What is Best Drop for Allergic Conjunctivitis?
When I was a resident we had limited options to treat allergic conjunctivitis. Now we have many more options.
As of 2016 options include:
1. Cold ice packs with cold nonprescription artificial tears
2. Crolomn sodium
3. Olopatadine: called Patanol or Pataday
4. Alcaftadine 0.25%: called Lastacaf
5. Nonsteroidal drops
6. Steroid drops: varying strengths
There remains few studies comparing the above options head to head. Below are a couple of studies I found thus far.
Still it is possible that a patient respond better to one class of drop than another. Thus the frustration of sometimes having to try different options may be needed. In addition I have had many patients say they have used an particular drop for years with effect only to not have it work any more. Is this tolerance in some patients? Possibly but we do not for sure why this happens in some and not in others.
