1. What is Dexamytrex and what is it used for

Dexamytrex contains the active substances: gentamicin sulfate - an antibiotic from the aminoglycoside group and dexamethasone sodium phosphate - a glucocorticosteroid.
The medicine is used in infections of the anterior segment of the eye, caused by microorganisms sensitive to gentamicin, such as bacterial conjunctivitis, keratitis - without corneal epithelial damage and eyelid margin damage with severe inflammatory symptoms, as well as in secondary infected allergic conjunctivitis and eyelid margin inflammation.

2. Important information before using Dexamytrex

When not to use Dexamytrex:

• if the patient is allergic to gentamicin, dexamethasone, or any of the other ingredients of this medicine (listed in section 6);
• if the patient has an acute, purulent disease of the anterior segment of the eye;
• if the patient has superficial, herpetic keratitis or corneal wounds and ulcers;
• if the patient has tuberculosis of the eyeball;
• if the patient has a fungal eye infection;
• if the patient has glaucoma with a narrow and open angle of filtration.

Warnings and precautions

Before starting to use Dexamytrex, you should discuss it with your doctor or pharmacist, especially in the case of:

• if the patient is using other eye drops or ointments;
• if the patient is using contact lenses. It is not recommended to use contact lenses during the use of Dexamytrex.

You should immediately contact your doctor if, during the use of Dexamytrex:

• partial or complete hearing loss or dizziness occurs;
• the amount of purulent discharge, inflammation, or pain increases;
• sudden, very severe eye and head pain occurs with accompanying nausea, vomiting, sudden blurring of vision, and decreased visual acuity. These may be symptoms of increased pressure in the eyeball;
• blurred vision or other vision disturbances occur;
• blurred vision and difficulty seeing in bright light occur. These may be symptoms of a disease called cataract;
• any other eye problems occur (pain, redness of the eye, tearing, photophobia). These may be symptoms of eye damage. You should consult a doctor if you experience swelling and weight gain, especially on the trunk and face, as these are usually the first symptoms of a disease called Cushing's syndrome. Adrenal insufficiency may occur as a result of discontinuing long-term or intensive use of Dexamytrex. You should consult a doctor before deciding to discontinue treatment. This risk is particularly important in children and patients treated with ritonavir or cobicistat. The medicine should not be used for a long time, as gentamicin-resistant bacteria or secondary eye infections (bacterial, fungal, or viral) may develop.

Children and adolescents

The safety and efficacy of Dexamytrex in children have not been established.

Dexamytrex and other medicines

You should tell your doctor about all medicines you are currently taking or have recently taken, including those that are available without a prescription.
Especially, you should tell your doctor if you are using:

• amphotericin B, heparin, sulfadiazine, cefalotin, and cloxacillin, administered topically to the eye. Concurrent administration of Dexamytrex with any of these medicines may lead to the formation of visible precipitates in the conjunctival sac;
• other eye drops or ointments. If Dexamytrex is used concurrently with other eye drops or ointments, a 15-minute interval should be maintained between the administration of the medicines. Eye ointments should always be used last;
• ritonavir or cobicistat, as these medicines may increase the dexamethasone content in the blood.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a child, you should consult your doctor or pharmacist before using this medicine.
Dexamytrex should not be used during pregnancy and breastfeeding.

Driving and using machines

Even when used as recommended, Dexamytrex may temporarily disturb vision after administration, so you should not drive or operate machines until the symptoms have completely resolved.

Dexamytrex contains disodium phosphate dodecahydrate and potassium dihydrogen phosphate

The medicine contains 0.20 mg of phosphates in each drop, which corresponds to 6.52 mg/ml.
In patients with severe damage to the transparent, anterior part of the eye (cornea), phosphates may, in very rare cases, cause corneal clouding due to calcium deposition during treatment.

3. How to use Dexamytrex

This medicine should always be used as directed by your doctor. If you are unsure, you should consult your doctor or pharmacist.
Recommended dose
If not otherwise prescribed, 1 drop into the conjunctival sac of the infected eye 4-6 times a day.
Pull down the lower eyelid and instill 1 drop into the conjunctival sac.
The treatment duration should not exceed 2 weeks.

Warning!

Administration instructions

Before instilling the medicine, you should wash your hands thoroughly.
Tilt your head back and gently pull down the lower eyelid with your index finger. With your other hand, hold the bottle vertically over the eye, without touching the eye, and instill one drop into the conjunctival sac by gently squeezing the bottle wall. You should try to keep your eye open and move it so that the solution is evenly distributed.
Then, you should gently press the area of the eye corner near the nose with your finger for 2 minutes. This can help limit the absorption of the medicine into the entire body.
Dexamytrex eye drops are sterile. To avoid contaminating the eye drops, you should not touch the dropper tip with your fingers or touch the eye surface or any other surface. Using contaminated drops can lead to serious eye damage, including vision loss.
After using the medicine, you should put on the protective cap and carefully close the bottle.
If you feel that the effect of Dexamytrex is too strong or too weak, you should consult your doctor or pharmacist.
Warning:
If Dexamytrex is used concurrently with other eye drops or ointments, a 15-minute interval should be maintained between the administration of the medicines. Eye ointments should always be used last.

Using a higher dose of Dexamytrex than recommended

Since the medicine is used in the eye, you should not expect an overdose.

Missing a dose of Dexamytrex

You should take the missed dose as soon as possible. You should not take a double dose to make up for the missed dose. If you have missed several doses, you should inform your doctor and follow their instructions.
