I have mild asthma and have been on two different antibiotics during the past 2 months. The doctor seems to think some sinus/ upper respiratory infection is going on so is trying me on different meds. The first two were amoxicillian and then Biaxin. They work at first and then after a few weeks the symptoms are back again. I went on Saturday and the doctor wanted to put me on Levaquin for 5 to 7 days. I decided myself not to go on it as i was going on vacation a week later and didnt want any stomach issues beforehand. Well now it is 5 days later from the appointment and i have started with a cough and some kind of sinus/respiratory thing going on and beating myself up that i didnt start this medication on Saturday when i would have had a whole week to deal with the side affects before going away. What should i do?? Should i start today and see how i feel by tomorrow. I really didnt want to be taking meds while on my vacation but i know how this cycle goes and its not going to get any better.
