Description of Mydfrin

The drug Mydfrin falls under the category of drugs known as mydriatics. The main role of Mydfrin eye drops is to constrict the blood vessels in the eyes. Some other key functions of Mydfrin include enlargement of the pupils, enhancing fluid drainage from the eyes, and curbing fluid production in the eyes. The generic name of Mydfrin is phenylephrine ophthalmic.

Mydfrin is available as an over-the-counter drug, which is mild in terms of strength. It is also available as a prescription drug, which possesses a higher strength.

Indications & Dosage of Mydfrin

The over-the-counter version of Mydfrin is generally indicated for problems like dryness, itching and burning sensations in the eye that occur due to minor irritants. The prescription version of Mydfrin is indicated for constricting the ocular blood vessels in patients suffering from glaucoma or those who are to undergo an eye examination or surgery.

The Mydfrin dosage should be strictly administered as per the doctor’s prescription or recommendations. Contact lens users should be careful as Mydfrin is known to contain a preservative which may discolor contact lenses. Application of the eye drops is rather simple. The head should be tilted back and the lower eyelid should be pulled down. The dropper should be positioned above the eye, and a drop should be squeezed out.

The continuous use of Mydfrin beyond a period of 72 hours is not recommended and may cause severe ocular damage. Discolored eye drops should not be used as they can cause infections. The eye drops should be stored at room temperature, away from heat and moisture.
