•At least three significant blisters at two or more body sites that have appeared in the week prior to study enrolment. Significant blisters are defined as intact blisters containing fluid which are at least 5mm in diameter. However, if the patient has popped a blister, or the blister is at a site that makes it susceptible to bursting such as the sole of the foot, it can be considered part of the blister count, providing there is a flexible (but not dry) roof present over a moist base.
•Free of blisters and any treatment for bullous pemphigoid for at least one year.
•Are the trial subjects under 18? no
•Number of subjects for this age range:
•F.1.2 Adults (18-64 years) yes
•F.1.2.1 Number of subjects for this age range
•F.1.3 Elderly (>=65 years) yes
•F.1.3.1 Number of subjects for this age range

•Received any of the study medications or other recognised systemic medications for the treatment of this episode of bullous pemphigoid prior to study entry. Prior topical treatment is permitted.
•Recent administration of a live virus vaccine.
•Mainly or entirely mucosal bullous pemphigoid.
•Known allergy to tetracyclines.
•Presence of any condition which precludes the use of either of the study drugs.
