  • Effectiveness
    Slight (for dry eyes)
  • Side effects
    None
  • Adherence
    Always
  • Burden
    Not at all hard to take
Dosage: 0.25 mg Daily
Advice & Tips: This is the generic for Zaditor, but it does NOT work as well. I finally went to see a Cornea specialist, who recommended Restasis instead. Restasis enables me to actually see first thing in the morning and throughout the day. Now I only need moistening eye drops a few times a day.
Cost: < $25 monthly
