Rozex – Metronidazole uses, dose and side effects

What Rozex gel is and what it is used for

Rozex gel contains metronidazole, which is an antibiotic that is active against only a few types of bacteria.

Rozex gel is used for redness and rashes in the skin disease rosacea. Rosacea is a skin disease that affects the central parts of the face (forehead, nose, cheeks, and chin) with redness, bumps, and blisters.
