Mydfrin: A Comprehensive Medical Overview What is Mydfrin? Mydfrin (Phenylephrine hydrochloride ophthalmic solution) is a sympathomimetic medication used to dilate the pupils of the eye during certain eye examinations or surgeries. It belongs to a class of drugs known as alpha-adrenergic agonists, which work by constricting the blood vessels in the eye and increasing the flow of fluids, resulting in pupil dilation. Mydfrin is available as a prescription medication in the United States. Uses of Mydfrin Mydfrin is primarily used for ophthalmic purposes, including eye examinations and certain types of eye surgeries. It is also used as a diagnostic tool to evaluate for ocular conditions such as glaucoma, which can affect the fluid drainage in the eye. In many instances, Mydfrin is used alongside other drugs, such as anesthetics, to numb the eye before a procedure. Dosage of Mydfrin The dosage of Mydfrin varies depending on the type of procedure being performed and the patient’s age and weight. The usual recommended dose for adults is one to two drops of 2.5% solution in the affected eye(s), applied two to three times per day, as needed. The dose for children is adjusted accordingly. However, it is important to follow the doctor’s instructions regarding the dose and frequency of administration.
