Hi, I am travelling in India and have a chest infection and told the doctor I usually take Xithromax. He has given me the generic, Azithral, 250mg. I am bit nervous of taking this as tend to react badly to some medications (am hypersensitive). I am also asthmatic, have recently had whooping cough (which I am still recovering from) and am allergic to penicilin. In addition to this, I am not sure how many tablets to take. He arranged with the hotel to collect the tablets, and when they arrived, it was in a brown packet, with 10 x 250mg pills in Azithral blister pack (from the hospital accross the road). Should I take one twice a day for five days? (If I should take them at all?) I saw the doc two days ago and actually feel worse today so feel like I really do need antibiotics, all things considered.
