About Tobradex
Generic Tobradex (Tobramycin, Dexamethasone) combines an aminoglycoside antibiotic with a corticosteroid to treat bacterial eye infections that are accompanied by inflammation. In Australia, the eye-drop formulation (.1 %/.3 % in a bottle) is approved for conditions such as bacterial conjunctivitis, keratitis and post-operative ocular inflammation. By eliminating the causative bacteria while simultaneously reducing swelling, the product helps restore visual comfort and prevents scarring. Some clinicians may prescribe it for off-label situations, for example prophylaxis after intra-ocular surgery, but those uses should only occur under specialist supervision.
What is Generic Tobradex (Tobramycin, Dexamethasone)?
Generic Tobradex (Tobramycin, Dexamethasone) is a combination ophthalmic solution classified as an antibiotic-steroid eye drop. The Therapeutic Goods Administration (TGA) granted registration in 2005, and it is available only by prescription in Australia. Tobramycin targets a broad spectrum of Gram-negative and some Gram-positive bacteria, while dexamethasone suppresses the inflammatory cascade that follows infection or surgical trauma. The product is supplied in sterile, single-dose bottles to maintain sterility and ensure accurate dosing.
How Tobradex Works
Tobramycin binds to the 30 S ribosomal subunit of bacterial cells, disrupting protein synthesis and leading to rapid bacterial death. Dexamethasone, a potent glucocorticoid, penetrates ocular tissues and activates intracellular glucocorticoid receptors. This interaction down-regulates pro-inflammatory cytokines (e.g., IL-1, TNF-α) and inhibits leukocyte migration, reducing edema, pain, and redness. After instillation, the drug reaches therapeutic concentrations within minutes; the antibiotic effect persists for about 4 hours, while the anti-inflammatory action can last up to 6 hours. Metabolism occurs locally; systemic absorption is minimal, and excess drug is cleared via the nasolacrimal duct.
Why Tobradex Is Used for Eye Care Conditions
- Bacterial Conjunctivitis - The antibiotic eradicates common ocular pathogens (e.g., Pseudomonas aeruginosa, Staphylococcus aureus), while dexamethasone curtails the intense hyperemia and discharge that cause patient discomfort. First-line therapy in Australian clinical guidelines often recommends a combination drop when rapid symptom relief is a priority.
- Keratitis - Corneal infections benefit from high-penetration antibiotics; the steroid component mitigates stromal inflammation, preserving corneal clarity and preventing scarring.
- Post-operative Inflammation - After cataract or refractive surgery, inflammation can impair healing. Tobradex provides prophylactic antimicrobial coverage and reduces postoperative swelling, aligning with the Australian Eye Surgeons’ recommendations for short-term steroid use.
- Anterior Uveitis (off-label) - Some ophthalmologists employ the drop to control anterior segment inflammation when topical steroids alone are insufficient, citing case series that show improved control of cellular reaction.
- Blepharitis with secondary infection - The dual action addresses bacterial colonisation of eyelid margins while soothing inflamed lid tissue.
Off-Label and Investigational Uses of Tobradex
Limited case-series and small clinical trials have explored Tobradex for prophylaxis against endophthalmitis following intravitreal injections. Results suggest a reduction in infection rates when used immediately after the procedure, though the TGA has not approved this indication. Off-label use should only be considered under the supervision of a qualified healthcare provider.
Is Tobradex Right for You?
Patients with confirmed bacterial ocular infection and noticeable inflammation are prime candidates. The medication is suitable for adults and older children who can reliably instill drops. Persons with known hypersensitivity to aminoglycosides or corticosteroids, those with uncontrolled glaucoma, or individuals with viral keratitis should avoid it, as dexamethasone may exacerbate intra-ocular pressure or viral replication. Pregnant or breastfeeding women require careful assessment because systemic exposure, though low, is not entirely negligible. Renal impairment does not substantially alter ocular drug handling, but clinicians may monitor serum creatinine in severe cases.
Taking Tobradex Effectively
Instill one drop into the affected eye(s) every 4 hours for the first 48 hours, then reduce to 2-3 times daily as symptoms improve, typically not exceeding 7 days without reassessment. Tilt the head back, pull the lower eyelid down to create a pocket, and avoid touching the bottle tip to the ocular surface. If a dose is missed, apply it as soon as remembered unless the next scheduled dose is less than an hour away-then skip the missed dose. For travel, keep the bottle sealed and store it at room temperature; avoid extreme heat or cold.
Understanding Side Effects and How to Manage Them
- Transient burning or stinging - Common after instillation due to the steroid’s effect on ocular surface cells; a brief pause before blinking usually alleviates discomfort.
- Increased intra-ocular pressure - Dexamethasone can raise pressure in steroid-responsive individuals; patients with glaucoma should have pressure checked before and during treatment. If pressure rises, discontinue the drop and seek ophthalmic review.
- Allergic reaction - Redness, swelling, or pruritus beyond the expected therapeutic effect may indicate hypersensitivity; stop the medication and consult a clinician promptly.
- Superinfection - Prolonged steroid use can permit fungal or opportunistic bacterial overgrowth. Persistent worsening despite therapy warrants re-evaluation and possibly culture-directed treatment.

Frequently Asked Questions
-
How quickly will I notice relief after using Tobradex? Most patients experience a reduction in redness and discharge within 30 minutes to an hour, as the steroid curbs inflammation and the antibiotic begins bacterial eradication.
-
Can I use Tobradex in both eyes simultaneously? Yes, the formulation is safe for bilateral use, provided the dosing interval is maintained for each eye.
-
Is there a risk of cataract formation with short-term use? Short courses (under two weeks) carry minimal cataract risk; prolonged steroid exposure is the primary factor linked to lens opacification.
-
What should I do if I accidentally drop the bottle on a hard surface? Inspect the cap for damage. If the seal appears compromised, discard the bottle and obtain a replacement; contamination could lead to infection.
-
Can I wear contact lenses while on Tobradex? Remove lenses before instillation and wait at least 15 minutes before reinserting to prevent drug absorption onto the lens material.
-
Does Tobradex interact with other eye medications? Concurrent use with other topical antibiotics may be redundant, while combining with additional steroids can amplify intra-ocular pressure effects. Always discuss polypharmacy with an eye-care professional.
-
Why is a prescription required in Australia? The combination of an antibiotic and a potent steroid necessitates professional oversight to avoid misuse, resistance development, and steroid-related complications.
-
Is there a pediatric formulation? The standard bottle is suitable for children over six years who can self-administer; younger patients require caregiver assistance and may benefit from lower-volume dosing devices.
-
How is Tobradex stored after opening? Keep the bottle at room temperature, away from direct sunlight, and discard after 28 days of opening to maintain sterility.
-
Can I use Tobradex for viral conjunctivitis? No; steroids may exacerbate viral replication, and antibiotics provide no benefit against viruses.
Glossary
- Aminoglycoside
- A class of antibiotics that inhibit bacterial protein synthesis by binding to the 30 S ribosomal subunit.
- Glucocorticoid receptor

- The fluid pressure inside the eye; elevated levels can lead to glaucoma if untreated.
- Sterility
- The absence of viable microorganisms; essential for ophthalmic solutions to prevent iatrogenic infection.
