can contaminate the medicine. ### Persistent Symptoms If the infection does not improve or becomes worse during treatment, contact your doctor or eye-care professional. ### Prolonged Treatment Long-term or repeated use should be avoided unless medically indicated because it can promote resistant organisms or secondary infections. ### Pregnancy Tell your healthcare professional if you are pregnant or planning pregnancy. Your doctor can determine whether the medicine is appropriate. ### Breastfeeding Discuss use with your healthcare professional if you are breastfeeding. --- ## DRUG INTERACTIONS Because topical ophthalmic tobramycin generally produces lower systemic exposure than oral or injectable aminoglycosides, significant drug interactions are less common. However, inform your doctor about all medicines you use. ### Other Aminoglycosides Using multiple aminoglycoside-containing medicines may increase the risk of aminoglycoside-related adverse effects, particularly if systemic exposure occurs. ### Other Ophthalmic Medicines If you are using multiple eye preparations, your healthcare professional may recommend separating their administration. ### Systemic Medicines Tell your doctor if you are receiving medicines that can affect the kidneys or hearing, particularly systemic aminoglycosides or other potentially nephrotoxic/ototoxic medicines. --- ## STORAGE INFORMATION * Store according to the manufacturer's instructions. * Keep the container tightly closed when not in use. * Protect from excessive heat and direct sunlight. * Keep away from moisture. * Keep out of reach and sight of children. * Do not use after the expiry date. * Do not use if the solution becomes unusually cloudy, discolored, or contaminated. * Do not share eye drops with another person. --- ## PRESCRIPTION STATUS **Prescription Medicine** Tobramycin 0.3% W/V ophthalmic preparations should be used according to the advice of a qualified healthcare professional.
