Cephalexin
"I have asthma and have had respiratory problems my whole 27 years. When I get sick, I get sick as a dog for long periods of time. Needless to say, I have been prescribed to several different antibiotics over the years and each of them helped. However, everytime I have taken cephalexin I have noticed an almost immediate result. So immediate that it is shocking. Currently, I am prescribed 500mg 3x per day for 10 days and I haven't had any side effects aside from feeling tired but every antibiotic does that to me. Cephalexin is by far the best antibiotic I have had. Everyone reacts differently though so we all have to find which medications work best for our bodies."
