Hi, I can t distinguish if I have a cold, flu, or allergies. Nasal congestion, coughing sparingly, head and behind my eyes hurt when I cough, runny nose and watery eyes I m not coughing up anything, but the last time I sneezed about an hour ago, I can tell I disturbed some phlegm in my throat/chest. I just check and have a fever of 100.4, last night it was 101.0 I took Tylenol for the temp and headache. I took Loratadine this morning (24hr tablet). I feel like it is not working. The pharmacist suggested I take Allegra. Can I take it before the 24 hours in up with the Loratadine? Does this sound like a cld? Flu? or Allergies? - Thank you!
