I Was Treated For Brocchontis (if I Spelled It Correctly)

I was treated for brocchontis (if I spelled it correctly) and was given prescriptions for these medications:
Doxycycline Hyclate 100mg: Benzonatate 100mg; also a nasal spray Azelastine 0.1%. After taking this medication for several days I have began to itch at urinating. I found this tube with my other medicine and was wondering if it was safe to use?
