Common Side Effects of Metronidazole
Before you start taking metronidazole, it's important to tell your doctor if you have any allergies. He or she should also know what medicines you are taking (including over-the-counter and herbal treatments) and what medical conditions you have. Before you take metronidazole, tell your doctor if you have had Crohn's disease or a blood, kidney, or liver disease.

Also be sure to tell your doctor if you are breast-feeding or pregnant before taking metronidazole. If you get pregnant while taking metronidazole, make sure you tell your doctor right away.

You should also be honest with your doctor about your alcohol use before taking metronidazole. You cannot drink alcohol when taking metronidazole. Drinking alcohol when taking metronidazole will cause you to have side effects such as vomiting, flushing, or headaches, among others. Be aware that some over-the-counter medicines, such as cold medicines, contain alcohol and can trigger the same side effects when you are taking metronidazole.

Metronidazole can cause some side effects. Be sure to tell your doctor if you get the following symptoms and they are severe or won't go away when you are taking metronidazole:
  • Stomach symptoms, such as vomiting, nausea, diarrhea, and loss of appetite
  • Headaches
  • Irritability
  • Trouble sleeping and irritability
  • Dry mouth, furry tongue, mouth or tongue irritation, or a metallic taste in your mouth
Some patients have reported that their hands and feet felt numb or tingly when taking metronidazole.

Get medical help right away if you break out in a rash or are itching when taking metronidazole. The same is true if you experience a stuffy nose, fever, or pain in your joints.
