Tonic water and quinine

Tonic water is not the same as plain sparkling water because it contains quinine and may contain substantial sugar.

Direct guidance

What to know or do

Check the label and serving size and use it as an occasional drink rather than a treatment for cramps. Medicinal quinine or concentrated products require clinical review.

What changes the answer

  • The exact ingredients and caffeine or alcohol shown on the label
  • Serving size and what else you have had across the whole day
  • Whether vomiting, diabetes, dehydration or another condition changes the plan

When to get individual help

Check the exact item or situation with a doctor, midwife, pharmacist or relevant clinician; the name of a broad category is not enough for a personal decision.
