I am currently on my 5th day of a severe spring allergy attack. If I only get these in the spring, would that mean it is a pollen allergy? I got it last spring too, very severe. It only affects my eyes & lips. They both get very swollen & itchy (burning type itch). I take Claritin D in the morning, but it is supposed to last 24 hours and it doesn't. THen in the early evening I have to take two Benedryl pills. Is that too much? If I don't take the benedryl, then I can't sleep & can't stop rubbing my eyes. I know the instructions say one a day, but that just doesn't work. Is it okay to take claritin & benedryl in the same day? I'm wondering if my insurance would cover Zyrtec or Allegra? Do those last all day???? Thanks in advance!!
