hello doctor, my daughter has been taking montek lc for allergies for the last 2 years. she is 20 yrs old. she recently has started experiencing blurred vision when she reads a lot. from not being able to continuously read for not more than 2 hours, now in 2-3 weeks it is down to less than 15-20 minutes now. we met with a couple of eye specialists and they have diagnosed as dry eyes and given her some eye drops, but also said that any antihistamines being taken, can also cause dry eyes. can you throw some light on the antihistamines like montek lc and that resulting in side effects like blurred vision? thanks in advance. - bhaskar
