• Gonococcal arthritis
• Leprosy (for minocycline)
• Lyme disease (for doxycycline and tetracycline)

For patients taking this medicine for SIADH :

• Some doctors may prescribe demeclocycline for certain patients who retain (keep) more body water than usual. Although demeclocycline works like a diuretic (water pill) in these patients, it will not work that way in other patients who may need a diuretic.
