Ornidazole kills parasites and anaerobic bacteria that cause infections by damaging their DNA. Together, they treat your infection effectively.

Stop and contact your doctor at once if you develop pain, swelling or tenderness in a tendon — the Achilles tendon at the back of the ankle in particular. This group can damage tendons, and the risk is higher in older people and with steroids. Report any new numbness, tingling or burning in the hands or feet promptly. Tell your doctor about any change in mood, confusion or agitation. Avoid strong sunlight and use sun protection — this group makes the skin burn more easily. Finish the whole course; this group is heavily associated with antibiotic resistance and should be used only when prescribed. Finish the whole course even after you feel better. Do not drink any alcohol while taking metronidazole, ornidazole or tinidazole, or for the period after the course that your doctor states — the combination causes severe flushing, vomiting and a racing heart. Report severe or watery loose motions during or after the course rather than treating them yourself. Tetracyclines stain developing teeth and are avoided in young children and in pregnancy. Antibiotics do not work against colds, flu or most sore throats, which are caused by viruses.
Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Generally avoided in children and adolescents, in pregnancy, and in anyone with a history of tendon problems with these antibiotics.
Antacids, iron, zinc, calcium and milk markedly reduce absorption — separate them by at least two hours. Tell your doctor if you take steroids, a blood thinner or a medicine for heart rhythm. Antacids, iron, zinc and calcium reduce the absorption of tetracyclines — separate them by a couple of hours. Tell your doctor if you take a blood thinner.
Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
