Patient leaflet - Nettacin 3 mg / ml eye drops solution in single-dose Container

1. What Nettacin is and what it is used for

Nettacin contains the active substance

netilmicin, an antibiotic that kills bacteria.

It is indicated in adults for the topical

treatment of external infections of the

eye and its surrounding area, caused by

netilmicin sensitive bacteria.

You must talk to a doctor if you do not feel

better or if you feel worse.

2. What you need to know before you use Nettacin

Do not use Nettacin:

  • if you are allergic to netilmicin, any

    aminoglycoside antibiotic (gentamicin,

    tobramycin, kanamycin, etc.) or any of

    the other ingredients of this medicine

    (listed in section 6).

Warnings and precautions

Talk to your doctor or pharmacist before

using Nettacin

If you use antibiotics for a long period of time, you may become more susceptible to eye infections.

Aminoglycoside antibiotics may cause serious hearing problems and kidney problems. If you are using other antibiotic treatment, including oral, with Nettacin, ask your doctor for advice.

Nettacin, is not injectable, therefore it must not be injected into the eye or introduced in the front (anterior chamber) of the eye.

In all the above cases or if you experience allergic reactions with this medicine, discontinue use and consult your doctor.

Children and adolescents

The safety and efficacy of Nettacin, in children or adolescents have not been established.

Nettacin can be used with other medicines for ophthalmic use, but it is important to follow the instructions in section 3. Tell your doctor or pharmacist if you are taking:

  • any other antibiotic, in particular

    polymyxin B, colistin, viomycin, streptomycin, vancomycin or cephaloridine. The simultaneous use of Nettacin, with other aminoglycoside antibiotics could increase the risk of kidney problems, hearing problems, or it may affect how well the other antibiotics work;

  • cisplatin (used in anti-cancer therapy);
  • diuretics (medicines that reduce water

    retention) as ethacrynic acid and furosemide.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.

Pregnancy

This medicine should be used only if considered appropriate by your doctor.

Breast-feeding

Nettacin is not recommended for use during breast-feeding as this medicine is excreted into breast milk in small amounts.

Driving and using machines

You may experience temporary blurred vision after using Nettacin. Do not drive or operate machinery until your vision is clear again.

3. How to use Nettacin

Always use this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

The recommended dose is 1 or 2 drops into the affected eye 3 times daily, or as directed by your doctor.

If you wear contact lenses

Contact lens wear is not recommended during treatment of a superficial ocular infection.

If you need to wear contact lenses, you can use Nettacin in single-dose containers because it does not contain preservatives.

Instructions for use

  1. 1)

    Wash/cleanse your hands thoroughly

    before putting in the eye drops.

  2. 2)

    Open the aluminium sachet containing

    the single-dose containers.

  3. 3)

    Make sure the single-dose container is

    intact.

  4. 4)

    Detach the single-dose container

    from the strip and put the unopened containers back into the sachet.

  5. 5)

    Open by turning the flap of the unit

    without pulling.

  6. 6)

    Do not touch the tip after opening the

    container.

  7. 7)

    Squeeze the single-dose container

    gently so that a single drop falls into the affected eye(s). Do not allow the tip of the single-dose container to touch the eye or eyelids, or any other surface, so to avoid possible contamination.

Keep the affected eye closed and press your fingertip against the inside corner of the closed eye, and hold for 1 minute. This is important because it reduces the amount of drug that goes into the rest of your body.

If you use more Nettacin than you should

No cases of overdose have ever been reported with the use of Nettacin. If you unintentionally instill more drops than you should, you are unlikely to have any problems. Apply the next dose as usual.

If you forget to use Nettacin

Do not use a double dose to make up for a forgotten dose.

If you stop using Nettacin

If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
