Medical disclaimer.

Applies to everything published at drdavidjustinhernstadt.com, including the Eye Drop Taper Calendar.

Not a clinical consultation

The information on this site is published for general educational and informational purposes only. It is not medical or clinical advice, and it is not a substitute for consultation with a qualified physician.

Reading this site does not establish a doctor and patient relationship between you and Dr David Justin Hernstadt. Every patient's eyes, medical history and risk profile differ, and a proper assessment requires an in-person clinical examination.

About the Eye Drop Taper Calendar

The tool reproduces a tapering schedule that your own clinician has already prescribed. It does not decide doses, does not recommend medication, and does not generate medical advice.

If what the calendar shows differs from what you were told in clinic, follow your clinician's instructions and contact the clinic. Do not change, stop or extend a course of eye drops based on this site.

The tool runs entirely in your browser. Your medication, your dates and anything you type are never uploaded or stored by us.

If you agree to it, the tool counts how many plans are built, using Google Analytics. That count carries nothing about you or your treatment, and declining leaves the tool working exactly the same.

Not an emergency service

If you have sudden loss of vision, severe eye pain, an eye injury, or sudden onset of flashes, floaters or a shadow across your vision, seek urgent in-person care. In Singapore, call 995 for emergency services or attend the nearest Accident and Emergency department.

This site is not monitored, offers no contact channel, and must never be used to report a medical problem or seek urgent help.
