Metronidazole cream is a topical treatment, meaning it is applied to the skin. There are also pill treatments of the drug metronidazole that are taken orally. The cream is used as a treatment for adult acne. It is also used to treat bacterial vaginosis, according to the University of Michigan Health System. Bacterial vaginosis is a change in the levels of bacteria that normally reside in the vagina. According to the American Society for Microbiology, metronidazole cream is usually well-tolerated by patients. Most people experience no side effects, although a few do.
Common Side Effects
The common side effects of metronidazole cream include headaches, dizziness, nausea, vomiting, drowsiness and the development of a rash. Dry mouth and a metallic taste in the mouth are additional side effects, but these are more generally associated with metronidazole taken orally.
Yeast Infection
A vaginal yeast infection is a side effect for metronidazole cream when used as a vaginal treatment. The infection can occur during or after treatment. When it is used as a vaginal treatment, barrier birth control methods such as latex condoms and diaphragms should not be trusted because the mineral oil in the cream can break down the latex.
Other Side Effects
According to the National Library of Medicine, side effects of metronidazole cream also include a stinging or burning feeling on the skin. Skin can become irritated or dry as a result of using the cream.
