Blog Metronidazole: Treats Skin Infections, Rosacea, and More

Metronidazole is an antibiotic that can be prescribed for various infections, including skin infections, rosacea, mouth infections, and stomach issues. It can also treat infected insect bites, wounds, and ulcers. It works by stopping the growth of the bacteria or parasites that cause the infection.

Here is the vital info:

  • Available by prescription only: You will need a doctor’s appointment or an online consultation and an Access Doctor GP evaluation to get Metronidazole prescribed.
  • Many forms: It comes in tablets, gels, creams, liquids, and even suppositories.
  • Common side effects: Look out for nausea, vomiting, diarrhoea, and a metallic taste in your mouth.
  • Alcohol is a no-no: Avoid alcohol while taking metronidazole and for two days after to avoid unpleasant side effects.
  • Relief timeline varies: While you might feel better in a few days for some infections, others, like rosacea, take longer.
  • Always finish the course: Do not stop taking metronidazole, even if you feel better, to ensure complete treatment.

Is Metronidazole suitable for everyone?

Metronidazole is a powerful antibiotic, but it is not suitable for everyone. Here is a quick guide to see if it is right for you:

It is generally safe for Most adults and children.

Talk to your doctor before using metronidazole if you:

  • Have allergies: Have you ever reacted badly to metronidazole or other medication?
  • Are pregnant or breastfeeding: Discuss risks and benefits with your doctor.
  • If you have liver problems, your doctor may need to adjust the dosage.
  • Are on dialysis: This treatment might affect how metronidazole works in your body.
  • Struggle to avoid alcohol: Metronidazole and alcohol don’t mix, so be honest with your doctor.

If you suspect a vaginal yeast infection (thrush), metronidazole won’t help, so discuss this with your doctor.

Metronidazole and Alcohol Don’t Mix

Metronidazole is a powerful antibiotic, but you should avoid consuming alcohol while taking it. This includes drinks, foods with alcohol content, and even mouthwashes containing alcohol. You should avoid consuming alcohol for two days after finishing your course to give your body enough time to completely process the medication before reintroducing alcohol.

Stick to this rule to avoid unpleasant side effects! If you have any questions about alcohol consumption while on metronidazole, consult your doctor or pharmacist.

Missed Metronidazole Dose?

We all forget to take medications sometimes. Here is what to do if you miss a dose of metronidazole tablets:

  • If you remember it soon, take it! If it is not nearly time for your next dose, take the missed dose as soon as you remember.
  • Don’t double up! If it is close to taking your next dose, skip the missed one and take your next dose at the usual time.
  • Resist the urge to play catch-up! Never take two doses at once to make up for a missed one.

If you often forget to take your regular dose, it can help to set an alarm. A phone or pillbox reminder can be handy. 

If you should take more than you need, accidental overdose is unlikely to cause harm. Taking an extra dose probably won’t cause any problems. But, if you are worried or take more than one extra dose, talk to your pharmacist or doctor for peace of mind.

How long until I feel better?

Metronidazole tackles infections, but how quickly you feel relief depends on the condition it is treating:

  • Most infections: You should feel better within a few days.
  • Serious swelling/Dental infections: Improvement starts within days, but symptom relief might take longer.
  • Stubborn infections: Some take a week to show improvement.
  • Rosacea: Be patient! It can take several weeks before you see a difference in your skin.

The key takeaway? Always finish your prescribed course of metronidazole, even if you feel better early on. This ensures the infection is fully cleared and prevents it from returning.
