There is no specific labeling of which medications are pediatric-specific eye drops. However, parents can choose preservative-free pediatric eye drops for treatment. The instructions state the usage and dosage for children, and parents should use eye drops for children under the guidance of a medical professional. Routine eye drops include tobramycin drops and others. Clinical trials have proven that these antibiotics have no significant effect on the growth and development of children. When eye drops are administered, the drops sometimes flow down the nasolacrimal duct into the pharynx. Children may have a bitter taste in their mouth. This is can be removed by gargling with water to remove any residual drops in the mouth. When children have eye problems or experience any discomfort during the use of eye drops, it is recommended that they visit a hospital promptly for diagnosis and treatment by a medical professional.
