Allergic reaction to doxycycline hyclate for lyme disease?

Allergic Reaction: Stop the Doxycycline and call your doctor. Many allergic reactions are mild, while others can be severe and life-threatening. They can be confined to a small area of the body, or they may affect the entire body. The most severe form is called anaphylaxis or anaphylactic shock. Allergic reactions occur more often in people who have a family history of allergies.

Check with doctor: There are alternative antibiotics that you can take instead of doxycycline. Check with the doctor who prescribe it.
