I missed an allergy shot, do I need to start over?

I've been on allergy shots for 3 months now. I missed an allergy shot and want to know if I have to start all over again. 

It's possible that you have to go back a step or two.
When getting allergen injections it is important to be consistent so that you can steadily build up your body’s tolerance to the allergen(s). If you miss an injection you may have to take a step or two back in your build-up schedule for safety reasons depending on how much time has passed since your last injection. This is a topic that should be discussed with your allergy specialist.
