How should I prepare for allergy shots?

ANSWER

You may want to avoid exercise or doing anything strenuous for 2 hours before and after your appointment. That’s because exercise boosts blood flow to the tissues and may cause the allergens to spread throughout your body faster. It’s not likely to cause a serious problem, but it’s best to be safe.
