It is used during certain eye surgeries and after surgeries:

  • prevention of miosis ( pupil contraction ) during cataract surgery
  • prevention of inflammation after cataract surgery and after surgery on the front of the eye 
  • treatment of eye pain in photorefractive keratectomy (surgery for refractive errors such as myopia) up to 24 hours after surgery

Diclofenac sodium found in Dicloabak may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.

2. What you need to know before using Dicloabak

Do not use Dicloabak

  • if you are allergic (hypersensitive) to diclofenac sodium or any of the other ingredients of this medicine (listed in section 6).
  • if you have had allergies, urticaria (itchy hives ), acute runny nose, swelling and irritation of the nose, or asthma, started with the use of these eye drops or a similar medicine, such as anti-inflammatory painkillers or acetylsalicylic acid.

Warnings and cautions

Talk to your doctor, pharmacist, or nurse before using Dicloabak. You should use this medicine with caution:

  • Dicloabac, like other anti-inflammatory painkillers, can in rare cases cause anaphylactic reactions (severe allergic reactions that cause difficulty breathing and dizziness), even without prior use of the medicine.
  • You should stop treatment and contact your doctor or emergency department in case of hypersensitivity reactions or symptoms suggestive of allergy to this medicine, especially if you have asthma attacks or sudden swelling of the face and neck.
  • Before using this medicine, tell your doctor if you have asthma in combination with a chronic runny nose, chronic sinusitis, and/or nasal polyps.
  • An acute eye infection can be obscured by topical use of anti-inflammatory painkillers. Anti-inflammatory painkillers lack bactericidal properties. If an eye infection occurs, caution should be exercised when using these medicines in combination with one or more bactericidal medicines.
  • Concomitant use in the eye of anti-inflammatory painkillers and steroids (eg dexamethasone) may increase the risk of delayed healing.
  • Anti-inflammatory painkillers can delay the healing of the cornea.
  • If you tend to bleed or if you are being treated with anticoagulants(medicines that thin the blood).
  • The use of topical anti-inflammatory painkillers in high doses and for a long time can lead to corneal inflammation.
  • The risk of side effects affecting the cornea may increase in patients who have had repeated eye surgeries within a short period of time, have diabetes, a disease that affects the surface of the eye (eg chronically dry eyes), rheumatoid arthritis.
  • The use of contact lenses is not recommended immediately after cataract surgery. Consult your doctor when you can wear contact lenses again.

If your symptoms get worse or not get better, you need to see a doctor.
