, Very sorry to hear about your plight! The medication that caused my teeth to fall out was SINGULAIR 10mg. Ive been a chronic asthmatic since a .Child . I use 3 inhalers & only have 70% breathing capacity as my lungs are scared due to having Pneumonia 1r0 times & scores of chest infections ! Iam not an invalid & can still walk long distances in an emergency with my Ventolin inhaler, should read 10 times keyboard knackered, Whats Z pack ? You must have a severe allegy problem , have you tried Claritsyn ? I once visited S/CAL in1980 for 6 weeks we stayed at my uncles home and my asthma & eczema disappeared ! {RUBYSTARS}
