We've had several members get cataracts due to prednisone. Today I got an email newsletter from JHU that lists the 5 common causes of cataracts. Here's the link to read about all of them. I copied the one concerning pred usage.
I'm sharing this because I was always wondering how much pred caused cataracts or if it was totally arbitrary. I thought others might be wondering the same thing.
Cataract Risk Factor #2: Corticosteroids. Long-term use of corticosteroids, especially at high doses, is the most common drug-related cause of cataracts. In a study of individuals taking oral prednisone for one to two years, cataracts developed in 11% of those taking less than 10 mg a day, 30% of those taking 10 to 15 mg a day and 80% of those taking more than 15 mg a day.
Now you know!
