1. What NETDEX is and what it is used for

NETDEX contains two medicines: netilmicin and dexamethasone.

  • Netilmicin is an antibiotic that kills bacteria.
  • Dexamethasone is a corticosteroid that reduces inflammation.

Antibiotics are used to treat bacterial infections and are not effective against viral infections.

It is important that you follow the instructions regarding dosage, administration interval, and treatment duration as indicated by your doctor.

Do not store or reuse this medicine. If you have any leftover antibiotic after completing treatment, return it to the pharmacy for proper disposal. Do not throw medicines down the drain or in the trash.

NETDEX is used in adults to reduce inflammation and to kill bacteria in the eyes that are swollen, irritated, and likely to be infected with bacteria.

You should consult a doctor if your condition worsens or does not improve at the end of treatment.

2. What you need to know before you use NETDEX

Netilmicin/dexamethasone can be used in adults, including the elderly.

It is not recommended for people under 18 years of age.

Do not use NETDEX:

  • If you are allergic to netilmicin, dexamethasone, antibiotics known as aminoglycoside antibiotics (such as tobramycin, kanamycin, amikacin, gentamicin, etc.) or to any of the other components of this medicine (listed in section 6).
  • If your doctor has told you that your eye pressure is too high.
  • If you think you may have a viral or fungal infection in or around the eye.
  • If you have now, or have had in the past, a viral eye infection caused by the herpes simplex virus (HSV).
  • If your doctor has warned you that you have an eye infection caused by bacteria known as mycobacteria.

Warnings and precautions

Consult your doctor or pharmacist before starting to use NETDEX.

Consult your doctor if you experience swelling and weight gain around the trunk and in the face, as these are usually the first signs of a syndrome called Cushing's syndrome. Suppression of adrenal gland function may occur after intensive or long-term treatment with netilmicin/dexamethasone. Consult your doctor before stopping treatment on your own. These risks are especially important in children and patients treated with a medicine called ritonavir or cobicistat.

Contact your doctor if you experience blurred vision or other visual disturbances.

If you use NETDEX for a long time

  • Eye pressure may increase and cause damage to the nerves of the eye, leading to vision problems. If you use netilmicin/dexamethasone for more than 15 days, your doctor should check your eye pressure regularly;
  • You may develop cataracts;
  • Wounds may take longer to heal;
  • Your body may not defend itself against other types of eye infections as well as it should, such as fungal or viral infections;
  • Eye infections that produce a lot of pus, with the use of corticosteroids, may worsen or it may be more difficult to identify the type of bacteria that cause the infection;
  • The corticosteroid in netilmicin/dexamethasone may cause the surfaces of the eye to narrow and even perforate;
  • You may start to become allergic to the antibiotic in the eye drops.

Before usingNETDEX, tell your doctor if:

  • You have glaucoma or a family history of glaucoma;
  • You have corneal problems;
  • You are taking other medicines that contain phosphates. Your doctor will monitor your cornea at regular intervals;
  • You wear contact lenses. You can continue to use netilmicin/dexamentasona, but you must follow the instructions for use with contact lenses in section 3.

Children and adolescents

NETDEX is not recommended for use in children or adolescents (from birth to 18 years of age).

For external use only

Use NETDEX only on the surface of the eye. This medicine should not be injected or swallowed.

Using NETDEX with other medicines

NETDEX may interact with other medicines. Tell your doctor or pharmacist if you are using, have recently used, or might use any eye product or any other medicine, including those obtained without a prescription. You can use netilmicin/dexamethasone with other eye products, but you must follow the instructions in section 3.

Especially, tell your doctor or pharmacist if you are taking:

  • Any other antibiotic, in particular polymyxin B, colistin, viomycin, streptomycin, vancomycin, or cefaloridine. The simultaneous use of netilmicin/dexamethasone with other antibiotics may increase the risk of kidney problems, hearing problems, or may affect the proper functioning of the other antibiotics;
  • Cisplatin (an anticancer medicine);
  • Diuretics (medicines that reduce fluid retention) such as etacrynic acid and furosemide;
  • Anticholinergic medicines (medicines that stop gland secretion) such as atropine;
  • Ritonavir or cobicistat, as these may increase the amount of dexamethasone in the blood;
  • Other medicines that contain phosphates. Your doctor will monitor your cornea at regular intervals.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.

Use during pregnancy

It is preferable not to use NETDEX during pregnancy unless your doctor considers it necessary.

Use during breastfeeding

NETDEX should not be used if you are breastfeeding.

Driving and using machines

When using NETDEX, your vision may become blurred for a short time. If this happens, do not drive or use machines until your vision clears.

NETDEX containsbenzalkonium chloride and phosphates

This medicine contains 0.05 mg of benzalkonium chloride in each ml.

Benzalkonium chloride can be absorbed by soft contact lenses, altering their color. Remove contact lenses before using this medicine and wait 15 minutes before putting them back.

Benzalkonium chloride may cause eye irritation, especially if you have dry eye or other corneal diseases (the transparent layer at the front of the eye). Consult your doctor if you feel any unusual sensation, itching, or pain in the eye after using this medicine.

This medicine contains 0.18 mg of phosphates in each drop, equivalent to 3.66 mg/ml.

If you have severe damage to the transparent layer at the front of the eye (the cornea), treatment with phosphates, in very rare cases, may cause blurred vision due to calcium accumulation.
