The safe use of Catalin for the treatment of senile cataracts requires special attention to dosage control, medication for special populations, and operating procedures. The following are specific precautions:

1. Recommended dosage

3-4 times a day, 1-2 drops each time. The medication interval should be evenly distributed, and it is recommended to use it at fixed time points to maintain a stable drug concentration. The treatment usually lasts for 3-6 months.

2. Adjustment for special populations

Elderly patients do not need to adjust the dosage, but it is important to note that hand tremors may affect the accuracy of medication administration. Pregnant women lack safety data, and breastfeeding should be suspended.

3. Correct administration method

The tip of the dropper should avoid contact with the eyelid, and after dripping, press the lacrimal sac area for 1 minute. If other ophthalmic preparations are required, they should be separated from Catalin by at least 15 minutes.

4. Adverse reaction monitoring

The common brief stimulation usually subsides within 5 minutes. If there is persistent redness, blurred vision, or eyelid swelling, the medication should be stopped immediately and medical attention sought.

5. Storage requirements

Store in the dark below 25 ℃ and use within 4 weeks after opening. It is recommended to use a cold storage bag for drugs when carrying them out to avoid drug denaturation caused by high temperatures.

6. Taboos

It is contraindicated for individuals allergic to Pinoxicillin Sodium. Suspend use during acute eye infection, and caution should be exercised in patients with corneal injury after evaluation.

7. Principles for handling missed services

If a missed dose is found, it should be immediately replenished. If it is close to the next medication time, the current dose should be skipped. Never use double doses to compensate for missed doses at any time.

8. Specific time nodes

If the time until the next medication is more than 6 hours, immediately supplement the full dose once. If the time until the next medication is ≤ 6 hours, skip the missed dose and use the next dose according to the original plan.

9. Special precautions

After taking the supplement, it is still necessary to maintain the original medication interval. For those who take the medication four times a day, they need to wait for about 6 hours before taking the next dose.
