What are the most common side effects of antibiotics?

Antibiotics should only be used when prescribed by a doctor for some bacterial infections.

Anytime antibiotics are used, they can cause side effects.

Common side effects

These range from minor to very severe health problems and can include:

  • Rash
  • Nausea, vomiting and diarrhoea
  • Yeast infections (like Candida that can cause vagina thrush)
  • Antibiotic-resistant infection
More serious side effects
  • C. diff infection, which causes diarrhoea that can lead to severe colon damage and death
  • Severe and life-threatening allergic reactions.
Should I stop taking them if I get a side-effect?

No. Talk to your doctor, before stopping them – unless you very unwell.
