DIY eye (and ear) drops for treating infection
« on: October 22, 2017, 09:47:23 AM »
Good article from the WHO on the small scale preparation of eye drops: http://apps.who.int/iris/bitstream/10665/67840/1/WHO_PBL_01.83.pdf

The one I thought likely to be of the most value was the povidone iodine (1%) solution for treating conjunctivitis, whether viral or bacterial.  Even better is the prep steps for that solution are the easiest as it doesn't require sterilization, and the two ingredients themselves are very shelf-stable (sterile saline and Betadine).  It's always been a challenge trying to keep a supply of antibiotic eye drops/ointments as they expire so quickly compared to oral antibiotics, in fact in recent years I gave up stocking them altogether.

Anyway, these went in the cart this morning:

Eye drop bottles: https://www.amazon.com/gp/product/B00V1X1LHG
Syringes for measuring/filling:  https://www.amazon.com/gp/product/B01CFJ51X4

We already stock sterile saline, but if you don't and just need some in small quantities then these might be a good option:  https://www.amazon.com/PosiFlush-Pre-Filled-Syringes-Luer-Lok-Without/dp/B005OSZ5E4  And the betadine of course.

Also found this digging around this morning, the 5% povidone iodine/Betadine solution is also very effective for treating middle ear infections (chronic form for certain and presumably the acute as well):  http://jima.imana.org/article/viewFile/5986/38_3-4   So it's a twofer! :)

Update...



PVP-I solution in the center, and clockwise from the top:

.22 micron luer-lock syringe filters (handy if sterile water/saline isn't available)
0.9 sodium chloride for injection, 10ml IV lock flush syringes and 100ml bags
Eye drop bottles/caps
1ml, 3ml, and 10ml syringes with adapters and luer-lock blunt needles

Most of this has multiple uses beyond just eye/ear drops of course, and some I already had stored for other uses, but just filling in some gaps in the medical preps.  Like I mentioned, I gave up trying to keep antibiotic eye/ear drops in stock because of a concern over the short shelf-life of liquids/ointments - wasn't comfortable with using expired eye drops and throwing the old ones away and buying replacements every year or two gets expensive - so having the ability to make them using shelf-stable and long life ingredients made sense.
