Tobradex
In brief
- Available from pharmacies and eye‑care clinics; Tobradex is prescribed medicine in most regulated markets, but in practice some pharmacies may supply it without a prescription and online suppliers offer delivery—check local regulations and pharmacy policy.
- Tobradex is used to treat steroid‑responsive ocular inflammation with suspected or confirmed bacterial infection and for post‑surgical prophylaxis; it combines tobramycin (an aminoglycoside antibiotic that inhibits bacterial protein synthesis at the 30S ribosomal subunit) with dexamethasone (a corticosteroid that reduces inflammation via glucocorticoid receptor‑mediated suppression of inflammatory mediators).
- Usual dosage for adults and children ≥2 years is 1–2 drops in the affected eye(s) every 4–6 hours, which may be increased to every 2 hours initially in severe cases; typical course is 5–14 days, with review if treatment extends (up to about 24 days maximum per specialist advice).
- Administered topically as an ophthalmic suspension (eye drops); an ophthalmic ointment formulation is also available in some markets.
- Symptom relief may begin within hours; noticeable clinical improvement is often seen within 24–48 hours, although full resolution can take several days depending on the condition.
- The effect of a single dose generally lasts about 4–6 hours (hence the usual dosing interval); the recommended treatment course is typically 5–14 days depending on the indication.
- There is no specific alcohol interaction with topical Tobradex; alcohol does not alter the effect of the eye drops, though avoid excessive alcohol if you are systemically unwell and follow any additional advice from your clinician.
- The most common side effect is eye irritation (burning, stinging, redness); other effects can include eyelid itching or swelling, increased intraocular pressure with prolonged steroid use, and risk of secondary infection if used long term.

Market Realities And UK Availability
Where Patients Find Tobradex (NHS, Private, Online)
Can I get Tobradex from the NHS or buy it privately?
Genuine Tobradex in the UK is a prescription-only product authorised by the MHRA and supplied by Novartis/Alcon.
Most patients receive Tobradex via an NHS prescription issued by their GP or hospital eye service.
Private ophthalmology clinics and optometry services frequently issue private prescriptions for immediate same-day supply after surgery.
Regulated online pharmacies and some high-street chains such as Boots, LloydsPharmacy and Superdrug dispense Tobradex to a valid prescription, using EPS to speed collection.
Patients report faster access from private clinics and online pharmacies using electronic prescriptions, while NHS repeat systems can add a few days.
Local stock shortages in independent pharmacies occur occasionally, especially after clinic discharges with high demand.
Tobradex typically appears in the UK as a 5 mL dropper bottle with manufacturer packaging and patient information leaflet.
Digital prescription services and the Electronic Prescription Service (EPS) reduce wait times and allow collection from multiple pharmacy chains and independents.

Patient Experiences And Real-World Use Cases
Typical Scenarios And Expectations
Why do patients get prescribed Tobradex?
It is commonly prescribed after eyelid or cataract surgery and for bacterial conjunctivitis with notable inflammation.
Patients usually notice symptomatic relief from irritation and discharge within 24–48 hours when used as directed.
Some people report brief stinging on instillation, which is typically transient and not a reason to stop treatment unless it worsens.
Follow-up appointments are often required when steroids are used, to monitor intraocular pressure if treatment is prolonged.
Typical course lengths are 5–14 days for acute infections and up to 14 days post-operatively unless the prescriber advises otherwise.
Do not share eye drops with others and discard the bottle 28 days after opening to reduce infection risk.
Seek clinical review if symptoms worsen, vision changes, or if there is no improvement within 48–72 hours.
- Onset: Symptom improvement commonly within 24–48 hours.
- Course: 5–14 days typical; up to 14 days post-op.
- Safety note: Attend follow-up if steroids are used beyond a short course.
| Use Case | Typical Timeline |
|---|---|
| Post-operative prophylaxis (e.g. cataract) | Start immediately after surgery; usually up to 14 days |
| Acute bacterial conjunctivitis with inflammation | Symptom relief 24–48 hours; course 5–14 days |

