Expiration date of eye drops and medication dispensing issues?


Hello, Director Gao.
Due to my high myopia, I have been regularly visiting the glaucoma department at a designated hospital for follow-ups.
After undergoing surgery on my left eye at the end of October, I was prescribed steroid eye drops for inflammation.
However, on the evening of November 19, I noticed rainbow halos in my left eye, along with blurriness and a headache.
I returned to the hospital on November 20 to see a glaucoma specialist (not my original attending physician).
At that time, my left eye pressure was 32.2 mmHg and my right eye pressure was 17.3 mmHg.
The doctor prescribed a three-day course of oral medication and two types of eye drops to lower the pressure in my left eye, and scheduled an appointment with my attending physician for November 24.
The oral medication prescribed was Acetazolamide 250 mg/tablet, and the eye drops were: 1.
Co-Dorzomide Ophthalmic Solution (Dorzolamide 2% + Timolol 0.5% ophthalmic solution 5 mL/bottle) and 2.
ALPHAGAN P Ophthalmic Solution (Brimonidine ophthalmic solution 0.15% 5 mL/bottle).
On November 24, my left eye pressure was 9 mmHg and my right eye pressure was 14 mmHg (I had taken the oral medication the night before and only used the eye drops).
After the examination, my attending physician said there was no need for further oral medication, and I should continue using the eye drops.
I was scheduled to return on December 28 for pressure measurement and an OCT examination.
Since the eye drops were prescribed on November 20, the medication bag indicated that they should be used up by December 20.
Therefore, I would like to ask the doctor: 1.
Can I continue using the eye drops until my appointment on December 28? 2.
Is there a need to return earlier to see another doctor and obtain more medication? 3.
I heard from other doctors that eye drops prescribed for one eye need to be renewed after four weeks.
If the eye drops were prescribed on November 20, when is the earliest I can get a refill? (My attending physician is fully booked on December 21, and I can currently only schedule appointments with other glaucoma specialists on December 18 and 19.) Thank you in advance for your response, Director Gao.

Hello: 1.
It can be used until December 28.
2.
Please return for a follow-up appointment as directed by the physician.
3.
Four weeks is 28 days, so a new prescription can be issued on December 18.

When it comes to managing eye drops, especially in the context of glaucoma treatment and post-operative care, there are several important considerations regarding expiration, prescription management, and the timing of follow-up visits.

1. Expiration and Usage of Eye Drops: Eye drops typically come with an expiration date printed on the packaging. This date indicates the last day the medication is guaranteed to be effective. In your case, the eye drops prescribed on November 20th have a recommendation to be used by December 20th. It is crucial to adhere to this guideline to ensure the medication's efficacy. However, if you have not finished the drops by that date, you should not use them beyond the expiration date. Using expired medications can lead to reduced effectiveness and potential irritation or infection.

2. Continuing Eye Drops Until the Next Appointment: You mentioned the possibility of using the eye drops until your next appointment on December 28th. While it may seem convenient, it is essential to consider the expiration date. If the drops expire on December 20th, you should not use them beyond that date. Instead, it would be prudent to schedule an earlier appointment with your ophthalmologist or another qualified eye care provider to obtain a new prescription. This ensures that you have access to effective medication and can manage your eye pressure appropriately.

3. Follow-Up Appointments and Prescription Needs: If you feel that your symptoms are not adequately managed or if you experience any changes in your vision or discomfort, it is advisable to seek an earlier consultation. Given that you are under treatment for glaucoma, timely follow-ups are critical. If your primary doctor is unavailable, consider seeing another ophthalmologist in the same practice or a different clinic to ensure continuity of care.

4. Prescription Frequency and Regulations: Regarding the frequency of prescriptions for eye drops, it is common for ophthalmologists to limit the number of refills for certain medications, particularly those used for chronic conditions like glaucoma. This is to ensure that patients are monitored regularly and that any changes in their condition are addressed promptly. If your eye drops were prescribed on November 20th, the earliest you might be able to get a refill would typically be four weeks later, which would be around December 20th. However, this can vary based on the specific policies of your healthcare provider and the nature of your treatment.

In summary, it is essential to manage your eye drops carefully, adhering to expiration dates and ensuring that you have a continuous supply of medication. Regular follow-ups with your eye care provider are crucial for monitoring your condition and adjusting treatment as necessary. If you have any concerns or experience changes in your symptoms, do not hesitate to seek medical advice sooner rather than later. Your eye health is paramount, and proactive management is key to preventing complications.
