Therapeutic class: Ophthalmic corticosteroid and aminoglycoside antibiotic combination

What is Cotadex used for?

Cotadex 100 mg + 300 mg/100 ml eye drops by Monicopharma Limited is an eye medicine containing Dexamethasone + Tobramycin.

What is Cotadex?

Cotadex 100 mg + 300 mg/100 ml eye drops by Monicopharma Limited is an eye medicine containing Dexamethasone + Tobramycin. In Bangladesh, it is mainly used for steroid-responsive eye inflammation where a bacterial eye infection is present or there is a significant risk of bacterial infection.

Dexamethasone + Tobramycin combines dexamethasone, which reduces inflammation, redness and swelling, with tobramycin, an aminoglycoside antibiotic that kills susceptible bacteria. A key caution is that steroid-containing eye medicines can worsen viral, fungal or untreated eye infections and may raise eye pressure with prolonged use.

Indications

  • Steroid-responsive inflammatory conditions of the eye where superficial bacterial infection is present or suspected.
  • Inflammation of the eyelids, conjunctiva, cornea or anterior part of the eye when susceptible bacteria are involved or prophylactic antibiotic cover is considered necessary.
  • Post-operative ocular inflammation when bacterial infection risk is considered by the prescriber.

Dosage & Administration

Use only as prescribed for the specific eye condition. For adults, eye drops are commonly instilled into the affected eye at intervals directed by the doctor, and frequency may be higher at the start and then reduced as the condition improves. Eye ointment is usually applied as a small ribbon inside the lower eyelid as directed. Do not touch the dropper or tube tip to the eye, eyelid or any surface. If using more than one eye medicine, leave a gap between products; ointment is usually applied last. Complete the prescribed course and do not continue longer than advised.

Side Effects

  • Temporary burning, stinging, irritation, itching or discomfort after application.
  • Blurred vision, especially after ointment use.
  • Redness, tearing, eyelid swelling or foreign-body sensation.
  • Allergic reactions such as rash, worsening itching or swelling.
  • Raised intraocular pressure or glaucoma with prolonged steroid use.
  • Cataract formation with long-term steroid exposure.
  • Delayed wound healing or corneal thinning in susceptible patients.
  • Secondary eye infection, including fungal infection, may occur with prolonged use.
  • Seek urgent medical help for eye pain, worsening redness, vision changes, severe swelling or signs of allergy.

Precautions & Warnings

Use with caution in people with glaucoma, high eye pressure, history of herpes simplex eye disease, corneal thinning, recent eye surgery, diabetes, or suspected fungal, viral or mycobacterial eye infection. Prolonged use may require monitoring of intraocular pressure and examination for secondary infection. Do not wear contact lenses during active eye infection unless the prescriber advises otherwise. Use under the guidance of a registered doctor or pharmacist.

Drug Interactions

  • Other eye drops or ointments may dilute or interfere with each other; separate applications by an appropriate interval as advised, and use ointment last.
  • Concomitant use with other corticosteroid eye medicines may increase the risk of raised eye pressure, cataract or delayed healing.
  • Topical non-steroidal anti-inflammatory eye medicines used after eye surgery may increase the risk of corneal healing problems when combined with corticosteroids.
  • Systemic absorption from eye use is usually low, but tell the doctor if using aminoglycoside antibiotics or medicines associated with kidney or hearing toxicity.

Contraindications

  • Hypersensitivity to dexamethasone, tobramycin, other aminoglycosides, or any component of the product.
  • Herpes simplex epithelial keratitis, vaccinia, varicella or other viral diseases of the cornea and conjunctiva.
  • Fungal diseases of the eye.
  • Mycobacterial infection of the eye.
  • Untreated purulent eye infection where steroid use may mask or worsen infection.

Pregnancy & Lactation

During pregnancy or breastfeeding, use only if the expected benefit justifies the potential risk and only on medical advice. Systemic exposure from ophthalmic use is generally low, but steroid and aminoglycoside exposure should still be minimised. After applying drops, gently pressing the inner corner of the eye for a short time may reduce systemic absorption.

Storage Conditions

Store at room temperature away from excessive heat, moisture and direct light. Keep the bottle or tube tightly closed and out of the reach of children. Do not use if the solution changes colour, becomes cloudy, the seal is broken, or the expiry date has passed. Discard after the period recommended on the label or by the pharmacist after opening.

Frequently Asked Questions

Can I use Cotadex for any red or itchy eye?

No. Cotadex contains a steroid and an antibiotic, so it should be used only when prescribed for a suitable eye condition. Steroids can worsen viral, fungal or untreated infections.

What should I do if my vision becomes blurred after using Cotadex?

Temporary blurred vision can occur, especially with ointment. Do not drive or operate machinery until vision is clear. If blurring persists or vision worsens, contact a doctor promptly.

Can I wear contact lenses while using Cotadex?

Do not wear contact lenses during an active eye infection unless your prescriber specifically advises it. Ask your doctor when it is safe to start wearing lenses again.

How long should I continue Cotadex?

Use Cotadex for the duration prescribed. Do not stop early or continue longer without medical advice, because prolonged steroid use may raise eye pressure and increase infection risk.
