Oracea is a special prescription drug owned by Galderma that is the 'only oral prescription approved by the FDA for rosacea' and is doxycycline with an enteric-coated tablet that releases timed release beads of 10 Mg of doxycycline and 30 mg of immediate doxycycline. The claim is made that this low dose submicrobal is not antibiotic treatment but instead is anti-inflammatory. Nevertheless, you should read the product insert which comes with every prescription for Oracea which has the same warnings for doxycycline for risks and side effects. The safety limit tested for Oracea was nine months.
