What Is Metronidazole Gel Used For?

Metronidazole gel is approved for treating a skin condition called rosacea in adults. This medicated skin gel is specifically approved to treat the bumps and pimples caused by rosacea, although it may also help with redness and dryness. Metronidazole gel can also be used to reduce odor caused by certain types of wounds or tumors; however, these are unapproved uses for the medicine.

An Overview of Uses for Metronidazole Gel

Metronidazole gel (Metrogel®) is a prescription medication licensed to treat rosacea. Specifically, it is approved to treat the bumps and pimples caused by this condition. It may also help with associated redness or dryness, although it is not approved for treating these symptoms.
 
Rosacea is a chronic disease that affects the skin and sometimes the eyes. Characteristics of the condition include redness, pimples, and, in advanced stages, thickened skin. Although rosacea usually affects the face, it can also affect parts of the upper body. Despite how common the condition is, many people with rosacea go undiagnosed.
 
Rosacea treatment may involve good skin care (see Rosacea Skin Care), medications (either applied directly to the skin, like metronidazole gel, or taken by mouth), and other treatments like laser surgery. Metronidazole gel is most useful for people who have bumps and blemishes associated with rosacea.
 
Even for people taking rosacea medications, it is important to try to avoid triggers, such as alcohol, hot beverages, or spicy foods.
 

How Does This Medication Work?

At this time, it is not yet known how metronidazole gel works for treating rosacea. The active ingredient (metronidazole) is an antibiotic. Metronidazole may have some immune-suppressing and anti-inflammatory properties, which may help with rosacea as well.
