How many days can one bottle of EIKANCE 0.01% Atropine Sulfate Eye Drops be used and the dosage instructions for different age groups?

0.01% atropine sulfate eye drops (EIKANCE) is a low-concentration atropine preparation mainly used to control the progression of myopia in children. Its low concentration makes the drug safer for long-term use and can significantly reduce eye discomfort and systemic side effects. As eye drops, the capacity of each tube is usually 5ml, and each drop is about 0.05ml, which provides a basis for daily dosage calculation.

As for the number of days of use, children generally only need one drop in each eye per day, that is, a total of two drops per day. Calculated based on one 5ml eye drop, each drop is about 0.05ml. The total amount of two drops used per day is about 0.1ml. Therefore, one bottle of medicine can theoretically be used for about 50 days. However, the actual number of days of use may be slightly reduced due to the method of eye drops, liquid residue, spillage, or children's non-cooperation. It is generally recommended to use it in a cycle of 40–45 days to ensure sufficient liquid medicine.

In terms of dosage for different age groups, official and clinical guidelines generally recommend low-concentration atropine for myopia intervention in children and adolescents, especially children aged 6 to 12 are the main applicable group. Children under the age of 6 must be used under the strict guidance of a doctor, and intraocular pressure, pupil changes and visual acuity should be monitored regularly. Adolescents over 12 years old can usually continue to maintain one drop a day. However, if myopia has progressed significantly or there are special individual needs, the dosage or frequency of use can be adjusted under the evaluation of a doctor.

In general, each tube of 0.01%Atropine Sulfate Eye Drops (EIKANCE) lasts approximately 1 to 1.5 months, depending on the child's eye-dropping habits and drop consumption. The principle of medication emphasizes individualization and safety. It is mainly suitable for children aged 6 to 12 years old. It needs to be used under the guidance of a professional ophthalmologist, and the axial length, diopter and intraocular pressure should be reviewed regularly to ensure the effectiveness and safety of the medication.
