Treatment
If you present signs of dehydration, it is important to hydrate yourself and replenish your mineral salts. You need to drink more liquid, such as water, or a rehydration solution. Don’t hesitate to seek advice from a pharmacist or call Info-Santé 811, option 1.
If you or your child presents signs of moderate to severe dehydration, you must go to the emergency department immediately.
