keratoconjunctivitis sicca
"The first and second evening after beginning use of Restasis I experienced severe bloating.  By the third day I felt a wheezing sensation in my throat and diarrhea.  By the fourth day I was doubled over with severe stomach pains, diarrhea and vomiting.  Symptoms continued for six days when my doctor ordered blood work, urinalysis, and stool sampling.  Results showed a high white blood cell count and a high eosinophilia count.  A few days later I was admitted to the hospital for severe dehydration due to continued vomiting and diarrhea. A colonoscopy and endoscopy were performed along with a biopsy of stomach wall to rule out a parasite infection.  Diagnosis concluded a suffered a severe allergic reaction to Restasis."
