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:
Warnings and precautions
Before starting treatment with Dexamytrex, discuss it with your doctor or pharmacist, especially if:
- you are using other eye drops.
- you are using contact lenses. It is not recommended to use contact lenses during treatment with Dexamytrex.
You should immediately contact your doctor if, during treatment with Dexamytrex:
- you experience partial or complete hearing loss or dizziness;
- the amount of purulent discharge, inflammation or pain increases;
- you experience sudden, severe eye and head pain with accompanying nausea, vomiting, sudden blurred vision, and decreased visual acuity. These may be symptoms of increased pressure in the eyeball;
- you experience blurred vision or other vision disturbances;
- you experience blurred vision and difficulty seeing in bright light. These may be symptoms of a disease called cataract;
- you experience any other eye problems (pain, redness of the eye, tearing, photophobia). These may be symptoms of eye damage.
You should consult your 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 discontinuation of long-term or intensive treatment with Dexamytrex. You should consult your doctor before deciding to discontinue treatment. This risk is particularly important in children and patients treated with ritonavir or cobicistat.
Do not use the medicine 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
Tell your doctor about all the medicines you are taking, or have recently taken, including those obtained without a prescription.
Especially, 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 baby, ask your doctor or pharmacist for advice before using this medicine.
Dexamytrex should not be used during pregnancy and breastfeeding.
Driving and using machines
Even when used as recommended, Dexamytrex may cause temporary blurred vision after administration. Therefore, do not drive or operate machinery 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 during treatment due to calcium accumulation.

3. How to use Dexamytrex
This medicine should always be used exactly as your doctor has instructed. If you are unsure, ask 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.
Treatment should not last longer than 2 weeks.
Warning!
Administration instructions
Before instilling the medicine, 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.
Try to keep your eye open and move it so that the solution is evenly distributed.
Then, gently press the area of the eye corner near the nose with your finger for 2 minutes. This will help limit the absorption of the medicine into the entire body.
Dexamytrex eye drops are sterile. To avoid contamination of the eye drops, do not touch the dropper tip with your fingers or touch it to the eye surface or any other surface. Using contaminated eye drops can lead to serious eye damage, including vision loss.
After using the medicine, replace the protective cap and close the bottle carefully.
If you feel that the effect of Dexamytrex is too strong or too weak, talk to your doctor or pharmacist.
Warning:
If Dexamytrex is used concurrently with other eye drops or ointments, maintain a 15-minute interval 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, overdose is unlikely.

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