Mydfrin Information

Mydfrin (phenylephrine hydrochloride) is an ophthalmic solution that dilates the pupil (mydriasis) during eye examinations. By stimulating the alpha-adrenergic receptors in the eye, Mydfrin causes the iris muscle to relax, leading to pupil dilation. It is also a decongestant and constricts blood vessels in the eye. This action allows a clearer view of the retina and other internal eye structures during diagnostic procedures such as fundoscopy or slit-lamp examination. Mydrfin can also be used in low doses to relieve eye redness, dryness, burning, and irritation caused by wind, sun, and other irritants. Mydfrin is commonly used in eye care settings to help professionals assess eye health, detect retinal disorders, or prepare the eye for specific surgical procedures. It is a powerful tool for temporary pupil dilation but does not treat underlying eye conditions or disorders. The effects of Mydfrin are typically short-lived, and the eye will return to its standard size after a few hours.

Mydfrin Directions:

Follow the instructions provided by your healthcare provider or those indicated on the product label. The typical directions for use are as follows:
1. Wash your hands thoroughly before use.
2. Open the vial and avoid touching the tip to any surface.
3. Tilt your head back slightly and gently pull down the lower eyelid to form a small pocket.
4. Instill one or two drops into the affected eye(s) as directed.
5. Close your eyes gently and blink to distribute the solution evenly.

Eye care professionals typically use Mydfrin in a clinical setting. The effects of pupil dilation may last several hours, so avoid activities requiring clear vision during this time, such as driving. Discard any unused solution after the procedure. If you use contact lenses, remove them before applying this medication. Wait at least 15 minutes before reinsertion. Store Mydfrin at room temperature (15-25°C) away from light, keeping the vial lid closed tightly. Do not reuse the vial if it has been opened previously, as contamination could occur.

Mydfrin Precautions:

Do not use Mydfrin if you are allergic to phenylephrine or other ingredients in the formulation. Inform your doctor if you have:
• A history of glaucoma, exceedingly narrow-angle glaucoma;
• Asthma or sulfite allergy;
• Cardiovascular conditions such as heart disease, high blood pressure, or arrhythmias;
• Eye infections or eye injuries, recent eye surgery

Mydfrin may interact with other medications, so inform your healthcare provider about any other treatments you are using, especially MAOIs, tricyclic antidepressants, blood pressure medications, or systemic atropine. Avoid wearing contact lenses while using Mydfrin unless instructed by your doctor, as this may interfere with the medication's effects. Pregnant or breastfeeding individuals should consult their healthcare provider before using Mydfrin to ensure it is appropriate for their needs. Your vision may blur temporarily after using this medication. Do not drive or operate heavy machinery until your vision has cleared.
