1. What is Dexamytrex and what is it used for
Dexamytrex contains two active substances: gentamicin sulfate - an antibiotic from the aminoglycoside group and dexamethasone - 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 intense inflammatory symptoms, and in secondarily infected allergic conjunctivitis and blepharitis.
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 an eye infection caused by viruses (e.g., herpetic keratitis), mycobacteria (e.g., eye tuberculosis), or fungi;
- in the case of corneal ulcers and wounds;
- 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:
- if the patient is using other eye drops or ointments;
- if the patient is using contact lenses. It is not recommended to wear contact lenses while using Dexamytrex;
- if the patient has a disease that causes a decrease in the thickness of the cornea or sclera.
You should contact your doctor immediately if, while using Dexamytrex, you experience:
- partial or complete hearing loss or dizziness;
- an increase in the amount of purulent discharge, inflammation, or pain;
- a sudden, very severe eye and head pain 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;
- blurred vision and difficulty seeing in bright light. These may be symptoms of a disease called cataract;
- if 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 the patient experiences swelling and weight gain, particularly 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 your doctor before the patient decides to discontinue treatment. This risk is particularly important in children and patients treated with ritonavir or cobicistat.
You should 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.
Elderly people
In elderly people, no overall differences in efficacy and safety have been observed compared to younger patients.
Dexamytrex and other medicines
You should tell your doctor about all medicines the patient is currently taking or has recently taken, including those that are available without a prescription.
In particular, you should tell your doctor if the patient is taking: amphotericin B (a medicine used to treat fungal infections), heparin (an anticoagulant), sulfadiazine, cefalotin, and cloxacillin (antibiotics used to treat bacterial infections), 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.
You should tell your doctor about taking ritonavir or cobicistat, as these medicines may increase the dexamethasone content in the blood.
Warning
If Dexamytrex is used with other eye drops or ointments, you should maintain a 15-minute interval between the administration of the medicines, and Dexamytrex should be used last.
Pregnancy, breastfeeding, and fertility
If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor or pharmacist before using this medicine.
Dexamytrex should not be used during pregnancy and breastfeeding, unless the doctor recommends otherwise after a careful assessment of the benefits and risks.
Driving and using machines
Even when used as recommended, Dexamytrex may temporarily blur vision after administration, so you should not drive or operate machinery until the symptoms have completely resolved.
Dexamytrex contains lanolin (wool fat) and butylhydroxytoluene and propylene glycol (Oxynex 2004 components).
Due to the presence of lanolin, the medicine may cause local skin reactions (e.g., contact dermatitis).
Due to the presence of butylhydroxytoluene, the medicine may cause a local skin reaction (e.g., contact dermatitis) or eye and mucous membrane irritation.
The medicine contains 0.275 mg of propylene glycol per 1 g of ointment.
3. How to use Dexamytrex
This medicine should be used as recommended by your doctor. If you have any doubts, you should consult your doctor or pharmacist.
Recommended dose
If not otherwise recommended, apply 5 mm of the ointment to the conjunctival sac of the infected eye 2-3 times a day and before bedtime.
Treatment duration
The treatment duration should not exceed 2 weeks.
Warning! Instructions for administering the medicine:
- 1. Wash your hands thoroughly.
- 2. Unscrew the cap.
- 3. Hold the tube with the nozzle down, using your thumb and index finger.
- 4. Tilt your head back.
- 5. Gently pull down the lower eyelid with your index finger to create a "pocket" between the eyeball and the eyelid, into which the ointment will be inserted.
- 6. Bring the nozzle close to the eye, without touching the nozzle to the eye, eyelid, or surrounding areas.
- 7. Gently squeeze the tube to express the ointment.
- 8. Looking up, insert about 5 mm of ointment into the "pocket".
If the medicine does not get into the eye, repeat the procedure.
- 9. Gently close your eyelid. Do not squeeze your eyelids tightly, as this may push the ointment out of the eye.
- 10. Press the inner corner of your eye at the base of your nose with your finger. This will help minimize the risk of the medicine getting into the entire body.
- 11. If the ointment is to be administered to both eyes, repeat the above steps for the second eye.
- 12. Immediately after using the medicine, screw the cap back on the tube.
Having someone else help you or using a mirror may make it easier to administer the medicine.
Dexamytrex is a sterile medicine. To avoid contamination, do not touch the nozzle with your fingers or touch it to the eye surface or any other surface. Using contaminated ointments can lead to serious vision damage, including vision loss.
If you feel that the effect of Dexamytrex is too strong or too weak, you should consult your doctor or pharmacist.

Using a higher dose of Dexamytrex than recommended
