1. What is Naclof and what is it used for
Naclof contains diclofenac sodium, a non-steroidal anti-inflammatory drug, which also has analgesic properties.
Indications for use
- Post-operative inflammatory conditions after cataract surgery and other surgical procedures.
- Prophylaxis of cystoid macular edema after cataract surgery with lens implantation.
- Post-traumatic inflammatory conditions in cases of non-perforating eye injuries.
- Inhibition of miosis during cataract surgery.
- Prevention of pain and photophobia symptoms.
2. Important information before using Naclof
When not to use Naclof:
- if the patient is hypersensitive to the active substance or any of the other ingredients of this medicine (listed in section 6);
- if the patient has asthma, urticaria, or nasal polyps after using acetylsalicylic acid. In patients with hypersensitivity to acetylsalicylic acid, cross-sensitivity to phenylacetic acid derivatives and other non-steroidal anti-inflammatory drugs may occur.
Warnings and precautions
Ophthalmic non-steroidal anti-inflammatory drugs may mask the onset and/or development of infections through their action. In case of infection or risk of infection, an appropriate antibacterial agent should be administered simultaneously with Naclof.
Although no such cases have been reported to date, there is a possibility that in patients taking medications that prolong bleeding time or in patients with a history of coagulation disorders, the use of diclofenac may exacerbate coagulation disorders.
Care should be taken when using non-steroidal anti-inflammatory drugs, such as diclofenac, in combination with locally acting steroids (see section Naclof and other medicines).
Naclof is for external use only - locally to the conjunctival sac. It should not be administered by subconjunctival injections or directly into the anterior chamber of the eye.
Naclof contains benzalkonium chloride
The medicine contains 0.0014 mg of benzalkonium chloride in each drop, which corresponds to 0.05 mg/ml.
Contact between the medicine and soft contact lenses should be avoided.
Benzalkonium chloride may be absorbed by soft contact lenses and change their color. Contact lenses should be removed before instillation and not reinserted for at least 15 minutes.
Benzalkonium chloride may also cause eye irritation, especially in people with dry eye syndrome or corneal disorders (the transparent layer at the front of the eye). If abnormal sensations in the eye, stinging, or eye pain occur after using the medicine, the patient should consult a doctor.
Naclof and other medicines
The concomitant use of locally acting non-steroidal anti-inflammatory drugs, such as diclofenac, and locally acting steroids in patients with significant pre-existing corneal infection may increase the risk of complications. Therefore, caution should be exercised.
Naclof has been used safely in clinical trials in combination with antibiotics and beta-blockers.
The patient should inform their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take.
Pregnancy and breastfeeding
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.
In the first six months of pregnancy, Naclof should not be used unless it is necessary and recommended by a doctor. If use is necessary, the smallest dose should be administered for the shortest possible time.
Naclof should not be used during the last three months of pregnancy due to the possibility of premature closure of the fetal ductus arteriosus and potential inhibition of uterine contractions.
After oral administration of diclofenac (e.g., tablets), side effects may occur in the unborn child. It is not known whether the same risk applies to Naclof when used in the eye.
After oral administration of 50 mg of diclofenac (which is equivalent to 10 packages of eye drops), trace amounts of diclofenac were found in breast milk, which should not cause side effects in the child. The use of diclofenac in the eye is not recommended during breastfeeding unless the expected benefits outweigh the potential risk.
Driving and operating machinery
Patients who experience blurred vision after using Naclof should not drive or operate machinery during this time.
3. How to use Naclof
This medicine should always be used as directed by the doctor. In case of doubts, the patient should consult their doctor or pharmacist.
The usual dose of the medicine is:
Adults
- Ophthalmic surgery and its complications: 5 times 1 drop in the 3 hours before surgery. Post-operatively - 3 times 1 drop per day after surgery, and in the following days 1 drop 3 to 5 times a day, for as long as necessary.
- Treatment of pain and photophobia symptoms: 1 drop every 4 to 6 hours. If pain is a result of surgical procedure, 1 to 2 drops are administered 1 hour before the procedure, 1 to 2 drops 15 minutes after the procedure, and 1 drop every 4 to 6 hours for 3 days after surgery.
Elderly patients
No dose adjustment is necessary in elderly patients.
Use in children and adolescents
Naclof is not recommended for use in children. Limited data are available from clinical trials of strabismus surgery in children.
The package contents remain sterile if the original seal is intact. The dropper tip should not be touched to the eye or its surroundings, as this may contaminate the contents of the container.
When using another eye medicine between instillations, a minimum of 5 minutes should be allowed to elapse.
Method of use
- Wash hands before instillation.
- Remove the cap and hold the bottle with the index finger and thumb, without touching the dropper.
- Tilt the head back and direct the dropper tip to the conjunctival sac, without touching it.
- Gently press the bottle to instill 1 drop.
- Gently press the inner corner of the closed eyelid.
- Replace the cap carefully.
Pressure on the lacrimal canal or closure of the eye for 5 minutes after administration may reduce overall absorption. This reduces the risk of side effects and increases local action.
Use of a higher than recommended dose of Naclof
No cases of diclofenac overdose after its use in the form of eye drops have been reported to date.
The risk of overdose, even in the event of accidental ingestion, is virtually non-existent, as the entire 5 ml package contains 5 mg of diclofenac, which is 3% of the recommended daily dose of this medicine in adults when administered orally.
