Nancy,

No most people only have to take them for a few years, usually less than 5. Generally you start out on a once a week basis, at the smaller doses, and then gradually build up to what is a maintenance dose and the frequency varies with the symptoms. I usually get a shot every week or 10 days during ragweed season, but back down to once a month during the winter months on the weeds, molds bottle, but continue with the dust mite one every couple of weeks year around. I also do all the other environmental suggestions for the dust mites, pillow covers, mattress covers, bare floor, etc. My allergies are better since I have been GF.

Hope this helps,

Marilyn

I am fortunate because I have someone who can give them to me at the house, versus having to go to the doctor's office each time. I had to go to his office for several years until I quit having such large local reactions.
