Patients with excessive facial hair (beards, sideburns, moustaches, etc.) that would interfere with the diagnosis or assessment of rosacea. 3. History of hypersensitivity or allergy to Metronidazole, or other ingredients of the formulation. 4.

Use of the following within 1 month prior to the baseline visit: * Topical Retinoids to the face * Systemic antibiotics known to have an impact on the severity of facial Rosacea * Systemic Steroids 6. The use of anticoagulant therapy within 14 days prior to baseline. 7. The use of any antipruritics, including antihistamines within 24 hours of any study visits. 8. History of blood dyscrasia. 9. Ocular rosacea (e.g., conjunctivitis, blepharitis, keratitis) of sufficient severity to require topical or systemic antibiotics. 10.
