If too much TobraDex ophthalmic suspension gets into your eye, rinse it out with lukewarm water. Do not apply any more drops until the next scheduled use.
To supplement treatment with TobraDex ophthalmic suspension, your doctor may prescribe TobraDex ophthalmic ointment (which is best used in the evening, before bedtime).
Children and adolescents

Precautions
- If you develop an allergic reaction such as itching of the eyes, swelling of the eyelids, redness of the eyes, or even generalised reactions such as redness of the skin, itching, papules on the skin, anaphylaxis and blisters on the skin, stop the treatment and consult your doctor. These allergic reactions may also occur during other treatments (topical or systemic) with the same type of antibiotic (aminoglycoside). If you are taking other antibiotics at the same time as TobraDex ophthalmic suspension, ask your doctor for advice.
- If you suffer or have previously suffered from a disease such as myasthenia gravis or Parkinson's disease, ask your doctor for advice. Antibiotics of this type may cause muscle weakness to worsen.
- Prolonged use of TobraDex ophthalmic suspension may cause fungal infections.
- In the presence of a purulent eye infection.
- Corticosteroids may mask, activate or aggravate an eye infection. TobraDex ophthalmic suspension may delay healing if used for a prolonged period. It may also cause an increase in intraocular pressure, leading to glaucoma. During treatment with TobraDex ophthalmic suspension, always remain under medical supervision and have your intraocular pressure measured regularly by your doctor.
- If the problems treated with TobraDex ophthalmic suspension worsen after 2-3 days of treatment or if new symptoms appear, consult your doctor immediately.
- If you suffer from diseases causing thinning of the tissues of the eye (cornea or sclera), local application of corticosteroids may cause perforation of the eye.
- If you are diabetic (particularly type I), there is a risk of cataract. The use of corticosteroids in diabetics increases the risk of early and rapidly progressive cataracts.
- If you develop swelling of the trunk and face (Cushing's syndrome), tell your doctor. This risk is particularly high in children or patients taking ritonavir or cobicistat.
- TobraDex ophthalmic suspension contains benzalkonium chloride, a preservative that can irritate the eyes and discolour soft contact lenses. Avoid contact with soft contact lenses. During treatment with TobraDex ophthalmic suspension, wait at least 15 minutes after application before reinserting your lenses.
- Benzalkonium chloride may also cause irritation to the eye, particularly in cases of dry eye or corneal disease (transparent layer on the front of the eye). Please consult your doctor if you experience any unusual sensation, burning or pain in the eye after using this medicine.
- Caution should be exercised when TobraDex ophthalmic suspension is used at the same time as a mydriatic (a medicine designed to dilate the pupil), as an increase in intraocular pressure cannot be ruled out with this combination.
- The use and safety of TobraDex ophthalmic suspension in children and adolescents have not yet been studied. Consequently, the use of TobraDex ophthalmic suspension is not recommended in children and adolescents.
- If several eye preparations are used, there should be an interval of at least 5 minutes between each administration. Eye ointments should be used last.
- Please inform your doctor or pharmacist if you are suffering from any other illnesses, if you are allergic or if you are already taking other medicines (even if you are self-medicating!)/you are taking or already use other medicines for internal or ocular use.
- As sight may be temporarily impaired after instilling TobraDex ophthalmic suspension, it is recommended that you wait until the symptom has disappeared before driving a vehicle or operating machinery.

What else do you need to consider?
It is essential that your doctor check your eyes regularly throughout treatment with TobraDex ophthalmic suspension.
The antibiotic (tobramycin) contained in this medicine is not effective against all the micro-organisms that cause eye infections. Using the wrong antibiotic or the wrong dose can lead to complications. For this reason, never use this medicine without a doctor's prescription for the treatment of an illness other than the one you are suffering from, or for other people. In the event of a new infection occurring at a later date, do not use the ophthalmic suspension without consulting your doctor again.

TobraDex ophthalmic suspension should not be used during pregnancy.
TobraDex ophthalmic suspension should not be used during breast-feeding. You should therefore either stop breast-feeding or discontinue treatment.
