How long and how often should i receive allergy shots?

1-6 months: Allergy shots help animal and pollen allergy sufferers the most to reduce their misery. Once a maintenance dose is reach (a process that can taken 1-6 months), injections are spaced out to a 2-4 week interval as part of a maintenance plan. Injections that do not seem to be effective after a year may be discontinued. Injections may be continued for 3-5 years or longer if they are effective.

Allergy shots: The building process usually requires injections once per week (unless rush or cluster immunotherapy) until maintenance is reached, then you will receive allergy injections every 2-4 weeks. Therapy is usually 3-5 years but can be shorter or longer based on results.
