Yes, Metrogyl gel (Metronidazole) can be used if the acne (pimples) is related to rosacea, but it is not meant for common acne. Apply a thin layer of the gel to the clean and dry affected area once or twice daily, as advised by your doctor. Wash your hands before and after use, and avoid contact with your eyes and mouth.

Metrogyl Gel can sometimes be used for wound infections, but varicose vein ulcers usually need more than just an ointment. They often require proper wound assessment, special dressings, compression therapy to improve circulation, and antibiotics if infection is confirmed. Using Metrogyl Gel on your own is not recommended. It is best to have a doctor or wound care specialist examine the ulcer, confirm whether infection is present, and guide appropriate treatment to ensure safe healing.
