Hello, Ornidazole is a nitroimidazole antimicrobial and antiprotozoal drug. Metronidazole is also nitroimidazole derivative. Take nutritious and balanced fibre rich diet. Sleep for 8 hours daily. Drink more than 8 glasses of water a day. Never pick or squeeze pimples. Rosacea treatment is focused on (1) to unclog pores (2) to kill microorganisms (3) to minimize oil. Wash your face twice daily with a mild cleansing soap or liquid. It will keep your skin clean and minimize sensitivity and irritation. Cleanse twice daily with a 5% benzoyl peroxide wash. An alternative for those who are allergic to benzoyl peroxide is 2% salicylic acid. A variety of mild peeling agents (scrubs, exfoliants, and masks) can be used. These products remove the outer layer of the skin and thus open pores. Retinol (derivative of vitamin A) can help promote skin peeling. To get rid of oil on your face and reduce the embarrassing shine, use a gentle astringent/toner to wipe away oil. Masks containing sulfur and other ingredients draw out facial oil. Antibacterial pads containing benzoyl peroxide have the additional benefit of helping you wipe away oil. Use a light skin moisturizer and water-based oil-free makeup. Your treating know about the dosage of the ornidazole. Hope this helps. Please write back for further queries. Wishing you good health.
