I live in the UK and suffer with severe hayfever. The last three years and twice about 13 years ago I have had 40mg of Kenalog, it is wonderful!.
From March I take antihistamins, nasal spray and eye drops and have even tried acupunture to try and releive my symptons but nothing works apart from Kenalog.
I have tried long and hard to find out long term side effects but there seems to be no formal study done of this drug. It is a risk, but I am fed up with spending 6 months of the year sneezing, eyes wateringm, asthma and feeling generally rubbish. Kenalog works for me it is like magic, within 2 days all my symptoms dissapear. Fortunatley I have never suffered from any side effects. Although my doctor is not over keen on me having it he understands I cannot do my job properly when I am suffering so badly with hayfever.
