Allergic Rhinitis
"I was prescribed this for headaches and eye irritation for allergies.  Been  taking it for a month.  No improvement or change in symptoms.  Drs office said it takes a few days to help symptoms ; pharmacist said it can take 4-6  weeks to build up on in your system.  The generic is cheap but after a month,  no change.  Don&#039;t know if its med not working or mis diagnosis"