Indications And Who It Suits
Clinical And Practical Suitability
Who is Tobradex appropriate for?
It is indicated for steroid-responsive ocular inflammation where bacterial infection is known or suspected, and for post-surgical prophylaxis.
Adults and children aged 2 years and older typically receive the same topical dosing, while use in children under 2 years is not routinely recommended.
Contact lens wearers should remove lenses before instillation and wait the time advised by their prescriber before reinserting lenses.
Patients with a history of steroid response, glaucoma, or active viral or fungal eye infections are not suitable without specialist advice.
- Adults and children ≥2 years: Usually suitable when indicated.
- Children <2 years: Not routinely recommended; specialist decision only.
- Refer back if history of steroid-induced intraocular pressure rise, or suspected viral/fungal infection.
Practical How-To: Administration And Routines
Step-By-Step Instillation, Missed Dose
How should patients put in the drops and what if they miss one?
- Wash hands and remove contact lenses if worn.
- Tilt the head back and gently pull down the lower eyelid to make a small pocket.
- Hold the dropper above the eye and instil 1–2 drops into the affected eye(s).
- Avoid touching the tip to the eye or eyelid to prevent contamination.
- Close the eye gently for 1–2 minutes and press the inner corner of the eye for a short time to reduce systemic absorption.
- Replace the cap and store as advised.
| Phase | Typical Dosing |
|---|---|
| Initial intensive | Every 2 hours if prescribed |
| Maintenance | 1–2 drops every 4–6 hours |
Missed dose: apply as soon as remembered unless the next dose is due; do not double up.
Accidental overdose from topical use poses low systemic risk; rinse eyes with water if necessary.
Contraindications And Monitoring Requirements
Absolute And Relative Contraindications; Follow-Up
Who must not use Tobradex?
Absolute contraindications include herpetic keratitis, viral conjunctival or corneal infections, fungal eye infections, tuberculous eye disease, active untreated non-bacterial eye infections, and hypersensitivity to tobramycin, dexamethasone or excipients.
Relative contraindications are pre-existing glaucoma, a history of steroid-responsive intraocular pressure rise, and prolonged use due to risks such as secondary infection and cataract formation.
Courses beyond a few weeks require intraocular pressure monitoring and ophthalmology follow-up.
Advise patients to see their prescriber promptly if symptoms suggest a viral or fungal infection, or if vision changes after starting treatment.
Side Effects, Frequency And Escalation
Common Reactions And Emergency Signs
What side effects should patients expect and when is urgent review needed?
Common, usually mild effects include eye discomfort, irritation, transient burning, redness, and occasional eyelid itching or swelling.
With prolonged use there is a risk of secondary infection, raised intraocular pressure and eventual cataract formation.
If severe eye pain, sudden vision loss, intense sensitivity to light, or signs of an allergic reaction occur, stop the drops and seek urgent medical review.
- Common/Mild: Stinging, irritation, redness, eyelid pruritus.
- Serious/Rare: Severe eye pain, sudden visual changes, intense photophobia, signs of hypersensitivity.
If discharge persists or worsens after 48–72 hours of treatment, contact the prescribing clinician for reassessment.
Pharmacology And Clinical Evidence Summary
Mechanism, ATC And Evidence Highlights
How do the components work and what evidence supports use?
Tobramycin is an aminoglycoside antibiotic with bactericidal activity against susceptible Gram-negative and some Gram-positive ocular pathogens.
Dexamethasone is a corticosteroid that suppresses inflammation, reducing pain, swelling and tissue damage.
Combined, they treat and reduce inflammation where bacterial infection is suspected or confirmed and are used for post-operative prophylaxis.
ATC: S01CA01.
| Outcome | Summary |
|---|---|
| Infection Control | Bactericidal activity from tobramycin against susceptible organisms |
| Inflammation Control | Dexamethasone reduces signs and symptoms of inflammation |
Clinical data from manufacturer and regulatory submissions support combined antibiotic/steroid use for post-operative prophylaxis and inflammatory bacterial conjunctivitis, with monitoring for steroid-related adverse events.
Competitors And Alternatives — Clinical And Commercial Comparison
Pros/Cons Versus Maxitrol, Zylet, Others
What are the main alternatives and how do they compare?
Competitor products include Maxitrol (neomycin + polymyxin B + dexamethasone), Zylet (tobramycin + loteprednol), Pred‑G (prednisolone + gentamicin) and Tobradex ST (modified suspension in North America).
Tobradex combines a familiar aminoglycoside antibiotic with dexamethasone and is effective for many bacterial infections with inflammation.
Zylet uses loteprednol, a softer steroid option which may be preferred in steroid responders.
Maxitrol provides a broader antibiotic mix but contains neomycin, which causes sensitivity in some patients.
| Product | Antibiotic | Steroid | Notes |
|---|---|---|---|
| Tobradex | Tobramycin | Dexamethasone | Suitable for many post-op and inflammatory infections |
| Maxitrol | Neomycin + Polymyxin B | Dexamethasone | Broader antibiotic mix; neomycin sensitivity possible |
| Zylet | Tobramycin | Loteprednol | Softer steroid profile; considered for steroid responders |
Choice depends on antibiotic spectrum, steroid potency and patient history such as allergy or steroid sensitivity.
